I tried to load the latest commando image onto 3 boxes but one wouldnt even recognise when cable was plugged into it using dream up the second box will only load some channels bbc1 bbc2 utv BUT NOT CHANNEL 4 OR 5 this is the same for a lot of the other channels possibly weak tuner. The third box flashed but when I plugged it into tv nothing happened,, The commando image at the start didnt even appear. Two of these boxes are new and were bought from ali express the other is a bit older. I tried different power supplies but it made no difference. Im now sitting with 3 boxes ready for the bin. Has anyone else had these problems and are they worth trying to get fixed. Any help will be greatly appreciated.
