[Q] Unbricking Acer A210 JB

Can you tell me how to Unbrick Acer A210 US tablet?

I was trying to root it, got stuck in Sideload while in recovery mode. I foolishly turned the thng off and now upon reboot ther display is stuck on JB version and unlock mode.

Can you please Help?

My only other alternative is to try and get a replacement or refund from my vendor. (Which would work, but I'll still be a stupid noob).

Thanks.
