I cant unlock my phone's bootloader.I have unlocked my bootloader before, I tried installing custom roms but something went wrong and I flashed the stock firmware.
After I flashed the stock firmware, everything seems to be fine but then when I try to unlock again, it doesnt work and gives me this error:
An unknown error occurs, which may be a network connection issue. Please try again later.

  • Hi all

    Can you help me confirm that phone is up to date? The latest version is WW-15.02.1810.380
    Please try clearing app data of the unlock tool, and then try changing a network environment and try again.
    If you still can not unlock, please provide your phone serial number to be via private message, Thank you
