My reciever has the rebooting problem. I tried loading the factory bin but it did not work. I have been searching for hours but can not find an updated 221 that does not reboot. Rumor is it is available somewhere...
I downloaded a ukr_221 that ends with an Ssfr , which is the v2 of the bin...the only difference from the previous version was the channel's list , the rebooting still there though, but it works just fine.
There are 5 221 bins, 2 by CS ,2 by UKR and 1 by leafs , all with the same rebooting issue but all working with A/R.
