I have big problem with upgrading my bird, after exactly 12:15 min it fails. I have tried at least 40 times and tried all possibles ways but still fail. I have been talking to the support and they talks about an gs_ofdm.bin file, but I can not find that any where, it should be hidden somewhere.I have succesfully updated the RC but now I want to downgrade it. If I put the 1.1.9 FW on a USB stick and put it in the RC nothing happens and I can not find where to do it thrue the app. Can anyone help me please?
