When is a Nexus not a Nexus? When you buy it from Verizon, evidently. It’s long been a gripe of Verizon Nexus owners that their pride and joy often receives the latest and greatest Android update months after the GSM variant. The good news is that whilst Verizon might be standing in the way of progress, the developer community has got your back (as ever!).
Shortly after landing on the AOSP servers, Android build JRO03L has been worked into a custom ROM prime for flashing to your Verizon Galaxy Nexus or Google Nexus 7. Early reports suggest that the build is seamless, offering the pure Jelly Bean experience just as Google intended. If spending an evening rooting and flashing floats your boat, you can click the link below to get going.
