Android 4.0.4 factory images hit the web for GSM Galaxy Nexus
Sure, pushing builds of Android 4.0.4 out over the air is great, what if you want to keep that unblemished piece of Ice Cream Sandwich for posterity? You could go about with downloading the AOSP files but would mean you’d be missing some vital ingredients from the official factory images.
But thankfully, build IMM76I of Google's mobile OS is available to download in a simple zipped format. With this release Google is also introducing a second version of its software. In addition to the standard "yakju," there's now "takju," which includes Google Wallet and the necessary support files.
If you're too much thinking and not enough action, safety first kind of person and like to keep a simple factory reset kit handy (just in case that latest CM9 nightly doesn't work out so well for you), head on down to the Android official site for the untainted Android images.
