[Sony Ericsson Xperia Neo, Pro] Engelstrommeln:
Hello

I have big trouble. I'm trying to flash ics on my haida and when is flashing "system.sin" phone automatically disconnects. I'v tried to flash gingerbread but flashtool doesn't see any of this version. Phone when is connected to computer is connecting and disconnecting without any my initiative. It looks that.
