1) Extract file from the recovery.zip and flash it with sp_flashtool
2) Install via Recovery
Copy the MIUI ROM to your SDCARD reboot recovery (Turn on the phone while holding the volume up)
Do a backup first and than:
Wipe Data Factory Reset & clear cache,Wipe Dalvik Cache (very important step).
install and reboot, the recovery, install the gapps in order to have google app.
N.B. If after installation phone wouldn't turn on than flash your boot.img or your lk if it still doesn't turn on than flash again your stock but swap the recovery file in order to have it already, so turn on your phone and restore your back up.
Which author of this Rom decline any liability for whatever may happen to Vs device as a result of the flash itself.
If you are afraid, then don't install anything and you will sleep peacefully the night, otherwise you do it at your own risk!
In any case, just do a Nandroid backup before installing anything and every problem should be averted.
Enjoy this is my first ROM so I hope you will find everything works
