I've had this problem before and don't remember how I fixed it, pretty sure I just kept turning it on and eventually it just gave up trying to update. Phone shows the following: AP Fastboot Flash Mode (S) 10.9B(*) (sha-1e9f557 , 2013-09-25 16:26:59) eMMC Info: Size 16GB Device is LOCKED, Status Code: 0 Battery Low Transfer Mode: USB Connected Fastboot Reason: Flash Failure Phone Info: Model: Droid Razr HD Android version 4.1.2 Used to be rooted What keeps happening is my phone is trying to update to 4.4.2 and I didn't want it to happen, but by accident I clicked "Install Now" instead of later... It's been 2 days, I can't get it out of wanting to update. So every time I turn it on, it'll boot up but once I'm at the home menu within 20 seconds or less it'll be turning the power off again. This happens every time. I can't even charge it because every time I leave it on the charger it just tanks... Say I restart this thing 10 times, suddenly I'll be at 35% battery life, I stop for 10 seconds because I screwed up getting the boot menu, now I'm down to 5%. I know my charging cable works, the phone just won't hold a charge and it won't stay on... No I can't do a factory restore, I've tried several times. It'll either boot the phone up and die again, OR it'll just do nothing.. Someone please help..
