realme X RMX1901 (CN Chinese version) Halium 9

almas · 14 Oct 2022, 15:32

I followed Porting guide and created a halium-boot.img file and flashed with fastboot successfully.
But my phone couldn't boot up with the error message "the current image (boot/recovery) have been destroyed and can not boot"

I did following:

mkdir halium && cd halium
repo init -u https://github.com/Halium/android -b halium-9.0 --depth=1
repo sync -c -j 16
code ./halium/devices/manifests/realme_RMX1901.xml
Added following:

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
	<remote name="sagar" fetch="https://github.com/SagarMakhar" />
	<project path="device/realme/RMX1901" name="android_device_realme_RMX1901" remote="sagar" revision="lineage-16.0" />
	<project path="device/realme/sdm710-common" name="android_device_realme_sdm710-common" remote="sagar" revision="lineage-16.0" />

	<project path="vendor/realme/RMX1901" name="android_vendor_tree_realme_RMX1901" remote="almas" revision="master" />
</manifest>

I didn't find official Lineage OS sources. But I found unofficial ones and used them.

I extracted vendor blobs from stock firmware with the Android 9 version following the guide https://baalajimaestro.me/posts/extract-vendor/
Then I created a repo and added extracted vendor blobs to the https://github.com/almas/android_vendor_tree_realme_RMX1901
./halium/devices/setup RMX1901
hybris-patches/apply-patches.sh --mb
source build/envsetup.sh
result was:

Trying dependencies-only mode on a non-existing device tree?

It created halium-boot.img file with size 19M. But boot.img file in stock firmware size was 64MB.

What did I do wrong? Please help me.

I flashed vbmeta and dtbo before flash boot. Now it seems succeeded to boot. But it's in boot loop.

fastboot flash vbmeta vbmeta.img --disable-verity --disable-verification
fastboot flash dtbo dtbo.img
fastboot flash boot halium-boot.img

Downloaded the Halium 9.0, arm64 (64 bit): ubuntu-touch-android9-arm64.tar.gz (https://ci.ubports.com/job/xenial-hybris-android9-rootfs-arm64/)
Downloaded and extracted the Halium 9 LXC container image (GSI). (Link on the manual https://docs.ubports.com/en/latest/porting/build_and_boot/Halium_install.html was broken. I downloaded halium_halium_arm64.tar.xz from https://ci.ubports.com/job/UBportsCommunityPortsJenkinsCI/job/ubports%252Fporting%252Fcommunity-ports%252Fjenkins-ci%252Fgeneric_arm64/job/main/)
Downloaded and extracted https://gitlab.com/JBBgameich/halium-install
I executed the following commands when I entered custom recovery and plugged the phone into the computer.

adb devices

./halium-install-master/halium-install  -p ut -s ./ubuntu-touch-android9-arm64.tar.gz ./system/var/lib/lxc/android/android-rootfs.img

But currently, it's in a boot loop...
