TWRP install fails (EU Version) - LG G6 Questions and Answers

Hi everyone,
I'm trying to install TWRP on a fresh LG G6. I before updated the G6 to the latest available version.
So its currently running Android 8.0.0
Build Number OPR1.170623.032
Software version V20a-EUR-XX
I already unlocked the bootloader. Then I bootet into fastboot and tried to install twrp-3.2.1-0-h870. But after rebooting it with Volume Down + Power Key and reseting the device. I only see the TWRP splash screen after that the phone is booting the normal way up (and is reverting the bootloader).
I then installed (also via fastboot) twrp-3.1.1-0-h870. With this version I'm able to get into TWRP but this version is asking me for the password of the partition to decrypt. I didn't set up any encryption. So i tried "0000" --> no success. I also bootet andoird normaly and then setup a display lock screen with Pin 0000. But this code TWRP also refuses to use.
So I'm a little bit stranded here because I don't know what to do next.
Does anyone have a idea?
Greeting Uwe

You need to skip the password stage then format all. Type yes then it will work fine.
When it asks for password you can skip this stage

If I do so. I get
Formatting Data using make_ext4fs...
YOu may need to reboot recovery to be able tu usw /tada again.
Updating partition details...
Failed to mount '/system' (Device or resource busy)
... done

Click to collapse
Then I hit reboot and the device is rebooting into Android and starting the first startassistant (so the format finally deleted something )
Then I power off the system and reboot with "Volume Down + Power" and I again only end in Factory reset data dialog
Ok next try same procedure than above. But not reboot into system instead only reboot into recovery --> pushing lineageos and the other zips onto the /sdcard/.
Wiping system, data, cache.
Flashing twrp via twrp, flashing lineageos, flashing gapps, flashing lineageos su package.
Reboot
And I'm greeted by Lineageos. Thanks for your support.

OP2 soft bricked, can't access recovery, not recognized by laptop

Hey,
Very strange query but here goes. Rooted phone a while back and installed CM13 along with recovery. Was trying to update TWRP{ by downloading .img from their website, went to flashing, selected the file and hit recovery. Said it was succesful so attempted to reboot. Plugged in to charge and was charging but when I tried to switch it on, it was stuck in Cyanogen Bootloop (blue alien stayed on the screen for 10+ minutes). Tried rebooting to recovery by hitting power + volume down and instead of booting to TWRP, it takes me to a Cyanogen recovery screen where I see the following options:
Cyanogen Recovery.
- Reboot system now
- Apply update
- - -apply from ADB
- - -choose from emulated
- Factory reset
- - -system reset
- - -full factory reset
- - -wipe cache
- Advanced
- - -reboot recovery
- - -reboot to bootloader
- - -Wipe system partition
- - -view recovery logs
Here's what I tried as troubleshooting. Tried to do a system reset, factory reset and wiped cache and tried to restart my phone but no luck. Still stuck in boot loop with CM logo. Tried to reboot to bootloader but the screen is stuck with the 1+ logo for about 5 mins so gave up on that.
Basically, right now I can't access anything on the phone, can't find any way to reinstall a ROM and when I plug it into my Macbook, it is not recognised. So I'm screwed sideways. I had TWRP recovery set up so I have no clue how this happened but can anyone please help me with this.
If data isn't at risk try the Qualcomm recovery tool one the oneplus forum it's by nammand bhal (definitely butchered the name) but all data is lost and resets the phone to out of box conditions locked bootloader and Oos 2.2.1 so this is often a last measure (tool is Windows but may have Mac variant and the file is quite big)
My suggestion is to try to boot to bootloader again and flash TWRP
hmm mac book I don't have much experience with those
If you have a Windows pc you can use adb or on Mac if it has it. Also when it come to being found by a computer in recovery it should but again don't have a mac
CM13 replaced your TWRP recovery with Cyanogen Recovery.
Try to boot into fastboot by holding volume up+ power buttons. If successfull, flash TWRP Recovery, boot into it, wipe everything and do a clean install of the ROM.
Macbook won't detect your device unless it is booted up, in recovery or in fastboot mode.
Doesn't it detect while you are in CM Recovery??
Try selecting Apply Update and Update from ADB. It should detect the device atleast now. If yes, try sideloading.

I knew I would regret getting that macbook at some point
Borrowed a friend's PC and was able to flash TWRP recovery. Was then able to boot into it and do a clean install. Ended up installing Oxygen OS this time. Do you know why this issue occurred so I can research how to prevent it next time.

Actually I don't think the issue was with the Macbook since I have unlocked, flashed custom recoveries and sideloaded ROMs on several devices including OP2, OP3, Nexus 5, etc on mine. It might have been some accidental flashing error, which unfortunately ended up bricking your device.

Not booting into TWRP

Hey everyone,
I decided to root my lg g6 and got a fickle. After unlocking the device and flashing TWRP I tried to boot into it (''adb reboot recovery'' command) and it deleted all data and then twrp shows on screen for a split second and almost instantly boots normally into android so I set it up while still being unable to access twrp and any of it's functions. Does anyone have any idea what could be the problem?
P.S. Of it helps: before that i had a problem that every time I tried to use the ''adb reboot recovery'' command the console said ''no devices/emulators found''. After a couple tries I wanted to check whether the phone was connected just to make sure (''adb devices'') and after that it worked and I ran into the problem above.
Thanks for all the answers
When you first unlock BL and flash recovery you have to manually enter recovery mode.
Hold power and vol down till it turns off. Hold same buttons again until you see lg logo. Release power and press and hold again.
Then ask you to wipe etc hit yes both times and it will boot to twrp.
I tried that but it still doesn't go into twrp. After confirming that wipe stuff it just boots into android (without wiping)

You have to flash TWRP recovery and when it complete then use the button combo to boot into twrp, otherwise it will boot and restore the recovery.
flash twrp
button combo to twrp
done
Yes I've done that but the problem still exist.
btw thanks for the help
Maybe try fastboot flash recovery recovery.img
Try the all-in-one tool on this forum
By the way, I am running into the same issue.. I have a LG G6 US997,.. I have tried installing TWRP unofficial ones so many times and every time i manually try to access the recovery.. the phone simply wipes all my data to default
Hello,
I have the same problem. Did anyone figure out how to solve it? I'd highly appreciate any help.
If I try to boot into recovery, it asks me to factory reset, i hit yes twice and then the phone just goes on to boot normally. The data is not wiped but I can't get into TWRP.
If I enter "fastboot reboot recovery" after flashing TWRP it returns "fastboot: usage: unknown reboot target recovery"

Can't access Recovery, only fastboot and the universal bootloader, please help!

So after stupidly trying to update twrp through twrp instead of fastboot, I can only access fastboot and the universal bootloader installed on the phone. If I don't do anything, the phone simply goes through universal bootloader and I see a small penguin before the screen goes back and I need to restart the phone again. However, in the bootloader I can select to go to fastboot which does work. I've tried flashing TWRP through fastboot (fastboot flash recovery twrp...) and it said success however after clicking 'reboot to recovery', the phone once again just boots to the bootloader and I'm back at square one.
Thank you so much if anyone can help!
FYI, you can update TWRP using TWRP. Nothing wrong with that, I do it all the time. It's faster and easier to do so.
You might have an incompatibility between bootstack and TWRP.
So, please provide us more info.
ROM:
Bootstack used:
TWRP version:
What were you trying to do besides updating TWRP?:
Funny thing... I'm having the exact same problem.
I instaled TWRP (3.1.1-0-9c3b7e99) using the AxonToolkit 1.2.1.
Everything went smooth with the toolkit. I could get into TWRP and did some back-ups (as recommended), then wipe Dalvik/ART Cache, System, data, cache, and finally, try to install LineageOS 15.1.
I used the files:
- ZTE_A7LOSv1_UniversalBootStack.zip
- A2017U_OreoModem.zip
- lineage-15.1-20180810-UNOFFICIAL-axon7.zip
UniversalBoot and Modem were installed correctly, but I got an error when trying to install Lineage. I can't remeber the error number but it said something like: "this ROM is for device ailsa_ii_axon7 but this device is ."
Since then... my phone is in eternal loop and can only get into Fastboot. Can't access TWRP.
Thanks in advance to anyone willing to help me.
Don't mind... I have it back.
After many reboots, It only seems that this is working different with the Universal O bootloader. On the main screen, I tap the volumen button, choose "Recovery", reboot, press the power button on the main screen, press it again, the Linux Pinguin appears, press power button again, and then TWRP is back.
After that, I got to wipe and do the normal ROM installation process.

[SOLVED] Unable to enter TWRP/Stock recovery and can't boot into system

Hi,
I have been using my P Smart (FIG-LX1) for a while with LineageOS 16 and decided to move on to Android 10. Installed LineageOS 17.1 (found it on this forum) and pph-Magisk 20.3 for root - it did work, but the system was unstable so i decided to try AOSP 10.0 instead. I entered TWRP, wiped cache,dalvik,system and data, flashed the ROM, gapps etc. It was advised to now flash stock recovery and use it to do a factory reset - and now i'm stuck here.
After flashing the recovery_ramdisk img the phone stopped being able to enter any recovery at all. The system itself does not boot (stuck on the "Your device has been unlocked (...) Your device is booting now..." screen forever), the recovery never appears (previously in the start screen with 'unlocked device' warning it used to suggest pressing volume UP to enter recovery, now it only shows "Your device is booting now"). As i can still access fastboot, I tried flashing TWRP again - the TWRP splash screen does appear, but the phone gets stuck on it. Also tried flashing another system's img - nothing changed.
Is there anything I can do or did i just brick it completely?
Thanks for help!
SOLVED:
Apparently running fastboot erase on system and userdata partitions made me able to boot into recovery/erecovery again. I do have another problem now, but it's not connected with this one so I will create another thread for that.
Could you try help me? I can't even get ADB to work anymore

Phone bricked after installing LinageOS 17.1 - System UI Crashing

Hi,
Today I tried to install LinageOS 17.1 on my Huawei P10 lite (at start, still completely Stock Rom).
Unlocked bootloader following procedure in https://forum.xda-developers.com/p10-lite/how-to/p10-lite-bootloader-unlock-june-2020-t4113315, worked great.
Installed TWRP following https://forum.xda-developers.com/p10-lite/development/recovery-twrp-huawei-p10-lite-t3953890 ; also here, no problem.
Then I tried installing LinageOS following this thread https://forum.xda-developers.com/p10-lite/development/rom-lineageos-17-1-huawei-p10-lite-t4064115 . Here I ended up with the Linage OS System UI that constantly crashes, restarts, crashes again etc.
This problem is mentioned in the same thread but none of the solutions seems to work for me.
I tried to downgrade the TWRP to the older 3.3.1 and then redo the entire installation procedure => No success
Then I tried wiping and formatting all the caches/data that was mentioned during the thread + re-executing the entire installation procedure => Still no success.
Can anyone help me?
What could also be relevant:
In TWRP I cannot seem to copy data to the device, whenever I try to do that via the File Manager (I am using Linux Mint 20) I can see the device and its internal storage but transferring data is horribly slow (it would take 5 hours 45 minutes to transfer a 3 MB file) or just fail. I also tried this in a (virtualized) Windows 10 installation with the same results.
When earlier today (before having installed LinageOS) I tried to transfer files, it worked very well. Also, I tried it with multiple USB cables just in case it might have been a faulty cable.
Pushing a file via adb push doesn't work as the device shows up as "unauthorized". The installation of the patches (magisk, los_patches_warsaw, opengapps etc.) I did using ADB Sideload which seemed to work nicely as well - really making me thing that the USB transfer issue is not hardware-related...
Furthermore, I know this is a noob question but anyway: the procedure says "flash los_patches_warsaw.zip". How exactly should this be done? Copying the file to the internal storage from a PC (which I cannot do, see above) and installing it via TWRP Install? Flash via Fastboot (to what destination)?
Tx in advance!
I've had this issue as well, what I did was disabled dm-verity and forceencrypt using https://forum.xda-developers.com/android/software/universal-dm-verity-forceencrypt-t3817389 after flashing system in fastboot and then I flashed los_patches_warsaw.zip from SD Card (MTP is broken in older twrp, use 3.4.0, also try this at your own risk).
Thanks. I solved it in another way meanwhile.
I reinstalled the stock recovery (which I was able to do by choosing the E-Recovery option in the "your device's bootloader has been unlocked" screen after startup. It reinstalled the stock recovery and ROM.
After that I installed the image from OpenKirin (it didn't need TWRP - even more, only the stock recovery is supported if using OpenKirin), and then it worked like a charm.
Just one thing, I cannot find how to update the OpenKirin installation except for flashing it via Fastboot (no option to auto-update). I wonder if it is even possible?

I think it's only possible by dirty flashing it, also a little correction for my last post, I meant internal storage not micro SD card.
it's a shame the original LOS 17.1 thread is closed.
My experience with WAS-AL00 (china version) on macOS:
After I flash LOS 17.1 ROM, "fastboot reboot recovery" doesn't reboot the device into recovery. Then I unplug the phone, and reboot into system, I came across system UI crashing constantly. After managing to get through to the main screen. Plug the phone, "adb reboot recovery", then flash los_patches_warsaw from microsd card (you need to copy the file to a microsd card and insert it into the phone). Then reboot system, this time the screen is black. only long press power button show three options "power off", "restart", and another one i don't remember. @KinteLiX 's method didn't work for me.
Then I tried stock recovery with openKirin (worked), Twrp 3.4.0.0 with openKirin (also worked, even though they state that only stock recovery works with their ROMs).
Last I tried twrp 3.4.0.0 with AOSP 10 from @DarkJoker360. It works.
Note: after flash the ROM, power off the phone, and long press three buttons volume up, volume down and power at the same time, and you will boot into twrp. If it shows update fail, then reboot and try to get into erecovery and wipe data/factory reset and then power off, long press three buttons simultaneously and you will be able to boot into twrp, if not, wipe data/factory reset again in erecovery (I accidentally found out about this. before this I was unable to boot into twrp after flashing any ROM, "fastboot reboot recovery" doesn't work). then do as the thread shows.
update: making a call doesn't work with AOSP 10 on my device.
The system crashing should come from the integratet AOD overlay....there should be a solution to solve that issue but i didnt rember the correct way how to. Just search in the p10 lite forum here on XDA.
