Some of you must have got the OTA upgade and others are a bit furious as they aren’t getting their beloved Kitkat upgrade on your Nexus devices. Well, the ones who haven’t got their update yet, we have a safe and official way of you upgrading to your Nexus device via a Kitkat manual upgrade . The below steps will work with any of the Nexus devices which includes Nexus 4, 7 or 10. Before you do any of the following step, you need to enable USB debugging on your Nexus device. To enable USB debugging, you have to go to Settings and open Developer Options, in case you don’t see Developer Options, go to About Phone/ Tablet, tap on Build Number repeatedly and the device will tell you that you are now a developer, go back and you will see Developer Options and you can enable USB Debugging.
- First, check if you have the latest Nexus 4 driver on your Windows machine.
- Secondly, download the update file using this OTA update URL – Here are some of the KitKat OTA Update URLs for you which include the Kitkat update file and the minor upgrade which KitKat received recently: Nexus 4 (from JWR66Y) (from KRT16O), Nexus 7 (2012) – Wi-Fi (from JWR66Y) (from KRT16O) or 3G (from JWR66Y) (from KRT16O), Nexus 7 (2013) – Wi-Fi (from JSS15R) (from KRT16O)or LTE (from JLS336I), Nexus 10 (from JWR66Y) (from KRT16O).
- Now, download the Android SDK based platform-tools.rar file which contains the necessary ADB files, which you will be needing to apply the update.
- Extract platform-tools.rar using WinRAR.
- Put the downloaded update zip file in the platform-tools folder.
- Now go to the platform tools folder and press Shift button and right click your mouse or touchpad. Click on “open command window here” from the list of options.
- After the command window appears, type “adb devices” command and press enter and see if your Nexus device is shown. If it is visible, it will show a device id under the list of devices attached.
- Type the command “adb reboot recovery” and press enter.
- This will get your phone rebooted and you need to choose recovery mode.
- This will take you to a screen with a sleeping Android logo with red exclamation on top of it.
- Disconnect your phone from the computer or any kind of charger and press the power button for about 3 seconds and press the volume up button. This is a bit tricky part so, you need to keep trying if you don’t get it the first time.
- Now after reaching the stock recovery screen, with volume down, highlight “apply update from ADB” and press power button to choose it.
- Type this command “adb sideload <update file in zip format>” and press enter. If you have done everything right, you will see the computer transferring the update to your Nexus device.
- Once the transfer is done, your device would start verifying and installing the upgrade.
- When it is complete, choose “reboot system now” and you are ready to taste your Kitkat.
This is something I have done myself, so this is a tested and safest way of getting your official upgrade without waiting endlessly for the OTA.
