Hello guys,
I have problems unlocking the bootloader in my phone. First o f all i ve recently changed motherboard i bought it from china.. the rom that it had was 5.1..... (i don't remember excactly)! I tried to downgrade to 4.5.4I so as to unlock the bootloader but i had firmware corupt message... i also tried in every rom and i got the same message.... Then i tried CONVERTER SYSTEM LOLLIPOP and filnally i got 4.5.4I... But i don't thing that is clean instal.. although i get the message firmware corupt again and i can't unlock my bootloader since the fastboot commands don't work properly.. Can you suggest soomething?
