[0025] See also Figure 1 , Figure 1 A flowchart of a firmware upgrade method proposed in one embodiment of the present application is shown, which is used for an electronic device. The method includes:

[0026] S110. Receive the differential upgrade package sent by the cloud.

[0027] The differential upgrade package is obtained by performing differential calculation on the first firmware upgrade package and the second firmware upgrade package of different versions through a target differential algorithm; the target differential algorithm is determined based on at least one of the computing resources of the electronic device, the size of the first firmware upgrade package, the size of the second firmware upgrade package, the size of the upgrade package difference data, and the target data type; the first firmware upgrade package is the firmware upgrade package corresponding to the firmware installed on the electronic device; the upgrade package difference data refers to the difference data between the first firmware upgrade package and the second firmware upgrade package; the target data type is the data type to which the data in the first firmware upgrade package and / or the second firmware upgrade package belongs. The data type may include multimedia data or text data, etc.

[0028] The electronic device in this embodiment can be a smart phone, a tablet computer, a laptop computer, a desktop computer, an intelligent voice interaction device, a smart home appliance, a vehicle terminal, an aircraft, etc., but is not limited thereto.

[0029] The cloud can be a server that is connected to electronic devices and provides firmware upgrade packages for electronic devices. The server can be an independent physical server or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content distribution networks (CDN), as well as big data and artificial intelligence platforms.

[0030] A firmware upgrade package is a software package used to update or upgrade the firmware of an electronic device. It contains new firmware programs, drivers, and other necessary files to update the software version of the electronic device from the old version to the new version. This process usually requires following specific steps and instructions to ensure that the device is not damaged during the upgrade process. The purpose of the firmware upgrade package is to improve the performance and functionality of the device, fix possible vulnerabilities and problems, and enhance the security of the device.

[0031] The firmware upgrade package in the present application may be a firmware upgrade package for some modules in the electronic device (for example, a graphics processor, an audio processor, etc. in the electronic device), or may be a firmware upgrade package for the entire electronic device.

[0032] The first firmware upgrade package is an upgrade package corresponding to the firmware installed in the electronic device, that is, the firmware currently used by the electronic device is obtained by installing the first firmware upgrade package. The first firmware upgrade package and the second firmware upgrade package have different versions. Generally speaking, the version of the second firmware upgrade package is higher than the version of the first firmware upgrade package, that is, the first firmware upgrade package is an old version of the firmware upgrade package, and the second firmware upgrade package is a new version of the firmware upgrade package. In other embodiments, the first firmware upgrade package may also be a new version of the firmware upgrade package, and the second firmware upgrade package may be an old version of the firmware upgrade package, thereby realizing firmware restoration.

[0033] The cloud can send a first firmware upgrade package to an electronic device, and the electronic device installs the first firmware upgrade package to implement a firmware upgrade of the electronic device through the first firmware upgrade package. At the same time, the cloud can record the version of the first firmware upgrade package. After obtaining a firmware upgrade package with a different version from the first firmware upgrade package, the firmware upgrade package with a different version from the first firmware upgrade package can be used as a second firmware upgrade package, and then the first firmware upgrade package and the second firmware upgrade package with different versions are differentially calculated through a target differential algorithm to obtain a differential upgrade package, and the differential upgrade package is sent to the electronic device.

[0034] It is worth mentioning that when the cloud obtains a second firmware upgrade package with a higher version than the first firmware upgrade package, it can obtain upgrade prompt information and send the upgrade prompt information to the electronic device. When the electronic device returns an upgrade instruction based on the upgrade prompt information, the cloud performs a differential operation on the first firmware upgrade package and the second firmware upgrade package with different versions through a target differential algorithm to obtain a differential upgrade package. Among them, the electronic device can display the upgrade prompt information, and then the electronic device can return the upgrade instruction in response to the confirmation operation of the upgrade prompt information. Among them, the confirmation operation of the upgrade prompt information can be clicking on the upgrade prompt information, long pressing the upgrade prompt information, etc., which is not limited in this application.

[0035] In another embodiment, the cloud can receive the recovery request from the server and obtain the second firmware upgrade package corresponding to the reply request. At this time, the version of the second firmware upgrade package may be no higher than the version of the first firmware upgrade package. After that, the cloud performs a differential operation on the first firmware upgrade package and the second firmware upgrade package of different versions through a target differential algorithm to obtain a differential upgrade package. The reply request may include version indication information, and the cloud obtains the second firmware upgrade package according to the version indication information, wherein the version indication information may be a version number, a version name, etc.

[0036] In the present application, upgrade package difference data between the first firmware upgrade package and the second firmware upgrade package may be determined by a target difference algorithm as a differential upgrade package.

[0037] The corresponding target differential algorithm can be determined based on at least one of the computing resources of the electronic device, the size of the first firmware upgrade package, the size of the second firmware upgrade package, the size of the upgrade package difference data, and the target data type, wherein the computing resources of the electronic device include at least one of the central processing unit resources, the memory resources, and the hard disk resources. The differential algorithms involved in this application may include the BSDi ff algorithm, the XDelta3 algorithm, the HDi ffPatch algorithm, etc.

[0038] The computing resources of the electronic device are different, and the selected target differential algorithm is different. For example, when the computing resources of the electronic device are large, the HDi ffPatch algorithm can be determined as the target differential algorithm. When the computing resources of the electronic device are small, the BSDi ff algorithm or the XDe l ta3 algorithm can be determined as the target differential algorithm.

[0039] When the size of the upgrade package difference data is different, the determined target difference algorithm is different. For example, when the upgrade package difference data is small, the HDi ffPatch algorithm can be determined as the target difference algorithm. When the upgrade package difference data is large, the BSDi ff algorithm or XDe l ta3 algorithm can be determined as the target difference algorithm.

[0040] When the size of the firmware upgrade package is different, the determined target differential algorithm is also different. For example, when the firmware upgrade package (the first firmware upgrade package, the second firmware upgrade package, or the merged upgrade package of the two) is small, the HDiffPatch algorithm can be determined as the target differential algorithm. When the firmware upgrade package (the first firmware upgrade package, the second firmware upgrade package, or the merged upgrade package of the two) is large, the BSDi ff algorithm or the XDe l ta3 algorithm can be determined as the target differential algorithm.

[0041] When the target data type is different, the selected target differential algorithm may also be different. Exemplarily, when the target data type is a multimedia data type (such as pictures, audio or video, etc.), it means that the data redundancy in the first firmware upgrade package and the second firmware upgrade package is very high, and the target differential algorithm may include a data compression algorithm and a combination of the aforementioned three differential algorithms, that is, firstly perform data compression through a data compression algorithm, and then perform differential operations through the aforementioned differential algorithms to implement differential operations of the target differential algorithm and obtain a differential upgrade package; wherein the compression algorithm may include a png data compression algorithm and an inter-frame prediction algorithm, etc.

[0042] For example, the target differential algorithm is a combination of the png data compression algorithm and the XDe l ta3 algorithm, that is, the first firmware upgrade package and the second firmware upgrade package are compressed by the png data compression algorithm, and then the compressed first firmware upgrade package and the compressed second firmware upgrade package are differentially operated by the XDe l ta3 algorithm to obtain a differential upgrade package.

[0043] Exemplarily, when the target data type is a character data type, it indicates that the data redundancy in the first firmware upgrade package and the second firmware upgrade package is not high, and data compression does not need to be performed through a data compression algorithm. One of the BSDiff algorithm, XDe l ta3 algorithm, and HDi ffPatch algorithm can be directly selected as the target differential algorithm, that is, the differential operation is directly performed through the aforementioned differential algorithm to implement the differential operation of the target differential algorithm and obtain a differential upgrade package.

[0044] Of course, the target differential algorithm may also be determined by combining the computing resources of the electronic device, the size of the first firmware upgrade package, the size of the second firmware upgrade package, the size of the upgrade package difference data, and multiple items of the target data type.

[0045] For example, since the BSDi ff algorithm has stable performance, simple implementation, and low resource consumption, when the upgrade package difference data is small and the computing resources of the electronic device are small, the BSDi ff algorithm is determined as the target difference algorithm.

[0046] For example, the XDe l ta3 algorithm has complex parameters and a high compression rate, but it also has high requirements for memory and hard disk. Therefore, when the first firmware upgrade package is large, the second firmware upgrade package is large, and the computing resources of the electronic device are large, the XDe l ta3 algorithm is determined as the target differential algorithm.

[0047] For example, the HDi ffPatch algorithm has a better differential effect when the data volume is large, the CPU requirements are relatively high, and the difference between the new and old versions is relatively large; then when the upgrade package difference data is large, the first firmware upgrade package is large, the second firmware upgrade package is large, and the computing resources of the electronic device are large, the HDi ffPatch algorithm is determined as the target differential algorithm.

[0048] S120 , performing a restoration operation based on the differential upgrade package and the existing firmware upgrade package using a target restoration algorithm corresponding to the target differential algorithm to obtain a target firmware upgrade package.

[0049] The existing firmware upgrade package is obtained after the electronic device stores the first firmware upgrade package.

[0050] After the electronic device obtains the first firmware upgrade package, the firmware of the electronic device can be upgraded through the first firmware upgrade package, and then the first firmware upgrade package is directly stored locally to obtain an existing firmware upgrade package. At this time, the data in the existing firmware upgrade package is exactly the same as that in the first firmware upgrade package.

[0051] In some embodiments, after the electronic device performs a firmware upgrade on the electronic device through the first firmware upgrade package, the first firmware upgrade package can also be stored in the format of a drive letter device, and the stored data is an existing firmware upgrade package. At this time, the data in the existing firmware upgrade package is not exactly the same as the data in the first firmware upgrade package.

[0052] The electronic device can obtain a target restoration algorithm corresponding to the target differential algorithm from the cloud, and then perform a restoration operation based on the differential upgrade package and the existing firmware upgrade package through the target restoration algorithm to restore a target firmware upgrade package that is consistent with the second firmware upgrade package.

[0053] It is worth mentioning that if the existing firmware upgrade package is obtained by directly storing the first firmware upgrade package, the target restoration algorithm is used to directly perform a restoration operation based on the differential upgrade package and the existing firmware upgrade package to restore the target firmware upgrade package that is consistent with the second firmware upgrade package; if the existing firmware upgrade package is obtained by storing the first firmware upgrade package in the format of a drive letter device, it is necessary to take out the existing firmware upgrade package, and then convert the format of the existing firmware upgrade package to obtain a preprocessed firmware upgrade package that is consistent with the data format of the first firmware upgrade package, and then the target restoration algorithm is used to perform a restoration operation based on the differential upgrade package and the preprocessed firmware upgrade package to restore the target firmware upgrade package that is consistent with the second firmware upgrade package.

[0054] In some embodiments, before S120, the method further includes: receiving a configuration file sent from the cloud; the configuration file includes a target algorithm identifier corresponding to the target differential algorithm; and obtaining a target restoration algorithm corresponding to the target differential algorithm from a locally stored algorithm set according to the target algorithm identifier.

[0055] The cloud may send the configuration file and the differential upgrade package to the electronic device at the same time, or the cloud may send the configuration file and the differential upgrade package to the electronic device at different sending times, which is not limited here.

[0056] The target algorithm identifier is used to indicate the target differential algorithm, and different differential algorithms are indicated by different algorithm identifiers. The algorithm identifier can be the name, category or label of the differential algorithm, etc., which is not limited in this application. For example, when the target differential algorithm is the HDiffPatch algorithm, the target algorithm identifier is "HDiffPatch algorithm". For example, when the target differential algorithm is a combination of the png data compression algorithm and the HDiffPatch algorithm, the target algorithm identifier is "png data compression algorithm + HDiffPatch algorithm".

[0057] One differential algorithm corresponds to one restoration algorithm, and the differential algorithm and restoration algorithm with corresponding relationship are used to perform differential operation and restoration operation respectively: the differential algorithm is used to perform differential operation on data, and the restoration algorithm corresponding to the differential algorithm is used to perform restoration operation on the data after the differential operation of the differential algorithm, so as to restore the data.

[0058] For example, the restoration algorithm corresponding to the differential algorithm BSDi ff algorithm is the BSPatch algorithm, that is, the BSDi ff algorithm is used to perform differential operations on data, and the BSPatch algorithm is used to perform restoration operations on the data after the differential operation of the BSDi ff algorithm, so as to restore the data.

[0059] The algorithm set may store restoration algorithms corresponding to different algorithm identifiers, wherein the restoration algorithm corresponding to an algorithm identifier is the restoration algorithm corresponding to the differential algorithm indicated by the algorithm identifier, and the restoration algorithm corresponding to the target algorithm identifier of the target differential algorithm is used as the target restoration algorithm. For example, when the target differential algorithm is the BSDi ff algorithm, the restoration algorithm corresponding to the algorithm identifier of the BSDi ff algorithm is the BSPatch algorithm, and the BSPatch algorithm is the target restoration algorithm.

[0060] That is to say, the electronic device stores the target restoration algorithm locally, so there is no need to send the target restoration algorithm to the cloud. Only the target algorithm identifier of the target differential algorithm needs to be sent. The amount of data of the target algorithm identifier is much smaller than the amount of data of the target restoration algorithm, thereby reducing the data sent from the cloud to the electronic device, improving data transmission efficiency, and reducing network transmission pressure.

[0061] S130: Perform firmware upgrade via the target firmware upgrade package.

[0062] After obtaining the target firmware upgrade package, the firmware upgrade can be performed through the target firmware upgrade package to upgrade the firmware of the electronic device.

[0063] Generally speaking, when the version of the second firmware upgrade package is higher than the version of the first firmware upgrade package, firmware upgrade through the target firmware upgrade package refers to upgrading the firmware of the electronic device. When the version of the second firmware upgrade package is not higher than the version of the first firmware upgrade package, firmware upgrade through the target firmware upgrade package actually refers to restoring the firmware of the electronic device.

[0064] It is worth mentioning that the first firmware upgrade package obtained by the electronic device can also be obtained through S110-S120, that is, before the electronic device installs the first firmware upgrade package, after the electronic device installs the third firmware upgrade package, the third firmware upgrade package is stored to obtain a historical upgrade package, and the electronic device can use a historical restoration algorithm to perform a restoration operation based on the historical upgrade package and the historical differential upgrade package to obtain the first firmware upgrade package, wherein the historical differential upgrade package is obtained by performing a differential operation on the first firmware upgrade package and the third firmware upgrade package through the corresponding historical differential algorithm, the historical restoration algorithm is a restoration algorithm corresponding to the historical differential algorithm, and the determination process of the historical differential algorithm and the determination process of the historical restoration algorithm are as described above and will not be repeated.

[0065] In this embodiment, the electronic device receives a differential upgrade package sent from the cloud, and the differential upgrade package is obtained by performing a differential operation on a first firmware upgrade package and a second firmware upgrade package of different versions through a target differential algorithm; then a target restoration algorithm corresponding to the target differential algorithm is used to perform a restoration operation based on the differential upgrade package and an existing firmware upgrade package obtained after storing the first firmware upgrade package to obtain a target firmware upgrade package; and then the firmware is upgraded through the target firmware upgrade package. The cloud only needs to send the differential upgrade package, and the electronic device can obtain a target firmware upgrade package consistent with the second firmware upgrade package based on the differential upgrade package and the existing firmware upgrade package. The cloud does not need to send a complete second firmware upgrade package, which reduces the amount of data sent by the cloud, thereby greatly reducing the data transmission time between the cloud and the electronic device, thereby reducing the transmission time of the upgrade package and improving the firmware upgrade efficiency.

[0066] In one embodiment, the configuration file sent by the cloud also includes a first hash, which is obtained by performing a hash operation on the first firmware upgrade package; accordingly, step S120 includes: performing a hash operation on the existing firmware upgrade package to obtain a second hash; if the first hash is consistent with the second hash, a restoration operation is performed based on the differential upgrade package and the existing firmware upgrade package through a target restoration algorithm to determine the target firmware upgrade package.

[0067] In the present application, the hash algorithm used by the cloud to perform hash operation on the first firmware upgrade package can be MD5, SHA-1, SHA-256, SHA-3, CRC32, BLAKE2 and Si pHash, etc. The hash algorithm used to perform hash operation on the existing firmware upgrade package is consistent with the hash algorithm used by the cloud to perform hash operation on the first firmware upgrade package.

[0068] In this embodiment, the configuration file may also include a first algorithm identifier corresponding to the first hash, which is used to indicate the hash algorithm used by the cloud to perform hash operations on the first firmware upgrade package, so that the electronic device obtains the corresponding hash algorithm based on the first algorithm identifier and performs hash operations on the existing firmware upgrade package according to the obtained hash algorithm.

[0069] It is worth mentioning that if the existing firmware upgrade package is obtained by directly storing the first firmware upgrade package, the existing firmware upgrade package is directly hashed to obtain the second hash; if the existing firmware upgrade package is obtained by storing the first firmware upgrade package in the format of a drive letter device, it is necessary to take out the existing firmware upgrade package, and then convert the format of the existing firmware upgrade package to obtain a preprocessed firmware upgrade package with the same data format as the first firmware upgrade package, and then perform a hash operation on the preprocessed firmware upgrade package to obtain the second hash.

[0070] After obtaining the second hash, compare the first hash in the configuration file with the second hash to see if they are consistent. If the first hash is consistent with the second hash, it means that the existing firmware upgrade package data is complete and has not been tampered with. The target firmware upgrade package that is consistent with the second firmware upgrade package can be restored through the existing firmware upgrade package and the differential upgrade package. At this time, the step of determining the target firmware upgrade package by performing a restoration operation based on the differential upgrade package and the existing firmware upgrade package through a target restoration algorithm is executed.

[0071] If the first hash is inconsistent with the second hash, it means that the existing firmware upgrade package data is incomplete or has not been tampered with, and the target firmware upgrade package consistent with the second firmware upgrade package cannot be restored through the existing firmware upgrade package and the differential upgrade package. At this time, the existing firmware upgrade package can be deleted. At the same time, the first prompt information indicating that the existing firmware upgrade package data is incomplete or the data has been tampered with can also be output.

[0072] In this embodiment, the existing firmware upgrade package is verified, and when the verification passes (that is, the first hash and the second hash are consistent), a target restoration algorithm is used to perform a restoration operation based on the differential upgrade package and the existing firmware upgrade package to determine the target firmware upgrade package, which effectively ensures the success rate of restoring the target firmware upgrade package and avoids the situation where, when the existing firmware upgrade package fails the verification, the target restoration algorithm is still used to perform a restoration operation based on the differential upgrade package and the existing firmware upgrade package to determine the target firmware upgrade package, resulting in a restoration failure.

[0073] In one embodiment, the configuration file also includes a third hash, which is obtained by performing a hash operation on the differential upgrade package; accordingly, S120 includes: performing a hash operation on the received differential upgrade package to obtain a fourth hash; if the third hash is consistent with the fourth hash, performing a restoration operation based on the differential upgrade package and the existing firmware upgrade package through a target restoration algorithm to determine the target firmware upgrade package.

[0074] In the present application, the hash algorithm used by the cloud to perform hash operations on the differential upgrade package can be MD5, SHA-1, SHA-256, SHA-3, CRC32, BLAKE2, and Si pHash, etc. The hash algorithm used by the electronic device to perform hash operations on the received differential upgrade package is consistent with the hash algorithm used by the cloud to perform hash operations on the differential upgrade package.

[0075] In this embodiment, the configuration file may also include a second algorithm identifier corresponding to the third hash, which is used to indicate the hash algorithm used by the cloud to perform hash operations on the differential upgrade package, so that the electronic device obtains the corresponding hash algorithm based on the second algorithm identifier and performs hash operations on the received differential upgrade package according to the obtained hash algorithm.

[0076] After obtaining the fourth hash, compare the third hash in the configuration file with the fourth hash to see if they are consistent. If the third hash is consistent with the fourth hash, it means that the differential upgrade package data received by the electronic device is complete and has not been tampered with. The target firmware upgrade package that is consistent with the second firmware upgrade package can be restored through the existing firmware upgrade package and the received differential upgrade package. At this time, the step of determining the target firmware upgrade package by performing a restoration operation based on the differential upgrade package and the existing firmware upgrade package through a target restoration algorithm is executed.

[0077] If the third hash is inconsistent with the fourth hash, it means that the differential upgrade package received by the electronic device is incomplete or has not been tampered with (which may be caused by malicious deletion or tampering of data during data transmission), and the target firmware upgrade package consistent with the second firmware upgrade package cannot be restored by the existing firmware upgrade package and the received differential upgrade package. At this time, the differential upgrade package can be deleted. At the same time, a second prompt message can be output to indicate that the differential upgrade package data is incomplete or the data has been tampered with.

[0078] In this embodiment, the differential upgrade package is verified, and when the verification passes (that is, the third hash and the fourth hash are consistent), a target restoration algorithm is used to perform a restoration operation based on the differential upgrade package and the existing firmware upgrade package to determine the target firmware upgrade package, which effectively ensures the success rate of restoring the target firmware upgrade package and avoids the situation where, when the differential upgrade package verification fails, the target restoration algorithm is still used to perform a restoration operation based on the differential upgrade package and the existing firmware upgrade package to determine the target firmware upgrade package, resulting in a restoration failure.

[0079] In one embodiment, the configuration file may also include a fifth hash, which is obtained by performing a hash operation on the second firmware upgrade package; accordingly, S130 includes: performing a hash operation on the target firmware upgrade package to obtain a sixth hash; if the fifth hash is consistent with the sixth hash, the firmware upgrade is performed through the target firmware upgrade package.

[0080] In the present application, the hash algorithm used by the cloud to perform hash operation on the second firmware upgrade package can be MD5, SHA-1, SHA-256, SHA-3, CRC32, BLAKE2 and Si pHash, etc. The hash algorithm used by the electronic device to perform hash operation on the target firmware upgrade package is consistent with the hash algorithm used by the cloud to perform hash operation on the second firmware upgrade package.

[0081] In this embodiment, the configuration file may also include a third algorithm identifier corresponding to the fifth hash, which is used to indicate the hash algorithm used by the cloud to perform hash operation on the second firmware upgrade package, so that the electronic device obtains the corresponding hash algorithm based on the third algorithm identifier and performs hash operation on the target firmware upgrade package according to the obtained hash algorithm.

[0082] After obtaining the sixth hash, compare the fifth hash in the configuration file with the sixth hash to see if they are consistent. If the fifth hash is consistent with the sixth hash, it means that the target firmware upgrade package generated by the electronic device is consistent with the second firmware upgrade package, and the electronic device accurately restores the second firmware upgrade package. At this time, the firmware upgrade can be directly performed through the target firmware upgrade package to achieve the firmware upgrade of the electronic device.

[0083] If the fifth hash is inconsistent with the sixth hash, it means that the target firmware upgrade package generated by the electronic device is inconsistent with the second firmware upgrade package, and the electronic device has failed to accurately restore the second firmware upgrade package. At this time, the firmware upgrade cannot be performed through the target firmware upgrade package, and the target firmware upgrade package can be deleted. At the same time, a third prompt message indicating that the restoration of the target firmware upgrade package has failed can also be output.

[0084] In this embodiment, the target firmware upgrade package is verified, and when the verification passes (that is, the fifth hash and the sixth hash are consistent), the step of performing the firmware upgrade through the target firmware upgrade package is performed, which effectively ensures the success rate of the firmware upgrade and avoids the situation where the firmware upgrade step through the target firmware upgrade package is still executed when the target firmware upgrade package fails to be restored, resulting in an upgrade failure.

[0085] In one embodiment, before S130, the method further includes: backing up the image data of the firmware installed in the electronic device to obtain the backup image data; correspondingly, after S130, the method further includes: if the firmware upgrade through the target firmware upgrade package fails, performing image restoration processing through the backup image data.

[0086] That is to say, before performing a firmware upgrade through the target firmware upgrade package, the image data of the installed firmware is first backed up, and the backup result is used as the backup image data. In the event of a firmware upgrade failure, image restoration is performed through the backup image data to restore the firmware of the electronic device to the state before the upgrade, thereby effectively avoiding the situation where a firmware error in the electronic device and the electronic device cannot be used due to a firmware upgrade failure, and effectively ensuring that the electronic device can still be used normally when a firmware upgrade fails.

[0087] In one embodiment, the firmware upgrade process is as follows: Figure 2-Figure 3 As shown, in Figure 2 In the process, the cloud obtains a first firmware upgrade package corresponding to version v1 and a second firmware upgrade package corresponding to version v2 (wherein the first firmware upgrade package is an upgrade package corresponding to the firmware installed on the electronic device), and then performs a differential operation on the first firmware upgrade package and the second firmware upgrade package through a determined target differential algorithm to obtain a differential upgrade package; in addition, the cloud can also perform a hash operation on the first firmware upgrade package to obtain a first hash, perform a hash operation on the differential upgrade package to obtain a third hash, perform a hash operation on the second firmware upgrade package to obtain a fifth hash, and store the first hash, the third hash and the fifth hash in a configuration file. After that, the cloud can send the differential upgrade package and the configuration file to the electronic device.

[0088] like Figure 3As shown, after the electronic device receives the differential upgrade package and the configuration file, it can first calculate the third hash to determine whether the first hash is consistent with the second hash. If the first hash is inconsistent with the second hash, a first prompt message is output. If the first hash is consistent with the second hash, a fourth hash is calculated and it is determined whether the third hash is consistent with the fourth hash. If the third hash is inconsistent with the fourth hash, a second prompt message is output. If the third hash is consistent with the fourth hash, the target firmware upgrade file is restored based on the differential upgrade package, and a sixth hash is calculated. Then, it is determined whether the fifth hash is consistent with the sixth hash. If the fifth hash is inconsistent with the sixth hash, a third prompt message is output. If the fifth hash is consistent with the sixth hash, the image data of the installed firmware is backed up to obtain the backup image data.

[0089] Then, upgrade the firmware using the target firmware upgrade package.

[0090] If the firmware upgrade fails, the backup image data is used to perform image restoration processing to restore the firmware of the electronic device to the state before the upgrade. Of course, after the upgrade fails and the backup image data is used to perform image restoration processing, a fourth prompt message can also be output to prompt that the firmware upgrade has failed and the firmware has been successfully restored.
