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, but what if you want to keep that unblemished piece of Ice Cream Sandwich for posterity? You could download the AOSP files, but you'd be missing some vital ingredients from the official factory images. Thankfully, build IMM76I of Google's mobile OS is available to download in a simple archived format. With this release Big G 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 a safety first kind of guy or gal and like to keep a simple factory reset kit handy (you know, just in case that latest CM9 nightly doesn't work out so well), head on over to the source link to download the untainted Android images.
