Hi, I'm trying to do oem unlock. But I have problem where after phone reboot to bootloader I see how phone behave like some volume button is pressed. So if I press volume button to select any thing then only down button will to stop cycling (only when pressed), up button do nothing. Power button stops cycling (only when pressed) but I can't select any thing. I can do "fastboot oem unlock" which switch me to screen where I'm supposed to select "unlock the bootloader" but due to constant current menu switching I can't.
Only thing I can do is "fastboot reboot" back to android where buttons are working fine.
Do you have any idea how to stop this menu cycling in bootloader? Or is there some way to installation of LineageOS entirely through the Fastboot or the Adb command line interface?
So I solved by hard reset (factory reset in android options) of device. After then bootloader menu works correctly.

i just read this on a site its for hard reset but cant you get into recovery mode with it
Hold the Volume Down button and press and release the Power button. A window with some option will be displayed on the screen. You can use the Volume Up/Down buttons to scroll between these options. The following options are present to you on the screen: Fastboot, Recovery, Clear Storage and Simlock.

Not working on my device, which also doesn't allow 3 button recovery ㅜㅜ, you got my hopes up for a sec though.
I tried to unlock the bootloader on my OPT, after I had already unlocked and locked it. The phone does not start when i hold the power key, it does not start recovery when I press and hold the volume down and power key. It starts in fastboot mode when I hold the volume up and power, but when I type a command in cmd is says that the device is not unlocked and the command failed.
When type "fastboot reboot" it shows the oneplus logo and the "powered by android" and after a second, black screen, nothing.
I will appreciate it if you could help me....

It's not adviced to relock the bootloader once you already unlocked it.It can cause strange issues.

Hey guys. I just got LG G6 H870 model. Unlocked bootloader without much problems, but issues came later. While being in bootloader I can't do anything, hardware buttons seem to not work. The only way to get out of bootloader is to use "fastboot reboot" command, but that prevents me from getting into custom recovery after flashing it. Only entering download mode works (holding volume up and plugin in usb cable). Non other key combination work until I boot into system.
Can this issue be somehow resolved?
I had similar problem myself with entering recovery more and the reason behind it was that I didn't press the button combo in proper way. what you actually have to do is while you in fastboot mode you press down and hold power button and volume down button. phone reboots after a moment and you should still be holding these keys and when lg logo appears you let go of power button for brief second and then press it back again and then when a prompt on white screen appears just go yes two times and phone shall boot in recovery mode . I had watch a tutorial movie to figure that out. other easy way is just to have adb enabled and reboot it with adb reboot recovery command via USB cable

No, because I had G5 and I know the proper way to do that. Problem is I can hold the power button as long as I live and the phone won't reboot, regardless of pressed combination or power button solo.
and the adb command way ?
Well... Nevermind, turns out vol down button isn't working at all.
still good way around is adb reboot recovery
LG G6 H871 unrooted
I just can't get into fastboot or recovery mode. I've tried everything on the internet.
I've tried turning off the phone. Holding down the volume down button and then plugging in the USB cable.
I've tried adb command "adb reboot bootloader" which just reboots the phone until I can see the "enter your PIN" screen
The closest I got to the recovery mode was using "adb reboot recovery" which gave me the "no command" screen.
Any tips on this?
Have you enabled OEM Unlock option under Developer settings?
Yes. "Enable OEM unlock" and "USB debugging" enabled.
both oem unlock is on and usb debugging on and my computer has accepted the fingerprint from teh device to shake with adb. . still cant get into fastboot mode.what to do.
Is your phone rooted? If so use flashify to reflash recovery. You do know that if you want to boot in recover you have to let the power key go and repress it once your screen goes on right?
You can also try phone off. Holding volume up while you insert usb cable. Might be a tool that allows a command to be send to reboot it in fastboot mode? If not downgrade its firmware..

If I understand correctly, when you got to the No Command" screen, you were actually in Recovery. From my experience, the No Command screen is like a "greeting", if you will. Once you see that screen, you need to fiddle with the power & volume buttons. I believe the correct combination is to press and hold the power button. Then press and release the volume up button but continue to hold power button. If that is not the correct sequence you will need to Google for the correct order. Reference.
Considering that you are not rooted, there is not much you can do in the stock recovery.
EDIT 2 - Realized that this thread is over a year old and the OP has probably moved on. Didn't realize another member revived it. Sorry.
OK, there goes a big problem, I believe that my volume button - is broken and ends up being pressed constantly, so the phone goes straight into fastboot, I have tried several commands like fb-mode-clear, reboot-bootloader ...
nothing went right, i would like to know if it is possible to disable the physical buttons via fastboot for it to boot normally....
Or some command to enable USB Debugging via Fastboot;
additional information: bootloader blocked.
Now you broke de button, you are stuck Butrón

You are not able to change anything with a locked bootloader. So you can't modify/disable the hard keys.
USB debugging in fastboot mode is not possible.
The only way to fix this is to repair the key.

I managed to turn the device on once and enabled usb debugging, is there any way to disable the volume button (-) via command or TWRP?
To boot up your phone you must press+hold Vol +, too. This combo creates a bugreport and let your phone boot normally.
When I press and hold the vol- key on my Moto I can still use it as I always do except from locking it.
Try to remap your keys by installing the app "Button Mapper: Remap your keys" (by flar2). It's available in the Play Store and runs without root permissions.
