The difference between the official solution of Japanese iphone6plus and the black solution.

Unlocking method 1: brush the machine and re-enter the ROM. It can be understood by ipe from the professional point of view of brush lovers, and it can be considered as the operation of erasing mobile phone data. Regarding what wipe means, the professional answer is: wipe means restoring factory settings, including deleting all contacts, text messages and installed software. Call it a hard start and restore the factory settings. Note: After erasing, you need to redo the app2sd and root permissions. And the important partition steps of app2sd have to be repeated. Double erasure means clearing cache and memory data. Unlocking method 3: Use adb to delete the forgotten screen lock password. Operating Steps: Connect the mobile phone to the computer, and do it in charging mode without opening the data connection. After unzipping adb.zip on the computer, put the adb file in the root directory of the computer C drive. Continue to delete *. Key file. Enter adb to restart or manually restart the phone to take effect.
