    I am having some serious probs here. I did a ton of research and everything said it should be fine for me to buy att net10 kit and it work. I did everything it asked but It states no GSM/UMTS found do I want to go "Global". I'm rooted and unlocked. I've tried a ton of APN settings to no avail. I'm starting to think it's my baseband "CDMA_N_05.21.00RLTEDC_U_09.1D.00". If that is the case does anyone know a GSM Baseband I can flash to? Thanks for the help! :)

    btw my info is:
    System: 98.72.16.XT912.Verizon.en.US
    Model: DROID RAZR MAXX
    Android Version: 4.1.2
    Baseband Version: CDMS_N05.21.00RLTEDC_U_09.1D.00
    Webtop Version: wt-3.0.0
    Kernel Version: 3.0.8-gbacb1cf

    Many Verizon Global phones contain a lock in the software to prevent it from connecting to AT&T or T-Mobile towers. If you were to go overseas, it would probably work fine.

    OK...I did some stuff n ended up losing stock so flashed back to JB 4.1.2 and I'm rooted again.

    Problem:
    I need to unlock my boot loader again.. I know, it says once unlocked it can't go back well somehow I did lock it. Lol I tried the unlock boot loader motopocalypse. It goes to unlock then fails can't find target. Boots into ap fastboot where it still shows locked and fails. Its able to push the unlock file but once ap fastboot pops up it blocks changes to device. (Tried manual adb/fast boot won't let me in.)

    So I'm stuck there...once I get my bootloader unlocked again I should be good. I found a modem flash that supposedly fixes the gsm us lockout.

    BTW I've tried Motorola but not able to do $ fastboot OEM get_unlock_data...

    I appreciate any help y'all have to unlock my boot loader.

    I think either this might be in the wrong forum and belongs in the Razr Maxx HD(XT926) forum or I somehow missed the news of the Razr Maxx (XT912) bootloader getting unlocked. Or do you have a developer edition? Which version do you have?

    Both of those links show how to unlock the XT926. If you have the XT912, then it won't work because the 912 uses the omap processor that is locked up not just software wise, but also hardware wise. The 926 uses a snapdragon processor that isn't locked up as tight

    Dang...I guess I got lucky the first time it unlocked me... sux I had to mess it up. Pretty much what I want, n I guess the world wants, is to unlock and flash new radio for us gsm service. Oh well doesn't look promising for us xt912'ers

    Dead thread til boot loader is unlocked by those devs or Motorola opens it up for us. *Cross fingers*
