“Soon”, yet just a phrase but a deadline for those who owned nexus devices other than the Nexus 5 which came up with KitKat out-of-the-box. Yes! We’re talking about the worthy and powerful Nexus 4, Nexus 7 & the Nexus 10. The Nexus 5 & KitKat 4.4 release took place a while back and we already got it covered and explored and guess what just showed up! The factory images and binaries for the rest of the Nexus devices are now live for download and flashing, which also means that the official Android 4.4 OTA rollout for the rest of the device series will now take place.

Not all of us like the OTAs or dirty updates, some of us are really good to handle things manually. So, here we’re today to guide you to Install KitKat 4.4 Factory Image on Nexus 4 (KRT16S).

Before we hit the instructions, we would also like to remind you of the AOSP 4.4 build that was available by ParanoidAndroid, just in case you are a custom ROM fan.

  4. Connect the device to the PC via USB cable

    fastboot erase cache
    fastboot erase recovery
    fastboot erase system
    fastboot erase userdata
  7. Flash the bootloader, type:
    fastboot flash bootloader bootloader-mako-makoz20i.img
  8. Reboot the bootloader (This is necessary), type:
    fastboot reboot-bootloader
  9. Flash the radio, type:
    fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.84.img
