How to root Sony Ericsson Xperia Mini Pro with linux computer

I have found a lot instructions, but most (or all) of them use a Windows GUI application to root the device. The Linux scripts, that I found did not work. My telephone: * Model: Xperia Mini Pro (SK17i) * Android-Version: 4.0.4 * Kernel-Version: 2.6.32.9-perf * Build-Nummer: 4.1.B.0.587 How can I root this phone with a linux computer? **HINT** This is not a duplicate question, because I want to do it from Linux (not Windows) and second the [alleged solution](https://android.stackexchange.com/questions/1184/how-do-i-root-my-android-device) does not contain an answer for my phone!
