Try new images later on, I guess, when all the updates are integrated into PurE2 v. 6.5, since the process of building new images for all STBs takes time, as our coders tell us:
Streamlord
StreamlordTV
LookMovies
LookSeries
xHamster
Iwaatch
Mediaplayer2 (fix BSOD?)
pManager....
Simple SW update should be safe for recent images but be careful, if you haven't done it for a while and have many packages to update...
In that case, doing it all from scratch, a new flashing is, of course, safer...
