[Q] Problems charging/holding a charge/can't boot

Having massive issues right now. Last night I left my phone plugged in AC to charge and ran a sleep tracker app. Woke up this morning and found the phone dead. I tried unplugging and plugging again multiple times and managed to get the Red LED blinking then it went steady indicating it was charging. Turned the phone on but as if it wasn't charging anymore, it powered off within minutes. I managed to get recovery running and factory reset (running CM10). Same issue still there. I even tried leaving the phone in hboot and recovery to charge but after 10 mins the battery went flat again. Now I've just left the phone off and plugged into AC. The blinking LED came on again then went steady - but after 15 mins the LED light disappears. I just left it like that, now the phone tries to boot up but gets stuck at HTC logo. Also it is incredibly hot.
Any ideas? Really need help here.
Additional info, installed NFS: Most Wanted yesterday, tried playing but phone really overheated big time. Could that have cause the motherboard to fry? Just seems odd though cause it boots up fine, just won't stay on - can't even get past the initial setup wizard.
Also I would take it back to Vodafone AU but since I can't get the phone up long enough to restore to stock, they might find out I've rooted and thus voiding my warranty.

I had the same problem. I installed NFS MW and it drained my battery like help and when i tried recharging it it wouldnt charge
at all. Even when i pluged the phone on it wouldnt charge. Tried a different cable. For all it could be a adapter/cable problem.
That was what it was for me. I tried a different charger and it worked. If you are using a different charger, use something with 1A output.

If the led is blinking, it means that the battery is verryy low.
once your phone turns on, turn the airplane mode ON and display OFF and wait a few minutes before using the phone.

no luck

Yea, I tried using a different cable, even tried using my old iPod USB to wall adapter. No luck there, but I think I'm on to something now. Thanks anyway

getting there

Hey, yea I figured that much from searching around. Too bad it's such a big flaw. I couldn't sustain a charge at all when I was still on CM10. Couldn't even finish booting up and it would just die. Voltage was super low was my guess. Tried using the fastboot charging script (http://forum.xda-developers.com/showthread.php?t=1658084&page=5) and managed to get battery up enough to flash stock boot.img, did a nandroid restore to Stock ROM then flashed stock recovery. Seems to be stable now, in airplane mode and display off. Started up phone at 4% and now it's at 6% so fingers crossed :fingers-crossed: Thanks for the reply though - needing all the tips I can get!

[Q] Fried battery?

So occasionally if I'm up too late, I don't hear my alarm (on phone). Well, I had noticed recently it got super warm to the touch if I overslept a bit, I think because it just buzzes constantly while plugged into the wall.
Anyway, it won't turn out now without direct power plugged in. Tried reformatting, wiping cache, everything.. I can get it plugged into the pc and booted up but as soon as I try to select media storage, it fails. Won't turn back on now even with it plugged in.
Any suggestions, did my battery just croak?
TYIA.

that's what happens if you charge it overnight

For real? Man, I'll be honest.. I had to break my flashing addiction, so I intentionally got an older Nex, so I could root, and leave it the F alone.. Haven't flashed a ROM since I owned it (bought it unlocked like 12 months ago), couldn't even tell you what ROM is/was on it..
Since when is it a bad thing to charge overnight? I adopted that habit when I went android. :/

well some phones don't have any problems with ovecharging but its not recommended nevertheless
heard some batteries were F***** up from overchargind

Same exact thing happened to me...thought the phone was fried. I replaced the battery as a last ditch effort and she lit up like a Christmas tree. And as for that last response, I leave mine on the charger all night literally every night without any negative issues. You cannot overcharge the battery on an android phone. They have protective charging circuits, just like laptops.

I'm hoping it's only that but wouldn't it fire up with wall charge? It freeze on the Google loading screen.. have a feeling it's cause I wiped it and maybe it didn't finish.
EDIT: Okay, I obviously was a bit messed up earlier.. I factory wiped it, including the OS.. how can I jump an OS onto this thing if it won't boot without charge?

Okay, well the symptoms sound exactly the same as when I fried my battery. At first, mine would only boot with a wall charge, but then it stopped doing even that. The only thing I could get into was the boot loader. I'd try a new battery before worrying too much. In the meantime, however, can you see if the phone is being recognized by a Windows PC, or if you can get the bootloader?If it is bricked, there is a bit of software called OMAPFlash that i used once that can completely reset the phone's programming.

If you just wiped the OS from recovery you should still be able to boot into fastboot. Are you able to boot into fastboot (power+volume up+volume down)? If so then it is not hard to fix.
If you can't boot into fastboot, try:
1) Without battery, plugged into wall (try a different charger)
2) Without battery, plugged into computer
3) With a different USB cable.
Does it vibrate when turning on? And does it go into fastboot?

When I plug it in, the initial charging indicator comes up (Battery with lightning bolt), but won't otherwise turn on via holding power.. or get into fastboot at all. If I plug it into my pc, it initially shows the power indicator again but same deal. Interestingly enough tho, my pc makes the sounds it makes when it's syncing or installing usb drivers for something.. except it starts, then stops, then continues.. it's non-stop trying to sync but nothing is happening, it's almost as if it's getting either a partial charge/connection and then it stops. What I thought before was a battery I'm thinking is worse cause I can't get the thing on at all now. :/ Might be time to hit Verizon today..

It was the battery but now I have no OS on the phone.. UGH. I can't get it into storage mode to pull a new ROM over from PC to flash. Anyone know how to force a ROM over via adb?

Boot into a custom recovery, adb will work there.

HTC One M8 Totally Dead (No Access to Boot Menu)

Hello everyone,
Thanks for always helping in times of trouble.
I was using my HTC one m8 normally, playing with facebook. The battery was on 82%. Suddenly the screen frooze then the whole phone went dead completely. Not even a screen backlight. I tried to power it up. It didn't work. It had original ROM, with no modifications whatsoever.
Here is what I did so far, without any results.
- Charge it for few days with original charger and cable directly from the wall. No sign of life. No charging flashing light.
- Charge it with another cable. Nothing.
- Tried to access the boot menu to wipe everything clean. Pressed power+volume down. Nothing. Dead Screen.
- Pressed power +volume up. Nothing. Dead Screen.
Pressed power + both volume buttons. Nothing. Dead Screen.
- Connect it to the computer with updated HTC Suite. The computer said no phone connected.
I using a crappy old iphone now, but would love to get this HTC back to life. Any past experience with similar situation?
Any tips to resuscitate the dead phone?
Thanks a lot for your help.

In some "stuck" or powered off conditions, you may need to hold the button combos for a minute or so, before it actually reboots. So make sure you are holding them long enough.
But the fact there isn't even a charge LED, is concerning. Even in brick conditions, you should get at least an orange/red LED (maybe blinking? Can't remember). Makes me think the battery is bad.
Also play around with the button combos with the charger connected. I've seen a couple folks have luck with this, when nothing else seemed to work.
Additionally, the phone won't connect to PC when powered down; even on a working phone. You at least need to get to a bootloader screen to connect to a PC in any way.

I tried to do as instructed but it didn't work. I held the buttons on different combinations for at least two minutes but the phone stayed dead.
The only changed I noticed is one point I saw a very weak charging flash then it quickly disappeared and never came up again even when I repeated the process. Does this say anything?

Hard to know if this means anything specific. The symptoms don't look good. Might be bad battery, or other hardware failure.

Random reboot hard bricked my Robin

May be unrelated but updated to the latest nightly of Lineage, ran into the camera issues and got some random reboots. Sent an email, and then put it in my pocket, pulled it out a few minutes later and it wouldn't turn on. Have done the hold down power and volume down button to no avail. Used the USB cable to hook it to the laptop, see it in QDLoader 9008 mode. If I hold down the power button and the volume down button I can see it disconnect and reconnect but it never turns on or shows anything on the screen.
Spent a few hours googling it and looks like you need some hardware specific files to the QFIL method, which I can't find. So is this device toast? Was really enjoying the device and so sad that it died after only using it for about 1.5 months.

**UPDATE**
So the leave it plugged in to the laptop overnight trick didn't work. So I took the phone a part, when it's in this mode it seems like there is is still power to system. I left it open until the battery died, and the regulation circuit cut power. Then plugged it in the laptop(although a charger would probably work). Let it charge for 10min and it came back. Seems like it get stuck somewhere in the boot and needs to be reset, but without a removable battery you can't cut power. So if anyone runs across.this, leave it disconnected overnight(or maybe longer) until what ever state it is in kills the battery. Then plug it in and it may come back. My booted after being plugged in for 10min and turning it on using the power button

So I have the same problem with my device and am thinking about doing the same thing. What tools do I need in order to perform this?

I also have the same problem, is there any help?

So this worked for your hard bricked phone? And you had no more issues after?

Help! Pixel 2 XL Won't Turn On

Hi everyone,
I'm hoping for some help with my Pixel. I was charging my Pixel overnight (though it was at ~65% battery) on a battery pack a couple nights ago, and when I woke up the phone was turned off. Nothing I can do now will get it to turn back on. I've tried multiple chargers (including the OEM), leaving it plugged in for a long time and then trying to turn it on, turning it on while holding power + volume down, etc. My PC will make a sound when I plug it in, like it recognizes a new USB device, but then it won't show up as a device.
Any ideas on what to do about this or what could be causing this issue? Currently phoneless so any and all help is hugely appreciated!

Stock or rooted? Have you tried different cables? Can you enter bootloader mode?

Stock. I've tried two different cables, three different chargers. Can't get it to boot in any way.

Holy crap! Almost sounds like your mother board went kaput! If you can't get into recovery or bootloader mode to do a factory reset, then about the only option as I see it is RMA. You certainly have grounds for it!

Something similar happened to me couple of month ago. The phone was on the charger and when I wanted to check it I noticed it was switched off. I could not switch it back on, tried to put it on different chargers, pressing different button combinations along with the power button, nothing helped. I then plugged the phone in to one of the usb 2 ports in the pc, used an Anker usb A to usb C cable. I could hear the sound the pc recognized it, then pressed volume up, volume down and power button for about 15-20 seconds. The phone switched back on... Since then (touch wood) hasn't happened again... Worth giving a try...

Me too! Kept trying all methods to start it. Nuthin.......
Then left it connected to the computer for awhile: a little later, magically started the same method mentioned here.

I had my motherboard and battery replaced due to the same issues. The charging port seems to be an issues too.

Did you have Google replace them under warranty? What was that process like?

Same thing happened to me once. I was sh**ING bricks because I bought my phone from eBay. Reached out to Google Support and they gave me similar instructions. I had to hold volume up and power for about 20 seconds and it finally booted.
