Nexus 5 handsets have now started receiving Android 4.4.1 KOT49E, which happens to be the latest KitKat software update.
Even though it brings in quite a few changes, the most important one happens to be that it fixes the faulty camera on the Nexus 5. According to Google, the update "improves the camera with faster focusing, especially in low light, (allows) for faster white balancing, for truer colors, (brings in) the ability to pinch-zoom the viewfinder in HDR+ mode and also (allows for) less shutter lag." Owing to this, it happens to be very important for Nexus 5 users.
The guide below will help users to root Android 4.4.1 KOT49E on Nexus 5 with complete steps and how to flash ClockworkMod recovery on your phone. Super SU will be used as the rooting package and ClockworkMod recovery as the custom recovery.
