Well, got MIUI 11 installed on my Xiaomi Mi 9, the update was due and downloaded already. Yesterday the smartphone restarted and is stuck in a bootloop since then. Fastboot or TWRP is not possible anymore, because the smartphone is rebooting before it is accessing both of the mentioned.
The only other threads i found are MI 9 Stuck Loop Boot, no fastboot, no hard reset and the video MI 9 EDL MODE TESTPOINT BOOTLOOP FIX BY CEPHEUS ROM FLASHING
I found this tool as well https://xiaomitool.com/V2/ but i have not tried it yet. The smartphone is out of battery now, just asking for more opinions.
