I would avoid that option anyway. The touchscreen makes it own decisions about what firmware to upload to the controller, and in its current state, Luban will produce a package that the touchscreen will only accept once a day.
It will however look like its working, but will continue to flash the package previous package, not the new one.
I would recommend this instead which allows you to set a firmware version (to make the touchscreen think its new), or set the ‘force’ flag
