Help with os issues and alternatives

So i have lenovo n42 (reks) flashed chromebox uefi and installed chromeos flex, sound support was missing, tried fydeos 3 or 4 times, sound and keyboard support both was missing, i searched for ways to revert it so made a bootable linux mint usb and went into terminal from their but got to the dead end of eol, so any suggestions on how i can find a chromeos alternative with android apps, or make the chromebook useable again somehow, help will be very appreciated

You can install Android apps on Linux with Waydroid.

Waydroid requires Wayland, so switch to a distro that uses a desktop environment with a Wayland compositor, i.e. GNOME or KDE.
