Bootloader code: NNEV1GZ1NXH75SDO


But seems it didn't work: it says
fastboot oem unlock NNEV1GZ1NXH75SDO

...
FAILED (remote: check password failed!)


My username is bl14381. I have another phone I want to unlock so I'd want to ask for a refund in credits. thanks.

Please provide more details as it is unlikely that code read directly from mobile does not fit it. Paste here detect info of this mobile device. and Provide screenshot of cmd/adb with code entry.

Nevermind, it was a issue about how I was pasting the key.

I ended finding it today by using PowerShell instead of cmd.

Thanks!
