[Sony Ericsson Xperia Neo, Pro] S9Papa:
Hi, I bad speak english. But i'll try

I did this:

1.Start Flashtool.

2.Connect the phone with the computer via USB cable.

3.Wait till flashtool shows that your device is recognized. You will see your phone model on "Connected device:"

(Since MT25i is not yet listed on flashtool devices list, you can choose MT11,

it will still recognize your phone and will show your current firmware on " Connected Device")

4.Disconnect your phone from your computer and turn it OFF.

Now we are going to set Flashtool to flash the Neo V Kernel on your device.

If you have downloaded Neo V Kernel & Neo L Kernel, go to flashtool installation directory and paste it on FIRMWARES folder.

for me its installed on C:\Flashtool\Firmwares\ (paste both Neo V Kernel & Neo L .FTF file here)

1.Open Flashtool.

2.Click on LIGHTNING ICON and Mode Selector window will appear.

3.Select Flashmode and click OK, Firmware Selector window will appear.

4.We need to flash NEO V Kernel first, so select MT11i from the left pane, and KERNEL.SIN from the right pane and hit OK.

5.Animation window will appear showing how to connect your phone.

6.Press and Hold Back Button (dont release yet) and plug you USB cable into your computer.

(BLUE LED WILL LIGHT UP WHEN YOU SUCCESFULLY CONNECTED ON FLASHMODE)

7.Flashtool will start searching and you can only release PRESSING & HOLDING BACK BUTTON when the tool recognize your device and start flashing.

but, my result:
