I had the same problem, I couldn't even get into testmode it would reboot copying the files, what I did was update 2.0...again, the unit was already at 2.0, it still wouldn't boot up but it would endlessly load, but then it would let me get into testmode, now I'm just waiting to finish downloading the files from gsxr 1k and all should be well I believe, I'll update you guys in about 30 mins
