today also for me, stuck in bootloop! Seems to system partitions was broken because after restock stock blobs and stock repartition, and flash any miui rom, there was only 1.1gb available. So i've restored a miui rom from fastboot and then storage was fixed. Now i'm tring to flash another time this rom that's very smoth and fast. I hope that this problem will be fixed in few times.
Edit: impossible to flash this rom, maybe my storage was really corrupted, after flash all like in first post my mi pad stuck in mi logo. So SAD!!!!
