Hi everyone,
I flashed the recovery rom it worked, but then I cannot flash the rom due to error 7: package name "cepheus", this is "xiaomi 9". Then I turned off the recovery, and it returned to fastboot mode and keep loop in fastboot. I cannot turn off, and when I flash the recovery file again, it showed "failed to load/authenticate boot image: load error" (as shown in the picture). The phone still in fastboot and cannot turn off. I tried all the hard button (Volume + and power/Volume - and power) all not working.
How can I fix it?
Thank you!

EXACT TIME 10.00 TO 13.00 MIN

Reason for boot loop...

TWRP LR.TEAM

Maybe you get some idea or IDENTIFY your mistake....

When I write adb logcat, it says waiting for devices but my phone is already connected. Unplug and plug again but still "waiting for device"

clean the memory from fastboot with the command:

Fastboot format userdata

This command will erase the entire device. put the ROM into a USB to flash it via otg


Enter enter TWRP and repeat the installation process, if it does not go or it starts starting too long do all the wipes. included system "I do not recommend it but I do not start until I did this wipe"
