TWRP install on G4 H815 20A mm, doesn't stick (unlocked bootloader by LG official)

Hi,
I get TWRP running on phone , but when I boot into recovery , I always get the Standard Recovery, only option being a factory reset. Have opted for this factory reset and that is exactly what I get, no TWRP :crying:
Thanks

Also if you reboot to recovery through TWRP itself, it won't stick? If not: Is rooting an option for you? If yes: Try Flashify and flash it through this nifty little app .

I did have Twrp running on this phone but had to reinstall the full 6.00kdz to get out of a bootloop and since then TWRP won't sick.
thanks

More than one way to skin a cat. went HERE chainfire Systemless Root 2.61 using Running TWRP from PC
Update on getting TWRP to stick. ......... I had success using following

When done, execute “fastboot reboot”

This happened to me, too. Here is what i did:
Boot your device into fastboot mode via adb, straight up boot to recovery ("fastboot boot twrp-2.8.7.0-h815.img"), transfer the recovery image to your device, then flash it from within TWRP (there is an option for that within the normal install menu, its called "install image" or something like that). Hope this helps, it did for me.
Edit: Just realized you already found a solution. Never mind.

Ive the same problem. I unlocked the bootloader by the official procedure. Then i tried to flash twrp but it doesnt install truly. It always appear the stock recovery. I tried also clockrecovery but nothing. No recovery wants to get installed. Pls help me i want a custom rom on my g4

use twrp v2.8.7.0 on 20A mm....... adb reboot bootloader, fastboot boot twrp-2.8.7.0-h815.img, and to double check you have recovery,adb reboot recovery and then flash STOCK-20a-ROOTED

you can upgrade twrp with the twrp manager from playstore (once youve got twrp and root of course)

Can you give a try to nodded twrp and one more thing mount system before flashing any ROM.
Note: after decrypting if you want too boot into OOS you need to Flash SuperSU or otherwise the OOS will force encryption and that may create problem.

okay now after few trial and error method i have come to the conclusion that this happens only after unencrypting the device. after eunencrypting it wont boot any other roms except those which have been already backed up.
So,
can i flash roms on encrypted device? I mean i test a lot of roms and i change frequently.
I guess no, right?

Yes try with encryption as the ROMs doesn't require decrypting the device. Decrypted device is only required if you want to use multirom.
Good Luck.

TWRP recovery loop, what should I do?

Hey all. I got my mi6 recently. and I installed twrp on it, and flashed magisk. I was trying to install atmos in recovery mod, then I remembered that I hadn't already downloaded the file. For some damn reason I decided to wipe my device. however that didn't go well, and now I'm stuck on a twrp load loop.
I've already tried this command unsuccessfully.
Code:
dd if=/dev/zero of=/dev/block/bootdevice/by-name/misc bs=256 count=1 conv=notrunc
Also in desperation, I flashed my phone, rebooted it and etc.
What else can I try?

you can re-flash Twrp in fastboot mode, then boot to twrp, connect to you pc, it will recognize your phone as usb storage.
Down load you rom, copy it to your phone, then install rom by Twrp.

Can you boot to TWPR ?
- Yes: you can connect to PC and copy your rom, then install
- No: flash fastboot rom: download from Xiaomi site, use Miflash to flash in fastboot, then flash TWPR again.

you may need to use a mobile browser. But there are mirrors.

I managed to fix the problem, by accident.
I just wiped Dalvik cache and data using the wiping tool in twrp.
after the reboot, TWRP was gone, and a fresh rom was installed with all my data, gone. However, that already has happened. So it wasn't a great loss.
I'm not technical, so I don't really know what made caused the loop, or how another wipe fixed it. So if anyone can explain it better, the floor is yours.
Thanks for the support.

I am unable to flash a custom ROM on my note 9 pro (joyeuse), I tried xiaomi.eu, havocos, evolutionx, lineageos, etc.
Also tried every possible recovery, no matter what I do when I hit system reboot, I land on the fastboot screen.
Followed the procedure, format data, wipe dalvik/cache tried disabling encryption, flash magisk, I'm out of ideas.

Logs would help.
Or even screenshots of any errors.

Follow rom install guide to the letter (and no extra steps either). If unsuccessful ask in the rom thread. You didn't have to open a new thread mentioning all these roms. It's hard to help you because each rom has a different procedure.

I've already tried everything.
Either bootloop or fastboot screen.
I followed the instructions exactly.
I would like to install Lineage-OS

After installing TWRP are you immediately and succesfully rebooting to TWRP recovery before doing anything else? - if you do not do that, then you can end up back at MIUI recovery.

No need use recovery, Just download this gsi rom（https://sourceforge.net/projects/he...5011-HBTRIA-10-12-2020-GSI-Aonly.7z/download） and extract the 7z file, rename the extracted rom as system.img ,and type in fastboot cmd:
fastboot flash system C:\system.img, Which“ C:\system.img ” should be replaced by your rom's directory.
for powershell type .\fastboot flash C:\system.img
then fastboot reboot

I do not trust myself.
The last time always bootloop.
Can someone give me step by step instructions.
for example:
1. Wipe ...
2. do not Format ...
...
F**k off
Mi Recovery again.
