Hi, just to let you know that this fails on my Nexus 7 (groupee) which has been upgraded OTA to 4.2.1 (not sure if this is a contributing factor though)
When I try debug it, it's clear that it fails to flash the CMW.
FYI, I was finally able to root my Nexus 7 using this : http://www.androidng.com/root-nexus-...dows-osx-linux
- I know, it's for Nexus 10, but amazingly, it works with my Nexus 7 too
Hope you find it useful.
