Rooting Xperia Mini 4.1.B.0.587 - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

I just updated my phone from 2.3.4 to 4.1.B.0.587 , It was written on SONY website that it is 4.1.B.0.587 but as I check it in my Settings section it is written 4.0.4 , However as I read many topics this number thing is nothing unorthodox! It is actually 4.0.4 but the build is 4.1.B.0.587 or whatever ;D
Anyway again as I read many topics on this forum it is needed to have the kernel file for 4.1.B.0.587 to be able to ROOT the device.
I checked this link : talk.sonymobile.com/thread/41119
There's no Kernel file for my device... (I do NOT want to install another ROM)
Is there any way to ROOT my device ?

Wrong forum, this is xperia ray's forum.

Wrong section. Post your question on Xperia Mini,Mini Pro,Active General section.
For root your mobile first you need to download flashtool then flash back to 4.0.3 using flashtool then root your phone & flash again to 4.0.4(.587)
It is not possible to root directly from .587

And don't worry about 4.1.B.0.587 because u just update your phone from 2.3.4(Gingerbread) to 4.0.4(Ice Cream Sandwich) & 4.1.B.0.587 is your current ROM version.
I am also on 4.1.B.0.587 & it is the latest update from Sony.

If you want to unlock your bootloader, it's easy enough to root whatever android version or build number your phone has; hotboot cwm recovery image as kernel and then install superuser using cwm.
btw, what baseband version do you have now?

In flashtool select 4.1.B.0.587 ftf. (there is no only kernel ftf, select the downloaded one)
Select (mark) exclude Fota, system and baseband, (dont thick the kernel on flash tool)...
Select 'No final verification'
DE-SELECT wipe data, cache and apps log.
(Just flash the kernel not the entire rom)
Click OK and follow instructions (power off phone, press volume down button and plug the usb).
This way you can flash .587 kernel back.

OP doesn't ask how to get original kernel back as he didn't flash any custom kernel yet.
And by assuming OP wants to unlock the bootloader, it's simplier and easier to hotboot (not to flash) cwm recovery image or any compatible kernel that has cwm to use the cwm to install superuser.

Is it the best way to do it ? Are there any topics about it on the forum so I can read and test it ? Because I see many people are still messing around with Xperia Minis and have no succeeded yet to root their phone ;

I'm pretty new to the Android universe so I do not all the special terms yet so forgive me for saying that I do not know what is "Unlocking the Bootloader" exactly. I'd be glad to read a topic on this website about it if there's any to know what it is and what are the advantages/disadvantages.
Baseband Version :8x55A-AAABQOAZM-203028G-72
Android Version : 4.0.4
Build Number : 4.1.B.0.431 (???????!!!!!!!!!!)
Kernel Version : 2.6.32.9-perf
Why is the build number .431 ?!!!! I was sure it is .587, Even I checked it last night. Is it because I was messing around with Flashboot ? Can flashboot change the buildnumber ?!!

Xperia Mini does not get build ICS 562
Xperia mini instantly got ICS 4.0.4 build 431, and Latest update Build 587, so I think flash kernel of Xperia ray or other Xperia to Xperia Mini it could not be done for rooting your phone
I recommended your phone Unlock Bootloader

Your build number is .431 from the first you updated it, see your baseband version: 72, build .587 has baseband version 77.
build .587 isn't available for Xperia mini yet.

Follow this guide.At step four, "IV. Flash 4.0.4 ROM: "- Flash the build 587 firmware. You'll get it here : http://talk.sonymobile.com/thread/35239?start=0&tstart=0 All other stuffs are same.You can root by unlocking bootloader and flashing 562 kernel also : http://talk.sonymobile.com/thread/41119?start=0&tstart=0 But it's a little bit risky because if you unlock your bootloader officially,you will lose your DRM keys and track id will never work again..
