Hey Tom,
But, with 1.1.1 you had to, unfortunately. 1.1.1 was buggy, but could not be downgraded.
That’s what usually users should expect, however, this was not the case a short time ago with 1.1.1.
Usually it is never necessary to overwrite (re-flash) a Raspberry Pi OS installation (except if the SD card fails). Today, all Unixoid Operating Systems have smart package management systems. Usually unixoid operating systems have an uptime of monthes, even years, and are updated while they run – including occasionally necessary downgrade of a package.
But the ‘onefinity-firmware’ package is the only package on the Raspberry Pi system inside the Onefinity Controller that is not packed as ‘.deb’ package and therefore cannot simply be downgraded with ‘apt-get install onefinity-firmware=1.0.9’.
