HowTo: install xRecovery in Xperia X10 Mini Pro

Update: I got ClockworkMod Recovery working on my phone, that’s a better choice.

xRecovery is a custom Android recovery system for all variants of the Sony Ericsson Xperia X10, including Xperia X10 Mini Pro. If you want to take it to the next level by being able to take and restore full backups, flash custom ROMs, manage partitions and wipe not just data but cache and Dalvik cache as well, you have to install it.

It’s similar to ClockworkMod Recovery which cannot be installed on SE devices.

Here the steps I used to install xRecovery on a Xperia X10 Mini Pro.


  1. check your handset details via “Settings” – “About phone”
    • Your “Baseband version” must be M76XX-TSNCJOLYM-53404015
    • Your “Build number” must be 2.1.1.A.0.6
  2. check if you have root access (you can use Root check app)
  3. you need Android Terminal Emulator app (install from the Market or apk download here)
If you need to root the phone you can follow my guide.
If you need busybox you can install it with Busybox installer
Software requirements

Unrar the archive and from your pc type:

$ adb push AAIS/ /sdcard/

Use install.sh via Android Terminal Emulator (root user):

$ su
# cd /sdcard/AAIS
# sh install.sh

Choose 0 or simply push “Return”
At the end (3-10 seconds) phone will reboot.

All done.
A good idea: make a backup
Enter recovery:

  1. power off phone
  2. when booting your phone and when the “Sony Ericsson” letters appear, press and release continuously the “back” button
  3. once you are in the CW recovery, use the volume keys to navigate upwards / downwards, the “home” or “camera” button key to select, the “back” key to go back
  4. choose “Backup and restore” – “Backup”
  5. reboot

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.


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
#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.


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:

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

Step by step guide

  1. Start putting device in “debug mode”: Settings – Applications – Development – USB debugging
  2. 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.
  3. 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
  4. 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)
  5. 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
  6. 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.
  7. 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)
  8. 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
  9. It’s time to reboot:
    # reboot

That’s it.


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.
