    What about if my firmware was N900AUCUCNC2 .. Can I use N900AUCUBMJ5 to recovery my phone ???

    • As long as the Device is same, however, I won’t recommend it,cause it might Start Problems with the Device signals, you can find N900AUCUCNC2 Firmware on SamMobile..

  • This shouldn’t be happening, try any other version, like you have tried the MI9….
