Build Number: JOP40D.WW_epad-10.6.1.27.5-20130902
I am trying to unlock so I can upgrade the OS however I tried the unlock v8 and comes back with a error in the network connection. Can you assist in unlocking and provide instructions to install a more update version of Android? The tablet was not used very much and basically sat in storage since purchased so I would like to get it running again. Thanks
