The program does not unlock the bootloader, writes (An unknown error occurs, which may be a network connection issue. please wait and try again later)
I have tried:
Reboot phone
Tried the next day
Chance network
Facroty reset
Update firmware
USB debugging enable
What am I to do?

  • Hi virus42425,

    Good day.
    Could you help me to check your CPU sku and firmware version again?
    (1.) Unlock Device App version
    (2.) Firmware version / CPU sku
    (3.) Please show me this error screenshot
    (4.) Please kindly texted me your serial number for a check. (settings> system > about phone > status > serial number)

    Thank you.
