I have tried these exact steps, but I'm still stuck in booting to recovery every time. I'm not sure how I can solve this. Am I missing a step or doing something wrong?
The 7 steps, as I have performed them, in more detail:
1. Flash latest Q fastboot rom with miflash
Downloaded latest official MIUI 11 fastboot ROM for Mi 9 SE from what appeared to be the most reliable source.
https://c.mi.com/oc/miuidownload/detail?guide=2. (Source:
https://c.mi.com/global/miuidownload/index)
After unpacking the 3Gb file named "grus_global_images_V11.0.2.0.QFBMIXM_20200310.0000.00_10.0_global_0fc5ca5acd.tgz", MiFlash would accept is and I flashed it to my phone (remember to choose "clean" and to bottom in MiFlash and not "clean_and_lock" so you don't have to unlock the bootloader again)
This resulted in my Mi 9 SE booting into a fresh stock MIUI 11. Always nice to know I can fall back to this again if all else fails...
2. Flash recovery twrp and vbmeta and boot into recovery
I flashed twrp-3.4.0 for Mi9SE from
https://github.com/redispade/device_xiaomi_grus-twrp/releases
and (without reboot) flashed vbmeta.img from link in second post on
https://forum.xda-developers.com/mi-9-se/how-to/guide-how-to-flash-twrp-gsi-roms-mi-9-se-t3939254 (again, the best matching source I could find)
Then rebooted by issuing (could not find a better way to "boot recovery" from a phone in fastboot-mode)
The phone rebooted into recovery.
3. Wipe system, cache, dalvick
In TWRP: Main menu- > Wipe -> Advanced wipe. Checked Dalvik, Cache and System. Swiped to Wipe.
4. Format data
In TWRP: Main menu- > Wipe. Clicked the "Format Data" button (next to "Advanced Wipe") and confirmed.
5. Reboot recovery
In TWRP: Main menu- > Reboot -> Recovery
6. On recovery mode, copy your rom into your device(from otg or PC)
Once in TWRP again, copied MIUI 12 ROM from
https://xiaomi.eu/community/threads/20-6-11.56171/ to phone by issuing
In TWRP: Main menu-> Install. Selected the ROM I had just uploaded in /data. Left the "Check zip signature" checked and "Reboot after install" unchecked. Swiped to install. (I've tried both with and without installing the TWRP app after the installation)
7. Reboot
Rebooted the phone from TWRP Main menu -> Reboot -> System
After this, it still just keeps rebooting to recovery (TWRP).
What am I missing here?
