[ROM][Huawei][13] LeaOS - Lineage 20.0 for Huawei device (EMUI 9.1 version)

[muhammadbahaa2001]

Must I have kernel 4.9.148+ installed or must I have EMUI 9.1 installed in order to get Android 13 GSI working on Huawei?
Does it releate to kernel version or EMUI version? (I know EMUI 9.1 includes kernel 4.9.148 but I want to know which one is must).

Emui 9 provide kernel 4.9.148, you can use the stock kernel

Well, I flashed the stock kernel version 4.9.148 the phone got stuck at bootloop untill I rolled back to kernel 4.9.111.
Note: installed firmware is EMUI 9.0 not EMUI 9.1.

 

[AltairFR]

Oh yes , you must have emui 9.1

Hi, does this ROM needs the phone to be decrypted? I was trying to encrypt the phone through settings>security, but it doesnt return anything. Is that last thing supossed to be that way? Thanks in advance.

Ok, so I got this rom up and running but by pure luck I think.
LeaOS - Lineage 20.0 seem to run just fine. Not tested all things, but it runs stable,
but it does seem a bit slugish (too used to the my new oneplus 8T)

I downgraded the firmware to be able to get a unlock code for the bootloader using (dc-unlocker not free).
I got the latest firmware I could find installed (P20 Lite Anne-L21 9.1.0.355)
Extracted the recovery_ramdisk image from official firmware (with HuaweiUpdateExtractor_0.9.9.5)
In HuaweiUpdateExtractor, remember to uncheck all verify options in the settings if the program won't open
the update.app file found in the stock firmware. The bootloader and recovery_ramdisk are the same thing?

Got the twrp-3.7.0_9-0-anne, SHRP_recovery_anne_yahia-4-12-2022 (Sky Hawk Recovery), and Magisk-v26.1 ready.
TWRP only show a 9.0 version - is it compatible with version 9.1?
TWRP did not show any option to flash ramdisk image to erecovery!! SHRP does so I dropped TWRP.

As it sits now I have the phone running with unpatched bootloader (stock ramdisk) flashed to e-recovery.
And Sky Hawk Recovery flashed to normal recovery. I can't get into android with root access.

On first boot the stock bootloader flagged an error and wanted me to low-level format the phone,
but after a reboot it loaded the custom rom normally!

I tried to run Magisk and get a patched bootloader installed too, but when I tried to boot the phone
it would be very slow and when it got into android it would stay there for a few seconds and
automatically reboot.
I was actually at some point able to get the phone to start and I had root access, but it would have major
issues with startup. It would just hang and take forever to boot. Not sure how I managed that...

CPU-z info:
buildID: TQ3A.230605.012
kernel: 4.9.148

Various key combination to access the recovery system (P20 lite).
Just adding some findings on how my phone now operates:

No usb attached: (I think it behaves different with usb connected)
boot custom recovery (TWRP, SHRP etc.) -- Phone OFF->hold V+ & Power (not releasing any buttons)
boot stock (e)recovery -- Phone OFF->hold V+ & Power (release power after screen wakes)
normal boot (no root) -- Phone OFF->Power...

fastboot -- Phone OFF->Connect usb to PC->hold V- & Power

The bootloader and recovery_ramdisk are the same thing?

Of course not.

I can't get into android with root access.

Use recommended
TWRP
As for magisk root, look
here

 

[craigsoup]

Of course not.

Use recommended
TWRP

So I found the recovery_ramdisk image, but no trace of a "bootloader" image (that is supposed to be patched).
And "of course not"? Please, I'm an amateur here, don't be rude...

Thank you for the links! Those were really helpful

Here is some feedback and observations I've made when using Android 13 on my Huawei P20 Lite.

LeaOS
The problem with this OS is that it doesn't auto detect your device model, causing it to enable features not available for different variants. For example, my P20 Lite is a ANE-LX2 which doesn't have support for NFC. This can be solved by either spiting different models or some other method that I can't think of. NFC currently constantly crashes in the background.

Another thing I observed is that Bluetooth audio is slightly broken. It crashes every so often which makes it nearly unusable. I forgot to capture logs but I think it isn't hard to figure out.

LineageOS TrebleDroid
This is more stable for my device., but suspend seems to broken. Sometimes Spotify doesn't work properly when dozing and Bluetooth audio cuts in and out every so often. It is also smoother than LeaOS. Pausing music when using Blueooth headsets is completely impossible as it complains about not sending any data.

I think I might do my own builds later, but I currently don't have the time to do so. If the author wants testing and building help, my i9 13th Gen rig with me in summer holiday can provide some help.

Yes..but to try this rom..twrp is not necesserary

 

[well83]

Yes..but to try this rom..twrp is not necesserary

Thanks for your reply. But for installing original huawei camera or magisk i think i need twrp. If you have a link. Could you please share it.

 

[well83]

Yes..but to try this rom..twrp is not necesserary

Hi. I tried your rom for vtr p10 but it gives me sparse flash write failure. Seems too big
Edit
Without gapps it's flashing but it's unusable without this patch for screen not working on sides https://github.com/Coconutat/GSI_Generic_Fix_Magisk_Module_For_Huawei_P10/releases
so it's always twrp issue

 

[baxxx2]

is any version of this stable?
I get anroid app media stopped working crashes all times

Unfortunately, my device is unable to make and receive phone calls using the preinstalled dialer. Occasionally, I can make the callee ring but sometimes telephoning just fails completely and the network indicator on my devices switches to the symbol that indicates that there's no reception while the dialer attempts to connect. If the callee answers the phone, no sound is transmitted and after a few seconds the call is ended.

Thanks for this rom sir, I've flashed it successfully on my Huawei Y9 2018. I have also created a repository with guide on how to resize the system partition. https://github.com/sadiqsalau/android-device-huawei-y9-2018
