HowTo: root your Xperia x10 mini pro 2.1.1.A.0.6 – 2.1-update1

In this post I’m going to show you how I manually achieved root on this device.

Preamble

I tried every possible automated tool I found (z4root, SuperOneClick), but I had no luck.
My setup involves a GNU/Linux box and this may be the cause.
First of all here are the device details I got from “CurveFish DeviceInfo” app:
Model: U20i Manufacturer: Sony Ericsson Device: U20i Product: U20i_1238-0129 Brand: SEMC CPI ABI: armeabi Kernel Version: 2.6.29 SEMCUser@SEMCHost ) #1 PREEMPT Fri Dec 17 18:35:45 2010 Build Number: 2.1.1.A.0.6 Release: 2.1-update1 SDK: 7
Full log here Xperia X10 Mini Pro.deviceinfo.txt.

Prerequisites

Here’s the required tools:

a PC (mine is powered by Ubuntu 11.04 Natty Narwhal)
an usb cable for your mobile
adb configured and running on the PC (find more info here)

Software used:

psneuter
source code here: https://sites.google.com/site/root4android/rooting/psneuter-c
compiled binary can be found inside SuperOneClick
direct download link: psneuter
su
source code here: https://github.com/ChainsDD/su-binary
compiled binary can be found inside SuperOneClick: search for su-v2
direct download link: su-v2
Superuser
source code here: https://github.com/ChainsDD/Superuser
compiled binary can be found in the Android market page
direct download link: Superuser_2.3.6.1.apk

Once you have all the necessary stuff, we can start!

Step by step guide

Start putting device in “debug mode”: Settings – Applications – Development – USB debugging
Connect device to pc using usb cable and start adb with
adb shell
You may to choose “Charge phone”, so you can still access your sdcard within the phone.
Check you can write in this specific directory:
$ cd /sqlite_stmt_journals $ touch testfile $ ls -l -rw-rw-rw- shell shell 0 2011-08-02 16:23 testfile $ rm testfile $ ls -l $ exit
If everything went ok, put the needed files in the previous directory; from your pc terminal type:
$ adb push psneuter /sqlite_stmt_journals 3157 KB/s (585731 bytes in 0.181s) $ adb push su-v2 /sqlite_stmt_journals/su 630 KB/s (26264 bytes in 0.040s) $ adb push Superuser_2.3.6.1.apk /sqlite_stmt_journals 3533 KB/s (196521 bytes in 0.054s)
Prepare the software on the phone:
$ adb shell $ cd /sqlite_stmt_journals $ ls -l -rw-rw-rw- shell shell 196521 2011-08-03 13:16 Superuser_2.3.6.1.apk -rw-rw-rw- shell shell 26264 2011-08-03 13:16 su -rw-rw-rw- shell shell 585731 2011-08-03 13:15 psneuter $ chmod 755 psneuter
Now you can exec psneuter. You will lose the active shell.
You could see this message or not, that’s not a problem:$ ./psneuter property service neutered. killing adbd. (should restart in a second or two)
Your phone will detach and reattach usb connection automatically.
Once more you have to connect to the device with adb shell, but you’ll see a different prompt:$ adb shell # id uid=0(root) gid=0(root)
Now we have a temporary access to root user via adb.
Let’s do the trick on the system:
# mount -o remount,rw /dev/block/mtdblock0 /system # mkdir /system/xbin # chmod 755 /system/xbin # cat /sqlite_stmt_journals/su > /system/xbin/su # chmod 6755 /system/xbin/su # ls -l /system/xbin/su -rwsr-sr-x root root 26264 2011-08-02 18:19 su # cat /sqlite_stmt_journals/Superuser_2.3.6.1.apk > /system/app/Superuser_2.3.6.1.apk # chmod 777 /system/app/Superuser_2.3.6.1.apk
It’s time to reboot:
# reboot

That’s it.

Verify

One easy way to verify the process is to install “Android Terminal Emulator” from market and type:
$ su #

if you get the Superuser popup and the right prompt “#” it’s all ok.
