As quickly as Samsung upgraded the international version of the Galaxy Nexus phone to Android 4.1, we obviously hoped that the Sprint and Verizon branded models were to follow suit not long after. That hasn’t quite happened, unfortunately, and both phones are still waiting to officially join the Jelly Bean fun.

Sprint and Big Red have both promised to roll out the update in a matter of weeks, but if you feel that you simply can’t wait anymore, you do have a few options to help you perform the upgrade yourselves. For Verizon’s 4G LTE-enabled Nexus, the latest such option comes from XDA senior member mmuzzy, who has posted an AOSP build of Jelly Bean on this forum thread here.

This custom ROM is not very different from other firmware updates you might find online, but it is reported as being stable, bug and glitch-free. It’s also “pure AOSP” (Android Open Source Project) without any kind of new customizations or tweaks, so it should look and feel exactly the same as the upcoming official JB update.

The flashing of this ROM shouldn’t prove too complicated either, even for those of you who don’t have much experience in the field, but naturally the usual set of precautions and warnings apply. You’ll need to root your device first and foremost (more details and a useful all-in-one tool here), and then follow mmuzzy’s simple instructions over at the XDA thread. Keep in mind that you’ll almost definitely be voiding your phone’s warranty if you decide to install this ROM (or any other custom one, for that matter), and don’t forget to perform a system backup before starting the root process.

If for some reason you’re not fully comfortable with this particular JB port, but you still want to treat your Verizon GNex to some Jelly Bean goodness, we recommend you try this Vicious 4.1.1 build or the official CyanogenMod 10 port. Any way you decide to go, please be very careful and don’t forget to have some fun. Also, don’t be shy and drop us a comment below if you have anything to say about any of our three recommended Jelly Bean custom ROMs available for Verizon’s Nexus.
