So one morning I woke up and saw phone keeps rebooting(bootloop).I had breakfast then came back to pick it up,and i connected it to charger and phone was totaly dead.I tryed other cables but still same result.Only way to power it on is when I use original cable and connect it to charger/pc.Then red led turns on and display showing low battery,and led keeps blinking.Sometimes it can boot into system and works for few minutes and shuts off cuz 0%.I changed battery but everything is same,I also can go into TWRP.
**I TRIED EDL MODE/two pins or whatever and my PC is not showing Qualcom driver or anything else in relation with phone
i had same issue before, i simply just buy new cable and it working again!!
PS. Before i buy new cable i already had 3 type-c cable bot non of them working
I had the same issue an hour ago. My MI5 had ~25% charge left when I saw it shutting off, maybe I unknowingly did it. Then I decided to leave the phone in TWRP at night but in the morning it appeared to be dead. The red LED blinked only when I pressed the buttons, no turning on, fastboot or booting into TWRP was possible. When I plugged it into the charger an empty battery icon appeared with the red LED blinking continuously. After some time a new animated battery icon appeared, in the still turned off state, but this time showing the exact charge percentage (2%). It went to 3% and I turned it on with the power button.
Should be a faulty battery which needs to be replaced!

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 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.
Hi, first of all sorry for my bad english.
I just bought Motorola Moto G 2 and i tried to start it - white LED lights and the device isn't starting, i thought that its normal that the battery isnt charged because its new phone. I plugged charger and it showed me that battery is about 50% charged, and when the charger is plugged phone starts and works normally, when i unplug the charger phone still works (havent checked for longer time but didnt immediatly turn off, just worked), but when i turn phone off and try to turn it on again LED lights like its discharged.
I tried charging to 100% and unplugging, doing reset but still the same. Only works when starting with charger plugged. What should I do? Is there any solution?

If the led is lighting up for just a moment, you didn't hold the power button long enough. If device is not starting up even after pressing power 5-10 sec.... customer service
Hi,
After many years of enjoying this magnificent phone the disaster came.
The phone discharged overnight and switched off. In the morning I had to send some texts, so plugged the wall charger into USB socked (a weak one ~500mA), after few moments a charging icon appeared and stated that battery has 1%. Ok, I really had to send those messages: I've pressed the power button and phone started to boot.
Sony logo: OK, purple wave, OK...
After 10-20 seconds it suddenly switched of, red LED started to blink.
I thought: OK, system startup needs a lot of power, maybe a charger is too week to keep up.
So I left phone for few more minutes to charge, but without success.
That was the last time I saw screen was on.
Phone is a C6903, running on a stock, rooted 14.6.A.1.236 with the recent XZRecovery.
Bootloader has been unlocked.
For the moment I've tried everything but opening back and doing the testport-trick.
When I connect the power only red led blinks (I left the phone charging overnight, no change).
When I try to enter flash mode: nothing happens but red blinking light.
When I try to start phone nothing happens at all.
But there is still hope:
I connected the phone to 2A charger using a magnetic cable.
Then I've connected normal USB cable to my PC, strange thing started to happen:
When I pressed volume Up (even after few minutes of connecting power+usb) the phone suddenly jumped to fastboot mode (blue led, it was discovered by PC, fastboot terminal was functional)
When I press power button, phone vibrates for a second, then the led pattern changes to: 1s red followed by 0.1s green, then long red, then it repeats...
I'm still unable to enter any recovery nor flashmode...
I'd really appreciate any help, have you got any ideas left how can I revive my phone?

Hi, this just happened to me, my phone has been dead for over 4 weeks with just the red led blinking. i tried the test point thing with no success at that point I gave up but last week i decided to get a new genuine battery and it worked it booted up. Your battery is just completely dead thats why it won't boot up!

Thanks for the info! I've ordered a replacement battery already.
I'll open my phone today and measure all voltages. I'll keep you updated.
Good luck

Yup! That was it (at least I think so, I don't have new battery yet)
The Al part of positive battery terminal was broken: I have no idea why, maybe because of age, oxidation and high currents that were drained from this LiPo cell...
Anyway I've managed to temporarily join two broken Al parts, kernel and recovery booted successfully.
Now I need to wait for a replacement battery.
Phone is alive again, thanks tilakpatel for help!
But the magnetic cable trick might be useful in other hardbrick cases: just connect magnetic charger, connect normal USB cable to PC and hold volUp. Phone should be able to enter fastboot even with completely drained battery...
