I accidentally erased the os, and recovery mode wont work,

I have an odd computer with multiple users, one time of many I was doing a routine format just to speed things up but forgot to unplug the tablet and was using "dan's boot and nuke" to format the computer and told it to format everything (more specifically 'auto-nuke') and now the tablet refuses to work. HELP?

I have tried both forms of recovery mode and am now unsure as to what to do.

just to let you know, the red power light is coming on when I charge it so it's not(?) bricked...?
