Same problem here. I've downloaded a rom and flashed via SPFlash tools and I end at black screen. But once connected to usb the phone is recognized by the PC so it can be flashed if I have the right files. So if possible , someone with G610s , please make a whole backup and give us the file so we can flash . Please !
