Firmware for fastboot (MiFlash) 10.3.6.0_PFCEUXM for Mi 9 Lite (pyxis)
in the file flash_all.bat deleted the top two lines:
fastboot %* getvar product 2>&1 | findstr /r /c:"^product: *pyxis" || echo Missmatching image and device
fastboot %* getvar product 2>&1 | findstr /r /c:"^product: *pyxis" || exit /B 1
run the modified file flash_all.bat through the command line from the folder with the firmware
And I am the owner of Mi9light 8/256)))
