How to run TWRP Recovery on LG G4 H815 - on LineageOS 14.1 / Android 7.1.2

[xzenx1234x]

I am turning to the esteemed community of Xda with a request for help.

I need help booting the TWRP IMG image - using Minimal ADB and Fastboot 1.4.3 on Microsoft Windows 11. It says this phone was Android 6.0. and TWRP Recovery in the latest version available. After successfully flashing Android 7.1.2 / LineageOS 14.1 - it tells you that when you try to boot into TWRP Recovery - from the Power and Vol Down hotkey - how to say. My phone is in erase mode. I inform you that my phone accidentally erased probably TWRP Recovery - which was on the partition.

This phone has an unlocked bootloader.

Dear community, can you help me?

I kindly ask for help. I need to establish communication via Minimal ADB and Fastboot - with the LG G4 H815 device.

I kindly ask for help.

Sincerely, Xzenx1234x

do you know how to enter fastboot mode? is fastboot devices successful? just install TWRP recovery again same as last time?

Hello, I did this on Android 6.0. Now I have Android Android 7.1.2 and to be honest I'm lost with it. Because the guide for Android 6.0 that I used on XDA - said to rename the TWRP.img file. So I did it. Now I don't know if I should rely on the guide made for Android 6.0 - or should I look for a guide for Android 7.1.2 - that is, for LineageOS 14.1?

Answer the first question. Yes, I know how to enter Fastboot Mode from a hotkey. The hotkey worked on Android 6.0 I chose this hotkey on Android 6.0. In Android 7.1.2 - it starts to have Wipe Mode.

So the answer is NO. Usually one can enter fastboot mode with Vol + Pwr when device is powered off. according to this link it's Vol Up + USB cable in your case.

you can however reboot into fastboot mode from adb

adb devices
adb reboot bootloader

if fastboot devices shows phone serialno you are in fastboot mode ready for flashing.

fastboot devices
fastboot flash recovery twrp-3.2.3-0-g4.img

Note: after flashing, reboot straightforward into recovery mode (Vol Dn + Pwr) otherwise TWRP recovery will be overwritten from LineageOS recovery on startup.

use older TWRP version for best compatibility with Android 7.1.2

You say you are already on LineageOS, therefore it's very likely the bootloader is unlocked already. so all it needs is enter fastboot mode, double check installed usb drivers for Android Bootloader Interface (yes, that's different from ADB) and flash TWRP from fastboot...

He is well known in the g4 forums since several years. Atm I'm aware of at least 3 accounts by him. He usually (re-)appears after months of silence and spams TG and xda with his "incredible sincerely" requests. For several reasons we had let him ban multiple times from xda @sdembiske knows what i mean
But even I sometimes do not recognize him and find me answering on stupid and already answered questions or well documented topics

so now.. that child already signed up with another account and won't read the guide it was desperately begging for?
