I am pretty sure you flashed via twrp without format data first.
reinstall twrp and proceed as normal. format data in twrp wipe section.

As I understood he cannot do that because either twrp or fastboot don't stay but reboot immediately.
Concerning file explorers it is not the root permissions that triggers the problem, BUT IF YOU ADD OR CORRECT SOMETHING IN SYSTEM PARTITION.

You can try 2 methods to enter EDL mode and recover the phone. The first is to use a USB cable and create a bridge by joining the green cable (positive data) with the black (GND or negative), then you try to glaze with the Miflash tool, in theory you should recognize it in that mode. In the second method you must uncover the phone and use the test points above of the battery and create a Bridge with a metalic object in orden to enter un the EDL Mode.

I have successfully changed the hosts file with my own file in system/etc.
This is system partition? right.
Done on 11.05eu and on twrp installed 11.08eu with X-plore file manager. (should be same with other FM)
Disabled root after modification done. still Magisk installed.
It is matter of testing, don't ask me to make more modification..... until issue is fixed or well understood.

Use Miflash tool and a fastboot rom if you can't get back TWRP

Same problem here. Did you have any solution if yes, how did you fix the phone?

I faced the problem too with my redmi note 9 pro global..before it i succeed with unlocking the bootloader, flashing unofficial twrp, rooting the device with magisk..but when i tried to flashing with xiaomi.eu rom the problem came out..tried to power on the device but it just show problem with 1 sec with the redmi log & 1 sec with fastboot logo..
I have tried to reflashing with the original global rom using miflash & also qpst but still failed..
Need a solution ASAP:crying:

You need an authorized mi account to do that but now xiaomi has restricted to give authorization to new mi account..in other word, flashing using miflash is useless now except if you can patching the prog_ufs_firehouse_sm6250.elf to bypass the mi authentication..

If bootloop, just reflash using mi flash with official rom on fastboot mode..
If hardbrick, no solution yet..send the device to mi center to fix it

What is the codename of device you have? Curtana or Joyeuse?
You guys are probably confusing both devices as One and flashing wrong ROM zips that leads to hard bricks.

Yeah..mostly because of it
Afterall, all xiaomi phone are suckk..
Why not have they just sell only one variant to all of country..why'd they use the same global name for 2 different codename of phone..
I don't understand..

Yes there's issues with naming system but that's where codename comes in, right? Why can't people just read probably ?

I have the same problem. Installed xiaomi.eu rom verison 11.04, tried to update to 10.11 and stuck. What can cause that? I did exactly what they asked me to: formatted the /data partition (ONLY), installed via TWRP.
First time trying modified rom, it's a very bad experience and very time consuming. Probably won't ever going to do that again. :|
