I have a Mi 11 Ultra, it all started because it came with the Chinese Rom and I went to install Global version rom, but I forgot to enable USB debugging.
Then it was only on the FastBoot screen, I watched a video teaching how to edit the file in Fastboot mode, but I missed a few lines and now it only goes to a screen without the image written:
