[T-Mobile myTouch 4G Slide] Blue6IX:
Team doubleshot kernel project.​

Unfortunately the developer is unable to post source for these kernels at this time. Because of this, I am closing this thread and removing the download links. If you have any questions about GPL compliance, feel free to read this post.​

Updates listed here:

-Added new version of 1.5 kernel in post 3.

-Added 1.7 kernel in post 3.

-Added CPU frequency table list in post 5.

Note:

A kernel takes at

least

a solid 24 hours to finish building caches and get itself fully installed and humming.

Even that depends upon usage to a degree, so make sure that you give your kernel ample time to settle in before you start to evaluate it's performance.

Custom kernel management:

Installing custom kernels:

[1] - Download the kernel zip file to your sdcard.

[2] - Flash through clockworkmod recovery just like a ROM.

- If you do not know how to do this, you should learn how to flash ROMs before moving on to kernels.

SetCPU

- SetCPU is an app that lets you regulate the clock speed of your device. ( and more! )

- Check out the app in the XDA News page, and then check out the Dev thread.

- Consider donating and buying the market app to support the developer if you really use the app.

Custom kernel information:

WARNING:

Flashing a kernel meant for 1.28.539.9 or 1.28.539.10 software on 1.55.531.3 software will most likely result in boot loops. The boot.img files are structured differently.

Make sure you are flashing the right kernel for your software version or ROM.​

Undervolt kernels

Post 02 - Undervolt kernels

The post on undervolt kernels will contain kernels focused on the battery savings that undervolt can bring. Some undervolt kernels may be overclocked.

Undervolt kernels will send less power to your CPU and save you battery power.

In extreme cases this can cause brownouts or maybe not being able to recover from sleep mode - but no actual damage to the device can result from undervolting.

Significant battery savings can be gained through undervolting depending on usage and implementation.​

WARNING:

Installing an Overclock kernel on your device could have negative physical consequences (Read: broken hardware) if misused/abused.

Please educate yourself on what overclocking does and how you can melt your processor.

You proceed at your own risk and any damage that may result is the sole responsibility of the end user.​

Overclock kernels

Post 03 - Overclock kernels

The post on overclock kernels will be focused on pushing the limits of the clock speed for the device. Some overclock kernels may be undervolted.

Qualcomm, the manufacturer of the Snapdragon chip in the device rates them at 1.5GHz. Here is a Snapdragon Product Overview that may help you track down more information about the Series 3 Snapdragon processor in the doubleshot.

In extreme cases overclocking can melt your processor. Direct physical damage can result from increasing the CPU or GPU clock speeds above manufacturers recommended speeds.

Anyone intending to use an overclock kernel should first familiarize themselves with the device hardware and implement such things at their own risk.​
