PMOS Community Edition phones

[bcnaz]

Strange to me,  back when I first got my Brave Heart near the beginning of this year,  the UBPorts OS worked ok on my phone.  But when I went back recently and re-tryed those same releases they do not work now ?
Same thing with the early Mobian releases,  those all worked when they came out.
It would appear (to me anyhow) that there must have been some firmware updates that do not play well with the older operating systems ?

Reverting to an older release should restore the capabilities of that release. Don't know of anything that would change that.

I am not an expert on the software, but the fact that it would not "Revert"  leads me to think the firmware 'may' have been changed.  ?
  If an operating system that released in March or April worked (talk & text) when it was released,  but now the same March/April release does not work ?
(When I first got my Brave Heart phone I was mostly trying Ubuntu Touch.)

  I am just at a lose for any other explanation..  ?

( I did not write down the dates, so those are approximate.)
