Hmm, not sure then - maybe try md5sum on the firmware that dmesg shows
loading on each then if different backup/copy over etc.

I am just a user so don't know what's different between 3.16 and later.

One thing I noticed at one point when setting mine up was (after
unknowingly breaking a splitter) that with the degraded splitter I could
get working/not on some T2 muxed by flipping the lna on off with the
option available with dvbv5-*.
