After flashing CM10, my AHD does not charge correctly when it is powered off. If it has enough power to run the screen (i.e. no green light) it simply displays the unlocked bootloader splash. I've left it overnight like that, it doesn't change. Any suggestions?

My phone (which is currently running Incubus26Jc's Android 2.2 FroYo RLS10 NAND) rebooted at around 12:30 AM. I noticed that it reboots, randomly, about twice a day. Not sure of the cause, haven't looked in to it, but normally it comes back to the desktop, like a fresh boot of the phone. So I thought nothing of it.
Last night, however, during the reboot, SOMETHING happened, and it seemed to have gotten stuck in an infinite loop. It would show the boot animation for a while, then lose power... then it would notice the power cable was plugged in, and try to automatically boot up.
If you notice, plugging the power cable in forces the phone to boot all the way into the Android OS. There seems to be no "charge while off" feature, at least for me.
Anyway, this endless loop caused the phone to reboot over and over and over, until the point where the battery was so far drained, that this "hand off" between the boot screen and the actual OS (somewhere during the boot animation) where the phone had to run on battery for a split second, was long enough to cause the phone to power off completely.
I couldn't flash back to Windows (I thought) because the phone didn't have enough of a charge to stay in bootloader mode while flashing the phone. Which was mostly true.
FYI (how I fixed my problem): should something similar happen to you, put the phone in true BOOTLOADER mode (hold the camera button when you press the power button, see the colored bars across the screen), even though the indicator doesn't light up, the phone DOES charge when in this mode and plugged in to a wall charger (and probably while plugged in to USB).
As far as I know, you are required to maintain a certain level of charge to run the RUU because the USB cable cannot charge the phone WHILE FLASHING, but while waiting in bootloader mode, the battery will charge. I was able to let the phone sit at the bootloader for about an hour then started up my phone and had over 70% charge according to Android. Working again!
thank for the 411. i had a similar issue with rls10. went to 10.5 and rls11 and flashed a new kernel, no further issue since
I still didn't get my OTA in Croatia so I decided to try this. I came across an issue which wasn't present in official 4.1.2. and maybe someone had (and still has) it as well. I'm posting this here so that it's easier to find if anyone has this issue and wants to fix it.
I have installed 4.3 on my Xperia T with Locked Bootloader and everything worked fine. However, I have come across a issue and managed to solve it as well. Here's what happened and how I solved it, maybe it helps someone with same problem.
Today my battery drained to 0% and the phone shut down. Now when I plug it in to wall socket to charge, red LED goes on and it turns the phone on. Once Android boots I can see 0% in status bar and it starts shutting down again. Then it boots up again and loops like that. I remember that on 4.1.2. there would be a battery icon when it was completely empty and it wouldn't boot the system. Now it just loops. This didn't happen on official 4.1.2.
I have Googled for solutions and have tried this.
"1. Press and hold down the power key on the right side of the phone. If the battery status LED flashes red, try plugging the charger into the phone at the same time as you are pressing and holding in the power key.
When plugging the charger into the phone there is a risk that nothing happens – no red battery status LED as indication of charging, or nothing appearing on the screen.
If the charging doesn’t start, follow the instructions under To let the charger be plugged in for 24 hours.
2. If the charging starts, keep charging the phone until it’s fully charged. Indication of charging is that the battery status LED lights up in red, or that the SONY symbol appears on the screen and then the LED lights up."
Problem was that when I left it to charge (screen off, LED red) it would start booting again after a few minutes. When it started to boot, I would press volume up + power key to shut it down and keep charging. I had to do this many times (10 to 15) and it was very frustrating but it worked in the end. I decided to let it boot and voilà! it showed 1% battery and didn't start shutting down. Now it's charged to 2% and keeps on charging.
The lesson - don't EVER let your Xperia discharge below 1%, you'll have a world of problems.
I have the exact same problem, except that it doesn't even charge when my screen is off.
Great find! I used a separate way to get it to charge but I can assure you it gave me a world of pain! Thank you for sharing
What about the Xposed module DisableCriticalBatteryShutdown?
If or devices were no longer turning off again after booting when battery is 0%, the problem would be fixed, right?

I have a C6003 running 4.4 Stock with an unlocked BL and am rooted. The phone screen is cracked at the top third (not smashed, just 2 long cracks) and that third of the screen does not receive touch input, but still displays. Anyway, the phone is currently out of battery, when I try to power it on, I get either a flash of the Sony logo then 3 blinks of the red LED or just straight to the LED, which is normal. I plug it in to charge (tried several USB cable / wall plug combos, up to 2.1A etc.) and the red LED glows solid as it should. Even hours later it still will not power on and gives me the blinking LEDs...It was charging for a total of at least 7 hours and is still not turning on. I have had several battery issues recently but this is the most serious. I am sending my phone in for repair under insurance for the screen but need to back it up first! Any help is appreciated.
EDIT: Quick edit to add the fact that this same issue occurred yesterday as well but it eventually powered on with 15% battery, I used it and it would not charge and so that is why it is run down again. Even when powered on it would not charge, the LED did light and it charged for 5 seconds each time the cable was inserted, but after the 5 the LED would stop and it would stop charging. The phone knew the cable was there though as when it was inserted Stamina mode was disabled (as it should) even though it was not charging?

I was talking on the phone on my way home. The battery lasted all the ride home, that's good, but it died on me just as I got home. So I plug it to the charger and it turns on like normal on the charging screen with the horizontal color battery animation, and the orange charging light pulses. Then it changes to the other battery animation, the all white vertical one, and the orange light stays solid, like normal. The issue is, the phone doesn't even last a second charging, the orange light turns off, and the phone reboots, only to repeat what I just wrote... So I tried to turn it on as soon as the second battery animation comes up, then the orange light goes on solid for less than a second, and it manages to turn on. It goes through the splash screen and the boot animation, no problem. But as the boot anim fades and its supposed to finish booting and start charging again, neither does it finish booting nor does it start charging... The orange light starts to pulse twice quickly, as if telling me it's not charging, and then shuts down... The phone is rooted but running stock everything, AT&T 4.4.2... Any ideas???? After some attempts, I'm able to get it as far as into recovery, but I really don't know what to try as this definitely doesn't seem like a Rom error or anything that flashing or RUU would fix????
I looked in the previous threads about non-booting but no one I could find had my issue. Bought the Nook HD+ about 4 months ago and rooted it and installed Android (not sure which version but cm11). Out of the blue, last week I pulled it out of my bag and the battery % was flipping between 1% and 31%, so I put some stuff on it via USB and then shut it down to charge. I plugged it in overnight and tried turning it on in the morning. All I was getting was the low battery picture, so I kept trying to charge it, but it wasn't charging, the power light would go to orange when I plugged it in, thena fter 3-5 seconds it would flip green and then turn off and retry. My assumption is the battery is dead, but it could be a corrupted OS now as I got it to charge long enough to get to the CM11 boot menu. But I even went out and bought a new charger and converter to rule that out and it still is stuck in the same boot sequence. I obviously can NOT charge this thing while it is off because of it's reboot loop, it can't charge. I'm not quite sure what is going on or whether it is a battery or boot issue but after I leave it for a big it freezes on the cyan picture (which is frozen on some scrambled version of it) until I turn it off.
I can't power it on enough to charge it to rule out the battery, I tried holding the power and n button for 3 seconds, letting go of the power, and then pressing it again to get into the recovery menu, but that isn't working either. And I prepared another SD card for a second flash for a corrupted OS and that didn't seem to work either.
I'm stuck here and I'm not sure what to do now to get it running again. I don't care about the data on my tablet at the moment.
Try plugging it into a PC USB port over night.

That's what I did that got it charged enough to get to try to boot, where it now shuts down. But now as it tries to boot it reboots, maybe from too much power consumption? I only had it plugged in for half hour or hour before that got it charged to the point where it boots to the logo screen. I have a feeling it is not charging because every reboot the light turns off (orange light stays on for like 5 seconds)
I will plug it in to my PC and charge it overnight and let you know what happens. It's interesting, I plug it in now and the orange charge light comes on, shows the Nook screen, then shows the low battery screen and shuts off, then the orange light turns off, but it remains plugged in... not sure if it is still charging but as I said, I will leave it overnight and see what that gets me.
No success. I can turn it on and the charging lights turns on for 5 seconds and shows the nook screen, then goes black and shows the low battery screen, then immediately shuts off and the charging light turns off and it no longer charges.
Any other suggestions? I can't seem to do anything with the Nook now.
