Recently Google released KitKat 4.4.3 update for Nexus 5. This update didn’t bring any new features but was aimed at providing bug fixes and enhancement patches. This update is available in the form of OTA (Over-The-Air) file. Since it is release as OTA, it won’t be released for all regions at once but in gradual steps. This means while some regions will get update first, others will have to wait for a couple of days for the update to arrive on your Nexus 5.
Also, if you are running any custom ROM or have a rooted device then too you won’t get the official OTA update notification, even though it might have been released in your region. In any case, you might want to Manually Install KitKat 4.4.3 on Nexus 5.
The procedure followed in this guide will work even if you have a custom ROM, Kernel or have a rooted device. But this will erase all your user data and will unroot your device. Therefore, you must make a backup of your important data and again try to root your device after installing the OTA.
Since OTA update is an incremental update, be sure that you are running on the latest KitKat 4.4.2 version (KOT49H) on your device. Otherwise this procedure will fail.
