I seem to have hard bricked my 9T after flashing the MIUI 11 rom from xiaomi.eu. I think culprit is a totally botched/corrupted boot loader and I have no idea how it happened. I've tried reflashing back to stock through stock image .bat files, but no dice. It flashed everything but the device still refuses to boot past the MI screen. If I try to boot into TWRP, my device gets stuck at the TWRP splash screen, no matter which version it is. Does anyone know what I can do or try at this point? Thanks.

So do I, first time I successfully instal first beta v25 miui 11, and than when the v26 comes, stupidly, i flash it from twrp, it tells me that i succeed installing that zip, and than i wipe art and cache and reboot system, but what next i know, my phone brick, i can not instal anyrom, from mi flash tool, or from anywhere. I did everything and still can not fix the problem.
Anyway, you still can enterin TWRP UI, after waiting about 10 to 30 minutes, because after intalling that rom, automatically your data format change from ext4 to f2fs, and twrp will need a lot of time to read your disk.
But, even after doing anything in twrp, still can not make my phone successfully boot into system.
And theres moun I/O error everytime i tried to wipe everything, or fix disk, or change disk format. Everything... and i just dont know what to do anymore.

So may be you can wait patiently until you can entering twrp ui, and please lemme know if you know how to fix this problem

I had the same problem with a miui 10 weekly beta but unfortunately I wasn't able to fix it but lucky me my phone was still in a return period so I returned it back to Amazon and got my money back since then I have always stayed away from beta ROMs . I tried everything but it wasn't booting pass the mi logo as you said

did you really reboot it using adb reboot twrp? and reboot system on twrp using twrp cn version?

This LR. TEAM is twrp cn version right? And in fact, this version hardly booting to twrp ui version after this problem, easier to entering twrp ui with the ugly themed greek version

This makes sense as I remember trying to boot into stock recovery early in the morning. I woke up and it finally booted, but the recovery was in Chinese. I will give 4PDA TWRP about an hour and see what I can do. Thanks.
