Help HTC one wont charge or boot

So my htc one running cm10.1 died and now wont charge or boot. ive left it charging for a while and nothing no led or splash screen when i hold the power button, also the charger doesnt get hot so i assume no current is passing thru it to the phone, ive tried other chargers and cables and nothing also tried plugging it in nothing works. I dont have insurance on it so thats not much of a option. any other suggestions im having a similar issue to whats in this thread http://forum.xda-developers.com/showthread.php?t=2257448
Device htc one sprint Recovery twrp kernel stock cm10.1 running cm10.1 nightly 6/7/13, also i noticed that earlier the phone didnt charge when i powered it off need help guys please.

anyone know anything else to try?

Weird, I would let it sit for a few hours to make sure the battery is completely dead. I bootlooped mine a while ago and even holding down power wouldn't make it reboot. After letting it sit, try a different charger see if the LED light starts blinking when you plug it in. It should stop after a few min turn solid, I would wait at least 10+ min then boot the phone into bootloader to hit recovery to restore a nandroid.

Try holding down power and.volume down at the same time under a bright light..I'm not kidding

it's power volume up to reboot, you've probably already tried

Had a problem with no charging after rooting, though I think it had more to do with my car charger. Contacted HTC and they suggested holding volume and power buttons simultaneously for two minutes to re-calibrate the battery. My phone is charging again and no more issues since I tried that. Worth a try.

The bright light thing worked for me. I was in a similar situation after my phone shut down during an OTG transfer. I tried everything and nothing worked. I figured I had nothing to lose, so I held it directly over a 100 watt light bulb and it booted right up.

I've tried with no luck, and while were at it just because you can get it to come back on with such a peculiar method we must ask ourselves how many times we would be ok with doing that to bring our phone back to life? there must be an answer to all of this somewhere but its kind of hard to pull any logs off and device that is 100% bricked.

[HELP] HTC One not turning on

Just wondering if anyone can help me out here..
My HTC is not turning on at all. I was using it fine, nothing was over heating and it was just in my pocket. I went to check on my phone and it was just off. Is there anything I can do, or possibly take it in for warranty. I have never owned a HTC so I don't know where to go for support. I am from Sydney Australia. Any help would be appreciated. I have left it on charge for 30 minutes - And nothing yet, not turning on

Havent rooted or unlocked at all I assume?
No lights or anytihng coming up? Try any button combinations, power and volume down, try it while the phone is not plugged in... report back with any findings.

It is unlocked and rooted.. Tried all combinations before posting this thread. Lights are not on at all when charging. At this point it seems dead, but the question is how?

Although when I hold the power down when plugged into my PC it makes the unplug sound and while still holding the power button long enough it has the plugged in sound. But nothing shows up on PC

Not sounding good at all. Hopefully someone else chimes in on this matter and has other ideas. Good luck.

Yeah i couldn't. it says Waiting for Device

Tried everything.. I bought this phone from Gumtree Australia a few months ago and that person got it from the Optus store via Contract I believe. But I don't have the Receipt however, I have the box and accessories and warranty stickers that come inside the box. Would I have to go through Optus store or is there a HTC One centre like they have Apple and Samsung centres/stores..
This question is probably only for Australian users

I heard of this before... Try plugging it into your computer and leave it for an hour. Then... (While still plugged in) hold it under a bright light and hold power + vol down, for a few minutes. I think this problem occurs because CWM allows the voltage to get too low for the phone to start. Good luck man

Well, when I heard this in another thread he said he fixed it by plugging it into the computer for an hour or so. Then the led turned red, then he put it into recovery and booted right into the ROM. Np hope it works out for you

The light has to be facing the phone. You can see the two sensors on the top left on the front, point the light there.

I fix mine by let it charge on wall plug for 4 days straight until red LED started to ON back..lets it charge for another 1/2 hr n press the power button to ON the device..weird..4 days just to gain back some juice due to battery completely die..

HTC one won't turn on, No LED, no flashing Home/Back button

I upgraded to an HTC One a month ago in T-Mobile and now randomly the phone won't turn on. The phone is rooted, unlocked, custom recovery, and has the Android Revolution ROM. I installed everything the first week I got it and it has been working perfectly fine (No freezes, battery discharging has a good rate) and everything works (Wifi, 4G LTE, Bluetooth). The phone has not been dropped, water damaged, or exposed to any excessive heat, so it should not be having problems.
Yesterday (9/14/13), I was using the phone just fine around 8PM with my friends in a restaurant and everything seemed fine. A few hours later when I was walking down the street, I take my phone out of my pocket and when I hit the power to wake up the phone nothing happened. I pressed the power button for 10-20 seconds and nothing.
When I got back to my room and plugged it in, the LED did not turn on or anything and when I pressed the power button again after being plugged in, nothing happened. I charged it all night and decided to work with it today, but nothing has helped. I have tried holding the power button and volume keys for minutes, holding power button and nothing. When I plug in the phone to the PC it detects it (Windows USB sound in) and when I press the power button for around 15 seconds it makes the sounds but then it makes the removed usb sound.
Since the phone is Rooted, unlocked and has custom recovery and rom, I'm not sure warranty would help, ALTHOUGH since it doesn't turn on and physically is not tampered with, they could get it to at least turn on.
Please help me out here as I am a college student and really need my phone for work and to stay in touch with my parents. Thank you, and I apologize if I didn't follow a posting guideline.
P.S. One of the causes could be a drained battery, but the charging all night should have helped.

Try holding the power button and volume down buttons down, while holding the proximity sensor directly under a very bright light...

This actually happened to me on my first HTC one I couldn't get it to do anything I ended up sending it to HTC I knew they would deny my warranty claim because of the bootloader and ROM but I knew they would have to turn it on yo figure it out. They called me to tell me that it was not covered and said it would cost 215 to put it back to regular I denied and paid the $35 diagnostic fee when I got it back I booted straight into fastboot and flashed my backup.problem solved

This actually sounds like a great, thanks , but before sending it out I think I would like to try other solutions since it would suck to not have my phone for 2-3 weeks. Also, how long did the whole process take for you? (Sending it out, "repair", and getting it back)

This happens to a guy in another thread. He fixed it by leaving it in the wall charge until the red LED turned on, it took 4 days on the charge.

Hey it actually only took about 1week take it back to your carrier have them send it for you. I also heard about leaving it on the charger for a long time I tried over night and it didn't work the next thing I did was send it to "repair" but if you have the patience leave it on change for a few days first

I have a Verizon HTC One exhibiting the exact same symptoms. The battery went dead after a long day and it will not turn on or charge. I have held the proximity sensor in bright light while powering on and while holding both vol up and power. Neither seemed to change the problem. How bright of a light are we talking? Thanks in advance. I am also curious why this works....

Maby i can help^^

Its so that if the phone is in your pocket it won't start up as the proximity sensor detects the phone is in your pocket so tells it not to start up. Sometimes the sensor doesn't work as it should and needs a really intense light to overwhelm the sensor and let the phone start up.
Bobbie

Put it under a desk lamp!
I had the same exact problem. My phone couldn't turn on after it reached 0% and there was no orange light when charging. I put the phone right under my desk lamp and held the power button for 15 seconds and it turned on. Thought people were just trolling... The battery was at 1% when it turned on. I already left the phone in wall charge overnight. Guess it was not charging very well. Thanks for coming up with this solution!

It worked!!!
WOW The light over the sensor worked for me too!! I'm glad I came to this forum first!!:laugh::laugh:

Doesn't work for me
This REALLY sucks I just got this HTC One used and I was using it all yesterday and this morning with no problems. Then all of a sudden a couple hours ago it just shut down - I was just browsing the web, so it wouldn't have overheated.
Now, it won't charge (the LED doesn't come on) although it was at about 50% when it shut down. I can't get into the bootloader or recovery, and ADB doesn't recognize that it's plugged in (despite Windows playing the little jingle indicated it's been connected).
Ever since then I've been scrounging the web for answers, What exactly have you guys done for this light trick to work? Because I've held it under a bright LED and under a desk lamp with a 13W CFL bulb, while holding power + volume down, but haven't had any luck.
How long have you guys held them down for?
I haven't even seen the capactive buttons light up (although it's just kinda hard when you're holding it under a light, so maybe they are flashing I just can't see) and the only sign of life from this is the fact that Windows installed Qualcomm drivers and plays the jingle indicating that it's detected a device.
EDIT: Forgot to include, I've been trying to leave it sit charging (one person mentioned their friends' One worked after leaving it charging for 4 days - I'm not sure I can wait that long, but if I have no other option I will).
Also, should I leave the SIM in or would it not matter (personally, I don't see that making any difference whatsoever, but I really don't care at this point)? And should I alternate light/darkness while holding the buttons under a lamp, or just leave it under the light and hold them? (I've tried all of these things, but I'm willing to pursue whatever avenue had the greatest success rate).

Ya, I tried looking into that before, and there's nothing there. Now I'm trying to find out what/where that Qualcomm driver is that was installed.
EDIT: I DO see it in the Devices/Printers as Qualcomm HS-USB QDLoader 9008 (COM3).
I've also installed HTC Synce Manager, but I'm not sure if that just automatically installed the drivers or if there's something I should do to manually install those.

Sorry to hear that. You are hard bricked, send it to warranty.
Edit: The motherboard is fried and HTC would have to change it. The phone is used so contact the seller and ask him for warranty information.

Well, since you're under warranty, doing anything else just doesn't make sense. And using jtag would require you to open the phone, and trust me, you don't wanna do that to this phone.. Just out of curiosity, what are the first 5 digits of your serial no?

[Q] HTC One Switched off and Won't turn on

Hi all,
I have purchased a HTC One while in US a month ago from AT&T. I am now in India and the device worked perfectly fine until two weeks ago, it switched off automatically.
I tried a lot of combinations mentioned in the forums and also contacted the customer service (both in US and India) and they requested me to try holding the Power and both Volume buttons at the same time for 2 minutes. I did this for 10 minutes and it won't work.
When I connect the phone to Wall socket charger, the LED won't lit up. When connected to my laptop, the windows O/S makes the connected sound but nothing happens.
I really appreciate any help in this matter. Thanks in advance.
Kind regards,
Krishna Menon.

Press and hold the power+volume down buttons. Once the home and back button lights start flashing, keep the power+volume down buttons pressed and plug it into your pc.. It'll connect and install necessary drivers and your phone lights will stop flashing, and it will eventually boot up in hboot.
It may take a few tries
Ps: Always use the thanks button

Anyone help me how to unbrick my phone? Appreciate the help.
Thanks & regards,
Krishna Menon.

Hi nkk71,
I tried this method without any success. When I contacted the HTC global support, the support person did mention this method. I tried holding the power + volume up + volume down buttons continuously for 15 minutes and nothing happened (my fingers hurt afterwards, #on a lighter note)

Unfortunately "qhsusb" is usually a hard brick and needs a motherboard replacement
for one (or two?) people, the phone miraculously came back on for no apparent reason (if memory serves, for one guys it came back when the alarm rang the next morning), but other than that it's usually considered a hard brick, and needs hardware fix.

Thanks nkk71 for this quick response. It's very unfortunate that my phone requires mother board replacement.
I loved the phone a lot. Now, I have to shell around 15K I believe.

No warranty? Sorry mate
you could leave it in the charger for a full day, and see if it comes back to life, and power it completely off while charging, not just the screen off.

I bought this from one of my US friends and now in India and I wasn't able to properly contact him. Lesson Learned for life. Not to purchase without proper documents.
I have put the phone charged for straight four days without removing in the wall socket. Nothing.

So I've been reading around, and came across QPST, and some guys have unbricked a hard brick using this tool. Is it possible to somehow make it work for the One?

Don't know what QPST is but i do remember there was a tool a while back for other phones to fix the Qualcom_HUSB mode, but I don't think it was ever updated for the One.

I'll take a closer look later, but if it was available/working for the HTC One, then i'm sure someone would have mentioned it by now.

I followed the steps mentioned in one of the posts on QPST; but as my phone was not detected, the COM port was stated as Not Available in the QPST configuration s/w. Don't know what else to do.

I thought I would add to this thread an obvious step that sometimes gets forgotten.
I assume you attempted to charge your device in multiple sources: wall outlet, computer, etc.
I suggest you try some more, ideally varying cables and power adapters.
I experienced too many times - and even once with the one - the same exact brick you're describing and most of the times, the only solution was the above: find a combination to charge the device when its battery is completely depleted as in this situation they're more picky as to the source of power

[Q] HTC ONE Wont Turn On. Suddenly Stopped Working

Hello,
My Phone Suddenly Stopped working while i was accessing an app on it. I suddenly got app fore close errors of almost all the apps running in background. Than phone lost its signal. i tried force rebooting it by holding on the power button. the button lights (at the bottom) blinked for few time and my phone got off. And never turned back on. I am not getting Red Charging LED. i tried all the combinations of power button with volume rocker up,down, holding three buttons simultaneously. i tried charging my device on regular intervals from 15 minutes to 2 hour. but it wont turn back on. i was on insert coin 6.0-5. i am using original charger to charge my phone.
Please tell me any alternates i should try.

Connect it to your pc. Look in device manager. Does it say something like QHS-USB DLOAD?

Well, don't bother, your phone is hard bricked, take it to the service center and get it repaired. They'll change your motherboard for you.

well That Sucks. Will they change it under warranty? My bootloaders were unlocked nd i was running on Insertcoin Rom. Is There any probable reason for such cause?

Yep, they won't have a clue, they can't turn the phone on either. I don't know about a reason, mine bricked in the same way, was running ViperOne and s-off, unlocked. They replaced it for me, no questions asked.
