Vendor Name: Xiaomi
Device name: Mi A2
Device CodeName: jasmine_sprout
Version of /e/OS which existed previously: V1.19.1
The device is Not rooted
The OTA update from V1.19.1 went completely smoothly. A new installation with stock Android 10 Global Firmware V11.0.28.0.QDIMIXM was much more complex because I was unable to get e-Recovery V1.20 to work. Only with the help of an older PitchBlack Recover based on TWRP 3.4.0 was I then able to successfully install /e/OS V1.19.1 - and then update it via OTA update.
I have also successfully installed and tested (disadvantage of my test versions: Gapps are already included):
PixelExperience | Official | Android 13 (T)
PixelExperience_jasmine_sprout-13.0-20231128
DerpFest | Tango | Official | Android 13 (T)
DerpFest-13-Official-Tango-jasmine_sprout-20240211
DerpFest in particular shows that AOSP 11 (R) - see [ Sunsetting LineageOS 18.1 ] doesn’t have to be the end and that there are options. In addition, the DerpFest recovery is not a minimal recovery, but has functions that a Lineage recovery does not know.
