My experience - PIXEL EXPERIENCE PLUS (A11) - GSI-Unofficial

[LouisN39]

I found something weird: on stock rom, google play store says that the device is not certified and on any other gsi, the device is certified

 

[LouisN39]

And another question : do LOS19 have the same problems than PE/PE+ (A12L) (Bluetooth problems)?
EDIT: tested los19 and it seems that the bluetooth problems come from Android 12 itself
EDIT2: tested dotOS 5.2 works good but seems to overheat when fast charging (with ambiant temperature of 25-30°C/77-86°F)

The same with ArrowOS 12 S.

Hey Guys, how do you fix the Bluetooth issue?

Install like any other GSI Rom including the Nfc patch.

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:

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 :

(Note: If you don't plan to use TWRP, simply install patched Recovery_ramdisk in fastboot mode. Run command
fastboot flash recovery_ramdisk magisk_patched-23.img ).

Hi,
thank you for the amazing instructions. However, my device accidentally booted (successfully) after step 5. When I then returned to eRecovery to perform Factory Reset, my device automatically booted into TWRP.
Also, I was not able to successfully perform step 3 as described in this post: https://forum.xda-developers.com/t/rom-official-anne-9-lineageos-16-0.4151163/post-87217581

From another topic:

You can solve the problem with this app

What you will need:
1. Unlocked bootloader
2. Android phone rooted with magisk (the phone should have OTG support! )
3. OTG data cable
4. "ADB & fastboot for android NDK" magisk module
5. "TERMUX" app

(I hope I didn't forget anything...).
I tested this method on normal fastboot operations (bootloader unlocking, TWRP...), theoretically it is also possible to install a custom ROM.

Could you please also describe how one can update from one PE12 build to a more recent PE12 build? Is it as easy as wiping Cache & Dalvik, flashing the system.img from the new build (via fastboot or via TWRP), maybe wiping Cache & Dalvik again and then rebooting?

Also, have you tried PE13 yet? I used your instructions from the OP (except I’ve been on PE12 and not on stock EMUI 9.1) but my phone does not boot the flashed system.img, but instead always automatically reboots into recovery or bootloader instead.

 

[AltairFR]

Use a permissive phenix kernel or wait for the next release. I fixed the problem for p20 lite

And your fix for P20 Lite will be included in the next PE13 release on this GitHub Site?

I don't have P20 lite anymore so no more experiments .
As I said before, A12 GSI is only cosmetic, everything important is already included in A11 GSI (I mean Kirin-devices of course).

 

[iH8ra!n]

Yes

UPDATE 2: I tried to update from the latest PE 12.1 build. I only wiped Cache and Dalvik and then flashed the October 4 PE 13 build via fastboot (and wiped cache and dalvik again, eventually). But my Huawei P20 Lite still boots into eRecovery (Huawei Stock Recovery) every time I try to reboot into system. It does not matter whether I try to reboot from bootloader, recovery, eRecovery or from Power Off State. I guess I have to be a little more patient then.

UPDATE: Trying this one now.

I tried the latest release which reads "Fix boot for some devices" in its changelog, but for me it still boots into recovery. Are you aware of this?

Thank you for your effort!

PE 13

you need to start with stock android 10 if memory serves me right...
Try vndklite version (due to r/w system).

Thank you for the suggestion.
Since I cannot find a stock ROM image anywhere, this means wiping System and then restoring via eRecovery and HiSuite and then updating all the way to A10, right?

p20 lite cannot be upgraded to stock A10

 

[iH8ra!n]

p20 lite cannot be upgraded to stock A10

Okay, then it will be rather difficult for me to start PE13 installation with Stock Android 10 being installed.

So, your second suggestion now is valid, i.e., trying the same that I did earlier and described above but with the vndklite variant?!
