How to Unroot the Sony Xperia L

Perhaps you’re done playing with root and custom ROMs on your Android device? Regardless of the reason, it’s usually pretty easy to unroot your device and go back to the stock firmware.

Some of the reasons for unrooting your Sony Xperia L 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).
