Flashed my box using Ipab step by step guide. All sly channels fine but during the cable set it finds 972 video 97 radio then a sign pops up saying cant read data. Done this twice now as i flashed my box again as when i changed skins first to cable, screen just blank and no epg, then back to sly all channels blank but epg working. Checked my line and that couldnt be found, so reflashed and all sly working fine but same cable problem. Any advice please.
