I and Xiaomi/Mi are not responsible for bricked devices, corrupt system files or thermo-nuclear war in your world,
YOU are choosing to make these modifications, and if anything went wrong then it will be because YOU choose to do so.
IMPORTANTUpdate: Since Some time around Jan 2017 the edl command used in this tut is been disabled and no longer works. So check for your MIUI version and then if its stable/dev rom prior to that, then try this. On Redmi 3S running later version of MIUI there is high chance that this tut won't work.
