  1. bonjour, j’ai le message d’erreur “error: 0x2000, MP26010v_00_1214.kdz file does NOT support “REFURBISH” process”, que doit-je faire ? merci

  2. so i got the firmware in and it still asks for a secure startup password so what password is used? i tired every password i use and now i’m at 13 of 30 so is there a backdoor password? i guess if i make it to 0 the phone is useless and i might as well sell it for parts.

  3. I did extracted the zip file and then the firmware disappeared on me. Just turn off or disable any antivirus you have on your windows and you will be fine.
