        I'm stuck on the first step in getting to install UnbuntuTouch on my Lenovo x606F, the dpwngrade from Android 10 to Android9 I am not used to Android and have never tried to reflash an Android device before; all the threads I can find on the topic seem very specific to particular versions of flashing software and device.
        So, I am using

        1. Manjaro Linux (I don't have a Windows system)
        2. SP_Flash_Tool_v5.2152_Linux (I can't use the most recent versions of the flash tool, as they expect an xml file for download, instead of the scatter.txt file that Android 9 has)
        3. Lenovo_Tab_M10_FHD_Plus_TB-X606F_MT6765_S000009_210526_BMP as my Android9 image.

        I can't get the Flash Tool to write anything to the tablet at all; I have tried both starting with the tablet off and holding down volume and/or power while connecting the USB, and using 'adb reboot fastboot' after starting download on the Flash Tool. Whichever I do I get the same result:

        ./flash_tool.sh
        QGtkStyle was unable to detect the current GTK+ theme.

        The tablet itself reports that it is in fastboot mode.

        Any ideas?
        Thanks
