I think you can get to Download mode by holding both volume keys simultaneously, then plugging a usb cable. Can't verify that right now but maybe then you can use adb or fastboot to reboot in normal mode (adb reboot or fastboot reboot)

[Q] Recovery's fine... VolDn+Power doesn't work

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.

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.

turn off on a brick phone

my OP6T is bricked and I have to turn it off to repair it with the volume + - command.
How do I turn it off? There is a special combination of buttons?

Hold volume-up, volume-down, and power buttons simultaneously. After a few seconds, it should reboot. Immediately after rebooting, hold volume-down and power buttons to get to recovery. Select power off in recovery.

I already tried but when I press turn off it has put the recovery mode back and now it's bricked on the screen where there is the message that says the phone is bricked.
Thanks anyway.

I just went through this same thing last night with my OP6. Make sure the device is unplugged from the computer, or any other power sources. Select Power Off and immediately hold the volume + button for 5 seconds and while still holding volume + plug it into your PC.

It's okay I turn off and my phone is good now.

Phone won't turn on after battery died, using ROM

Hello, I have been using the Pixel Experience ROM, but earlier today my battery completely died. It then shut down, and now even though it has been charging for quite a while it won't turn on. First, when plugging it in I saw that charging percentage, but when I tried to turn it on it just went black and won't turn on even when pressing all the buttons for long...
Do you have any idea can this be fixed and how would I do that?
Thank you so much for any help

6T Key Combinations:
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
Try holding the Volume up and Power for several seconds. Do any of the other key combinations there work? Remember on the MSM Tool one, the screen will remain off / blank, only the MSM Tool will recognize it.

Unfortunately none of these work. I already tried them. It doesn't heat up at all while charging, so it seems like I can't get it to charge at all rather than there would be a problem with the system etc. would even MSM work if the problem is that it doesn't charge and it has no battery at all?
Do you reckon it is due to no power or a fault in the system? I really can't do troubleshooting on this level myself!

I wasn't necessarily recommending using the MSM Tool to flash the phone, just to see if there were any signs of life. You can plug it in, use the tool just to see if the PC recognizes it, without hitting the "go" button.
