Just done online update (not a couch flash), needed to reconfigure the hybrid tuners to DVB-C. Now got Cable channels working but ABM does not detect a Cable tuner. Going into providers does show terrestrial providers despite no tuners setup for terrestrial, but not cable providers and trying to run an ABM scan reports the no NIM's found message
Edit: Just tried a clean install without restore and the issue persists. ABM is reading the tuners as Terrestrial even when configured as Cable
