Update:- Having bricked this 'clone' box, i set about the fix with the ERom Upgrade Tool, Null modem cable and Prolific PL 2303 HXD USB connector. the first couple of attempts I was getting a 'STB memory error' so, thinking of the reapers methods, I changed firmware to an older version and that loaded OK. However, this time when the box booted up it got to 93% then stuck showing 'E001'. I tried again, with the latest firmware and it all went according to plan. ticked no. 15 in the satlist, downloaded latest TP list over the network and everything is good again!
