    Does anyone know if/how the phone can charge in fastboot?

    I had 40% when I tried to flash back to stock and during the process the program stopped because the phone doesn't have enough charge. It doesn't seem like the phone charges when its off or on the fastboot screen.

    any help here?

    It does not charge in fastboot, but should charge when off.

    Correct. You should have a least 60% charge before starting Fastboot. Better to have 75%.

    So when I plug it in, the fastboot screen pops up, just press the power button to shut the phone off and wait about an hour for it to charge up?

    Well.. I suppose its better than stripping a usb cable and prying off the back of my phone like I read on some other forums. Your sure this will charge the battery? I get the feeling when fastboot comes back up its still going to say low power..

    I've heard what he's saying told by others but I can't confirm it's accurate. Can you power the phone off completely before plugging the phone in, or is that what you did? You may be forced to create the custom cable mentoned.

    I have to do the cable method, which I really have no idea how to do, so I am probably going to pay an $80 restocking fee to get another razr and just not root these god damned phones anymore.

    Well i remember tht when i unplugged the cable from the phone it would say low battery i remember instead of unplugging it, i just directly took the ac adapter off and immediately inserted it into the laptop as fast as i could and it worked...it wont hurt to try it out :/

    I had the same problem. I turned off the phone then plugged it in an AC outlet for 30 min. Then I was able to get in fastboot and go back to stock

    Good luck x25064, hope you don't have to "reengineer" a charging cable.

    FOR ALL USERS WHO ROOT: (x25064, the following recommendation to other users who have root is not intended to make light of your trouble...may be a lesson learned for others...good luck man). NEVER ROOT, PERFORM AN UPDATE, FLASH A ROM, FLASH A BACKUP OR PERFORM A SIMILAR OPERATION ON YOUR PHONE WITH LESS THAN 80% CHARGE ON YOUR PHONE. You may get away with it occasionally, but sooner or later you'll experience a problem.

    I had to splice the cable. Luckily I had a factory cable from my D1 so it wasn't as bad as I imagined. Taking off the back of the phone was also very simple. I don't understand why they didn't make it removeable to begin with. The back of the phone removed very simillarly to a HTC, minus the sticky bit.

    Anyway, there has to be a better way to fix this issue, either a failsafe in adb or a way to charge the phone without firmware cause this was totally ridiculous. Yeah, it was my fault, but ripping apart a usb cable just to power the damn phone .. really?

    Glad things worked out for you. I agree, there has to be a better way.
