[Q] Help to root - Sony Ericsson XPERIA X10 Mini

I'm new to the Android world and I wonder how do I root the x10 mini E10a that my brother gave me.
From what I've been reading, I must be very careful not to make the root on a wrong firmware version, so I would like your help, if possible, create a step-by-step.
And that is my phone information:
Model number: E10a
Firmware version: 2.1-update1
Baseband version: M76XX-TSNCJOLYM-53404006
Kernel version: 2.6.29 [email protected] #1
Build number: 2.0.A.0.504

Rooted with z4root. :good:

A quick guide:
1. Go to 'settings-apps' on your phone.
2. Check the option 'unknown sources'.
3. Go to 'settings-apps-development' and check the option 'USB-Debugging'
4.Download and install the software from this link (for windows):
http://forum.xda-developers.com/showthread.php?t=2122682
5. Connect your turned on phone to your computer (if its the first time you connected your phone, a popup like 'installing new driver software' could appear, wait till it says 'successfully installed')
6. Open the software you installed.
7. Click 'Root' in the newly opened window.
8. Wait for the process to finish.
9. Done! Your phone is rooted!

Now I'm trying to install a ROM, but the requiriments are:
Root and CWM Recovery already installed
Latest 2.1.1.A.0.6 SE firmware due to kernel dependencies.
My firmware version is 2.0.A.0.504 so I tried it below:
Force-update to 2.1.1.A.0.6
Grab this build.prop file and copy it to your sdcard
Using Root explorer, backup your /system/build.prop file and copy the grabbed build.prop file to /system/build.prop
Reboot twice and try to re-update your firware. You might need to force-update if SEUS or PC-Companion says you already have the latest firware.
Once the update completes, check again your firmware version.
Unfortunately, after I did it above, still can't update the firmware. Tried with SEUS and PC-Companion and both says that I already have the latest version and gave me no option to force update.
What can I do now?

Just install newest software via Seus, even if it says you have newest software (NOTE: I'm not absolutely sure if this works, only whenever I reflashed via Seus, I always had newest firmware on my phone).

Yes that's right . You just need to install via SEUS even if it says that you already have latest version bla bla bla it doesn't matter just install anyway. The rest is just root phone and instal cwm ( for me i used unlockroot to root the phone, it never fails ), then just flash the kernel you want by flashtool and you're ready to go, the rest is just flash your roms and stuff xD.
