How to Unroot the LG Optimus Zone
Maybe you’ve run into issues on your LG Optimus Zone? Maybe you want to send in your device for warranty reasons? Either way, this guide should help you. It teaches how you can unroot your LG Optimus Zone smartphone and get it back to stock. Here you go:
Unrooting is the process of removing root access, a custom recovery (if you have one), and just trying to get the device back to as close to stock as possible.
Some of the reasons for unrooting your LG Optimus Zone are:
- Sending in the device for warranty (most, but not all unrooting procedures reinstate the manufacturer warranty if you had one before rooting).
- Starting over (simply undoing everything you did while rooted so you can have a clean slate to start over).
- Fix any issues (Maybe rooting messed something up? No problem, unrooting will take care of it for you).
