The invention discloses a device for recovering a mobile terminal download access, which comprises a capacitor and a switch circuit. One end of the capacitor is connected with a pin of a master chip of a mobile terminal, and the other end of the capacitor is connected with the switch circuit. The switch circuit is connected in series between the master chip of the mobile terminal and a download interface. By the invention, the legal download of downloading updated software legally is realized, user experience is promoted, and a hacker is effectively prevented from illegally reading and downloading data of the mobile terminal, so the network locking is better realized.
Description
A device for recovering download path of mobile terminal technical field The invention relates to security technology in the field of communication, in particular to a device for restoring the download path of a mobile terminal. Background technique At present, the operation mode of global mobile operators is: provide users with mobile terminals such as mobile phones free of charge, users must abide by the agreement, and must use the operator's network within the specified time. In order to prevent the users of operator A from illegally entering the network of operator B within the specified time, the mobile terminal provided by the manufacturer to the operator must be processed by the network locking technology, that is, a mobile terminal can only use a fixed operator network provided. In the initial network lock technology, the operator adopted the machine-card integrated mode, such as: China Unicom uses the code division multiple access (CDMA, CodeDivisionMultipleAcce...
