Need help porting to Xiaomi Mi A1 (tissot)

turanmahmudov

Hello everyone. First time trying port.

I followed this documentation:
https://docs.ubports.com/en/latest/porting/build_and_boot/H9_build.html

My manifest file for the device is like this:

<?xml version="1.0" encoding="UTF-8"?>
<manifest> 
    <remote name="hassan556"
            fetch="https://github.com/hassan556/"
            revision="refs/heads/halium-9.0" />
    
    <project path="device/xiaomi/tissot" name="android_device_xiaomi_tissot" remote="hassan556" />
    <project path="device/xiaomi/msm8953-common" name="android_device_xiaomi_msm8953-common" remote="hassan556" />

    <project path="kernel/xiaomi/msm8953" name="android_kernel_xiaomi_msm8953" remote="hassan556" />

    <project path="vendor/xiaomi" name="proprietary_vendor_xiaomi" remote="hassan556" />
</manifest>

My device was Android 9 before starting to port. I tried 2 methods:

I flashed TWRP, installed ubports_GSI, then flashed halium-boot.img.
Downloaded rootfs and GSI as it mentioned in the docs, installed with halium-install script, then flashed halium-boot.img

Both methods work and I have access to device ssh.

The problem is device stuck in bootloader. As I understood lxc doesn't start properly.

I can get the logs you need to debug.

Thanks.

Be patient. We all have real lives to lead before looking here.

@turanmahmudov try to start container in foreground and see for errors. The lxc-start command has a flag for that

turanmahmudov

@flohack this?
# lxc-start -n android -F

GUI loads. The device is very very slow.
No WiFi, No Bluetooth, No SIM, No GPS, No Sound

I thought the GSI was no longer supported or us this something else?

turanmahmudov

@lakotaubp yes, GSI didn't work for me. I built halium-boot.img and system.img
The device boots into Lomiri UI, apps work.
All the other stuff doesn't work. I will start from scratch.

I have Xiaomi Mi A2 and a car Citroen C4. I have paired the phone but only hear the calls in it, not in the car. I can't listen the phone's music in the car. If you can do it in A1, it would be the solution for A2.

rapto

I tried to follow the instructions. Now it says "the system has been destroyed". ¿Any chance of recovery?

rapto

@rapto Never mind. Started from 'flash stock rom' and retrying...

rapto

@rapto Nope. System destroyed again. There must be something I am not doing right.

@turanmahmudov Thank you for sharing . Is it your last build?

almas

@turanmahmudov I just finished flash and can not boot. It's with a white screen with three color bar and mi logo. How can I boot or ssh to my phone? Please help me.
