Selinux-fix-Yahia-V5.0.zip: Selinux fix for Pixel Experience A13 including missing selinux policies for offline charging (it may work with other GSIs, if not you can back to sock vendor policies by flash selinux-Stock-Yahia-V1.0.zip or from your vendor backup)

- Backup Vendor partition
- It also disable encryption
- Flash "Selinux-fix-Yahia-V5.0.zip" using TWRP


Selinux-fix-Yahia-V2.0.zip works with Pixel Experience A13

Hi!

What you have done to fix it? Is the error just for android 13 right? I might do a branch just for android 13

Cheers

I don't want to create a seperate thread for this so here goes.

I tried to merge all patches related to Android 13 in a single package. This includes @AltairFR 's NFC, DRM and offline charging fixes, @Abdelhay.ali 's selinux rules and to top it off some tweaks from here and there from me. I made sure it can be flashed from official twrp, can't promise same for modified twrps.

I also made an opt version which doesn't include selinux rules since required ones are already merged to trebledroid. I recommend flashing that one, if you can't boot afterwards flash @Abdelhay.ali 's selinux patch above.

What it does:
- Edits vendor build.prop for safetynet
- Edits system build.prop for performance and spoofing phone model
- Edits vendor fstab to remove encryption
- Edits vendor selinux rules to boot enforcing
- Adds DRM service and required fixes to both system and vendor
- Adds NFC config files to system and system/product
- Adds iceow's offline charging binary & images and edits init.rc accordingly
- Removes unneeded com.android.vndk.vxx folders from system_ext/apex to save some space
- Added ability to resize system before extracting stuff

(twrp might say zip is flashed even tho it didn't because of resize functionality, that happened to me only when I dirty flashed it so I recommend flashing this before booting your system)

I'm a dumb dumb who can't figure out how to sign a zip so here's CRC64 to check for integrity manually :
1.3.1 : AC55639A998DA2B4
1.3.1-opt : 436BCBE5DECF34E0

Also I don't want to create another zip just to go back to stock, all you need to do is get stock vendor image from here and flash it over vendor via twrp. adb push VENDOR.img /sdcard will send it to internal storage, from there you can install image.

Good job frax3r !!!

Update
There are two versions of stock kernel 4.9.148 :

1- Sock kernel 4.9.148 for emui 9.1.0.401 from here extract by Frax3r

2- Sock kernel 4.9.148 for Emui < 9.1.0.401 attached


Thanks @AltairFR for this information


--------------
Stock Kernel 4.9.148 for Emui < 9.1.0.401 backup from TWRP

Because I didn't find any worked .img for 4.9.148 stock kernel. I have attached my Stock Kernel 4.9.148 backup from TWRP. You can use it via Restore option in TWRP after decompress it.

Use Huawei Update Extractor.

 

[Abdelhay.ali]

Use Huawei Update Extractor.

Thank you for your reply. I have already used it, but the output kernel.img not working on my device. Also, I have tried this from @Frax3r, not working too. (It is boot to fastboot with error message)

You can see the size of the extracted kernel is 24Mb and the normal kernel size around 12Mb

extracted kernel is 24Mb and the normal kernel size around 12Mb

Are you sure?

 

[Frax3r]

Are you sure?

Yes. Ask huawei enginners why they put 12 mb of empty space.

Maybe I don't understand it (I'm just a hobbyist), but when the extracted kernel.img is 24Mb and the your TWRP backup kernel.img is also 24Mb, where is the difference?

TWRP take a backup of the whole kernel partition including space.( Like backup system and backup system image).

This is not our problem . There is an error in extracting kernel from UPDATE.APP using Huawei Update Extractor at least with me. I have mentioned size of the extracted kernel to indicated that.

Just ignore checksum in option of huawei extractor or use linux extract script

I have used both methods. but after flash the kernel, it does not boot normally . I attached the error

anyway, I can return to stock kernel using my backup

Check your usb cable, I had the same issue. Turns out cable was faulty. Even my proper cable corrupted few images while flashing, switched usb ports and it flashed uncorrupted. Try different usb ports, if it's same switch cable.

You can also prefer usb-a port

Hi,
I'm trying to install pixel experience on my phone with this guide and I'm using the first recommended twrp. When I want to flash the AIO fix zip file, both adb sideload and install from twrp show the error

'Failed to mount /system_root (invalid arguement)'​

I tried many methods from the google search and nothing works. I tried mount /system rw manually, both twrp mount and terminal not working and resize file system from twrp wipe also failed.
How can I solve this? Thanks for your help.
