I recently unlocked and rooted my nexus. I am very interested in flashing ICSourcey 2.0. 1. I was curious, if I were to flash a custom rom what's the behavior when verizon pushes an OTA? 2. I am always super careful when it comes to doing this stuff and read the instructions/reviews/FAQs nine times before performing anything but is it possible to irreversible mess anything up? EDIT: Haven't used this forum in a while, look at the device I have listed.
