In, some files run into unavoidably in the system subregions needed system are upgraded by pkg technologies, to reach quick liter
The purpose of level.When the file that have modified system subregions may result in OTA upgradings, the file changed in system subregions
Verification failure, so as to cause OTA to fail.
2nd, OTA upgradings need to remake version every time, generate corresponding OTA AKUs and issue, and can extend some tight
Anxious system bug repairing efficiency.
The content of the invention
The technical problems to be solved by the invention are：System can be entered by patch upgrading bag the invention provides one kind
Row upgrading, while the method and terminal that do not influence system OTA normally to upgrade.
In order to solve the above-mentioned technical problem, the invention provides a kind of upgrade method, comprise the following steps：
By patch upgrading bag to system upgrade before, in default backup area standby system file, to cause system in OTA
During upgrading, the system file of backup area can be verified, is upgraded with the OTA for completing system.
Present invention also offers a kind of upgrading terminals, including memory, processor and store on a memory and can locate
The computer program run on reason device, following steps are realized during the computing device described program：
By patch upgrading bag to system upgrade before, in default backup area standby system file, to cause system in OTA
During upgrading, the system file of backup area can be verified, is upgraded with the OTA for completing system.
Beneficial effects of the present invention are：
The present invention by patch upgrading bag to system upgrade before, in backup area standby system file, to cause system to need
When carrying out OTA upgradings, the system file in backup area can be read, is verified accordingly, it is normal complete to enable the system to
Into OTA upgradings, when solving system and being upgraded by patch upgrading bag, the system file of system partitioning can be modified, and led
The problem of causing OTA upgrading failures；Only upgraded if solving system simultaneously by OTA, when there is OTA upgradings each time, all needed
Version is remake, the required time is longer, it is impossible to some bug of system are repaired in time, and cause system to be deposited
In safety issue.
