hi everyone, i have a zgemma h9 twin. i have a problem. I updated the device from telnet. reboot.. home screen opened menus bouquets came, but black screen comes when you select channel. cccam server working but no broadcast. This is also the case with fta channels. then I did zero setup, I set it but it didn't open again. 2 days later, the update came, I updated it and it improved. I watched it for a while. later The broadcast freezes again during the match, which lasts for about 1 week. It feels like watching a match on iptv, it freezes after a certain time. I use my ccam to oscam. I updated it, maybe i hope fix it, I updated it again, black screen came. I couldn't keep the order in the device. I would appreciate if you help.
