There’s no such thing as too many Android 4.4 KitKat roll-outs. Shortly after Motorola officially confirmed the Verizon Moto X to be the first to receive the update followed by the whole Droid family; the Google Nexus 4 OTA to Android 4.4 has also begun. The new update hit the major AOSP and Nexus channels, and it brings the build number from KRT16O to KRT16S. The major Android 4.4 update applies to the Google Nexus 7 both original 2012 and 2013 models as well as to the Google Nexus 10. According to Google software engineer Conley Owens, ‘The source code for a bug fix build (KRT16S) is being pushed to KitKat-release and will be tagged as Android-4.4_r1.2. This release is for Android 4.4 KitKat available for Nexus 7, Nexus 4, and Nexus 10.’ and the binaries are repository added to the Nexus.
Google developers added in their page a rich content of binary image files provided for use in restoring Nexus device’s original factory firmware. You can check out the contents HERE.
Unfortunately, Google Nexus 5 is still on KRT16M, and respectively the Nexus 5 images haven’t been updated yet. The new built hasn’t been announced for that device, but that is most likely to change soon. Nevertheless, if you own a Nexus 4, any variant of Nexus 7 or Nexus 10, your KitKat update is already waiting for you, featuring major bug fixes related to the APN settings as well as the so called ‘stop-ship bug’. Al Sutton, a developer, stated in his Google account ‘he vold change could have left encrypted devices undecryptable if the user entered the wrong password after an update, because the key generation function could be changed before the correct decryption password was entered leaving a mismatch between the generated key and needed key.’ This pretty much explains the delay of the update as the engineers were obviously working on fixing the bug.
