[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.

[Q] Nexus 7 will only boot through bootloader menu

Hi all,
My new Nexus 7 (2013 model) arrived today, and it seems that it can only boot up through the bootloader menu, i.e. the power button does not work properly. When plugged in, the battery charging icon does appear for a few seconds before disappearing.
The problem is that holding down the power button does not turn the device on. Holding down volume down+power button works correctly and shows the bootloader menu, and from there selecting "Start" is the only way to actually boot the device. When plugged in to a power source (outlet or computer), holding down the power button causes the battery charging icon to appear, disappear, and reappear constantly. Holding down the power button when unplugged shows no response on the screen, even after holding down for a full minute. Once the device is booted, the power button works perfectly for locking, unlocking, and showing the power off menu.
I already tried doing a factory reset, which did not help at all. Is there anything I can do to fix this problem?

Your best bet is to ask in your device's forum section as this section is for the 2012 version.

OnePlus Two boot issues

Hi guys,
I've got some problems when trying to boot my OP2.
First of all, my phone won't power on when holding the power button. There is no reaction from my phone. When connecting to a USB port of my computer, the phone will power on showing the battery charging indicator. I tried several things:
- Power cycle: holding the power button for 20 seconds 5 times
- Holding the power button when connecting my phone to my computer: the OnePlus and Powered by Android logo, after a few seconds, battery charging indicator comes up
- Holding the volume down button when connecting to my computer: the phone is stuck at the OnePlus logo and Powered by Android logo. I have to disconnect the battery to turn off the phone. (Yes, I opened my OP2)
- Holding the volume up button for 20 seconds when connecting to my computer: no reaction, phone stays off.
Yesterday when holding some buttons, I ended up on the fastboot screen, but I don't know the combination of keys and duration to end up in this screen. When in fastboot mode, is it possible to reset this phone, because I can't open recovery mode (volume down button)? And how to I enable fastboot mode?
Might this issue be caused by a broken battery or another hardware issue?
Thanks in advance XDA-hero's!

(Solved) Right way to simulate a battery pull?

Is "power + volume down" is the way to simulate battery pull like other phones?. I tried it but it does nothing but making me press power buttom twice to start device.
Any info about this? or zen5 does not supported? I nearly can't find anywhere.

All I know about Power + Volume Down is booting to edl mode/download mode or something similar to that. I use Power + Volume down to reflash clean bootloaders using xFSTK (Fixing bricked Zen 5's). If you delay pressing volume down (pressing power first and press volume down as quick as you can before it vibrates) you can reach recovery mode. I think there isn't 'any simulating battery pull' in Zen 5. Only force power off. CMIIW

@ezrawk Got it! Thanks for your explaination.

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.
