My device hard bricked a week ago and I spared a lot of time searching for the right scatter files and rom.
The problem was that the preloader was corrupted and the only thing that showed that device is not entirely dead was that it was showing MTK USB Port when connected to computer.
At the end I read back the firmware from another G610S-U00 and fixed my device using SP Flash Tools.
It installed the correct preloader and recovery, which was enough to power on the phone, enter in Recovery mode and flash another Firmware G610-U00_B127_LF_V1.zip from my SD card.
Very good explanation of SP flash Tools for flashing ROMs thanks to DR_MOOSAVI can be found here: http://forum.xda-developers.com/show...2587&nocache=1

!Flashing ROM has some risks of bricking your device. Use this files on your own risk.
