Described many times. Follow the discussion (as it evolves) and read what other members postany idea why the TWRP recovery was released for MI 11 when the earlier ROM's were fastboot and what is the decision point or who decides whether its a fastboot or Recovery rom for MI 11 ? why was it shifted from fastboot to recovery ( the latest one for A12 - MIUI 13 ). Please advise.
\Thanks
Xiaomi.eu development team makes the decision
Decision point is the availability of custom recovery (usually TWRP) for the given model that supports MIUI 13/Android 12.
And important remark - that does not mean (in case of A12) the 'official' TWRP.me - therefore it is important to follow discussion because it has been many times answered where to look for the appropriate custom recoveries and where to find installation instructions (posts with those answers/links do not need to be given for the same device because download repository and instructions are for the various models)
