Guys, can someone please help clarify a few things before I flash this on my GSM Galaxy Nexus? I'm on stock 4.2.2 and CWM Recovery 6.0.2.3 (latest for maguro). I haven't flashed any ROMs since 4.2 and am behind the curve on what issues to expect upon flashing to MIUI which is based on 4.1 and then restoring back to a nandroid backup of my current stock 4.2.2 later on. I gather that multiuser introduced since 4.2 will mess with the data on my SD card and that flipflopping between 4.1 and 4.2 ROMs isn't a good idea. Any guidance of how to carefully flash MIUI and restore back to stock is much appreciated. Don't want to end up with duplicated SD data inside multiple nested /0/0/0 folders upon restoring to 4.2.2.
