How To Flash/Install

For TWRP recovery you will need to download the TWRP H870 image from the button below:

Download TWRP

Reboot into the bootloader by following the command

adb reboot bootloader

Flash TWRP recovery by the following command. Replace the red words by name of recovery.

fastboot flash recovery twrp.img

For TWRP to “stick” you must 1st boot into TWRP and not boot back into Android until after doing one of the following…

flashing SuperSU/Magisk
deleting the recovery-from-boot. p file from the /system directory
flashing the no-verity-opt-encrypt-4.1 or android-boot-repack zips

After flashing TWRP unplug the USB cable and power off the phone. Then boot into recovery which should hopefully load TWRP.
To boot into recovery:

Using 2 hands.. use one hand/finger to press/hold volume down.. and use the other hand for the power button. Press n hold both buttons.
As soon as you see the LG logo on the screen. Let go of the power button then quickly press it again (never letting go of volume down).
Keep holding until you see the Factory Reset screen. Click through the factory reset screens using the volume buttons to move up/down and the power button to select. Choose “Yes” twice until it boots into TWRP recovery. Despite what the screen says it won’t actually factory reset/wipe your data… as long as you’ve installed TWRP. If stock recovery is installed it WILL wipe data.
Now you can flash your root zip of choice. You will not be able to decrypt your internal data while in TWRP since decryption for the most recent LG devices has not yet been added in TWRP (unless performing a full /data format in TWRP.. not recommended unless you prefer your data unencrypted) but you can:
Use an unencrypted external sd card to throw the files onto
ADB push the files while in TWRP to the /tmp directory
use ADB sideload in TWRP
