I upgraded to last ver5 miui rom but I had lags so I decided to change it back to ver 4.0 The only way to do this is to install cwm and WiUi. Partition 1: WiUi v4 3.2.22 and Partition 2: WiUi v4 3.2.22 (the same). Everything is perfect but I want to change one of the two partitions to Miui v4 3.2.22 (miui_MI2_3.2.22_5a478a08ae_4.1.zip from http://en.miui.com/thread-1885-1-1.html) I've try many ways (from recovery console cwm v188.8.131.52) and from the updater. The installation is completed successfully BUT when I boot, the mi logo stacks at the start (white mi logo). I would like to note that I install the miui version only in partition 2 (I didn't try in partition 1). Please, help me! thank you for your time!
