For months now, users who wanted to root their Logitech Revue GoogleTV unit were either forced to use hardware modifications or do without. Now, though, Android hacker extraordinaire Dan Rosenberg has found a way to do it completely through software. There's only one problem: it's both extremely difficult and risky. Still, if you're up for a challenge, this one's for you.
This hack uses an exploit called nandpwn, which is explained better on GTVhacker than I could ever do:
A local privilege escalation exploit for the Logitech Revue that leverages the ability to map the hardware registers of the NAND flash controller in conjunction with a Linux kernel information leak to clobber kernel memory in a way that allows gaining privileges.
