Hi all...

I was on Android 11 xiaomi.eu and wanted to switch on 21.10.27 via fastboot.

The installation via windows_fastboot_update_rom.bat startet but stopped with an error.

Now the device is completly dead. I can not boot it in fastboot mode or recovery mod. It does not react with an key combination. If I pluged it in to the cable to connect with laptop or power... no reaction.

Any idea how to bring it to live again?

Thank you for any help!!

Did you try to leave the device charging over night or a few hours to see if it gives any sign of life?

The big problem is that if it doesn't boot into fastboot you can't even try to flash it using EDL mode...

thank you for the answer.

It just happend this afternoon. But as the battery was on around 90% I do not think that charging over night will help. When plugged in it does not show any indication that it is charging (not even getting warmer).

Nobody answered you!
You are in EDL state. check what driver you are connected to in windows manager. (You are surely on Qualcom qloader at best).
Contact unbrick.ru guys, they will reset your phone. (or any other authorized account)

1. With the same setup I did flash this phone with fastboot mode when it was new and the first twrp version was not released... so I do not understand why there should be a driver problem
2. How do I check it excactly?

- Is your phone connected to your computer . (check connected device in windows driver manager)
- Is fastboot state working?

- yes. its connected but no recognized by the pc
- no. as I wrote in the initial post... nothing is working. no fastboot, no recovery. not a single sign of life. just a dark cold dead piece of tech.
