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.
