Hi everybody!
One day I decided to reflash my charger. I downloaded an archive from this page: http://www.hobbyking.com/hobbyking/store/uploads/1019411227X1816993X33.zip
The archive contains DFU firmware and two firmware images: the original version 1.13 and a patched one, which does not require a balance connector. I chose the patched one.
I did it all as written in the manual: open the file, typed in VID 0x0000, PID 0x0001, click UPGRADE...
Briefly, I did it at work on a laptop with a bad USB port.
Well, it didn't go through. The laptop wouldn't detect it.
I've got a brick :(
