thanks for the pointer...and i do totally understand the images are experimental. I found a few references to the SDUPdateTool on this site but nothing that leads anywhere....might you have any further info on this and what i need to do with it ? I am downloading the original q7 firmware in the hope that this might help somehow, though the device just doesnt seem to be booting at all so i am not confident it will get my anywhere on its own....
