NOTe this requires you to have a NExus 7 20013 Wifo (flo) device that is at Android 4.3 (JSS15R). If you need to check download the Android App
Nexus Update Checker”.
I hope this helps any Android newbies get KitKat installed a bit early. Unfortunately there is so many posts with bad or missing info that I figured I should do it up right.
- First thing you need to do is make sure that your device is in developer mod. To do this go into “About device” in Settings and tap on the “Build number” entry seven times, which will unlock “Developer Options”.
- Now that Developer Options are enable you will need to turn on “USB Debugging. To do so go into settings – “Developer Options” – Toggle on “USB Debugging”
- You will need to download Android SDK. It is a ZIP file. Extract them to C:\users\%username%\SDK. Make That folder should contain 2 folders and SDK Manager.exe
- Run SDK Manager. If it doesn’t run it most likely you don’t have JAVA installed. There should most likely be a USB driver update. Install/Update Package
Install the Android Driver
Plug in your Android Device. You will need to open up Device Manager. Go to: Control Panel -> System -> Device Manager
You will see something like this:
Right click it and install driver. Point it to the folder: C:\Users\Jared\SDK\sdk\extras\google\usb_driver. The driver will install.
Make sure ADB see’s the Nexus 7 as well. In the platform-tool directory run the command “adb devices”. Let this window open.
Great almost Done!
The Nexus 7 2013 OTA (Over the Air) update needs to be downloaded. This is the same file that google would “eventually” let us all download. Save it as KitKat.zip and put it in C:\Users\%username%\SDK\sdk\platform-tools folder
Turn off the Nexus and turn it on by holding down Power and Volume Down buttons at the same time.
Connect your device to your computer using your Micro USB cable.
Get into “Recovery Mode” by hitting the Volume Down button. Use Power button to confirm.
Your device will reboot and you should now be seeing an Android logo with a red exclamation mark. Hit power and then quickly hit Volume Up button.
Select “Apply Update from ADB”
Because you left the command prompt open you have to now type: “adb sideload KitKat.zip” without the quotation marks.
Now if you you get the error: “Error: device not found” while installing KitKat it means you have to install one more driver.
Go to: Control Panel -> System -> Device Manager
You will see something similar again:
Right Click “Galaxy Nexus” and select “update driver software…”
On the next screen click this button:
On the Next screen say “Let me pick from a list…”
On the next screen select “show all devices”
Say Have disk and point Windows to: C:\Users\Jared\SDK\sdk\extras\google\usb_driver
A Windows will pop up asking what you want to install. Select “Android Bootloader Interface”.
Go back to the command prompt and type: adb sideload KitKat.zip
After updating there is already several updates. Check for updates and let them apply right away. Also make sure all your app get updated as well.
