[Android] Upgrading LineageOS 18.1 to 19.1 on my Xiaomi Mi 8 (dipper)

 , , , , , , , , , ,

Install the Android Debug Bridge (ADB)

https://wiki.lineageos.org/adb_fastboot_guide.html
https://github.com/M0Rf30/android-udev-rules#installation

# check if device is found
adb devices
# reboot into sideload modus
adb reboot sideload

Or manually boot into TWRP recovery, holding Volume Up + Power when the phone is off. Navigate to Advanced -> ADB Sideload.

Update MIUI Firmware

Following the docs, I first had to check the Firmware version. V12.0.3.0.QEAMIXM was required, and I already had it installed.
If you’re on an older version, download the right MIUI Firmware for your device from https://xiaomifirmwareupdater.com/firmware/dipper/.
Flash the new Firmware via TWRP or via ADB sideload.

adb sideload fw_dipper_miui_MI8Global_V12.0.3.0.QEAMIXM_7619340f8c_10.0.zip

Download and flash new LineageOS image

I’m using the LineageOS fork LineageOS for microG. Download it from here: https://download.lineage.microg.org/dipper/ (MI 8 = dipper)
The upgrade steps are the same as for the official rom: https://wiki.lineageos.org/devices/dipper/upgrade. In my case only flashing the new image.
