More timid users might want to sit this one out, but for everyone else, you'll be glad to know that a pre-release build of Android 4.1 is now available for installation on the Galaxy Nexus from Verizon. Many of you are likely aware that custom Android builds such as AOKP and CyanogenMod have provided an early taste of Jelly Bean for a while now, but this time around, the flashable zip files are available directly from Google -- that's right, this is pure AOSP. Specifically, users will be treated to build JRO03O, which is an incremental update over the previously released binaries. The caveat here is that the software has yet to receive certification from Verizon, and you'll need to unlock your bootloader to join in the fun.
For experienced users who've already installed a custom recovery utility such as ClockworkMod Recovery, the process couldn't be easier. Naturally, if you're already on a custom build, you should perform a data wipe within the recovery utility, then install the IMM76Q package and then flash the JRO03O build on top of that. Regardless of your experience level, anyone with the proper motivation should be able to pull this one off. Those starting at square one will find a complete list of instructions at the source link below.
