Last week we had the Android 4.4 KRT16O Factory Image released for download. Now, a new build has been announced and Google made it available for its Nexus devices, the Android 4.4 KRT16S.
Besides the OTA Update, the Factory Image of this new official ROM has been made available for download.
In case you don’t want to wait for the Android 4.4 KRT16S OTA Update to arrive to your device, then you can always use the Android 4.4 KRT16S Factory Image files and update it yourself manually. However, remember that such Factory Image installations will remove all data from your device in the process.
Installing a Factory Image such as Android 4.4 KRT16S is not that hard, but you need to know that you will need to unlocked the bootloader. Unlocking a bootloader for a Nexus device means that all data will be removed in the process.
Android 4.4 KRT16S Factory Image can also be used by custom ROM developers to build their own versions of KitKat ROMs such as CyanogenMod, Paranoid Android, AOKP, Carbon, OmniROM, SlimKat (former SlimBean), etc.
KRT16O to KRT16S Update / Factory Image release happened due to some errors that developers found after updating the first time from Android 4.3 to 4.4. After updating Nexus devices from Jelly Bean to KitKat numerous users lost access to encrypted disks, which is a serious bug. This was found only on Nexus 4, Nexus 7 (2012 / 2013) and Nexus 10 devices.
Nexus 5 will not receive KRT16S firmware update nor factory image, as this model didn’t need to be updated to KitKat from Jelly Bean like all the other Nexus phones.
There are several other changes pushed with this update: backup service supports dynamic registration, fixed 2012 Nexus 7 3G radio, Nexus 4 gets a pre-build kernel which adds an updated WLAN driver and several APN tweaks for different carriers. If you spot any other important change then you can tell us in comments.
So, if you don’t want to wait for official OTA Update to be pushed to your Nexus, then you can download the KitKat factory image and use an alternate method to update your device.
