I'd like to leave the question here what this boot.img is.
I followed a few instrunctions already and everytime i try to get into recovery mode AFTER "successfully" installing TWRP Recovery, i just see a Xiaomi device with a cable beneath it. I assume i literally installed the TWRP Recovery, but i simply cant enter it. I have no idea what to do now, but the difference between your posts and the guides i've seen is this "boot.img". So i'd like to ask what it is and how i can get it. Thanks in advance
Edit: Yes, i unlocked the bootloader via the UnlockingTool of Xiaomi as well, it was successful
