Zebega STB from handan having diffrent software versions i.e starting 103,134,144,152 and 154 . The 103 and 134 is not ci interface and remaing are ci interface. 103 version have a quality software when we try to tune the stb the signal strength and signal quality bar increase similarly but all of version does not support the same even 152 and 154 always showing full singal strength. Its very difficult in 154 when we try to tune stb the stength always showing full. Can any one help whether we can upgrde or degrade these software . I listion the astra having ota for zenega . can these eprom can load that firmware or can we down load T-online software on zenega as T-onine using zenega brand ?
