Just wanted to share a good procedure to relock the bootloader, in case you are not satisfied with the limitations of the custom ROMs (like banking apps refusing to work) and want to go back to stock ROM.


It worked for me, though I had to follow a little bit weird sequence (described in the link above on page 2)

  • Hi friends

    Here to provide a soft reminder to everyone who attempts at unlocking/locking the device: Even you lock back your device in device-side successfully, the server-side will remain an unlocked records. It means that once your device is unlocked, even you lock back your device, the device will not be regarded as Original Product permanently.
