I installed the October 2020 update for my Xiaomi A2, and then it entered a reboot loop, giving me a "Cannot load Android system" message.
Actually, when I boot up the phone, I automatically get to the recovery menu, which only gives me two options: wipe the data partition, or reboot. And rebooting sends me back to the recovery menu.
Here's what I did:
- First, using fastboot, I reinstalled the entire OS except the data partition. That ended up in the same reboot loop.
- Then, using TWRP and executing it with
fastboot boot twrp-3.4.0-1-jasmine_sprout.imgI could
adb shellinto my device. From there I ran an
fsck -fwhich did find a couple inode problem. But fixing those problems still did yield the same reboot loop.
- Using TWRP again, I locally cloned my data partition using
adb pull /dev/block/mmcblk0p69 data.img, then I tried the "wipe the data partition" option. My phone did reboot properly, but of course it was reset to factory settings.
Question: is there a way I can restore my phone to a working state with my previous data? I really don't want to reconfigure all of it…
Also I don't really understand what's the problem with my original data partition. Is there a way to know why Android doesn't want to boot with it and why it sends me to the recovery partition?
fsckon the local
data.imgsays it has no error whatsoever
- I can mount the
data.imgand browse it. It's full of, well, files!
