I've been running MIUI for a little while, mainly on 1.12.2 I think. I updated last night to 1.12.9 and it's really too unstable for me. I've been trying to work out how to roll the update back. When I applied the update I backed up (using the MIUI tool?) but now can't find a way to restore that backup. I really don't want to have to wipe the phone again, besides the fact that the 1.12.2 download is not accessible from anywhere obvious. Any help appreciated.
