The phone is 100% working now but i want to install it a custom rom because doubt in SIM tray failure. If i put the stock ROM and the voice calls are still in gray(inactive) then i will know that it`s really the SIM tray.
I connect the Phone without battery to Windows PC and it does only auto refresh.
Thanks in advance
