As promised, Sony began rolling out ICS for their 2011 Xperia line recently, and will continue to do so until nearly everyone gets some ICS goodness. That said, some devices are getting it sooner than others, and among those that are getting it now are the Sony Xperia Neo and Neo V. Coming along for the ride will be the challenge of rooting the new firmware—both for previously-rooted users to retain root and for those acquiring superuser privileges for the first time. Thankfully though, this challenge was accepted, and completed, and is now ready for users.
XDA Senior Member Madfysh has released a tutorial to safely guide users through the root process under a variety of situations. The root method requires users to know the basics of fastboot and ADB, and you need working fastboot access in order to install. Luckily for new users, however, Madfysh has listed the commands you’ll need. The guide also comes in different methods depending on whether or not your bootloader is unlocked. Essentially, there is a guide for you regardless of which configuration you’re coming from.
