Bootloop in Fastboot screen after flash Android 9 ROM - Xiaomi Mi 8 Questions & Answers

Hey guys, I've got some problems with my Mi8.
After flashing a zip I wasn't supposed to , I got stucked in Fastboot bootloop.
I tried to flash the stock ROM and it turned out to work, BUT just the android 8.1 version. When I try to update it to android 9 or try to flash it, I get stucked in fastboot bootloop again.
Do you guys have any idea of what could I do?
Thanks! :good:

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.

Hi, i think my honor 5 c is hard bricked. i cant acces stock recovery nor twrp recovery. First i wiped system to install emui 5.0 but it didn't worked. then i tried another recovery but i didn't start. So i replaced stock recovery with twrp that also didn't worked. I tried to flash system through fastboot but it didn't worked neither. Then i don't know why i relocked my bootloader because i thought it will restore stock recovery but it didn't.

Charge the batrery, unlock the bootloader, install twrp from p9 lite section, boot to twrp, and flash the custom roms or download the rom given in rom section of p9 lite, may be arsenik and restore it in twrp.
