Install Android 4.3 on the 2012 Nexus 7: walkthrough and video

Google introduced the new Nexus 7 last week, which will run on the new version of the operating system: Android 4.3. While the OTA update should be available on older Nexus devices, if this does not happen or you just can't wait, here's how to do it manually.

Simple Method

First of all, try the method given in this tutorial in the forum: Install Android 4.3 on the Nexus 7, simple method. If it does not work, you can flash the offcial Google firmware as explained below.

Disclaimer

Flashing a ROM, even an official one, involves risk. If you do not follow the procedure properly, you can end up with an unusable device. Neither AndroidPIT or myself will be held responsible for anything bad that comes your way, so proceed at your own risk.

Be warned: this method results in the loss of all your data, so back up all your data first.

Prerequisites

  • Charge the Nexus 7 to at least 80%

Flashing Android 4.3 on the Nexus 7 via Fastboot

  1. Download the correct firmware for your model, make no mistakes here!
  2. Unzip the contents of the firmware in a folder named for example ''AndroidNexus7''.
  3. Download Fastboot + ADB drivers and unzip the contents to the same folder in Windows.
  4. Put your Nexus 7 in Fastboot mode, to do this turn it off and press the volume up button, volume down and power simultaneously.
  5. Connect your Nexus 7 in Fastboot mode to your PC via USB.
  6. <<If you haven't unlocked your bootloader already, press Shift key and right-click in the fastboot folder, then select ''Open Command Prompt.'' Once the Command Prompt is open, enter the command ''fastboot oem unlock'' and exit Command Prompt. Your tablet will ask if you want to unlock, select ''Yes'' and let it do its thing.>>
  7. In ''AndroidNexus7'' folder, launch ''flash-all''.
  8. A window will open, from this moment, leave your PC alone. Do not disconnect your tablet. You may feel that the system is blocked, but this is not the case. Some phases are long, so just don't touch anything and wait till the process is complete. If you have any questions or issues you can join the forum discussion for this tutorial here.

The New Android 4.3 Walkthrough

Ok, so now you're all set up with Android 4.3 Jelly Bean on your 2012 Nexus 7. What's new? Not much, mostly performance enhancements and a couple nifty features we can't show you, like Bluetooth Smart v4.0 for connecting to low-power Bluetooth devices, Open GL ES3.0 accelerated graphics as standard for enhanced gaming and real-time image rendering.

As for what we can show you, there's the main feature of Android 4.3 which is of course, the multi-user feature with restricted profile options. Check out the video below for a quick walkthrough of the new-look OS and there's some screenshots too to demonstrate the new features if video is not your thing.

Multi-User Restricted Profiles

First of all you can see the lock screen is different for each user. You have the multi-user buttons at the bottom of the screen, and depending on what settings have been put in place the interaction is entirely different. For example, in our 'owner' profile, you have the screen-lock PIN pattern, in the other profiles you simply swipe to unlock.

If you're in 'owner' mode, you can add new users and set different options for the restrictions that will apply to their profile. There's everything from access to Chrome and Google Earth, to File Managers and the Photo Gallery, and you can limit access to Google services like Hangouts, the Play Store and Wallet. You simply flick on/off switches for the restrictions you want to activate.

Once you've made the restrictions, the tablet responds differently depending on which user is in control. For example, you can see the limited app options in the restricted profile compared to the owner profile. The background and other preferences are all different too. However, we did note you can't change language options between users, something that would be handy in our multi-lingual office.

There's also some changes to the Daydream screensaver and the Notifications pull-down tab. / © AndroidPIT

Have you installed the new Android 4.3 update on your Nexus 7? What do you think of the minor changes to the operating system?

    tested the restricted user tonight, found a big flaw, anything downloaded from Amazon Market opens and complains that you must have uninstalled the Amazon market. And then you click OK the close the app.

    testing more as I'm hoping I can use it to safely provide games.

    That's an interesting flaw John. Can you just clarify for me though: do you mean that anything downloaded previously from Amazon Market won't open in the restricted profiles?

    hi Kris, yes, when you have restricted access to the Amazon Store, I have been unable to open apps from that store. I receive an error telling me that the store is not available and I should reinstall it

    Hi John, I asked a developer here about your apps being linked somehow to the app centre they came from and he said the following:
    ''You have two kinds of update notifications. You can write code in your own app to check your own server for updates and let the user know that there are updates and redirect him to a store. Or... The app store that the user has, usually has a background process running that checks for updates and notifies the user.
    If an app doesn't work anymore because it loses access to the app store it came from it's probably because there is code in the app to make it dependent on it in order to run. Which is strange, but I've never used the Amazon store...''
    Unfortunately neither have I, but it might be worth contacting the Amazon customer support to get some more answers to this problem.

    Do you mean the ''fastboot oem unlock'' command? Is your bootloader locked? Are you in fastboot mode? The system above worked fine for us. Just double check you're in fastboot mode (press the volume up button, volume down and power at the same time) and then connect and try the fastboot command again.

    Ah yes! You ALWAYS have to back up first! Glad your lesson didn't cause you any major loss of data.

    Thank you so much for making this! I accidentally deleted the OS from my Nexus and I was distraught and thought I had bricked this. But with this guide I easily reinstalled the OS and now my tablet works again! I cannot thank you enough!
