Guys, MI 9 with STABLE (10.2.16.0) here.
Why I can't update by OTA?
In my case, OTA didn't find any update. I updated from my previuos xiaomi.eu miui 10 stable, with TWRP as usual.
Here my steps.
- updated twrp from fastboot with latest 3.3.1-42 Mauronofrio
- rebooted to miui, then copied miui 11 mi9 stable to memory phone, from my pc by usb as usual
- booted to twrp. Decoded/unencrypted data partition using my pin
- from twrp, wiped Dalvik/Art Cache and Cache
- from twrp installed miui 11
- rebooted... waited about 10 minutes. Yes has took a lot of time to reboot, probably it had to rebuild cache.
- Miui 11 now on the go
- Miui 11 is now working. All my apps and data are availables, ringers and contacs works as usual... I hope they will continue to works even for the future.
