Is there some kind of hard (power) reset/shutdown method for this phone that I am just not aware of? This is probably the most infuriating phone I've ever worked with as it constantly wants to power back on even when it's shut down normally or when I do what should be a hard shutdown by holding the power button down. Makes getting out of a bootloop impossible until it finally decides to stay off.
Just one of the many reasons that I hate sealed in batteries.
I believe once or twice I have successfully held the power and down volume until it got me to the recovery screen when I was stuck with a boot loop or other non shutdown event.

Hold power and as soon as screen goes out release and hold Vol Dn, release when bootloader starts then use Vol keys to select shutdown and press power.

Well if I can get to the bootloader then mission accomplished, I've just never worked with a phone that will turn itself back on like this one seems to at least half the time. Holding the volume button down as soon as it cuts off seems to help send it to the bootloader if it does decide to power back on.
Yup... Should do the trick.
To be honest, in all the phones we have had there was never a way to force them off, except if it had a removable battery. Huawei, Moto, HTC, Samsung, Nokia... All would reboot if you held the power long enough.

can you get into recovery by holding the volume down button when the phone is off and then powering the phone up while still holding it down?
as long as it turns on and screen comes on, you are not bricked .. it's almost impossible to birck this phone ..
can't get into recovery at all, phone is not responding to anything just constantly stuck on initial white htc screen. have backup on sd though no way to get there through phone
how can pulling the battery not work? If there's no power to power up the screen it should die instantly
Try keeping it out for like 10 mins or more.
Then go to recovery and wipe/reinstall from backup.

And to get to recovery you have to start with the phone turned off (by pulling the battery). Then put in the battery and before you press the powerbutton, press and hold the vol- button down. When you're holding the vol- button, press powerbutton until the screen turns on, keep holding the vol button until you get into the bootloader just in case. From bootloader you can choose recovery with vol+ and vol-, powerbutton to select.
And as long as there's something happening on the screen (e.g. HTC logo) it's not bricked.
cheers Hawks556, all is good now
I feel like this is a stupid question, but here we go anyway. I'm on an LS980 with TWRP 2.6.3.4.
I can boot into recovery just fine, as long as I use adb reboot recovery, or any of the methods to do a reboot to recovery from software. For the life of me, I can't get the volume down + power key combination to work. This would be no problem, except I'm stuck in a bootloop (my own fault), and can't get to either the software solution or ADB.
Yes, I've followed the directions in which you hold the two buttons, and when the LG logo appears, release and repress them both. I've done this about a million times now, in every different pattern and length of delay I can think of.
If I hold all 3 during boot, I get the "hardware control" screen, with a barcode and my IMEI at the bottom. Download mode, using volume up + plug in USB, works as well. Both volume keys have been functioning fine for controlling volume in software, so they are mechanically sound.
Is there any reason the keys might not work during boot? Is there any other way to reboot to recovery? My only idea is to push the stock image to the phone in download mode, and re-root, etc.
Thanks in advance!
Start with the phone powered all the way down (if you're bootlooping, hold the power button for maybe ~10s until there's a short buzz from the vibrator and the LG logo pops up, then hold it down for a few more seconds to power off).
Hold power+voldown until the LG logo appears. Release them then immediately push them again, and hold for a few seconds.
You'll get a 'Factory hard reset' screen that tells you to press Power to confirm you want to do a factory reset. Push Power a couple of times to confirm this. If you have a custom recovery installed, it won't erase anything, it'll just boot into recovery.
I just tried this, and it worked the first time.
Antinorm -
I'm familiar with that process, and have been trying it nonstop! Here's a video; maybe you could critique my technique?
You don't have to hold both buttons after the release.
1. Hold VolDn + Power until LG Logo appears.
2. Release both buttons for a few seconds
3. Hold only Power Btn
4. You get into Hard Reset
5. Push Power Btn 2 times (For executing reset)
After that the phone will boot into recovery.
Don't do this with plugged in USB cable I don't know why, but it doesn't work if you have a usb connection.
Nope, no luck using just the power button for the second press. Thank you, though! I'll write some more detail of what I see.
Initial state: the boot animation is looping.
I press and hold the power button.
The screen goes blank. I continue to hold the power button.
The LG logo reappears for a moment. If I were to release the power button before this point, the phone would restart.
I do not release the power button; I continue to hold it. The screen goes blank.
I now release the power button. This is the phone in its "off" state. If I plug it in to a power source, a battery charge icon and a percentage is displayed center-screen. Entering download mode from this state works. The phone is not plugged in.
I hold the power and VD buttons together. I've also tried pushing one first, then the other, in either combination.
The LG splash displays.
I release both buttons.
I wait an amount of time. I have tried various values from "as quick as I can move my fingers" to "a solid three-count".
I hold either both buttons (pressing them simultaneously), or just power, and wait.
Time passes.
GOTO 1
Does any of that sound wrong?
Weird. This method works for me. But getting into recovery was a bit of a hassle for me too at the beginning. Your doing seems to be ok... well seems like your only chance is adb right now.

Do you know of any way to ADB without an OS booted or recovery? I don't!
IF your battery is low or almost gone - you can't enter in Recovery with those 2 buttons.
So just charge your battery. I'm using CWM 6.0.4.4 and phone charges battery in this mode. It's slowly, but at the end my battery was 100%.
Now I can go to Recovery with 2 button combo. No download mode for me, but I'll open a new topic for that.

Whelp, sorry. Would have thought you can adb while in download mode. Turns out you can't.
Well i don't have a better idea than you with going stock and start from the beginning.
Long press power button no longer works for us on the S5 to shutdown or reset the phone.
What to do if you're stuck in a bootloop and need to soft reset so you can get into recovery:
To get into recovery:
Long press power + volume down reboots the phone.
Wait for it to vibrate and immediately switch to volume up + keep holding power + home key.
Once you see 'Recovery Booting' (in dark blue, top left) release the keys.
To get into download mode:
Wait for it to vibrate and immediately press the home key + keep holding power + keep holding volume down.
Timing is a little critical but at least I don't have to pull the battery every time I get stuck testing something and want to get into recovery to fix it.
Ty sir, good to no.

Why is Sammy making it so hard for us to enjoy our phone?
Thank you for the 411 [emoji3]. I was wondering what was going on.

Thanks for this!
I actually just had this problem and had to phone a friend (switched to the S5 this weekend and ran into a boot loop problem while doing some of my final restorations... it's the reason they're last!).
Didn't do this exact thing as I had ended up pulling the battery out when the Power - Volume Up - Home combo hadn't been working for me. If it happens again, I know this is here!
I accidentally totally discharged my N4 and now t has been on recharge for over 2 hours.....when I turn it on now, the little battery displayd appears to be FULL.....BUT.....it does not start up like Normal. Is this Normal? Will it start up as it used to - after some more time? I HOPE so - this is my 2nd one.
Thanks, michael
Hold the power button longer, for about 3-4 seconds or hold volume down pressed and than press the power button. It should power on in bootloader mode, simply press power again and it should boot into system now.

I was having that problem too and remedied it by just pressing and holding random buttons down for random periods of time lol. Sorry it's not more precise. Eventually I had the power button held down with the volume up and it ended up turning on. Was down for a good like 2-5 min though with absolutely no signs of turning on.
Was only getting that problem after I selected oem unlock from dev options menu.
When it did turn back on, I powered down completely and held vol down with power to go into recovery and selected fastboot from that menu.

Yeah, thats what happened to me as well holding both Vol up and down with power. Now I either do vol up with power or vol down with power... never both haha. But I don't think vol up with power does anything.

for whoever has this issue and needs to see this, my steps to cut it back on (finally):
1. let it sit on the charger for like 5-10 minutes
2. unplug let sit again for a few minutes
3. pressed power and both volume buttons till i felt a buzz and it cut right on.
