On crdroid A11, and actually stick A11 come to think of it, I'd get sick in such a bootloop where I was forced to do a factory reset. Nothing could fix it. I'd like everything that wasn't backed up.
Until TWRP. That would at least allow me to get my files, but all my way app data was gone.
This would happen at least once a month, it was horrible.
So far haven't had it happen on stock A12, or crdroid A12
