Extracting 3d model from this generic file, and reimporting back

[Thawfeeq]

Hi,

Can anyone with the expertise please help me in extracting and reimporting 3d model from this generic file?

I was able to extract the model file (obj) from this generic file, using hex2obj. I can also edit the obj in blender. But what I am blocked is : how to convert/put back this .obj back to this original generic file?

I'm attaching the generic file here.. Please help me if there is some other way /script by which we can extract the model from this file, and put the edited model back to this format.
