I am compelled to write this tutorial with the urgency to assist those having the fear or simply not knowing "How To". Between my 2 units of Redmi Note 3, I have experiment, probably a dozen times into flashing and other stuffs which is not a pleasant experience, as I do get my heart tumbling, when I come to a point when I am not able to switch on my device or laying there motionless, so to speak. Anyway, it is quite difficult to get a bootloop or to bricked your device with some acquired skills.
This is a "Successful Hands-on" experience which I simply need to share especially with the newbies, and overcoming the fear to do a right thing...

1. Preloader "Tick or Untick" field:
- If you are using a vendor ROM, in most cases they have altered the MIUI Version via a Build.prop editor to their choice, eg. 7.00.99.00 which is based on 7.0.9.0 officially, leave it "as-it-is" "Ticked".
- If you have flashed prior to this, a Custom ROM eg. SphinX v*.** only then you "Untick" or get back to the OP and enquire how to flash to a Stock / Proprietary ROM / Firmware or another Custom ROM to avoid corrupting your kernel thereafter "Bricking" your device. Should you "Bricked" your device, there are procedures to unwind that.
