- Fully working

THIS KERNEL HAS MMC_CAP_ERASE REMOVED AND IS FULLY SAFE FOR ALL WIPES ON ALL ROM TYPES​

Kernel Installation

Install either through CWM or PC/Mobile ODIN in the usual manner. Wiping Cache and Dalvik Cache is unnecessary and wont make any difference. Flash only with 25% or more charge on the phone

Installation routine for the rom of your choice

- Either flash HydraCore or have a kernel installed with CWM

- Download your ROM of choice, follow any specific rom installation instructions (in the ROM thread OP) and flash with CWM

- Flash HydraCore in CWM or with Mobile / PC Odin

Kernel Versions

There are two versions of this kernel, one with native OC/UV and one with standard (stock) frequencies. If you are new to this kernel, flash the STD (standard) version first, as this will work with all phones.

As you become more experienced, you might want to try the OC/UV kernel, which sets the maximum CPU speed to 1600Mhz and Maximum GPU speed to 400mhz. The OC/UV kernel is undervolted, and in some circumstances can offer significant performance improvements. However, it *may* use more battery and you phone will get a little warmer.

CPU Frequencys and how they are used

Not all apps/games force the CPU to ramp up to the highest frequency (1.4 or 1.6 GHz, depending on the kernel variant you flashed). For example, while playing Temple Run, Coin Dozer and Mutant Roadkill, the CPU will mostly stay at 600 / 800 MHz. Even while playing intensive games like Pocket Legends, the CPU will stay at 600 / 800 MHz most of the time, with the CPU ramping all the way up to the maximum frequency only when very intensive graphics occur, which is like 20% of the time.

Known Issues

- Button Backlights in TouchWiz ROMS

Setting the "Touch key light duration" to "Always Off / Always On" will not behave as such. The touch keys will light up and stay like that for up to three seconds if touched directly. Touching / unlocking the screen will not cause them to light up. On non-TouchWiz ROMs, this behavior has not been detected.

REPORTING BUGS

When reporting a bug, please provide the following information

- The ROM you are using

- The kernel version (oc / std)

- Your phones voltage group (settings > about > kernel information)

Failing to provide this information will result in your post most likely being ignored - remember we cannot help you if you cannot provide us with information we need

Other information, history and for German speakers

You can find the complete history of this kernel, with all older changelogs and news, all translated into German by our friend Atonal at this link. You will also find a complete download set of all versions of my kernels at the same place! brilliant :)

Kernel Kitchen, Full Source code and GPL:

Basically i can't be bothered with GitHub so I make my entire build directory, build scripts and initramfs available in one complete package. This is compliant with the GPL licence.

You can unpack the package to any folder anywhere on your system. You will need a cross compiler toolchain installed, and set the Makefile in source/Makefile point to the cross compiler location. Codesourcery's arm-none-linux-gnueabi 2012/03 release is recommended.

Read the README-INSTRUCTIONS file, and from a root terminal, run the menu.sh script. The rest is obvious :good:

The source packages contain the following

- Kernel kitchen

- Unmodified reference source

- Modified files directory

- Working source directory

- a .patch which you can use to patch any other sources with (includes ALL changes)

- Initramfs

Kernel kitchen source package FTP directory and downloads -

DISCLAIMER

By flashing any custom kernel you understand the risks involved. As with any flash, there is always a small risk that something could go wrong and/or data loss. I am in no way responsible for any damages, loss of data, brickage, loss of work or any other loss associated with any faults due to the installation of this software.
