Restoring Nuvision tablet stuck in boot loop. Can't find firmware.

I have:
My mom's NuVision TM800A510L (similar to Acer Iconia A1-840) stuck in boot loop.
I can get it into fastboot mode, and recovery mode waiting for ADB sideload.
ADB and fastboot recognize the connected device, but commands are ignored by the tablet.
I'm a novice, having once stumbled through a cyanogenmod flash.
Chromebook running Ubuntu, with Android SDK seemingly properly installed.

Goal:
To restore the factory OS, vanilla Android, or an alternate ROM. Anything to get it running.

I've tried:
Wiping cache, factory reset.
Can't find factory or custom rom anywhere. Customer service refused to provide it.
Following tutorials to bake a custom rom. They all seem to require a system for the tablet to start from. Creating one from scratch is over my head, unless there is a simple step-by-step somewhere.
Pulling partitions from tablet (failed command)
Pushing / flashing / SD boot of ROM for the Acer version of the tablet (format not recognized)

Does anyone happen to have the update.zip for this Nuvision device I can simply sideload? Or anything else I can try?

needrom does not have the rom for this model.

I have the same problem. I'm trying to use the ADB to make a ROM from what is on the tablet, but so far the only thing I can get to work ADB wise is the sideload, and that does me no good without a ROM :p
