As usual, when a device is first released, the biggest worry around here is whether the device will get rooted. In some cases, the root method can be ridiculous. In other cases the root method can be pretty simple. In all cases, root being achieved is a positive thing and that’s even if it’s an overly complex method. Sony Xperia Ion users are fortunate, however, as their root method is relatively simple.
XDA Forum Member yuunanase has released a method that’ll get the LT28i rooted pretty quickly and without much effort. Users are first instructed to unlock their bootloaders. From there, they are to download an insecure kernel to flash. After that, it’s a matter of running a quick root package script and downloading the Superuser and Busybox Installer apps from Google Play. That’s all there really is to it.
Although the root method has been reported working, there are a few users who may be uneasy about flashing an insecure kernel. For these users, there may be another solution in the works, as yuunanase may be working on a pre-rooted system.img with the help of XDA Senior Member Spectre51 for users to flash instead of the kernel. So if the kernel method is not for you, there may be a second option coming soon.
