Cannot flash Gionee M3 with SP Flash Tool

I am using LMDE 2 (Debian Gnu/Linux) and trying to flash stock lollipop firmware on Gionee M3. I've Sp flash tool version: 5.1532 for Linux and also set up adb and fastboot perfectly. In adb device is listed authorized everything fine. But, when SP flash tool is invoked and scatter file is loaded, it is stuck without any change. I've gone through this thread and modprobed cdc_acm module and in ~/.android/adb_usb.ini I've added "0x0e8d" also.

I connect with the phone powered off and the device id shown is:idVendor=0e8d, idProduct=2000
