Trying to unlock bootloader on x10 mini pro - Sony Ericsson XPERIA X10 Mini

Hi chaps,
After trying a gingerbread rom and finding it too slow, I see most other roms require a custom kernel for best performance (and being able to use most other roms!)
Anyway, I'm running through the tutorials in the stickied Guide in this forum and during the unlocking the bootloader instructions it keeps telling me to switch my phone off.
Now it doesn't mention having the phone plugged into the PC at any point in that section but I assume you have to for the SE Tweaker tool to work .
My problem is that in the first couple of steps I'm told to turn my phone off yet as it's connected to the PC, it keeps switching back on to charge ie. it's not staying off.
So naturally me being afraid of bricking my phone and it being a first time for me, I haven't progressed past this part. Any help or guidance would be much appreciated.
Thanks

Turn your phone off and leave it disconnected from your PC
When the unlock procedure asks you to plug in your phone, press the back-button while you connect the usb-cable to your phone.
This way you enter flash-mode, which is what the tools require.

I can't seem to enter flash mode :/
I hold the back button and connect the phone to the pc. Initially it installed some flash driver onto the pc and then booted up as normal.
Now it just boots up as normal no matter how long I hold the back button (throughout the whole process so far)
Does having xrecovery have anything to do with this?
Thanks
Edit - my antivirus was quarantining s1tool.exe! derp.
Edit 2 - Success! Thanks chaps. You're all pretty cool in my books

Help
Hi,
i don't know if this comes under this section also,
i lost the post that i was using to update my x10 mini pro from 2.1 to 2.3 after my pc freezed and restarted.
So my SE finished the update but it's stuck on the Sony Ericsson text on boot up in faint brightness.
I used flshtool 0.9.0.0
rooted the phone and installed busy box.
restarted the phone with the blue screen menu a selected the NAa kernel from SD to load.
After that rebooted the phone then sony ericsson text came very bright then it starts to faint to minimum and nothing else happens.
If i connect flashtool i will get the following:
02/046/2012 14:46:55 - INFO - Device disconnected
02/047/2012 14:47:16 - INFO - Device connected with USB debugging off
02/047/2012 14:47:16 - INFO - For 2011 devices line, be sure you are not in MTP mode
02/047/2012 14:47:24 - INFO - Device disconnected
02/047/2012 14:47:26 - INFO - Device connected with USB debugging on
02/047/2012 14:47:27 - INFO - Connected device : U20
02/047/2012 14:47:27 - INFO - Installed version of busybox : BusyBox v1.19.4-cm7 bionic (2012-02-04 22:27 +0100) multi-call binary.
02/047/2012 14:47:27 - INFO - Android version : 2.3.7 / kernel version : 2.6.29
i even tried SEUS but nothing happens it would ask to reboot in flashmode and the device will enter flashmode and nothing happens.
also tried to restart with the blue screen menu by pressing power and the back button multiple times and back with volume + and - nothing occurs.
I downloaded ver 0.9.1.0
and tried the force root and here is the log:
Any solution ?
Thanks in advance.

You have to flash the kernel from flashtool:
Put the kernel zipfile in the /firmwares folder where you installed flashtool
Choose the flash-button
Choose the kernel
Connect your phone in flashmode and it will be done (if your bootloader is unlocked)
You can not install a kernel from the sd-card using the CWM (blue screen) menu
The reason your phone doesn't boot up is because your ROM and Stock kernel are not compatible
If you're succesful in flashing the kernel, you should be fine.
There is no need to root your phone before you flash the kernel, and the ROM is pre-rooted.

In your original post you said you tried to install the kernel from sd-card using the CWM menu, which is impossible
I suppose you have to unlock the bootloader first, in flashtool it's under the plugins-section.
But you first have to make sure it is safe or you can brick your device doing that
Go find the post where you got the kernel from, it will have a link to the bootloader unlock tutorial.
Use that to get instructions on how to know if your device is safe to unlock.
Then use the bootloader-unlock in flashtool's plugin-menu to unlock the bootloader.
Then flash the kernel.

Yes i did the root and unlocked the bootloader.
and loaded the kernel from SD card using CWM menu.
It was asking to load the kernel from SD card,
i wish i could boot with CWM to give you the exact steps.
The device was i guess able to work but i read somewhere in forum to try rooting again using force psneuter
and that was when things changed on the device cause i used to see in Clean Root icon in flashtool lot of apps and commands in red now only ls: in red is there!!
Regards

You can NOT flash the kernel from the sd-card
Only from your PC, and your phone does not need to be rooted for that, you only need an unlocked bootloader.

Try to do a repair with SEUS or PC Companion
Then flash the kernel
Boot into the CWM menu (included in the custom kernel)
Then flash the ROM you want

hmm, weird, normally the only problem there is that SEUS says there's no firmware available Keep pressing the back-button till it actually starts flashing.
