There is NO safe autoroll for ALL Ultra's..there is a new 101 bin which allows manully input of keys,its 282 and 256 combined,BUT that file has many bugs!.there's a bangs 17 Jan Ulta bin with the new keys in it that is safe for all ultra's..
All the Ulra's differ based upon which chipset is in them and when made..some files work on older,and some only on newer..and many will kill the Ultra..
There is a 256T bin that allows U to input your own keys manually..its a Pansat bin that is safe to use in the Fortec Ultra...its at dsscommunity.co*m ..Forums...Fortec area..
