Google has pulled factory image files for the Nexus 4 from their developers resource page. At this time it is not clear exactly why Google decided to remove the files, but there are two main lines of thought. Either Google discovered a critical issue in an already buggy Android 4.2.1 build or the removal could be part of an effort to strip vestigial LTE connectivity from the handset.
The latter case is at least plausible considering Android 4.2.1 factory images remain live for Google’s other Nexus devices. A lack of regulatory approval by the FCC could be forcing Google’s hand in issuing a software update to make it harder for hackers to connect to North American LTE airwaves.
At the very least, the move is curious. The Android 4.2.1 software is already available on Nexus 4 handsets and removing the images, which serve as a method for restoring the device to its original factory settings, won’t do much to alleviate any issues owners are currently experiencing. Will Google return the Android 4.2.1 build as is? Or will we not see another until the next version of Jelly Bean is released?
