It's a soft brick, don't worry :), you can't put gb kernel on ics rom.
Since you should be able to enter recovery, just wipe everything and flash some of the gb roms through it and you should be able to boot. If that doesn't work flash stock ftf via flash tool, that has to work :)

Devs are currently working on it. For a little speed boost you can choose to flash from two custom ics roms around here. Or if you prefer to remain on stock rom you can delete unnecessary apps from /data/app and /system/app with root explorer. You have to be rooted of course.

If you are on ICS just flash an ICS kernel with recovery via fastboot. This is a GB kernel!!

thanks. i have managed to fastboot different kernels to my device, but i had wiped out all data and deleted a rom by mistake.
and now i have other problem. my xperia won't stay in flash mode longer than 30 seconds.
i am runing windows 7
why is that so ?
i have tryed to reinstall flashtool drivers and change the usb port, but as soon it disconnects from flash mode it starts booting kernel.

    KA Xperia SSpeed kernel v6
    31/07: Xperia SSpeed kernel v6.1 released & changelog updated on 3rd post
    Please hit the thx button if you like my kernel :D

    Dear Xperia U users,

    This kernel is based on .564 stock sources. I'll continue to add more features to the kernel in the future

    I hope you enjoy my kernel :D

    == features ==
    - Pre-rooted
    - recovery
    - Added things for better performance
    - Small changes for battery life
    - Extra governers: Pegasusq

    == download == Xperia SSpeed kernel v6.1 ==
    - XDA Fileserver: KA Xperia SSpeed kernel XDA Fileserver

    - mediafire: Xperia SSpeed kernel v6

    == download == Stock kernel ==
    - mediafire: Stock kernel Xperia U

    I kindly ask everyone not to mirror my download links. Thank you

    == Important information ==
    - The extra governors aren't optimized for our new Xperia 2012 devices yet. So lag or reboots can occur
    - The extra I/O schedulars are also not edited for Xperia 2012 devices so they can also cause lag.
    - Overclocking is a risk, be aware it can harm your device if you do things wrong. But dont worry, 1.15Ghz won't harm your device :)

    == credits ==
    - Nick Holtus/ICX & atarii for helping me build my first kernels
    - KeiranFTW for the recovery
    - Doomlord for his work on Xperia 2012 kernels
    - Sony for kernel sources
    - And everyone who helped nick and Doomlord ;)

    == Installation instructions ==
    Important! Only for unlocked bootloader
    1) Go to recovery
    2) install zip from sdcard => choose my kernel zip file

    I am not responsible for damage to your device, use at own risk!

    == Future Updates & changelog ==
    - Check third post ;)

    == kernel sources ==
    - sources: github

    == Known Bugs ==
    - Report them and I will try to fix them as soon as possible

    Can I ask a question?WHy are you releasing new kernel 100Mhz more at a a time?

    For safety reasons, we haven't been able to add VDD (voltage control) yet so it's not safe to go higher then 1.2GHz at the moment. Maybe 1150 is even better. The Xperia U, P and Sola are devices with st-ericsson CPU (Novathor 8500) and it's very difficult to make OC at the moment..

    The only thing we can do is change the stock frequency's, we haven't been able to add freq's yet... As soon as we found out how to add new frequency's we will start searching for VDD and better OC ;)

    V2 is released :)

    - Changed frequency's from 600Mhz, 800Mhz, 1Ghz to 700Mhz, 950Mhz, 1.2Ghz
