I have a rooted stock phone that stopped working for no apparent reason (no new ROM flashed, no configuration change). It starts, shows the Samsung logo, and immediately reboots. I tried to put it in download mode, when i hold the 3 keys I see the download logo showing up, but it reboots after a few seconds anyway. after a while it will start looping through the battery charge screen (which shows the battery as empty). I tried 2 different batteries with no change. Any idea how to get something working again?
That almost sounds like some sort of power issue. Have you left it sit turned off until the battery was full?
Yes, I left it overnight and it just keeps flashing the battery screen and then resets. I also have an external charger and used it to charge the battery, so it's not an issue with the battery actually being empty.
Have you been able to get the phone into download mode previously?
Have you have dealt with a boot loop and performed an Odin recovery previously? If not, remember it can take a few tries to get download mode to pop up.
If you can't get Odin to go, you might try flashing with Kies.
I am wondering if your phone met with some kind of disaster when you weren't around (trauma or liquid).

This sounds almost exactly like the problem I had with my Sidekick. In my case, it turned out to be a bad battery and a loose ribbon cable on the motherboard. I'd check those two things.
This happened to me as well, and the three-button method to get into download mode wasn't working. For some odd reason, for me to get into download mode all I have to do is hold down the power button + track pad, and it goes right into download mode... Maybe slightly different model?
Try that - power button + trackpad
Bootloops.
Not a guaranteed fix by any means but for troubleshooting purposes you may want to consider making a USB JIG. It will most definitely help you figure out just how serious the problem is and if it IS software related with a way to get it working again you will need the JIG anyway so its worth a shot. If nothing else you learn a new skill and you're the proud owner of an incredibly useful tool that you can say you made yourself. good luck!
I know this post is kind of old, but it just happened to me last week (same circumstance, a rooted phone, but stock). I ended up just pulling the battery out and pressing the power button a couple times to hopefully drian it and letting it sit for 15 minutes, and then I put the battery back in and it worked again. I now have another rom flashed on it, I hate stock.
I know this forum is ancient, but I'm working on an E-Bay phone with this exact issue. I found the following thread the most useful and informative on the problem:
http://forum.xda-developers.com/showthread.php?t=1996709
Hopefully this helps other.
what i did was hold the power volume and button between the menu n back with the left hand YES HOLD IT UNTILL THE PIT IS UPLOADED. then u can let go then slide in the vattery with the right.while checking off the flash bootloarders on the heimdall with it fixing my phone XD
I had this happen, I dissassembled the phone, and used an alcohol pad to clean the power button area, and manipulated the button a lot, let it dry, reassembled...it still bootlooped.
BELOW IS RISKY BUT WORKED FOR ME
So while the back cover was off (exposing the cicuit board but everything still connected) I inserted the battery and watched it boot loop...during this, I used a flathead screw driver to "short" the power button pins...this let it boot fully, and it has been fine since.
i smacked the phones power button a few times and it worked
Hi guys,
I just recently flashed my phone to the Romulus rom, and its been going great. There have been a few hiccups but nothing too big, except for 2 things:
1. Whenever the phone is plugged in, the lockscreen becomes unresponsive. When i try putting in my unlock pattern, it only allows about 2 dots max before it thinks i have lifted my finger of the screen. To fully enter the pattern i have to unplug it, enter the pattern then reconnect the charger. Anyone else had this, or know of a fix?
2. This is the major one. For some reason, when my phone turns off due to low battery, the phone just wont come on, no matter how much i charge it. It gets stuck in a bootloop at the moto logo. Its happened twice now, the first time i somehow got it working by using the charger to turn it on, then unplugging and pressing the power button immediately at the logo. However yesterday this isnt working. When i do that, at times it boots up, but then when it gets to the lock screen it tells me to connect the charger, then shuts down again. The battery icon is red with an X accros the symbol. Does this mean that its not detecting the battery? How would i fix this?
Cheers for your help

First off mate, all questions go in our Q&A Section, so just keep that in mind going forward.
Now, your 1st question regarding the touch screen's responsiveness while trying to unlock with password, I've experienced this myself, and while charging. Though I'm not really sure what causes this, to be truthful. I've found though, that sometimes locking and unlocking will get things to cooperate. I doubt it there's anything to cause concern with any hardware (digitizer) since you don't mention this as being an issue outside the unlocking of the device while charging. Mine was sporadic, and I eventually grew tiresome of the pattern unlock, and did away with it altogether. Perhaps someone else could chime in here with a better explanation as to why this happens. (?)
Now, to your more 'serious' issue. Seeing as how you have Clockworkmod Recovery (CWM) installed, you never want to allow your device to power down at the low battery state. You're lucky that you can at least -or at least have- been able to boot after a low power shut down. You may need to FXZ back to stock, if the phone will not boot at all. Can you get into AP Fastboot by pressing and holding AT THE SAME TIME the volume up +volume down + power buttons? If so, you can restore to stock and get yourself out of the soft brick. Here is a great thread with discussions by Fall of Enosis and jimbridgman, I suggest you read through this:

I've experienced the screen lag as well.. I think it only comes out when u are charging...usually i just d/c the carger then unlock the device and then plug it again..Something is still lagged...I relly don't know why this happens, but one friend has a Vibrant..and have this problem as well..So we aren't the only one whit this problem.

Edit: Also i'm on SCV7 so it's nothing to do with the rom.
For your second Q...Try to clear battery stats on CWM?? Sometimes when u flash a new rom u need to clear those stats...So give it a shot and let us know what happened.

This won't do anything for the OP's inability to boot. That's why I said that likely his best bet is to see if he can boot into AP Fastboot, so that he may be able to FXZ back to stock...

Cheers for the heads up, its not exactly a question, but I've seen questions on this board before so i thought that was ok.
Thing is, its not that it wont boot, it boots after i charge it for a while, but it states that the charger is not connected each time it boots, then shuts down.
Why should we not allow it to go into a low battery state when on CWM? I also set CWM recovery to start at each boot, and i have backups of just before and after i flashed the phone. Cant i just restore a previous backup rather than flash to stock?
And with the battery reset, doesnt clear any user data yeah? I have alot of stuff i would hate to lose

Okay, I thought from the thread title that at some point, the phone wouldn't boot after a low power shut down. If the phone is saying that it isn't recognizing the battery while charging, you might have some luck trying the methods I overview in THIS POST. The battery will NOT charge while in CWM Recovery, nor will it charge while in AP Fastboot. This is why it is imperative that you not allow the phone to get to such a low power stage, especially when attempting a flash. You can certainly restore via CWM either of the backups that you have, and see if the problem clears up. And with a battery stats reset, nothing is wiped except the battery statistics. All of your user data, applications, settings, etc. will remain in tact. Hope this helps...

The battery reset actually worked! I had to charge it for quite a while on the usb charger since it wouldnt charge on the mains charger. Once it was on i made a backup then cleared the battery stats, and now it detects the mains charger.
Cheers for your help guys i still dont get why it wouldnt charge on the mains charger when the battery was low, even though before it would charge before when the battery wasnt...
Well the thing is..i've been using my HTC ONE S for a while now...
Then after a while i tried to root my phone via recovery.
I unlocked the bootloader successfully since when i boot on bootloader my phone said on the top of the screen "UNLOCKED".
Then when i tried to get to recovery...it was stuck on entering recovery..nothing happened.
Installed CWM v6 touch and non-touch same results.
I was going to try TWRP but i went to bed.
Next morning during the day my phone ran out of battery. i mean 0%
i tried to turn it on when i leave it on the charger like an hour.
after an hour the pone didnt boot up..it just dead.
the pc doesnt recognize it at all...the charger makes a "bip" everytime i plug in the phone the led blinks a couple of times before fade again
tried hard/soft reset, tried to put it on bootloader, pressed Vol - and Power button, i keep em pressed for like a minute and nothing happened.
It doesnt show up a Qualcomm dispositive. i mean is not bricked, i never installed a custom ROM/RUU/
he worked like a charm the entired day before ran out of battery.
Tried to replug the battery nothing happened same results.
Sometimes when i tryed to only press the power button the screen flash a bit and then dies.
At the end i let the phone the entire night charging(more than 12hours)
Same results......
my phone doesnt have warranty....

Run the OEM RUU first ( you need to know what network the phone is locked too and choose the matching RUU, should you have a few options to choose from then choose the highest number or latest version, if it's unlocked choose the HTC RUU again the latest or highest definition).
http://forum.xda-developers.com/showthread.php?t=2094414
If all else fails ...
Send it back to HTC service centre. Best outcome they'll repair it for free, worst outcome they will tell you how much it'll cost to be repaired and if you choose not to repair then you have to pay P&P for device to be returned. The choice is yours!
Hope that helps.

When you mean you tried to replug the battery, does it mean you were able to open the casing of your oneS? It seems your problem is you have a bad battery, or else your battery is dead.

yeah i was able to open the phone, the battery is connected via pin to the motherboard (i though it was solder to the main base)
I'm going to try to charge the battery with an external charger, then plug in to the phone and see what happens.
Is all because of a bug on CWM....TWRP the best!

yes, as I can recall on the battery pin, you'll just have to connect the red and black pin to an external power supply, good luck mate! you can do it! :highfive:
Hey guys, something happened to my Moto G this morning and now it won't turn on. This has happened to me previously as well where the battery drained and charging it sorted the problem out.
But this time the battery was fully charged and now it won't turn on, neither does the screen light up when I connect it to the charger (with the 0% battery logo).
Something to note - I got an update from the play store for Motorola Boot Services. My phone restarted once and showed me the new boot animation (World Cup). Then it just went dead. Not sure if this has to do something with it.
I was running stock with an unlocked bootloader, root and twrp. XT1033 dual SIM.
Any suggestions will be appreciated. Any way to at least get the phone back to stock so I can take it back to Motorola.

The phone just won't turn on. Not even bootloader mode. Strangely the phone feels warm as if it is being used. I'm going to let it stay and hopefully it will completely drain out and then I'll try charging it.

Try again, with the device connected to the charger. This should perform a reset and a force boot, so it's just like removing the battery, If no luck, try to recover your bootloader by following this guide: http://forum.xda-developers.com/showthread.php?t=2623587
Press power and volume down keys for about 30-45 seconds and then release. This will turn of the device and then reboot to bootloader automatically. If this doesnt work, it should be a problem with the screen.
I've updated my boot services today and it didn't cause any trouble so far.
My advice is to leave it for few hours on the charger if it's really showing the charging picture and it shows 0% there.
HTC One M8, S-Off, Skyfall latest on 4.4.4, stock kernel, TWRP 2.8.1.0. Have been running Skyfall latest since a few days after its release, and TWRP 2.8.1.0 similarly. No problems to report so far.
I was using my phone today as one would, browsing Facebook through the app, and my phone freezes. Screen goes black, power off. Phone was probably at 80-85% battery when this happened.
I am no stranger to freezes and hard reboots, so I expected the phone to come back up shortly after this. It did not.
Tried to reboot via ADB. Couldn't detect the device.
Tried to reboot into recovery by holding Vol Down and Power. No response.
Tried to reboot into a soft reset by holding Vol Up and Power. No response.
Tried to force a battery recalibration by plugging in the phone to a charger* and holding Vol Up, Vol Down, and Power for two minutes. No response. (*the charger was not the stock HTC charger, as I don't presently have access to that, but was rather a generic charger rated for [email protected])
Somehow, miraculously, after leaving the phone plugged in for a few minutes more and fumbling a bit with (I think) the Power and Vol Up, the phone powered on, rebooted twice, and then entered the OS normally. Was stable for what seemed like about 5 minutes. After receiving a few text messages and in the middle of responding to one, it froze and powered off as before.
Last system-level tweaking that I did was to accept the latest SuperSU upgrade a few days ago. That needed to reboot into recovery, install a zip, and reboot again. All appeared to work correctly, and phone booted back up afterwards without issue. Appeared to be stable until today. I'm not blaming the SuperSU update just yet, and it seems an unlikely culprit given that the phone booted back up without issue and was stable for several days following.
Thoughts? Would greatly appreciate any troubleshooting ideas beyond these.
Update 1: After leaving it plugged in for a few minutes, I tried the battery calibration approach again. The device powered on and showed the initial boot splash (the one with the development notice in ugly red). I then released all buttons, and after a few seconds the screen went black. Would not respond afterwards. Beginning to suspect this may be a power issue.

Well the good news is that you aren't bricked, if the phone gives any signs of life then you are not bricked. Have you always installed SuperSu updates through recovery? I always select I believe it says "normal" and let it do it's thing and until now (knock on wood) haven't had any issues updating binaries that way. I would go back to stock and see if your problems continue or flash the previous SuperSu and see if it still happens.

Somehow, miraculously, after leaving the phone plugged in for a few minutes more and fumbling a bit with (I think) the Power and Vol Up, the phone powered on, rebooted twice, and then entered the OS normally. Was stable for what seemed like about 5 minutes. After receiving a few text messages and in the middle of responding to one, it froze and powered off as before.
Last system-level tweaking that I did was to accept the latest SuperSU upgrade a few days ago. That needed to reboot into recovery, install a zip, and reboot again. All appeared to work correctly, and phone booted back up afterwards without issue. Appeared to be stable until today. I'm not blaming the SuperSU update just yet, and it seems an unlikely culprit given that the phone booted back up without issue and was stable for several days following.
Thoughts? Would greatly appreciate any troubleshooting ideas beyond these.
Update 1: After leaving it plugged in for a few minutes, I tried the battery calibration approach again. The device powered on and showed the initial boot splash (the one with the development notice in ugly red). I then released all buttons, and after a few seconds the screen went black. Would not respond afterwards. Beginning to suspect this may be a power issue.

Make sure you aren't trying to power it on while still plugged in. The charging animation bug really rears its ugly head sometimes when trying to do that.

Well the good news is that you aren't bricked, if the phone gives any signs of life then you are not bricked. Have you always installed SuperSu updates through recovery? I always select I believe it says "normal" and let it do it's thing and until now (knock on wood) haven't had any issues updating binaries that way. I would go back to stock and see if your problems continue or flash the previous SuperSu and see if it still happens.

I would love to go back to stock if I could get the device to turn on.
This was the first SuperSU update that I can remember having installed, so yes, I've always installed through recovery. The update even prompted me that, for HTC devices, better luck is had via updates through recovery.

I'm unaware of this bug. When disconnected, the device still refuses to reboot via any of the usual reboot patterns (Power, Power + Vol Up, Power + Vol Down, Power + both Vols).

OK. So couple more questions....
Does the power light blink for a second and then go out when you connect power or does it stay on?
What type of device does your computer see the phone as when you connect it? Please try if you have not. Watch device manager while doing so.

Power light does not blink at all on connection. This is true both when connecting to a USB power adapter and to the computer.
My computer does not recognize a device. ADB does not report that a device is connected. Also, I use a Mac, so System Information does not report any USB device being connected. For comparison, I tried with my wife's Samsung S5, and it reported correctly in both places, so I know the cable and computer are working correctly here too.

Can you check dmesg on your Mac and see if you have any qualcomm devices show up near the end of the file? . Plug the phone in right before running the command.

Nothing from Qualcomm, nor anything related, upon plugging in the phone.
Using
Code:
sudo watch 'dmesg | tail -n 15'
(OS X requires dmesg be accessed with sudo), I saw the following come up upon plugging in the S5 mentioned before:
Code:
USBMSC Identifier (non-unique): 0x00000000 0x4e8 0x685b 0x232, 2
With the same watch in place, I saw no output at all for the M8.

I would suggest warranty route through HTC. You have got a brick.

Hi,
Background: Rooted, S-Off (via Sunshine), was running CleanROM (on the 444 firmware) and tried installing Vanir 444. ROM installed no problem, Gapps installed no problem, installed SuperSU 2.40 at the end and rebooted.
I've run into the exact same situation as the OP. Tried all the button combinations/adb stuff and the phone only boots to the initial white HTC screen but then goes blank. I've tried everything to get into bootloader but nothing seems to get me there. The phone vibrates when it "turns on" after the hard reset but nothing after the white HTC screen except a black screen.
I'm responding to this post in particular because my phone was/is showing the blinking power light when it's plugged in. Hopefully this is a good sign?
TIA for any help!
Matt

I'm afraid that I won't be of much help going forward. I sent in the device on a warranty claim.
I will add that, in the day or so following my posts here, I plugged the phone in again and to my surprise it began taking a charge again. I let it charge for about an hour, and tried turning it on - remarkably, it came up normally. It was stable for about an hour more, and then froze and powered off as before, refusing to once again turn on.
I left it alone for another couple of days, during which time my replacement arrived, and tried again. It began taking charge, and I left it as such for a couple hours more. This time knowing that my stable time was limited, and with a replacement phone in hand, I immediately restored the phone to RUU stock and locked it.
Your problem seems different from mine, in that my device was outright refusing to even take power or turn on. Best of luck to you, though!
Thanks for the info...I appreciate the response. I'm hoping that there's something that can be done but after 2 hours, trying every trick I could find via
Google with nothing to show for it, I'm keeping fingers crossed that it's something simple I'm missing. If I could just get into the dang bootloader!
Thanks again!

To add to this, I've let the phone sit for about an hour, untouched, and now the green light is blinking like it does when there's a SMS/email. Pushing the power button doesn't do anything.

For what it's worth for anyone that finds this info useful...can't take credit for this as I found it over in the One M8 forum. Thanks to @mpogr
I quote his post: "The problem was that my phone's screen was going blank after the normal boot screen, so I couldn't see when it gets turned off. I was simply pressing the Vol Up + Power for too long, so it would go into full reboot. I just measured the amount of time it was taking to do this (was ~12 seconds). So I pressed Vol Up + Power for ~10 secs, then released those and pressed Vol Down. That finally brought me into Fastboot.
I could have probably gotten the same result by pressing Vol Down + Power, however, the phone screen was blank all the time, so it was difficult to understand when I should have released the Power button to let it go into Fastboot."
I held Power/Vol Up for 10 seconds (as he described) and then let go and immediately held Vol Down only...after about 3 seconds, bootloader screen came up and I was able to get into recovery and restore a backup.
