HTC One M7 non-rooted, hard reboot loop - need help - One (M7) Q&A, Help & Troubleshooting

I've got an AT&T HTC One M7. It's non-rooted and has stock firmware. Android updates from AT&T are installed when pushed. It's all pretty routine. As of yesterday evening, this phone started rebooting and won't stop.
If I leave it alone, it vibrates (normal startup notification), goes to the green on white "htc" screen for a few seconds, then goes blank and starts over. I can get to the bootloader screen, and I've gotten it to start in safe mode as well, but it always restarts again within a few seconds.
Things I've done/found:
- Holding down the volume down button while it restarts takes me to the bootloader menu, but the buttons don't seem to work correctly when I get there, and it always restarts again within a few seconds.
- I managed to start it in safe mode a few times--I think by holding volume up and volume down at the same time--but it restarted before I could do anything.
- I removed the SIM card. Same thing.
- I let it reboot until it died. As soon as I plugged it in, it started the same thing again.
I'm starting to think it's hardware failure, like the power button is constantly making contact, even though the button feels fine to the touch. Note that I get to the bootloader just by holding the volume down button. I don't have to touch the power button. I'm not certain whether that's normal. Can anyone give me any ideas or even just verify that it seems like a hardware problem?

[Q] N6 AT&T: Screen will not turn on

I've had my phone almost a week now. Last night the screen stopped turning on. I can hear notifications telling me the phone is on, just not the screen. I did a google search and saw similar problems on the N4 and N5. I have tried there methods now over 100 times and still no success. I am holding POWER + VOLUME-DOWN for 15-20 seconds then plugging in USB port but this in a number of variations is not working. Is anyone else having this problem and do you know of a fix for this?
Phone is not rooted if that helps.
Make sure you still have battery (plug it into the wall) then hold down volume up+volume down+power until you get into the bootloader.. From there you can flash factory images or try going into recovery (use volume up to scroll to recovery mode) and do a factory reset. Once in recovery you will need to hold down the power button and tap the volume up button once to bring up the menu for factory reset.
tried that, no luck since the screen doesnt turn on. any other ideas?
you got a sod(sleep of death). the only way around this is to press the power button for 20-25 seconds straight, then reboot. or, there a possibility that your screen stopped working.
Have you tried plugging it into the computer and giving it adb commands to boot into BL?
I wonder if this is an issue with Android in general on rare occasions since KitKat. I had this problem too on my LG G2
yeah, i tried all of these methods and gave up. at&t gave me a new one since i was under 14 days. the lady said they had a whole batch of n6 they had to ship back because of problems and that the newest batch "should" be problem free.

[Q] ATT Moto X 2014 Freezing Constantly

Hello all,
I got this phone about a month and a half ago, and since I got it I've noticed a lot of freezing and crashing (more so after the 5.1 update).
Some examples:
-I try unlocking the phone from active display and the screen goes black. The only way to get out of it is to hold the power button to restart.
-Sometimes the phone freezes on the lock screen randomly, and when I pick up the phone to look at it, the time is wrong and I can't physically unlock the phone, only turn the screen on and off, leading to me having to hold the power button down to shut off and restart.
-When on some apps, like twitter for example, the phone freezes, and I cannot do anything except turn off the screen by pressing the power button. When I try waking the phone, it stays black or sometimes theres a flash of the screen I was on before, and then it goes black again. Only thing I can do here is hold the power button down until "Power Off" shows up on the screen, and I press that to shut the phone off.
Today I cleared the cache, and since then the phone has froze once, causing me to do a hard reset. What should I try next? Any idea what the problem could be?
Thank you for the help.
I have pretty much the exact same thing going on. It started last night... I first noticed I had some charging issues where the phone wasn't charging very quickly after the battery died (after a day of heavy use). I let it sit for awhile, then it booted up, and it showed the motorola splash screen. It gets all the way to the lock screen, although I'm unable to unlock the phone. The screen goes dark. It appears to still be getting texts and the like- although this screen blackness issue makes it so I can't unlock the phone. The one thing I can do is hold down the power button and turn it off. I've tried loading fastboot and doing a factory reset, although nothing appears to happen and it boots the same way. The other thing about it is that it appears to be running hot- way hot. Any ideas? I'm running stock rom, Verizon network, just updated to 5.1 when it came out last week.

HTC One Bricked - Turns on, but can't access fastboot or recovery

So my friend sold me his busted HTC One, telling me it wasn't turning on. I took it upon myself to get it fixed up.
It seemed completely dead, but after plugging it in to charge, and holding power + volume up + volume down, I got it to turn on to the HTC screen when charging, then turn off. I can access the bootloader screen by holding power + volume down, but the bootloader screen goes crazy.
The first option will keep selecting itself, then going back and loops like that. If I try scroll down, it instantly selects the thing I scroll to, which is either reboot or power off.
If I select recovery on the main screen, it boots to the HTC logo and turns off.
Not too bummed, as I only payed $35 AUD, but really would like to try get it fixed up.
Thanks!

Sounds like maybe the power button is stuck on. Hence the reason it is auto selecting everything. Also it would cause the device to force reboot.
When it boots to the HTC logo, are the Capacitive back and home buttons flashing at all?

Ahhh I thought that may be the case! Should be a fairly easy repair then. The back and home buttons do not flash at all.

Major Note5 problem out of the blue, help!

My GF was making a call with my Note5 and it popped up Process System isn't responding - OK, Wait - neither of which did anything. also it was vibrating every second or so, probably while trying to bring the system process back up and it crashing again.
Holding power didn't seem to turn it off but eventually it restarted to SAMSUNG screen, where it CONTINUES to vibrate every second and never progress.
Holding power does not shut it down.
What the heck do I do now!?
This is a relatively new phone but I bought it from some guy who I can't get back in contact with. It had been working fine for a week, rooted, running Dr Ketan rom.
edit: OK, after about 5 minutes of it vibrating at the SAMSUNG screen I tried holding power AND vol down, this (perhaps coincidentally) then rebooted it and it seemed to come up fine this time. It's a real pain not having a removable battery when something like this happens.

Power Button problem ?

Hello!
Not later than this morning I realized a problem on my Idol 4. At random moments it restarts. When it is on the screen of starting up it continues to restart in a loop. I came to the conclusion that it is a problem with the power button because when I press the volume buttons to enter download mode or even recovery, it quit the download mode (which is done by pressing power) and select options automatically in recovery (which also done by pressing power). So when it restarts I just press the power button randomly, try to pull it out of the phone and then it stops restarting. But again, minutes later it restarts... The button seems not broken or anything that kind but maybe it's in the inside ?
So just questionning how can I fix this.
Thank you a lot !
I think you can just pop the screen off and buy a replacement the idol three was pretty easy to replace. No special tools just used my nails
