[SOLVED]Flashing kernel for Miui 2.2.1, always getting "turn on Unknown Sources..."

Hey guys.

I'd like to flash my X10 Kernel with the ftf given with the Miui 2.2.1 rom. But the thing is, when I open flashtool, after doing all the steps and when I connect my phone to the computer, here is what I get :

17/007/2012 18:07:46 - INFO - Start Flashing
17/007/2012 18:07:46 - INFO - VER="R8A013";DATE="20100119";TIME="17:24:00";
17/007/2012 18:07:46 - INFO - Flashing loader
17/007/2012 18:07:46 - ERROR - Error flashing. Aborted
17/007/2012 18:07:46 - INFO - Now unplug the device and power it on
17/007/2012 18:07:46 - INFO - Then go to application settings
17/007/2012 18:07:46 - INFO - turn on Unknown Sources and Debugging

It is always turned on, both of them, so I went in, I turned them both off, then again one of them on, then the other one on, then again both on, nothing happens, it's always the same error message.

Somebody can help me please ?

Thanks !

Btw, I am on Miui 2.3.2 Cobrato
With baseband 2.1.71 & Kernel 2.6.29-zdzihu-mod4.05
And I have both CWM and xRecovery.

Thanks, I'll try it now !

EDIT : PC Companion tells me that there is an update (3.0.1.G..., the official 2.3.3 from Sony). If I do this update, will I have to install again xRecovery, CWM, root it, unlock bootloader, etc etc ?

So I tried with the charger's USB cable, it doesn't seem to change anything ...

Well, I'll downgrade it and try to start from the beginning.

Thank you

EDIT : Yeah it's done !

I made the update that SEMC wanted me to do, because I didn't know on which generic I should downgrade ^^'. So I did it, then I rooted it, unlocked bootloader, installed CWM, and installed the app from CWM

Thank you for your help !
