LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Please, what version of GApps do you have installed ?

With pico & nano I have no issues, but with any other version I have some issues... That's why I recomanded nano. Do you have thé same issue also without GApps installed ? Thanks !

random reboots

Is anyone experiencing random reboots when using this rom?

Also would anyone have stock boot.img and recovery.img for BAH-W09?

Please, for what you need only boot & recovery ?

After flashing this custom ROM I am having problems with going back to official stock ROM ,

Ok, but this ROM (LOS 16.0) also replaced stock system.img & also vendor.img !

Would you be able to guide me through how to go back to stock firmware ? This ROM looks great but I am experiencing random reboots and it freezes from time to time.

 

[surdu_petru]

Would you be able to guide me through how to go back to stock firmware ?

There is two ways to go to stock ...

1° write partitions via "dd" command in TWRP

2° "dload" method !


First solution it's a bit more complicated, you should downloads your stock firmware from here, extract boot, recovery, system & vendor images from UPDATE.APP ( there is a tool for unpack UPDATE.APP on XDA ) .... copy all needed images to a microSD card, go to TWRP & connect USB cable than you should type from your desktop/laptop :

dd if=/external_sd/boot.img of=/dev/block/bootdevice/by-name/boot
dd if=/external_sd/recovery.img of=/dev/block/bootdevice/by-name/recovery
dd if=/external_sd/system.img of=/dev/block/bootdevice/by-name/system
dd if=/external_sd/vendor.img of=/dev/block/bootdevice/by-name/vendor

Warning !

After you have extracted system & vendor from unpacked UPDATE.APP, you'll have something like this : SYSTEM.img & VENDOR.img !
You must sparse the both images to raw images in this way, before to copy them to microSD card :

simg2img SYSTEM.img system.raw
simg2img VENDOR.img vendor.raw

Just rename system.raw to system.img & vendor.raw to vendor.img and copy them to your microSD card !


Second solution it's the common Huawei/Honor installation for UPDATE.APP !

You must create a folder/directory named "dload" into your microSD card & copy here UPDATE.APP !
Power off your device, than keep pressing at the same time all three hardware buttons ( power, volume down & volume up ) untill you'll able to see erecovery dload start installation or something like this !


INFO :
UPDATE.APP it's under update.zip ( so you should unpack this archive to be able to extract UPDATE.APP)
Also, you need a FullOTA-MF version of your BAH firmware !

Good luck !

Thanks ...

BTW I'm working on it to fix more issues .... I hope to be able to make it stable enough one day

Thank you, I'll try method one as method 2 wasn't working for me giving an error message update failed,

This is because I guess you didn't downloaded the right firmware !

For example this update.app downloaded from BAH-W09C233B265, it should match your initial stock Huawei firmware installed on your device, previously installed LOS !

EDIT :

Befor to install LOS, I taked a stock getprop ( adb shell getprop > getprop.txt) and I have this info from my stock Huawei firmware on my device :
[ro.build.description]: [BAH-L09-user 7.0 HUAWEIBAH-L09 C100B018 release-keys]

This mean that I need this firmware : BAH-L09C100B018 FullOTA-MF in order to be able to flash it via "dload" method .

See my problem is that i have jumped into trying this without creating the backup, :/

Yeh, me too ... I didn't performed a backup before started to install some custom ROMs

For me, the first method doesn't seems to work, and this only because I'm not able to start my device into stock recovery ... it's just don't want to boot on stock recovery, and because of this issue, I'm not able to perform a full wipe to encrypt device back ... without this step the device will never boot into stock firmware !

BTW, I didn't yet tested the "dload" method ...
