Backup and Other Important Tips

Done with the USB drivers? Perfect. The tutorial is on the next page, but first, please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps:

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. See below for some tips on how to backup data:

If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your tablet, we strongly recommend you to also backup using that as it creates a complete image of your existing tablet set up.

A few more optional tips that you should remember:

1. Having problems connecting your Android tablet to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and Jelly Bean.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your tablet goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your tablet might get bricked or go dead permanently. No one wants that, right?

4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your tablet is locked to a carrier, unless we have specified the carrier name or device model.
