Once the porting guide is up tomorrow and I have some time I am going to work on getting the Nexus 7 image working on the TF700. I tried getting it working on my Nexus 7 but all I got was a soft brick. I am running PA 3.0 on it so that may of caused it because I think the installer is expecting a stock rom to be installed.
