[Q] Failed to flash system.img (Data too large) (Qualcomm msm8610) topic

Hi,

Device : MANN Zug3 (Qualcomm msm8610)

My phone was bricked after flash system.img. Now the only way I can access my phone is fastboot. I tried serveral way to create & modify system.img then flash to system partition using command

"fastboot flash system system.img"

It got chunk file error because max download size is about 512MB but my system.img (I got system.img by porting from the phone using "dd if= of= command") is more than that so I tried

"fastboot flash -S 768M system system.img"

then i got "Failed : data too large"

I also have stock rom but it was separted to 13 files with name

systm_1.img
systm_2.img
systm_3.img
...
systm_13.img

But I dont know how to flash them.Is there solution to flash these files into system partition?
Can anyone help me to unbrick my phone please .....
