I have the 501 update from March now and saw that there is an update to 506 now. I thought I would try out forcing an update, so tried it yesterday evening, it did its thing but when I checked it was still on 501.I thought I would try again this evening, it did its thing again and I still have 501 it says. Everything on my end as far as signal and internet checks out as ok. Any ideas as to why I can't seem to force the update?
