I present to you
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

== Signature image ==

thank you just two question before try this one.
1) If download fails, i have to reapply the entire rom kav02? It's possible to have a link with original kernel?
2) this kernel reduce the duration of battery?

thanks in advice

I just made the kernel :) I know it works because I tested it :D I don't know about the battery life. And I'll provide the stock kernel in second post :)

Only flash? Nothing more?

Yes :)

v2 coming up :)

- New governers: Interactive, Smartass, SmartassV2, minmax => these are not tested on stability yet but they won't brick your device or something worse :p
- Oc to 1.2GHz probably :)

Hy all
I'm using the kernel v2 and it's very stable, but there is lag using smartass/smartassv2/conservative/interactive governors while all ok using the ondemand governor. Can you also optimize the use of ram in future versione , xperia u suffers for the lack of available RAM.
Congratulation for the kernel and the rom :)

The new governers aren't fully optimized yet for our new device ;) So that's why they can cause lag. I'm going to test v3 tonight when my mom is home and I can have her Xperia U :p

Thanks so much for all the work ... you are going very fast with development. Your rom is extremely fluid with this kernel, no bugs to me.

Lol I'm in my exams so I'm not at full speed at the moment :p

But I know everything is going good at the moment :)

    Reserved for downloads or maybe something else in the future ;)

    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 ;)
