Inside TWRP:

Advanced Wipe

Wipe everything except (System, Micro SD Card and USB OTG) Very important!
Now go back and Format Data and Swipe to Factory reset too.
Now you can put Xiaomi EU rom on internal storage and install and reboot.
Its gonna be work.

I'm on 8.12.6 but only after i use this method:

1) Reboot to fastboot mode (press vol(+) and power) wait for vibration. (the screen is also black, don't worry about this).
2) On computer install previous firmware via fastboot: ( https://androidfilehost.com/?fid=11410963190603853188 )
3) Your phone will reboot and fixed.

Solution by @mbppereira.

after that I manage to open TWRP and try to ReFLASH again with Xiaomi.eu 8.12.6 to be sure there is no more black screen and.... it always IS

So If next update will came in i will have to wipe everything again I suppose....

Still I can't install China Via MIFLASH from links you gave here.... And Follow your solution

I have Unpacked ROM set directory and it gives me Error "can not find file flash_all.bat"

I'm from Poland BTW:) maybe this will simplify something...:)

Hi! Help please! I have mi5x. installed 8.11.22. A new update has appeared, but it cannot be installed. TWRP does not see the phone memory. What could be the reason?
This will end up with your Data Loss so Backup Them.

Format data in TWRP This where you have to type YES to confirm If it ends with some red errors go back to main TWRP menu Reeboot To Recovery and do it again ->Format data. Now it should finish without errors and you storage should be visible again.

TWRP can not mount the phone memory. I can't make a backup and I can't make a wipe.
Can it be a matter of switching from the 7 version of Android to 8? twrp 3.2.1-0 worked without complaints on Android 7.1 Update from 7.1 to 8.1 (8.11.22) passed without any problems. Now there is another update (8.12.6) and my twrp can not update the system.
p.s.
I apologize if somewhere is unclear written, I write through the online translator.

Some More Info based on my case:

Mi 5X bought with Tissot A1 Bootloader Successfully recovered to original Tiffany Mi 5X Bootloader
Phone Is unlocked
No Root
TWRP Updated Successfully to 3.2.3-treble

After That no issues till 8.11.1 OTA, even haven't doing WIPE Cach/davlik, all works fine.
'At each update in TWRP LOG I got some partition missing/unmounted?? . Unfortunately I don't remember with one:( I didn't care since system was booting properly.

I wait for some more feedback till 8.12.6 and decided to give a try.

After updating TWRP i just hit OTA from Update Menu.

Of curse I get Black Screen :(

I Managed to enter Fastboot Mode and restore with:
"2) On computer install previous firmware via fastboot: ( https://androidfilehost.com/?fid=11410963190603853188 ) "
By XiaoMiFlash.

Remember to:
1. Unzip ROM
2. Verify that your device is visible in fastboot mode
(For those who have problems with entering in it with having black screen this is solution: HOLD power button until it vibes after that immediately release Power and fast hold POWER and Vol - until it vibes again. Wait 1-2 sec relese power wait another 2-3 sec with Vol - pressed after relese it. Connect to PC and check if fastboot mode is on - simply hit refresh button in XiaoMiFlash App your device should popup in menu)
3. use flash_only_firmware.bat option in right bottom corner
4. BE SURE THAT "clean all and lock" BOX IS NOT NOT NOT CHECKED:)

After Reboot Phone went back to normal state, with 8.12.6 update already Installed ?!?!?!? Weird?!?!? Fastboot Package was 8.11.2
After that i restart to recovery, wipe all data cache etc. and try to install Again 8.12.6 directly from TWRP
This time it went without any errors like before (partition missing etc.).

BUT... Black Screen Again:( Cash/Davlik wiped or not no difference)

Again....restoring via fastboot by XiaoMiFlash and 8.12.6 on board.

I think that with next update 8.12.13 it will behave the same :(
Did all the same and my phone booted up with 8.12.13 on it (the one I flashed and got black screen).
I have only one issue at the moment, my network signal is not stable and disconects all the time...
is there any thing I can do without full wipe?

The who are getting black screen try to make a clean flash with miFlash tool Chinese official beta Rom (don't forget to select only "clear all" otherwise it'll block the bootloader) and then install TWRP (3.2.3 trebele) and try again
