No, copying all the info from one tablet to the next will do nothing. You need to flash the original stock.img and ROM. Try to find through manufacturers website or through Google search to see if someone posted in another site for this tablet.

Dont believe so. The files are put there to run the tablet but the code to tell where things to install, etc are not on the tablet. Google search for anyone how does development or has access to the zip from manufacturer would be your best bet.

I tried searching through my file explorer for location of the boot.img file but no luck other than through CWM. What I'd recommend is, if you have custom recovery, "backup current ROM" and then extract the boot.img from a file explorer to add to what you need to reflash the ROM. I believe the boot.img is made via the recovery backup and I wasn't able to find any by Google search.
