[One (M7) Q&A, Help & Troubleshooting] nbelshaw:
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....

[One (M7) Q&A, Help & Troubleshooting] Bob2702:
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. :o

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!

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).

Go to device manager and connect your phone. What do you see?
[One (M7) Q&A, Help & Troubleshooting] inferno7799:
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.
[One (M7) Q&A, Help & Troubleshooting] danielr18:
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.
[One (M7) Q&A, Help & Troubleshooting] inferno7799:
Damn. Really? After just using the phone for a day? Today just really isn't my day.

Would there be any other things I could try? Any jigs to force it to boot into bootloader or anything?
[One (M7) Q&A, Help & Troubleshooting] n1234d:
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?

Blue Screen?

I'm having the same problem that others have except mine is a little different. I have not rooted or changed anything from my stock HTC One X. I woke up to a dead phone and when I tried to charge it, there was no red charging light. I was able to get a red light for a bit using the trick of plugging it into my computer via USB. My computer does recognize the Android device in Device Manager and it does make a sound when I try to turn on the phone. Problem is that it only gets to the HTC screen and then it goes dark blue. I haven't seen anyone mention the dark blue screen. I can't power off the phone. I tried charging overnight to see if the red light would pop up but it didn't and the dark blue screen is still on.

I've been able to get the screen up where the FActory reset option is so that I could power down a couple of times but have a hard time getting it back.

Is my phone screwed? (It's over a year old)

Has anyone had the blue screen though? A dark blue glow on the screen? I finally was able to get my phone to charge because the red light came on and then turned green after a few hours but when I press the power button, it goes to the dark blue screen after the HTC Quietly Brilliant screen.

HTC One m7

Hi,

One day my phone dead i put it on charge and the light was on after at least of 10h charging it i could turn it on and then phone was going on for while and again i had to charge it for long time and same story. So at this point i told battery is dead i bought new one, replace it and now no red led, won't turn on but windows recognize it as "hid-compliant device" and "USB input device". I tried all tricks with buttons and freezer :D after this i told the usb port be broken so i got new one replace it, still nothing. Phone was on charger for 3 days before i replace usb port. Before i change port i checked battery charging voltage between P+ and P- which was 1,8v after port change it was same(when i was checking voltage, battery was disconnected). There is my question does anyone know what the voltage should be and how to charge this battery outside(not trough phone)?

I think i have fix it by cutting up wall charger usb end, i connect + to battery plus + and same with - to -. 5 hours later I put back phone together and now when i connect to charger red led blink but is not going on yet as i think is drained.

Only led blibks a while

Hi,

Thanks for the advice. I have faced a similar situation and followed your instruction. My problem is, after plugging in the phone to wall charger, my led blinked for a while (1-2 minutes). However, after that it stopped and no sign of charging like before.

Can you help? Thanks in advance.
[One (M7) Q&A, Help & Troubleshooting] PedroAndre82:
It's something

I dont know if this is a solution, but I managed to reboot my phone with this problem by doing a simple trick, that sometimes works and sometimes doesn't. What I did is to take the battery out and put it in, but really fast, while the charger still plugged in. This way the charging led was again on, but not for long... So I did it again but without the charger and I tried the VOL - and POWER and then the phone rebooted on bootloader.
[One (M7) Q&A, Help & Troubleshooting] auspony:
Thanks - doing this actually started the phone but it never boots into OS. It keeps going off and rebooting into the HTC splash screen and then off and all over again.

[One (M7) Q&A, Help & Troubleshooting] Hesster:
Sadly, my M7 was struck down by this problem yesterday.

I was reading an email, I set the phone down and it spontaneously rebooted, then hung on the HTC screen. I was able to get into fastboot, but it rebooted every time I tried to get into recovery mode. I pulled the SIM out, then got a screen saying to enter the password to decrypt storage. After that I was able to get into TWRP, but it said it had 0 bytes of storage. I formatted the data storage from the menu and rebooted, but the screen went black and that was it. Even the hard brick fix in Linux couldn't save it.

At least I had insurance, so the replacement is on its way. The $175 deductible sucked, though. I may sell it and pick up an M9 when it has root and some decent ROMs.

D-e-a-d

My 19th month old, T-Mo HTC One powered off the other day at about 50% battery. It was S-OFF, running Viper 8.0 with the latest firmware, hboot 1.52 and radio for T-Mobile. If it wasn't for wear between the back cover and the back case, the phone can pass for new - never dropped, no scratches. It had worked great up until flashing Viper 8.0 about 3 weeks ago, BT has been sporadic and the light sensor didn't work right during calls. It would also feel sluggish sometimes opening basic apps.

None of the fixes have worked. Tried holding power, power + vol down, power + vol up, power + vol down + up both in front of a 13w CFL and not. I tried powering it on while plugging/unplugging it into a Macbook - no response from the phone and computer didn't recognize anything was plugged in. Put it in the freezer for 1 minute, no luck. Tried two different, working wall chargers and cables - nothing. It's been in a wall charger for about 2 days now.

After reading each of the posts in this thread and more, I feel like its a hardware failure and might bring it to a T-Mobile store to have it sent in for repair - if just to see what failed. I'm kind of bummed that a $700 phone lasted 19 months though. Looking for a replacement but all phones seem just repeats of phones from 2013 - no new features, nothing exciting or new. Probably going to find a $200 Moto X to last until Google's project ara becomes a reality.

Ya, I'll post back when I hear from them but if you call in the meantime, it was actually pretty simple to setup sending it in, I just called the number on their support site for repairs.

The one thing I would say is that they'll tell you that you're responsible for shipping the device to them and I was in such a hurry I got it out via Priority USPS like 20 minutes later. About 2 hours after that, I was emailed a shipping label from them. So if you want to save $10, wait a little while after calling in.

New weird problem...

Okay, I have the M7 with PAC 4.4.4 12/31/14 Release. Tonight my phone completely died and I plugged it into my wall charger and it would not charge and no lights lit up at all just like yours. I read your post, the first thing I tried was Hold Vol Up + Power and while holding I plugged it into USB2.0. My computer immediately recognized it but it gave me unrecognized USB error like the device was malfunctioning (Not the usual no driver error). So I installed HTC Sync and tried again and it did the exact same thing so it's not a driver error. Then I continued reading posts on the thread and you had mentioned using a 3.0 port so I did. This time no error popped up and I couldn't find any device for it in device manager so I let it sit for like 10 mins and the charging screen popped up on my M7 and the solid red light came on so I tried to boot and it booted just fine, so I thought the no charge issue was fixed. So then while it was booted I took it off the computer port and plugged it into my wall charger and it still wont charge plus the red charge light goes dim solid like normal then goes off and flashes bright red and repeats but wont charge. I checked to see if it was a notification since I was fully booted but it wasn't. So then since I had about 15% charge by this time I powered off then tried plugging into wall and it does the exact same thing it originally did no charge no lights but as soon as I plug it back into the USB3.0 port it charges like normal. I thought this was extremely od... Everything worked completely fine before it died and now my problem is no wall charger and now no ADB/FASTBOOT/MTP on the computer... I am completely mind boggled any ideas?

I managed to revive mine.

I tried all the tricks posted here. nothing worked.I had no red light and no vibration.

What I did was I got frustrated and opened the phone with this method

https://www.youtube.com/watch?v=sbL_-11JIZU

After that I took a picture of the back of it ( to know where which wire goes etc.)

Unhooked everything which was possible. I wanted to take out the battery.

But my screw driver was too big, So i left to friends house to get a smaller one. I left the phone with all wires etc. unhooked.

After 4 hours when I came back without small enough screw driver, I just hooked all wires and put it on charge.

It worked.

I don't recommend This method at all, but if your htc doesn't have guarantee or the repair is way more than phones worth.

Then try it. I hope it helps someone else as well. I take NO responsibility

Big Verizon OS update today, now the phone won't power up.

My solution:

1. plug in power charger and charging wire to phone; 2. on the phone, hold power button, volume up AND down buttons concurrently. After 10 seconds the phone powered up and my huge affection returned. Now I'm happy boyagain. :laugh: If you got arthritis like me, holding down three little buttons steady for ten seconds was quite the task.

HTC M7 sudden death issue

Good day guys,

My HTC M7 was working fine until i received some updates. The phone needed to be restarted but never turned back on. I left the charger plugged in for almost 2 days with no charging LED on. I tried pressing the volume + power buttons, power alone, all possible key combinations for at least 15 seconds each and nothing. I even tried holding the volume down + power button while holding the proximity sensor close to a 100W fluorescent bulb but nothing. Any help on this will be greatly appreciated guys!!

Bonjourno,

i`ve got the same issue like lots of people mentioned before: No LED while charging, blank screen, no buttons light up. I tried holding power button and volume up, down, both. I tried the proximity sensor trick, but got no luck. But: the phone turns on, cause the official HTC boot sound appears. Does the sound also came up at other "bricked" devices here??!?!

So, now i`m trying the "last forever wall charger trick". Maybe i will leave it charging the next days until the red charging LED will appear.
