Problem With New Release 7.7.13

[Xori22]

hi,
I have tried to update from 6.12.22 to 7.7.13
I tried to update from the updater, it boot into recovery but failed after couple of minutes.
from then, my phone cannot boot. it only boot to MI logo.
I can't access TWRP.
I can get in fastboot mode.
there is a way I can save my phone?

You can always save a Xiaomi device...I believe at this point you need to downgrade to an earlier Chinese version using EDL mode since you cannot access recovery or fastboot mode...take a look at this guide...I have used it several times successfully to revive my MI4c devices..

From here you can take an OTA update and it will relock your bootloder...then unlock it via official means and you are back to where you started...flash TWRP ...install Xiaomi EU ROM....

hi and thanks for the answer.

I followed this guide, it's start good but it fails to flash the ROM.
after 327 (and the green bar is almost done) I get an error "the filename, directory name, or volume label syntax is incorrect. (0x8007007b: max buffer sector is 256 "
(using win10 64bit)
and now my phone just black screen. not even fastboot.
