Root Root Tool for OTA ICS

There is now an official root tool for the ICS 4.0.4 OTA update and it works great. I used it last night and it really could not be easier.

[root tool} Toshiba Thrive ICS 4.0.4 root tool

Root using this tool, flash dalepl's ICS ROM on to the Thrive, clear out the junk you no longer want and you will be a happy camper running a clean ICS on your Thrive.

Or get more adventurous and look at the many custom ROMs.
