It is possible that your tablet might become unresponsive or starts miss-behaving. Or perhaps you’ve forgotton your unlock code and can’t get back into your Nexus 7. As a last resort you can always perform a ‘factory reset’ to put the tablet back into its initial state.
Note: This will erase all stored content from your tablet and uninstall all apps and saved content.
Always backup your data regularly, you never know when you will need to rely on a backup. Backup early, and backup often. Remember that content stored in the “cloud” can easily be downloaded to your tablet again after the reset. This is where services such as Drop Box come in very useful.
If you can still get into your tablet and Android is still operational, then the following steps will be the way to go:
- Open up Settings > Backup & reset
- Select Factory data reset
- Select Reset tablet
- You will need to enter your Pattern, PIN, or Password if your tablet is protected
- Press “Erase everything” to confirm
Nexus 7 Hard Reset
If you can’t gain access to carry out the above steps then you can still perform a reset via the Nexus 7 recovery mode, you can perform a “hard” reset by following these steps:
- If your tablet is on, switch it off.
- Press and hold Volume Up + Volume Down + Power until your Nexus 7 turns on. If all has gone to plan you’ll see an Android lying on its back!
- Press Volume Down twice, until the screen says “Recovery mode.”
- Press Power to restart into “Recovery mode.” You’ll see an image of an Android with a Red triangle appear after a minute or two.
- While holding down Power, tap Volume Up
- Use the volume keys to scroll to “wipe data/factory reset” and press Power
- Scroll down to “Yes – erase all user data” and press Power to select
