How to Root Xperia Neo L MT25i

Xperia Neo L has a very small developer community so, unless you can build your own ROMs, there are very limited things you could do with your Xperia Neo L. But you can still gain root access on your device very easily. Don’t know what “root ” is? Read about it here.

Before proceeding, you must know that following this procedure may render your phone inoperable (bricked state). This happens in very rarely. The forum will not be responsible for any damage caused to your device.

• Make sure your device is at least 70% charged to avoid complications during the process.

• Backup all of your important stuff like contacts, messages etc. You will loose all of it during the process. For backing up the phone, refer to this post.
