The invention provides an upgrade processing method and device and a storage medium. For the terminal equipment, before a target application is operated, if it is determined that the target application is abnormally closed in the last upgrade process, the terminal equipment obtains state information of the target application when the target application is abnormally closed, and an upgrade repair process corresponding to the state information can be executed according to a preset upgrade repair process. Therefore, the problem that the application cannot be used due to the upgrading exception is avoided, and the processing capacity of the equipment to the upgrading exception condition is improved. For the server, at least one processing function of the device can be automatically optimized based on the user feedback information from the terminal device and the preset training algorithm, the file upgrade package for the feedback information is generated, the file upgrade package comprises the upgrade file of the at least one processing function, and compared with an existing upgrade package, the file upgrade package has the advantage of being small in size. Only the upgrade file with the specific function is updated, so that the release period is greatly shortened, and rapid repair of the equipment function is realized.
