Flash stock firmware through mi Flash tool

Tried that. Flash failed at the end. Then bootloop again.
Any idea ?

sigh, I can help you if you have unlocked bootloader, now only can reflash various versions of stock using various versions of flash tool

go to miui and download the latest rom and just install it with TWRP.
There are currently no Android Nougat versions without bugs expect the official miui rom
Agree
Downloaded latest miui developer rom.. Flashed via twrp.. Now stuck in boot loop... What to do..
You probably didn't download latest TWRP that is necessary for Nougat.

Where did you find twrp?
When I first flashed the twrp that was on eu miui first nougat for Mi Note Pro it didn't work. I then installed twrp that was linked from one of the reply which lead me to Miui Hellas it then worked.
I have flashed every version from that point very easily.
I did a find the link to twrp from one of the forums.. After flashing it.. I can atleast get into twrp.. But nothing else is happening.. I mean I tried flashing the latest developer rom but got bootloop.. Tried restoring the previous rom.. Got bootloop... So.. Got fed up and have downloaded the fastboot rom now and will use the mi flash tool in the evening after I get back frm work.. Hope it will work...and I forgot to mention that when i tried "fastboot oem device-info" i got bootloader locked.. After that i did unlock the bootloader frm mi unlock tool... Plz help..
Before going to nougat you have to put latest lollipop which is I think 6.12.22 then twrp for nougat then unlock bootloader then flash first nougat then I think you can flash latest nougat.

Redmi K20 pro, Locked No Compatible OS

After wiping the system partition when trying to make something work, I got stuck in fastboot mode with no os. I followed the advice given here but I think I flashed an incompatible os, and now my phone is locked, and when I try to boot it it tries to boot into miui then goes into recovery and says "This MIUI version can't be installed on this device." Nither miflash nor miunlock can do anything. Any ideas on how I can fix it?

The Phone got locked when I flsahed the wrong rom with the miflash tool, and forgot to change it to clean all. Now I cannot flash a rom as the bootloader is locked.

It doesn't matter whether the bootloader is locked or not with miflash. Give it a go with the correct rom.
As long as it's an official rom.

I tried, it says: error:FAILED (remote: Erase is not allowed in locked state) for clean all and clean all and lock.
For save user data it says: error:"Erase boot error"
Was there a way to flash without erasing, I cannot remember. But it sounds like you need to flash a rom version comparable to the current one (without wiping), boot, unlock bootloader.
