Motorola is taking their sweet time in getting ICS rolled out to their devices! Ice Cream Sandwich was made available almost half a year ago. Motorola did release an upgrade rollout chart a few months back. It however did not specify any time table as to when it would have the update out. The Atrix and Photon are scheduled for Q3 2012. Hopefully the ICS update comes out before Jelly Bean Android 5.0! Sometimes it makes you wonder if we will ever see the release on these Motorola devices. It is always nice to see a leak here or there to at least remind us that the manufacturer is still working on it. DroidForums member Dave12308 found a new update in the Cheescake app labeled 5.5.905. This is not ICS, In fact it looks like the only change here is the CDMA radio, but this is the latest version of GingerBread available and is hopefully a step towards an ICS release.
In the past Cheescake updates were notorious for leaving folks stranded on a leaked build with no easy way back to the official upgrade path. However this leak appears to be pretty safe. Dave12308 says that not only is it Rootable via Motofail, but you can also FXZ back to .902 to get yourself back to the update path.
To install just download the file, drop it on your sdcard (no need to rename it), boot into stock recovery, and choose the .zip. Pretty simple.
