Toshiba AT100
Android Version 3.2.1
kernal version 2.6.36.3-00020-g98efb64

When I try to download an app or try to install updates I get this error

"RPC:S-7:AEC-7 LDPU-FAOG-BOFHC"

I contacted Toshiba support and they basically told me to get a new tablet.
I joined a forum for the Toshiba tablet and they referred me to a Youtube video for upgrading to a newer android version. However, with the error I can't do it. Any ideas?

Thanks.
