Earlier this week, Google began rolling out an update to their Nexus and Google Play Edition lineups. It was Android 4.4.3, which fixed a ton of stuff. We now have the OTA for the 3G version of the Nexus 7 2012. So those of you that bought that version of the original Nexus 7 can now update to Android 4.4.3. This update will take the Nexus 7 from build KOT49H to KTU84L. Now before you sideload this update, you’ll want to be sure that you have build KOT49H already on there. We’ve got the download link at the bottom of this post for those interested in sideloading the update.
In order to sideload the update you’ll need to have the Android SDK installed, and have your bootloader unlocked. Next you’ll need to make sure it’s connected to your computer and ADB is working. you can do this in a command prompt window by typing “adb devices” and you should see a “device” with a serial number next to it. If not, you may need to switch to PTP from MTP or vice versa. Next you’ll want to type “adb reboot bootloader” once it’s rebooted, go ahead ahead and type “adb sideload <filename here>.zip” once it’s done sideloading the update it should reboot and voila. You’re all done. It’s just that easy to sideload the update. It works the same way on all Nexus devices for any Android update as well.
