if you see that blue screen you need to touch the pins again with a screwdriver and you'll hear the sound, I think it is better to use Product_Toolsv2.8 to upgrade firmware.It can write the selected firmware easily to the flash even if the firmware is invalid.İndeed there is problem in original fw upgrade program so I prefer that one.Thanks all of you and sorry for my poor english :roll:
