IMPORTANT! Before booting up the ROM, you will need to perform a factory reset in stock recovery!

Quick and easy way to install GSI & NFC :

1. Extract the ROM .img file from the compressed file.
2. Flash extracted ... .img in fastboot , use command
fastboot flash system (file_name).img
3. In fastboot flash TWRP over eRecovery (!) - guide:
https://forum.xda-developers.com/t/rom-official-anne-9-lineageos-16-0.4151163/post-83603363
4. Run command fastboot reboot , enter TWRP (press and hold Volume Up)
5. In TWRP unmount all except SD Card , Vendor and System (unmount and mount again if needed) and flash NFC patch

6. Go back to the TWRP's main menu, select Reboot > Recovery.
7. Now you can perform factory reset in stock Recovery.
Note: the TWRP will remain instead of eRecovery.

MAGISK ROOT :

Thanks for sharing !
Is there any difference between Lineage and Pixel Experience?

On Pixel Exp. some things work easier and more flexible . And I don't think it's just a placebo

 

[joenuts2124]

Thanks so much I've been looking for an android11 pixel experience for the p20 lite
Can you use magisk with this?

 

[-Alf-]

Can you use magisk with this?

GSI rom is not related to recovery_ramdisk, so it is possible to use the Magisk root on any GSI roms .

 

[Incomtus]

I was recently thinking to switch on that rom because there are no more lineageos updates.
Is there an easy way to backup and restore data from lineage to pixel?

Try this method
https://forum.xda-developers.com/t/migrate-custom-rom-migration-tool.4252863/

There are several options, I do not remember exactly, but I think that the best results I had with Flasher & Helper

 

[Incomtus]

Tried it but magisk is not working....

...not at all, or for Migrate only ? And what about SuperUser?

 

[joenuts2124]

DSU Loader not working, phone don't support?

DSU Loader not working, phone don't support?

DSU loader requires a/b partitions (two different system partitions).

Doesn't emui 9.1 have ab?

It should be clear, hm?

"AB" in GSIs is not the same thing as physically having AB partitions .
"AB" in GSIs means SAR - system-as-root ( on EMUI 9.1).
P20 Lite supports Project Treble AB, yet is an A-only device ( does not support Seamless Updates).

Not at all, it says like if was not installed, I tried super user app and it tells like not rooted. I have almost same Magiqk issue with Andy Yann lineage but Superuser is working on Andy Yann

IMO you are doing something wrong .
If you have followed instructions in OP to the letter, it must work. Today I tested SuperUser, also works .
Try total clean flashing - flash service ROM and try again.

Very strange i made a clean install,
I went back to stock 9.1.0.132 with DLOAD
I unlocked bootloader and flash the rom with fastboot, i flashed TWRP (9.1) for nfc,
I made a wipe with stock recovery, I booted again on TWRP , i flashed magisk mount fix reboot again on TWRP flashed patched recovery on recovery, and exactly same issue,
I used the same twrp for nfc and magisk. Magisk aint working on last andy Yann build either but works on Emiritein Lineage Os build ( but this one is older)

Did you tried with last build?

For Pixel I tried superuser app on fdroid but doesnt work

 

[-Alf-]

Did you tried with last build?

9.1.0.257

For Pixel I tried superuser app on fdroid but doesnt work

And why not the superuser linked in OP? Okay, your choice bro...
I'm afraid I can't help you anymore.

 

[Incomtus]

I did not see there were an Superuser app in op I was confused with Andy yann forum I made a mix with that two posts
But it is strange that magisk doesn't work if it works for you
Do I have to flag magisk AND superuser ZIP file ?

 

[-Alf-]

flashed patched recovery on recovery,

Then you need boot Recovery to get root permissions (due to patched ramdisk)

I did not see there were an Superuser app in op?

"Root with Phh SuperUser :
1. In TWRP flash Zip.file
2. Install Phh Superuser apk .(if needed) https://mega.nz/file/A4sWFYxZ#9KMkvKRgzU7oCvgThPFQOpv_wKAnLZcZVWcJ03HDyNE"

Yes I know that I have to reboot on recovery that's what I did, as I use to do it with other GSI. But I did not understand I have to root with phh also
