Can't Boot after Download Rom With SP Flash tool

Hi Guys:

I have a Chinese android based Tablet The Specs Are:

Brand : Genx

Model: Crystal_Gx7_3Gi (genx tab 7)

Android Version : 4.1

The Tablet Website is: www.genxmea.com

there are other specs too.

I Tried to upgrade the system thought Recovery mode - cwm -

I installed a Wrong zip File and the phone went dead (cant power on ,no charging)

I tried a method with sp flash tool to download a similar rom from another tablet.

but sp flash tool gives me this error : S_DA_SETUP_DRAM_FAIL (3002)

I Can provide images of the mother board also.

any help would be appreciated .
