The official Android 4.4 KitKat update is expected to roll out for the Nexus 4, Nexus 7 and Nexus 10 very soon.
However, owners of those older devices who are not willing to wait can install the update with a new set of ROMs.
Nexus 4 users can access the ROM through a link provided by Android Authority.
Anyone downloading and installing the new firmware on any of these mobile devices should be extremely cautious since doing so can void their warrantee. Backing up data and following steps perfectly should result in a successful installation.
The official Android 4.4 KitKat update for the Nexus 4, Nexus 7 (both models), Nexus 10, and Google Play editions of the Galaxy S4 and HTC One will receive the update in the coming weeks.
Android 4.4 KitKat was introduced by Google yesterday alongside the brand new Nexus 5 smartphone.
The software is designed to be installed on a wide range of devices including older models that only have 512MB RAM.
"KitKat streamlines every major component to reduce memory use and introduces new APIs and tools to help you create innovative, responsive, memory-efficient applications," said Google on its developers website.
The software is designed to protect system memory from apps consuming large amounts of RAM. Android will launch the services serially, or in small groups in order to avoid peak memory demands.
KitKat will also add new capabilities to NFC along with the ability to print any type of content over Wi-Fi or cloud hosted services such as Google Cloud Print.
