That depends on how old was the firmware you had installed with your last MIUI update. Better update firmware at this point than struggle later.
unfortunately this is not descriptive enough for me / it doesn't ring a bell:
- are you sure that you have your data partition unmounted in step 1 of my instruction?
- what does it mean "I can't CHANGE FILESYSTEM -> EXT4."? you can't click it or what?
- on the bottom right corner of TWRP there is an icon you can click to show TWRP console / log. Make a screenshot of it after your failed attempt.
How do I check this: "are you sure that you have your data partition unmounted in step 1 of my instruction?" ?
When I go to "MOUNT", data is unclicked.
I tried this "2. Format DATA using advanced wipe, i.e: WIPE -> ADVANCED WIPE -> select 'DATA' -> REPAIR OR CHANGE FILESYSTEM -> CHANGE FILESYSTEM -> EXT4", but in the command window an error message appeared related to "failed to mount data" or something like that. And I was not able to do it.
Next time, I will include a log. I don't know how to solve this problem.
PD: Does rebooting to recovery from twrp help? It's something I've read in another post.
