Hello again, maybe someone who has avh-x8700bt can export snapshot for me? I dont sure that it will help but need to try. All you need to do, insert only usb to port1, go to developer mode and click "Export snapshot image" I tried to do this on avh-x8600bt, it create folder KM500UW with file KM500UW-snapshot (262 080 Kb). I think that this is firmware snapshot, but i can not boot with this file, because i have no proper folder name for avh-x8700bt, file and dont know how =(
