Cool [Q] I need help reinstalling Android on Generic Tablet

Ok, so I'm an amateur Android root hacker and I was trying to install a DL'd Android file (volt) to swap external SD to internal phone staorage. I messed up. Now the tablet will not boot, as it gets stuck in the logo screen. I have tried ALL reset methods including recovery mode. When I try to select recovery mode, it only gives "NO" as as an option to factory reset. I have read online that I may be able to boot Android from an Micro SD card but this is where I get stumped. Can I use ANY 4.2.2 build, or is it device specific? If so, how do i find my build on a generic tablet such as mine? Here is what I can tell you about my tablet. It is a Tagital 9" A23 running 4.2.2. Here is title to the exact tablet on Amazon that may include some useful information. I can;t post the direct link because of my NEWB status.

TagitalŪ 9" Android 4.2.2 A23 Dual Core Dual Camera Tablet PC Play Store Pre-installed (Enhanced Version of A13)

As you can see, I'm only into the device for $75, but I would not only enjoy a working tablet, but also a solution to the original issue of partioned internal storage being all out of whack (502mb for device storage and then 4.8gb available, partitioned internal storage, not being used).

I apologize in advance if this is not the correct area to post, but I am a newbie. Please help!
