Thank you for your quick reply.Yes this recovery is safe to use. Also you linked miui for Mi 10T not for Mi 10T Lite. For Gauguin you can get Miui from here: https://xiaomifirmwareupdater.com/archive/miui/gauguin/
I personally used 126.96.36.199 and it worked without any problems
A notification says if I click, the version V188.8.131.52.QJSEUXM will be installed (514 MB) .
Does this mean I do not have to do any further actions?
1) Approve Update
2) Install OrangeFox
3) Format Data
4) Install this ROM
5) Wipe listed partitions
Is this correct?
This is the screenshot of the notification (unfortunately in German).
