Lg optimus ls970 fastboot no power button - Android Q&A, Help & Troubleshooting

basucally flashed a rom and it went bad and my phone wont boot, i can only get it into fastboot but plugging it in and holding volume up and i have no power button, so i cant select boot into recovery, is there any way i can through the cmd?
*edit*
I figured out how to boot to recovery, download a recovery img, and in fastboot cmd you go
Fastboot flash recovery_image_name.IMG
Then
Fastboot boot recovery_image_name.IMG

Depends on which version of the official software/firmware you had installed. You might check out this:

If you were on a KK set up then that recovery won't work.

all i want to know is, when im in fastboot is there some kind of command line or any other way i can select recovery mode besides the power button? my power button is broken, and i cant turn on my phone to reboot into recovery due to me soft bricking it.

So when you turn it off, leave it set there for a bit (guess you would have to let it die at this point...), and hold Volume Up and plug in the USB cable to the PC - you don't get into Download Mode? But as far as booting to recovery without the power button and not able to boot into the OS...I can't think of a way. There are no fastboot commands to get to recovery and without it booting to anything but fastboot, there is no way to utilize adb commands either.

OK, with testing I found a solution for the problem
Here the steps what i've done:
1. Load the Flyer with the power supply unit.
2. From PC Commandpromt. Start fastboot flash recovery recovery.img. I've get the message "waiting for devices". I've used a old CWM 4 reciovery Image
3. Now connect the Flyer and Start with "Power + Down". Here was the surprise that now the Bootloop stops and i see now the Boot Menu. So I change here to fastboot and flash the recovery Image new.
4 Rebbot now an voila bo boot more and I can use the normal cwm recovery mechanism to recovery one of my old images... Perfekt

Somehow I Can't get to EDL mode

I just officialy unlocked my bootloader because I Can't enter EDL mode somehow. Tried everything, EDL scripts, adb, holding the volume buttons...
The phone always restart the the system (it works fine). This is weird because I can't do factory reset either, it always boots back into my system.
Can somebody help me in this?
If you have an unlocked bootloader, why do you need to go to EDL mode instead just use fastboot.
Care to explain better?
The issue is: I flashed TWRP with fastboot. When I try to boot into it (Holding Volume up + power) i just get back into system.
This is just weird, as I can't do a Factory Reset either!
Download edl7.zip file from xda thread and go into fastboot mode and double tap on cmd file...your device will go in edl mode (red led blink)

EDL is for flashing fastboot files for locked bootloader as flashing through fastboot doesn't work. If your bootloader is unlocked you can just use fastboot. For TWRP are you getting any error while flashing it, if not you should boot into TWRP by holding volume down and power button with your phone turned off.

Hey man. Thank you for your help. But I think that I'm not being clear on what my issue is. I have some experience on flashing twrp and rooting. But never faced something like this before.
I can't even do a factory reset (from the settings menu) as the phone restarts and just goes back to the system. I flashed twrp but when I try to boot into it I get back to the system. I try to reboot into bootloader via the update menu and the phone resets and just get back to system.
It's just as if I can't acess the bootloader menu at all.
That never happened, try holding volume button before pressing power button. You can also try it through adb, make sure you have usb debugging turned on. For fastboot use adb reboot bootloader and for recovery adb reboot recovery

Yeah, tried that too. This is just way too weird to be normal. I'm sure that I did everything right.

Stuck in recovery mode

I accidently flashed the lineage 16 recovery instead of lineage 17.1 recovery. I tried to install the 17.1 update through updater but my phone stuck into recovery mode. Neither I can boot into bootloader nor to android. I can''t flash anything. Power + volume down and connect the cable also not working to go into bootloader. Even bootloader option within the recovery also brings me back to recovery mode. ...adb devices command is also showing "device offline". Any help will be appreciated.
you should start from the beginning
is your bootloader still unlocked?

I can't go into fastboot mode. Is there any other way to check it?
Thank you @stukka2006 for replying me. I guess I saved my phone. So here what I did-
1. Extracted the stock firmware (Luckily I had one but can be found in the forum) and copied the dload folder to sdcard (as I was not able to access internal storage). (@stukka2006 your hint to start from the beginning)
2. Power off the phone and pressed Both volume buttons + power button simultaneously. After the vibration I left the power button while still holding both vol buttons till software update screen appears. But software update failed. So I just touched the reboot now option. The phone rebooted to fastboot mode.
3. I installed TWRP but was not able to reboot to recovery through commands and system reboot command brings me back to fastboot mode. So I again power off the device with cable connected and pressed both vol buttons. This time phone showed recovery screen (Should have worked with normal button shortcuts also, I guess) and I flashed the rom and rebooted normally.
Everything is working fine now except that I lost the data.
Happy you got all clear my friend !!!

You are quite lucky to have the stock ROM.

Build.Prop edit mistake

Long story short, I messed up and I regret it. I edited the SDK 2 API levels up to get an app to possibly work and didn't think of the consequences of everything else.
I was running 8.0.0 rooted and am unable to get into recovery as the main boot of android is messed up where all apps result in continuous errors and when trying to enable usb debugging in the settings, the settings crash.
If I could get into revovery mode, I can fix it. The issue though is holding power + vol down does not work. I am not sure how to get into the recovery when the v30 shows that conformity screen on boot when the boot loader is unlocked. I was able to get into fastboot mode but on that screen it says i need to enable OEM unlock. Sadly that is not working as settings crash when trying to enable.
Would anyone have any other ideas to get to recovery?
Let me know if any more info is needed.
EDIT: I do have LGUP installed and does see the device. I would prefer not to have to fully reset the device if possible. Can LGUP boot the device into recovery?
What you described (just holding power and volume) will not get you into recovery... the proper sequence (aka the "button dance") is more involved than that. If you're only holding down those buttons, then you're not doing the process... do a search to see what it is (I believe you need to release and then re-press the power button... but I don't recall, so certainly don't take my description as enough info.
You also said you can boot into fastboot - you may be able to "fastboot reboot recovery" to get into recovery... some phones respond to that.

LGUP can get you to Download mode but not Recovery.
You can boot to Recovery (TWRP) with hardware button dance.
8 sec Power + Vol-, and when it shuts off, release both, immediatly press both again (at the same time), and as soon as the LG V30 logo appears, release power and press/hold it again.
Should get you to the factory reset menu, confirm twice with "yes" (navigate via vol/power buttons), and TWRP should boot fine.
Might take a few tries to get the right timing for that

For that, remember the annoying bootloader unlock warning is part of the boot sequence, if you still have that.

@schwinn8 -
I ended up doing a clean flash with LGUP as I need my phone for work and thought this might as well be a good time to update from stock oreo to stock pie. I wish I had remembered the master reset method as that should have throw me into recovery, I was releasing and then holding both power and vol down when it should have just been releasing power and then holding while continuously holding vol down. Along with fastboot, a while back I had to reinstall windows and so not thinking things through, I did not have working fastboot drivers and didn't initially realize it.
Mistakes were made :/
I very much appreciate the reply.

How do I access download mode with hardware buttons in this device?

I tried going through recovery to bootloader, but that does not put me in download mode. Any other tips except Adb. Just thinking about what I can do in a boot loop or brick except wipe.

If you're in recovery mode, you can use ADB to command a reboot to bootloader, which for most Samsung devices opens download mode as well - the screen is just black instead of green.
Getting into bootloader mode via the buttons depends on the device, but the universal method seems to be this:
Power device completely off, wait a minute or two
Hold both Volume + and - buttons, do NOT press Power
While holding Volume buttons, plug in USB cable connected to your PC
Device should start in download mode.
If you press Power, or connect the USB cable before holding the buttons, your device will just power on.
Going into bootloader does not put me into download. I ahead to use Adb reboot download and you can’t use Adb in stock recovery
