Abstract: An over-the-air (OTA) upgrade method includes obtaining, by a server, a new version of encrypted data and an old version of encrypted data of system software applied to a mobile terminal, decrypting, by the server, the new version of encrypted data to obtain a new version of original data, decrypting, by the server, the old version of encrypted data to obtain an old version of original data, performing, by the server, differentiation on the new version of original data and the old version of original data to obtain differential data, generating, by the server, OTA data based on the differential data, and sending, by the first server, the OTA data to the mobile terminal.

Abstract: Embodiments relate to an upgrade prompt method, a terminal device, and a computer-readable storage medium. In the method, in response to the first terminal device having an upgrade version, a second terminal device and a target version corresponding to the second terminal device may be determined based on attribute information of the upgrade version, and a current version corresponding to the second terminal device may be obtained. Remark information of the second terminal device may be generated based on the target version and the current version that correspond to the second terminal device, and upgrade prompt information of the first terminal device may be generated based on the attribute information of the upgrade version and the remark information of the second terminal device, to perform an upgrade prompt operation on the first terminal device.
