What is the option to choose to run the Tablet PC in Uberoid 7 VIA8650 Cell Phone model: M7000?

Hello guys, I'm trying to update the ROM on my tablet PC 7 VIA8650 phone function Model: M7000, and can not find the correct model number in Uberoid. Has anyone managed to upgrade to this model of tablet?

When you say update, do you mean you are rooted and want to use a new custom ROM, or do you mean to officially update it from the manufacturer?

I wanted an official ROM manufacturer, you are there to pass me the link? Because this tablet is not telling what frabricante only show the name Android in the back ..
