One of my costumer V20 is now stuck in fastboot.
Whatever I do, it's keep coming back to fastboot mode.
I can enter download mode, and try flash , even using the costum LG up, with upgrade option, partition DL option.
I use Box ( octopus, Z3x ).
I don't know what is wrong with this phone.
it's only going back to fastboot.

Any help is really apreciated.
Thank You.

What does using the "fastboot reboot" cmd do ?

It is stuck in fastboot because your customer tried to root it with lafsploit without unlocking the bootloader.

They have two choices:

1 - Send it to LG to have it repaired.
2 - Wait for me to finish lafsploit 2.0 which will unlock their bootloader, and their phone will just start working.

The partitions that hold the unlock information are not touched when you flash a KDZ, so no amount of flashing is going to fix it.

I think that's what happen, and I don't have any choice except to wait . Returning to LG is not an option.
Thank you very much sir.

did you get to solve this problem also have one stuck in fastboot mode but no download mode
boot loader seem to be lock
If you cant get into download mode by powering off, holding vol up and then plugging into a pc (no power button needed) then you dont have a phone anymore. Unless rooted via dirtysanta which replaces aboot (which provides fastboot), the stock fastboot mode of the h918 can't actually flash anything to the phone which means no unbricking with it; TWRP and download mode are only ways to restore firmware.

This is a Magisk 20.2 issue there's at two threads in the LGV20 forum on how to recover

Sent from my LG-H910 using XDA Labs
