How to flash Android 4.4.3 KTU49L for 2013 Verizon Nexus 7 LTE with ADB Sideload:

This first guide works with Stock Recovery.

Remember that this guide can be used only by overwriting the stock Android 4.4.2_r2 KVT49L build with the new Update zip file.

  1. Download the Razorg KTU84L from KVT49L for N7 LTE tablet from here.
    – note that the name of the downloaded file is long and it would be best for you to rename it to ‘update.zip’.
  2. After you rename the file you should move it to your computer’s SDK> ‘platform-tools’ folder.
  3. Switch off the 2013 Nexus 7 LTE tablet now.
  4. Next, boot it in Recovery Mode.
  5. After the Recovery Mode is loaded you should select ‘apply update from adb’.
  6. Use the USB Data Cable and connect it to your computer.
  7. Open the folder where you’ve moved the ‘update.zip’ file.
  8. Now, press and hold ‘SHIFT’ key and, at the same time, right-click on the folder’s white-space and select ‘open command window here’.
  9. Windows command window will launch now and you should enter ‘fastboot devices’ and see if your tablet has been detected by your computer.
    – if the Nexus 7 LTE 2013 device isn’t detected, then you will have to re-install its USB Drivers.
  10. Now you can install the new Android 4.4.3 OTA Update zip file. Enter this command line: adb sideload update.zip
    – if you didn’t change the update zip name, then you will have to enter the complete filename for the installation to begin.
  11. Your tablet will start the updating process, wait until the installation is complete without pressing any buttons.
    – also, do not unplug the tablet from computer during install process.
    – the update will take somewhere around ten minutes.
  12. When the installation is complete you will see the main Stock Recovery menu again. Select ‘reboot system now’.

That is it, these were all the steps that you had to take in order to update your device to the latest Android 4.4.3 KTU84L firmware.

Wait for the tablet to reboot successfully in normal mode and then unplug it from your computer.

If your device has a custom Recovery installed on it, then you can choose to install the new update using the second tutorial below.

Flash Android 4.4.3 KTU84L Update zip for Nexus 7 2013 LTE from Custom Recovery Mode:

This post will work with both CWM and TWRP Recovery images.

Note that your tablet’s OS shouldn’t have been edited in any way beside of the installation of a custom Recovery. If you’ve applied any ROM modification, then the tablet will not boot in normal mode after installation and you’ll be forced to flash a ‘factory image‘ in order to repair the device.

  1. Download the Update zip file from here.
  2. Move the file to your Nexus 7 LTE 2013 model.
  3. Power off the tablet.
  4. Now you should boot in Recovery Mode.
  5. Select ‘install zip from sdcard’ for CWM and ‘Install’ for TWRP.
  6. Find the Android 4.4.3 KTU84L zip file and confirm installation.
  7. When the update is complete you should reboot the tablet in normal mode.

I hope that you’ve managed to complete the installation for your tablet. In case you need more help you should ask for help in comments.
