Just wondering if anyone could help. I am on 7.0.1 firmware and using the sx pro dongle, jig and license. I formatted the microsd card with exfat and installed boot.dat and sxdumper.nro but when I go to boot custom firmware, it just goes to a black screen. I tried both 2.5.3 and the 2.6.1 beta os that are listed but no difference. I've seen other threads with similar problems but I'm lost on where to go from here. Thank's a lot
