Earlier today we told you that a lucky XDA member received a Jelly Bean OTA update for the Verizon Galaxy Nexus. You can download the test build and install it yourself, but you have to go back to stock (build IMM76K) to make it happen. Just follow the steps below.
- Make sure you’re running stock (If you’re not then you can use WugFresh’s Nexus Root Toolkit to restore/install stock)
- Unlock the device and install a custom recovery (Wugfresh’s Toolkit can do this as well)
- Flash the IMM76Q Package via the custom recovery
- Flash the JRO03O Package via the custom recovery
