If you have any problem with installation (or something in phone don't work normally), first install standard european ROM S110/113, then install MIUI ROM. Right order is: ROM S110 > CWM > TWRP > MIUI ROM.

If after recording a new version the battery is charging only 96-98%, go into TWRP recovery, enter "Wipe cache" + "Wipe Dalvik" and restart phone. Battery will shows 100%. This is a problem of new MIUI kernel, not the port.
This ROM use in buld.prop file settings "dalvik.vm.execution-mode=int:jit" In this setting, the phone has a higher application performance, but not good GPS accuracy for applications such as sporttracker (sports running) that use GPS location. For car navigation GPS accuracy with this setting is good. If you want use GPS navigation for running (e.g. sporttracker.apk) use setting "dalvik.vm.execution-mode=int:fast". You have to edit bulid.prop file.
