Got some 'vendor' error while flashing.
Have to reinstall stock rom via odin.
Recovery via TWRP doesnt work (also vendor error)

Hi, I'm using this rom and everything seemed to be fine until I got an unexpected reboot and noticed that after this, my keyboard went back to the stock one and fleksy, which I had installed and set as my input app was disabled. Any way to fix this?

    I really liked this ROM but couldn't continue using it because I kept getting random reboots too.

    Edit: I reinstalled and it's working well for now.
