Hi, recently I bought an atrix 4g with the broken glass. I replaced it, unlock the bootloader and flash the cm10 in it. I bought the code to unlock and when inserted it says that failed. Could this happend because the rom is not the original? I made a back up but the micro sd card stopped working and now I don't have any way to go back to stock. I'm not sure but I tink that the network lock is t-mobile uk.. Can I found out what carrier is the phone locked? Can I download the stock rom or OTA? Thanks to all
