Hey All - Version 2.0 of the custom kernel for the Samsung Replenish is now formally RELEASED. A zip file is attached to this post. Please read this entire post before installing this updated kernel to make sure your phone meets the criteria to run this kernel.
1. Over-clocking now enabled. For those of you using my app CruseControl, or who have an app like SetCPU installed, you will now see that there are an additional 6 frequencies with a max CPU speed of 787 mhz (the stock kernel only goes up to 600 mhz). As an idea of what this does for us, I have installed netflix from the android market and can actually view the content now with almost no jitter. For those of you who have tried this before, it was impossible to use netflix as the video and voice were completely out of synch. It is not almost perfect!
2. I tweaked the SmartassV2 kernel to provide better battery life. This is currently my governor of choice.
As with all kernel releases, use at your own risk. I always use my kernels before I release them, and have been using this version 2.0 for some time with no issues found. Note that some believe over-clocking for long periods of time can burn out a CPU. To prevent you from unknowingly usnig higher than stock supported CPU frequencies, I have set up this kernel to max out at 600 mhz (the stock max speed) UNLESS you specifically select higher CPU frequencies through CruseControl or some other CPU controlling app.
2. Two additional CPU governors:
- The interactive governor
- The SmartassV2 governor.
A CPU governor "governs" the frequency of the CPU. The better ones strike a balance between speed and conservation of battery life. I have been running with the SmartassV2 governor and have noticed an increase in battery life as that governor will move the CPU frequency (speed) to its lowest allowed speed when the screen is off. Just google smartassV2 or interactive governor for details on what these governors do.
And for anyone who is going to install this new kernel, your phone must:
1. Be running Phoenix ROM 0.2 or higher.
2. You must have ClockWorkMod recovery installed as the update.zip I will provide needs that to install properly.
I STRONGLY recommend you back up your phone through clockworkmod BEFORE you install the kernel. I have been running it for almost 2 weeks, and have used the update.zip to install it, however I am not responsible for any damage to your phone should you have issues with the install. If you have a backup, it will be easy to get back to the stock kernel.
2. Reboot to ClockWorkMod recovery mode (hold down the "U" key as you power up our phone)
3. Backup your phone if you have not already!
4. Once the backup is complete, select option "install ZIP from SDCard"
5. Select sub-option "apply /sdcard/update.zip"
6. Select the Yes option.
7. Reboot when complete.
The install takes just a few seconds. It will be obvious as you reboot if it worked or not as the splash screen at boot changes.
Let me know via this forum of successes (or failures which should not occur if you followed these instructions and you phone meets the install criteria outlined above).
Version 2.0 Release Notes:
This kernel contains all of the goodies release in version 1.0 with the addition of:1. Over-clocking now enabled. For those of you using my app CruseControl, or who have an app like SetCPU installed, you will now see that there are an additional 6 frequencies with a max CPU speed of 787 mhz (the stock kernel only goes up to 600 mhz). As an idea of what this does for us, I have installed netflix from the android market and can actually view the content now with almost no jitter.

Version 1.0 Release Notes:
1. EXT4 support build into the kernel. This kernel is made specifically for Firehak's Phoenix ROM which switches our phones from the RFS file system to the EXT4 file system (this increases speed). This kernel does not support the old RFS file system currently. As such, ONLY install if you are running phoenix ROM 0.2 (or above).2. Two additional CPU governors:
- The interactive governor
- The SmartassV2 governor.

Installation Instructions
1. Download the attached update_v2.zip file, rename if update.zip, and place it in the root directory of your SDCard.2. Reboot to ClockWorkMod recovery mode (hold down the "U" key as you power up our phone)
3. Backup your phone if you have not already!
4. Once the backup is complete, select option "install ZIP from SDCard"
5. Select sub-option "apply /sdcard/update.zip"
