Please make the Overclocking kernel like other devices have means we can chose the clock frequency. I hope so we can be able to attain upto 1.4 ghz...

Boot loop

Hi everybody!
I would like to try this kernel, but I have a boot loop...
I'm running a stock rom with 6.1.1.B.1.54 firmware + CWM and my XU is rooted...
I have just flashed the .zip in recovery... Did I make some mistakes?

Thanks and sorry for my english =/

If you can afford to read few previous replies, you'll come to know that this kernel is only for Gingerbread and not for ICS (6.1.1B.1.54).

That is why the bootloop occurs.

Ohh thank you! But it's not in the description...
Do you know if there are some custom or tweaked kernels for ICS?

This kernel seems great, it's so bad there is no ICS version =(

For ICS too there are great kernel's out there.

U can try Vengeance Kernel / Munjeni's kernel / The Brains kernel / Sliding_XU.

Just search for the respective kernel inside Xperia U Development section and u'll find it.

PS: Am not advertising but my personal fav. is Vengeance Kernel because it supports lots of governors and I/O schedulers + has Overclock ability till 1150MHz. Though it is not much but it is really great.

    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 ==

    == 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!

    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 :)

    == Xperia SSpeed kernel v2 ==
    - 1.2 GHz
    - Changed frequency's from 600Mhz, 800Mhz, 1Ghz to 700Mhz, 950Mhz, 1.2Ghz
    - Added governors: Interactive, Smartass, Minmax, Smartassv2
