You can probably also boot from the SD card, unless the SD card slot
is damaged.

Based on what you say, it looks like you want to restore Android on
your tablet. This is usually done via http://linux-sunxi.org/LiveSuit
Naturally, you need the right firmware image for your tablet. Good
responsible vendors are providing such recovery images from their
websites. Maybe people from various Android forums can help better?
This mailing list is primarily dedicated to running GNU/Linux on
Allwinner hardware.
