Hard reset? - One (M8) Q&A, Help & Troubleshooting

Anyone know how to hard reset this phone? I'm stuck on the boot screen and have been holding down the power button for at least a minute, and nothing.
Edit: Never mind. Power+Vol Up.

Commonly referred to SOD or sleep of death, search the forums next time.

Uh OHHHH

After devunlocking last night, now my phone is messed up
The problem is the back,windows and search button no longer work, the portion of the screen that they take up is now like an extension of thescreen it just selects stuff as if it were at the bottom of the screen. Any help to reset all the files in root to factory, I tried to hard reset and soft reset.
Maybe I screwed up the registry or some files. Thanks for any help
try factory reset. hold camera + volume down + power. when phone vibrate release power button while holding the other 2 buttons. should prompt you to reset your phone. hope that works
Thx
I tried that but it enters USB Host mode, I also tried holding down up and down volume and power button to reset which resets it but doesn'tfixmy problem. it's acting like the part of the screen where the windows, search and back button are are now part of the regular screen and those 3 buttons no longer do anything.
This sounds rather like a hardware error. Your calibration of the touchscreen is messed up. I suggest you send it in. You still should have warranty?!
Btw. I don't think this has a connection to unlocking the phone!
If the phone hasn't been tampered with physically, it should be enough to just sync it without re-unlocking it, and it should be locked again.
Thx
I got a new one on the way. I didn't delete any files or regedit a bunch of stuff just a standard dev unlock and it started acting squirrly.

Help with Safe Mode? Broken Volume-Down?

So I have a galaxy s iii, att version, where I accidentally put it into safe mode, but in a dramatic turn of events, I seemed to have broken the volume down key... Idk if the volume down is broken, or stuck down, but now, every time I turn on the phone it boots into safety mode regardless of what I do. So far, I have tried:
Resetting the phone.
Holding Volume-up as I reset the phone.
Holding every capacitive key on the device except for the power button as I reset the phone.
I have also hit the Volume-down button like 30 times before resetting it.
I took out the battery to reset the phone.
I reset the phone with the battery out and plugged into a charger.
PLEASE help me find a solution. Im begging. Begging.
Typically, safe mode is achieved by holding one of the capacitive buttons add the phone boots up. Try rebooting without touching any buttons. And if the volume rocker is broken, look into a warranty exchange

Very strange behavior, can't reset, can't turn off!

I was starting to download some digital magazines I'd checked out from the library using the Zinio app. When I started, the screen flashed for a second and then the screen went black and the animated Samsung logo popped up like the tablet was powering down, or like you see when powering up. The only problem is that it's been that way for about a half hour now. It's not doing anything that I can see. I've tried to power down and it won't shut off. I've closed the magnetic cover, and it won't go to sleep. I've tried the volume up/power button reset, and that does nothing. I guess it's just going to stay like this until the battery dies completely. Has anyone ever seen behavior like this? Any ideas?
Thanks for any advice or opinions.

Try holding Power+Vol Down+Home at the same time. It should reset to the bootloader screen. Then you can press Vol down to reset the tablet.
Thank you for the suggestion. I'm back in business!
It did not reset to the bootloader. It just went dark and reset completely. No options or anything that I could see. Or maybe that's what you meant by the bootloader screen. Anyway, I didn't have to press any other buttons after holding down the Power+Vol Down+Home buttons for about ten seconds. It completely shutdown/rebooted and, once it came back up, everything seems to be fine.
Thanks again for the suggestion.

Samsung Galaxy A50 does not turn on after factory reset.

Samsung Galaxy A50 does not turn on after factory reset. Only from recovery. (Power and Volume up and select reboot). Do you have anyone similar problem please?
Factory Reset I repeated 2x. I did Wipe. I have also done the Software reset. I still can't turn on the Power button...
EDIT: When I connect charging, the POWER button works. However, the battery is charged at 100%.
EDIT2: The Samsung phone can only be switched on by double pressing the power button. First press: Picture of the round charge. Press the POWER button a second time after the picture goes blank. Now the phone goes on. Do you have it, too?
That's weird. I've never heard of that happening. I think you may have recieved a faulty unit.
