On the 27th of June at the Google I/O conference Google announced the next version of Android, 4.1 Jellybean which will be released during the latter part of the year. However a functional version was released/leaked for the Samsung Galaxy Nexus shortly after the announcement was made.
Having a Galaxy Nexus lying around running with Ice Cream Sandwich 4.0.4, I decided to attempt an install. The owner of the (un)fortunate Galaxy Nexus, @edwardsuranga who was also a natural born risk taker, like myself, reluctantly gave me the device to hardbrick it even if it comes to that point. The Rom was packaged to a ZIP file and the installation was to be carried over Clockworkmod rather than using the fastboot mod. After a complete factory data wipe (Just to avoid any bugs that may occur because of the existing data), I installed the rom on the device.
Initial impressions were the same we saw on Ice Cream Sandwich 4.0.4 which is the last released update for this device, after the rom was installed it took several minutes to boot up as the dalvik cache was wiped clean prior to the installation. The Bootanimation has been changed from the coloured gear wheels to a glowing X sign.
