Ok , b-70 was the old flash those boxes used, now you have to flash to the new b-80. All new bin will only work with the b-80 flash. The last bin for the b-70 was the 367. After that bin all new bins will only work with the new b-80. So i sugest that you flash your unit with the b-80 using latest loader and then load latest bin 319.
