My device isn't supported by twrp (Huawei fla-lx1 or fla-l21) and I want to install this gsi image file because my phone is treble compatible, is it a must to have a working twrp image? Doesn't LOS has its own recovery thing? Can I still root it and install modules? Can I do ANYTHING?

Once you can unlock bootloader then you could do a step further, GSIs can be installed through fastboot, and in regards LOS recovery it must there one specific for your device, they're not generic recovery images for every android device.

Ultimate Guide for Flashing GENRIC SYSTEM IMAGE.
Contents:
Intro
how to flash gsi.
how to get rooted.
gapps issues
how to get back to non treble rom from gsi or treble enabled builds.
Introduction and basic information:
GSI means Generic System Image, which can be flashed over any Treble Device.
So, in simple words : same System.img can be flashed over multiple devices having Treble Support.
This happens as we now have a separate /vendor partition where all the vendor hals are stored.
Now, this will help to do easy bring ups, Treble builds are smooth af y'all know that and you'll get to flash aosp treble rom
Also, if you own 2-3 treble devices, now you'll just have to download one system.img xD it'll work for all of em ( if treble supported )
How to get Treble Support?
Flashing Treble TWRP won't give you treble support. Keep that in Mind. It'll just mount the partition in the recovery, so that vendor img can be flashed.
To get Treble Support, you'll need to flash a latest ROM which has vendor image compiled with the latest changes by mikeNG, once you flash such a ROM, you'll get the vendor stored in the vendor partition, and after that you can flash any GSI ( as it's just System.img, and all our device specifics are in /vendor so it won't mess with that)
Instructions:
Download Official LineageOS-15.1 treble enabled build from here
Download treble enabled twrp from here
Move both the downloaded files to external sd card (recommended)(optional)
boot in twrp
move to wipe option from twrp.
advanced wipe.
select data and then check if its in ext4 if not format it to ext4 ( do this from official twrp by @celoxocis )
then go to install and install the recovery provided above.
reboot to recovery.
wipe system, data, dalvik, cache & internal storage recommended.
install the lineage os zip and reboot.
download GSI of any rom of your choice. if it is in zipped format extract it and make sure you have a *.img
boot into twrp
wipe anything other than boot, micro sd & vendor
go to install option and then select install image button on bottom right corner
select the gsi of your choice which you have downloaded and install it on system partition.
reboot to recovery (important)
flash mind the gapps if you are going to use gapps in your rom. ( important open gapps have a few issues on treble like many of times gapps dont get flashed or shows some error)
reboot
Kudos you have now flashed a Genric System Image on your Lenovo P2.
for how to get rooted with magisk refer to next post.
and List Of GSI is available here
if you have any doubts even after reading this ultimate guide feel free to post it i will try to answer it and help you with that.
after following instruction as mentioned above
* download the magisk from here
* flash it normally.
A list of GSI and download links can be found here.
https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list
Only A arm64 gsi are supported well on our device and based on arch of our device
how to get back to non treble rom?
* Download the non treble rom your choice
* boot into twrp do wipes as suggested on rom's thread and then flash the rom package no need to mess with vendor partition.

I'm on codeexilir's twrp, can't I use that twrp to flash official los 15.1 to get vendor image and then flash any GSI. Or it is mandatory to use los twrp?

Changing system and data to ext4 will do the trick probably

After flashing gsi got decryption unsuccessful error. How to solve that?
something is very wrong......
First if I flash lineage then any other gsi like pixel experience, it gives me decryption unsuccessful error.... I'm not even able to format the storage to remove encryption. I did format the encryption using an older version of twrp as the twrp provided for treble gives an error like ''
Unable to format data. Unble to remove encryption
-Now When I formatted data using earlier twrp and hen flashed the treble one and then flashed lineage. Booted and it still encrypted my phone. So the loop goes on again.
I dont know whats wrong. Treble flashing should be easy... been awake since last night trying to make it ork by using different combinations but no luck.
can anyone help?
Is there any way to enable volte in GSI?
I'm trying to install twrp on the way to installing Magisk Manager but I don't see the Pixel 4a on the device list here:
Google
This is the Team Win website and the official home of TWRP! Here you will find the list of officially supported devices and instructions for installing TWRP on those devices.
twrp.me
Now it looks like there is a custom version of twrp for most of the phone models out there but I'm not really sure that's the case. Perhaps there is only one "lastest version" of twrp for all phones or individual operating systems. Anyway is there a version of twrp for my Pixel 4a running Android 11?
If not is there another custom recovery that anyone would recommend?
Thank you!
I'm also looking for one

You don't need TWRP in order to install Magisk Manager / Magisk framework:
[Guide][Root] Magisk without TWRP on Android P
Via Magisk Manager: This method does not need root, and also does not require a custom recovery. However, you MUST have a stock boot image dump beforehand, and you also have to be able to flash the patched boot image, either through fastboot mode...

As I understand it they're two separate things magisk is a framework and magisk manager is an application that uses that framework. I rooted with magisk no problem but I can't unlock my financial apps without magisk master and a module I believe.
I have the OTA file downloaded and I know how to use adb, but I can’t find exact directions on how to do this. Thanks for any help.

This works for me
Fastboot boot into TWRP,, ( TWRP nebrassy edition)
install trwp via advance settings
reboot into recovery
send a copy of your ota oos over to your phone ,
flash oss ,
reboot into oss recovery
Format data in oss stock recovery

just find a way to relock your bootloader, it will revert you to stock completely.
Hi there,
I updated to ColorOS12 and accidentely rebooted, before flashing Magisk and TWRP.
My question is now: Can flash TWRP the ususal way WITHOUT losing my data?
Bootloader is unlocked of course.
TWRP doesn't work on Android 12 and flashing Magisk with recovery isn't supported anymore anyway.
Are you actually on ColorOS or are you calling OxygenOS ColorOS? If you're on OOS, you can get patched images here (there is a guide linked in the post too).
[DISCONTINUED][OOS & PA] OnePlus 9 stock/patched boot images
Now as we have TWRP for any A11-13 ROMs, there's no need for boot image patching, just flash magisk in TWRP. Hi! There's a great root guide here on xda by @zymphad and i thought i'd share the boot images for different OOS and Paranoid Android...
forum.xda-developers.com
If you're on ColorOS, you won't be able to use these images and will have to do the patching yourself.

I thought it's ColorOS, but now as you're asking.....
LE2113_11.C.48 is Oxygen OS, right?

Yes it is.
Ok, but flashing the boot.img only doesn't erase my data, right?
And after there is no c.48 available in the linked thread, I have to patch it on my own I guess?!

Just boot the C.47 image and direct install once it's up. As long as you don't flash it, it should work to get the device up and running with root to install.
And no, flashing the boot image doesn't wipe data.
Can i unlock the bootloader and then boot to twrp recovery (from pc) to install magisk.zip or does this not work for android 12 ?
TWRP not compatible with android 12, yet.
i presume you know that when you unlock the bootloader, your device will be reset to factory?
Yes I know that unlocking the bootloader will factory reset the device. Is there some recovery I can use with Android 12 ?
I can't find a guide on how to root from scratch android 12.

Didn't look very hard. I made this thread months ago. It's here in op9 section how to guide.
