FYI,just because it doesn't have tunes loaded on Open Flash Manager doesn't mean it's unmarried. I've been through this nightmare before and it sucks,but you have to make sure that nothing is still loaded onto the device itself. Even though it says on the PC that the device has never been used,it can still have information on it if it isn't unmarried correctly.
I'd urge anyone that's selling an OFT to take a picture of the actual information on the tablet itself first,then from Open Flash Manager,to make sure it's completely unmarried.
Just for some reference,here's what my issue was.

Not trying to scare anyone off,or make the seller look bad. Just want to make sure no one else has the same issue that I had. GLWS.
