My experience flashing ferrari Mi4i with cm 12.1 from stock MIUI 7, and face bootloop. some thread suggesting flash MIUI stock 6 or lower. Downloading fastboot rom of about 900 MB painful for slow internet. after investigating, the bootloop is caused by CM 12.1 (including Mokee rom) built with compatibility on stock rom 6 or lower. So I repack the tools from fastboot stock rom Mi4iGlobal_V6.5.4.0.LXIMICD and delete userdata.img, system.img, ADDED TWRP-3.0.0-ferrari (to replace stock recovery): modify the script to achieve Mi4i stage to ready to flash with custom rom (cm 12 probably cm 13) and no bootloopTested with cm 12.1
