How to Root the Sony Xperia Mini Pro

The Mini Pro was one of the successful phones from the Xperia lineup of smartphones by Sony. One of the big features the phone offered back when it was released was a QWERTY keypad for those of us who still preferred to text using the actual physical buttons rather than tapping the screen.

In addition to the keyboard, it had pretty decent specs when it was released and plenty of features to get you through your daily tasks. But, it can still be further improved, and even made to run on the latest versions of Android (that it will never receive from Sony themselves) by rooting it. There are plenty of root-required apps that let you further customize your phone and help you take it to the next level and even a custom recovery should you want to flash an entirely new version of Android on the device.

Rooting the Sony Xperia Mini Pro isn’t a daunting task; all you need to do is use a tool to flash a root-able kernel and then root the device. Once that’s done, get back to the stock kernel and you’re all set. Here’s how we do it:

Before You Begin

  1. This could void the warranty of your device. We won’t be held responsible for anything that happens from doing this tutorial so please proceed at your own risk.
  2. You must have a Windows based PC to do this procedure as the tool that you’re going to use is Windows only.
  3. You should have ADB USB drivers installed on your PC. Install them if they aren’t already.
  4. Your device must be running on Stock ICS firmware 4.1.B.0.431. If yours doesn’t run this, you shouldn’t follow this procedure.
  5. This procedure only works for the SK17i variant of the device. You must not do this procedure on any other variant or device.

    Hello David, I am trying your howto with my SK17i. I know it’s the end of 2017 already :), but I was able to gather all the downloads you mentioned. The stock firmware version matches, I have installed the required flashmode drivers under Windows 10 and I am using the same version of Flashtool as you did and yet the phone ends up in an endless boot loop when it is on the Neo V kernel. The hardware “back” button keeps lighting ON and OFF in a loop and the phone never fully boots. Did you see such behavior? https://uploads.disquscdn.com/images/9a06eb4bab2e6abf11566ebba0c27fc3af2289efbf780a268fe128ee60cdbc29.jpg
