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.
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.
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.
- Charge the Nexus 7 to at least 80%
- Make sure the drivers are installed before flashing (see following steps)
- Save data
Flashing Android 4.3 on the Nexus 7 via Fastboot
- Download the correct firmware for your model, make no mistakes here!
- Unzip the contents of the firmware in a folder named for example ''AndroidNexus7''.
- Download Fastboot + ADB drivers and unzip the contents to the same folder in Windows.
- Put your Nexus 7 in Fastboot mode, to do this turn it off and press the volume up button, volume down and power simultaneously.
- Connect your Nexus 7 in Fastboot mode to your PC via USB.
- <<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.>>
- In ''AndroidNexus7'' folder, launch ''flash-all''.
- 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.
