My One S never boots up and keep restarting automatically

My One S has worked fine until now. Now, however, it suddenly started to reboot nonstop. I get the first two starting screens, then it shuts down, and in a few seconds it starts again. The process continues until the battery is dead. I've tried to hold in the shutdown button for various amounts of time and it leads to the process halting, ie the mobile keeps being off. But once I release the button the process continues once again.
Any ideas?

Can you get in to bootloader?
Power down then power + Volume

Dont seem to work. Ive tried multiple times to press both power and volume while the One S is shutdown. Have anyone heard of this problem before?

Are you HTC Dev unlocked?
Rooted?
Hold down Power you will see all 3 keys at bottom flash just keep holding,this should hard reboot
If not reboot device when screen and lights go off hold volume down then factory restore

This didn't work on my phone :S I tried hard reboot and factory reset, both doesn't work. :S
What else I can do, I'm so panicked at the moment, please help me.
I can't get to the menu screen, it just keeps reloading between htc one s and htc logo please help.

I was having this issue the other day. It took me a while to get it figured out and this thread helped me: http://forum.xda-developers.com/showthread.php?t=1630459
To get into bootloader was hit and miss for me. I found that the best and most consistent way was to hold down the power + down volume, let go of the power while holding down the down volume after 5 sec and then press the power again then let go of both buttons.

[Q] Volume Down + Power button doesn't work

Pretty self explanatory post. I'm trying to boot my phone into bootloader mode, but holding power and volume down just reboots it normally.
I have a AT&T HTC One X. Any ideas?

It's a timing issue. There are two ways you can do it.
While device is switched on
Hold the volume down button, then hold the power button (so you're holding them together), the button lights will start to flash, they'll stop flashing and the screen will go blank, after a couple of seconds let go of the power button but continue to hold the volume down button until the phone boots into the bootloader.
While the device is switched off
Hold the volume down button, then hold the power button (so you're holding them together), after a couple of seconds let go of the power button but continue to hold the volume down button until the phone boots into the bootloader.
It's very important to not let go of the power button until you reach the bootloader with either of those methods.

I learned that the hard way. Lol

This is almost always a matter of pilot error. Unless the phone is bricked, or an actual physical malfunction of the vol button, it will always be able to go to bootloader. Just follow timmaaa's suggestion above. The primary error, is that folks don't realize you are supposed to let go of the power button but keep holding vol down. Understandable, since the usual direction is just to "press power and vol down".

How to power on a phone with a broken power button?

My LG G2's power button and volume rockers appear to have stopped working. My phone is off and USB debugging is off. Is there any way I can power my phone on? Thanks!

The problem is that my phone is off! And I can't turn it on without using the power button it seems.

Is it the button itself that is broken or the functionality of the electronics? I once had to replace the physical button after the guts had fallen out of it. Got to the last step of rooting my phone, went to press that rocker button and ...nothing. I always used the virtual, on screen button for photos, so I never even realized that it was dead. They can usually find them somewhere online

I think it is the electronics because at one point my power button/volume buttons were randomly getting pressed without my input. But, I really don't know for sure.

Reboot phone with no power button

All phones have a recovery mode which can be accessed by pressing volume up or down (only one) while inserting the USB cable. This powers on the phone for download mode allowing you to restore software.
As mentioned best method is to repair the faulty button but I would try restoring STOCK image/rom first.

Possible solution
Hope that this trick could help someone.
Situation:
- broken power button
- lg g2 off
- WORKING volume button
After lots of tries to power on that damned phone something happens:
1) Charge g2 until 100%.
2) Hold both volume button (UP AND DOWN) and insert power supply
3) be ready to disconnect the power supply immediatly when the lg logo appears
4) disconnect charger (Screen will goes off) keep holding volume button
5) reinsert power supply and when screen goes on release and rehold again both volume button.
And... Magically lg g2 starts!
I really don't know why this procedure works but i currently use this trick to power on the device when accidentally my lg goes to 0% -.-'
Some advice:
Before doing all this combination i've tried holding both volume button when the device was off.. For some reason the red led (charging color) flashed five times then this trick works. Don't know if was just a coincidence. But triying can't do any damage!
So... HOLD FOR MORE TIME YOU CAN THOSE ****** BUTTON.
And pray.
Hope that this will help someone

this worked for me. although I found that I did not have to reinsert the power supply nor did I have to rehold both volume buttons again at the end.
so 5) when screen comes on, release the two volume buttons.

Install Volume unlock, it'll make your volume button unlock the screen

Use ADB Commands to first connect your phone with your pc using a terminal and then use some other adb commands to power it on.
Google for some ADB commands.
Hit thanks

Lg g2 D802 here, non-responding power button. I power on my Phone just by plugging in the power cable and pulling it out when the logo appears. Nothing else. Screen on/off by knock-on funktion.

Nexus 5 stuck in safe mode because of volume button?

Hello,
My Nexus 5 won't start up without going into the bootloader and switching through all the options because it thinks the volume down button is being pressed. The phone has been doing this for about a month and a half but lately the volume button hasn't been that bad and at sometimes didn't seem like a problem anymore.
Now when I turn my phone on, the bootloader is cycling through the options and I press the power button when it lands on "Start", the phone boots up but then it's in Safe Mode and I don't know what to do now.
Thank you for the help in advance.

It just fixed itself after pressing the volume down button for a while. I fear turning my phone off or pressing the volume down haha. Should I just buy a new motherboard eventually?

Help: Recovery mode

Hello, I have a Galaxy S10 lite with black screen. I have tried to turn the recovery mode in. At the beginning this seemed impossible, as I tried "all" possible key combinations holding them for several second. Then suddenly, after more than 1h of tires, it entered in the recovery mode, but turn it off again before I was able to select any option. I tried again several combinations but I was able to success yet. Do you know how could I get the recovery mode again? any idea what is happening?

The phone does not charge

My recommendation: Take phone to authorized service center and let them try to fix it.

After one night usb connected to the laptop, but black screen at every time, I tried to enter in the recovery mode again, and it worked! no idea...
