First, note that this is only my second time dealing with rooting a device. I am technical, but not really that familiar with Android internals. The other one was a Galaxy Nexus
I initially tried the instructions at Figured how to go from 3.2.1 (No OTA found) to ICS!!!
Which instructed you to use the Thor Recovery, but that wasn't working, which is what prompted me to go for alternatives
Having said that, I think I just bricked my tablet when I tried rooting it. Should have left it alone .. BIG SIGH.
