Default [Q]Ematic Eglide Prism rom troubles

I have an Ematic Eglide Prism. The tablet originally came with Android 4.0, but due to a mistake my friend made the tablet quit working (which is why I now own it). I managed to fix it by using LiveSuite to flash a stock image (Cyclone Astro+ 4.2) and it works, aside from the tablet not rotating automatically. So I decided to try to install an AOKP and CM10 rom I found for A10 processors onto it. However this did not work, and both roms get stuck at the boot animation with the same errors. (I'll post them after my next attempt to fix the issue) The errors say something along the lines of the dalvik-cache missing. So I tried to create it only to find that /data was "read-only". Using the mount command via adb shell revealed that data wasn't even mounted, on either rom. I've been trying everything I could think of to get these roms to work, but the only one that seems to work is the stock Cyclone Astro+ rom that is flashed via LiveSuite.

Anyone have any ideas?
