What did you use to rename the files es file explorer won't work for me "might be coz of noobness" and terminal emulator keeps coming up segmentation fault can I use ADB maybee ? Any other easy way I am missing?

I used Root Explorer to rename the files... but still haven't gotten an answer to if I renamed them correctly. :(

I simply ran flash.bat. I'll try this approach.

Edit: nevermind, both files are _dis. Changing them to _ins now.

Edit 2: after following your instructions, the CPU did in fact go to the Max oc setting. On the negative side, "everything is laggy and benchmark scores are cut by 50+%. When I disable CPU Master, or SetCPU, the clock drops back to 1512Mhz and everything is buttery smooth. Makes no sense to me.

Is the intellidemand governor enabled by default, or do you have to enable it with a third party app? If the later is true, then I think it may be the cause of the performance hit.

It is on by default. If you don't like intellidemand to manage, simply switch back to ondemand if you want.

The locations for the files is /system/bin

if using adb:
Code: 
adb remount
adb shell mv /system/bin/mpdecision /system/bin/mpdecision_dis
adb shell mv /system/bin/thermald /system/bin/thermald_dis

OKay finally got a chance to try it and success but phone was noticeably and i mean massively laggier and no wifi?????
No idea what I am doing wrong, followed instructions step for step,
was i suposed to rename _ins or _dis,
tried both no win there :(

I was wondering if it was me or is there just no voltage adjustment available via setcpu?

I would love to undervolt so my battery doesn't crap out on me in like a handful of hours with it set at 1.5 GHz

Seconded; I don't like this System Tuner app too much.

Once the implementation for the voltage tables is added for SetCPU, it opens a vast array of tools (read: Xan's Voltage Control, etc).

No, not really.

sweep unlock is gimmicky in nature, and causes additional battery drains due to sensor needing to be active in order to detect finger movements (regardless of wakelock or irq based). Also when pocket your phone with that feature enabled, all sort of funny things would happen.

Just flashed 004 kernel, can't turn on my wifi.... help

on WCX AT&T ICS 3.6

Here's the full instruction:

Instructions:

1.Rename your thermald/mpdesicion from /system/bin folder to thermald_dis/mpdesicion_dis
2.Extract boot image from the provided zip.
3.Plug your phone to pc then open cmd, navigate to your /android/sdk/tools
4.then adb reboot bootloader
5.now run "fastboot flash boot boot.img"
6.hit recovery on bootloader menu
7.Extract the bcmdhd.ko from the provided zip to your desktop
8. go back to your open cmd inside /android/sdk/tools.
9.Run 'adb push /users/youruser/Desktop/bcmdhd.ko /system/lib/modules
10.Now adb reboot

you need to install the module again.. some reason your module didn't install right.. blame HTC for S-on making flashing kernel such a pain.

with ADB do:
Code: 
adb remount
adb push /your/folder/bcmdhd.ko /system/lib/modules
adb reboot
Done!

Flash.bat worked

Those having trouble with Flash.bat try this worked for me
ensure you have ticked install from unknown sources in /setings/security
with these changes the install script worked after a week of frustration with it.
Could be coincidence but i am thinking not.

Unless faux123 changed something in the latest version?

EDIT: I was wrong it ran and didnt bootloop but also didnt install the kernel???
Can a mod delete this maybe?

Ok, got it to work! I had to manually mount system in recovery (not by adb but manually within recovery) and then push the module to system lib

Everything working smoothly!

Went back to doing this manually after reinstalling ADB and finally it worked, had no wifi and had to manually push bcmdhd.ko and away it went
And as lehoi79 said you will have to manually mount system via recovery to be able to do any steps which involve /system.

Initially my phone didnt like 1.7GHz at all getting much better results at 1.56Ghz will try dropping some voltage but definitly got some improvements pretty pleased, hoping to gain some battery life with single core with screen off as well

So... How much undervolting are you guys able to do and keep it stable.... I've read in other kernel threads that -100 is normally pretty stable... But I wanna ask before I screw my phone up

I think it will vary alot depending on luck and quality of cpu etc.
Also dont forget will be different used outside when hot compared to inside in aircon etc.
dropping it one click at a time in system settings an waiting to see if stable for a bit then quadrant etc. rinse repeat

    NOTICE: This is COMPATIBLE with ALL Vivid Rooted Stock and Custom ROMs

    For frequency control use fauxclock from Google Play

    Just a statement regarding kernel source: The Kernel Source is of course covered under GPL version 2. Free software does NOT mean no work or time was spent working on it. I have donated a large sum of my free time to hack this kernel. If you use my modified kernel source in parts or in its entirety, I kindly ask you mention its origins and to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source. Thank you :cool:

    ​


    Hi XDA members and fellow Vivid users:

    This is my tenth kernel hack. I want to thank Erasmux, and several others I cannot recall for inspiring me to venture into this unfamiliar territory for me.

    What is a Kernel? The Kernel is the Foundation in which everything else builds upon in any software system.
    [Car Analogy]: Kernel is like the Engine, Electrical system and the Transmission to a car. The Library, Framework and the Apps [AKA ROM] are the body frame and the rest of the Car.


    ​


    THIS KERNEL is BASED ON HTC Source Code. So it is COMPATIBLE ONLY WITH HTC ICS Vivid Builds.

    Please DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibilities (Forced Close).

    CleanCache (via ZCache backend)

    ZCACHE is a new technology I introduced to HTC Kernel. ZCACHE is a compressed cache similar to ZRAM but the similarity ends there. ZCache is meant to provide as many "cleancache" pages (non-dirty or untouched "virgin" memory) to apps that request for new memory. CleanCache is very easy to allocate and no additional penalty are required to hand them out, so having more CleanCache pages will improve performance. Under heavy memory pressure, often times the kernel will NOT have enough CleanCache pages, so the kernel has to do EXTRA work to reclaim dirty cache pages and clean them for the new apps that's requesting for them. The described process creates a performance hit for the kernel and the app, so the idea is to use compression to create more CleanCache pages available for use. Of course there's a penalty to pay for using compression, but the trade-off between compression penalty and the penalty for reclaiming dirty cache pages and allocating them after cleaning is smaller for compression, so in the end, CleanCache should add more performance.

    ZRAM (aka CompCache aka RAMZSwap)

    ZRAM is an updated version formally known as CompCache and RAMZSwap. It was originally designed for 2.6.38.xx kernels, I have backported to our 2.6.35.xx kernel. ZRAM allows real-time compression of memory objects in RAM thus reducing memory pressure for the Linux kernel and can keep more apps in memory longer (more apps in RAM == better performance, less fetching from slower MMC or SDCard). Compression, however, is not Free. Some CPU cycles are required to do the compress/decompression, so there's a slight penalty for it. The original CompCache / RAMZSwap required a user space binary to control its behavior which adds additional penalty to performance, but the new version ZRAM eliminated the need for a separate dedicated daemon, thus reducing the overhead and increased performance from the old CompCache by 20%. Therefore, with the newer implementation of ZRAM interface, the performance penalty is almost negligible. :D

    Joe's RCU (Optimized for Small SMP systems)

    Joe Korty has created an RCU for small SMP systems (> 32 cores). His approach is to isolate all the Garbage Collection (GC, a slow time consuming but necessary processing) to a single core, thus allowing other cores to ONLY work on real required processing. This will allow the additional cores to complete their assigned tasks as fast as possible (not bogged down by GC) then immediately go back to a suspended state (saving battery).

    Fast No Hz RCU (Optimized for SMP operations)

    Fast NoHz is an optimized version of the traditional Tree RCU. Many new kernels are using the Tickless NoHz design. This RCU is tailored and designed to work with the new NoHz kernel system.

    SmartAssV2 Governor (Balanced)

    This governor has a built-in "profile" similar to SetCPU, so screen off will use lower clock rate thus conserve more battery, but it also has a fast wake up feature so that user interaction will not see the lag when switching from Sleep to Wake state.... (So SetCPU Profiles are sorta redundant when using this governor, you can still use SetCPU to OC to higher than default Clock frequency).

    Interactive Governor (Performance)

    This governor is designed to put more priority to User Interface (UI aka Apps) tasks, therefore appears more responsive then the traditional OnDemand governor. So if you want the smoothest UI interaction, this governor is for you...

    Brain F*ck Scheduler - (BFS)

    This scheduler is designed to be simple and speedy tailor specifically for user interface type systems such as desktop/smart phone devices where user interaction is MORE important than serving 1 million web requests (CFS, the default scheduler) at the same time (think of nimble desktop workstations vs large corporate servers).

    SLQB - (SLAB allocator with Queue)

    This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate). Not all kernels are using SLQB including CM7 main line...

    Fair Budget Queue (BFQ I/O scheduler)

    This I/O scheduler is an improvement on top of Completely Fair Queue (CFQ). CFQ is fair in terms of time but not in terms of throughput / bandwidth, so BFQ make sure that both time and throughput / bandwidth are balanced across all requests.

    Low Voltage - Under Volt the processor, therefore uses Less Battery, but NOT ALL CHIPS can handle Under Volt.. If you experience instability, try the Stock Voltage Version.

    Stock Voltage - Uses the voltage values from ORIGINAL HTC Kernel Source.

    There are NO PERFORMANCE DIFFERENCE between the Under Volted and Stock Voltage versions!

    Installation Instructions:

    Here's a step by step instruction to install this kernel:

    1. download the above file (via phone directly or to a PC)
    2. copy the downloaded zip file to /sdcard/download/
    3. Open ROM Manager and select "Reboot into Recovery" and select "OK"
    4. Once in recovery, select "wipe cache partition", select "Yes", then select "advanced", then select "Wipe Dalvik Cache", then select "Yes" again. Once finished, click the back button to go back to the main recovery menu. On that menu, select "Install Zip From SDCad", then select "Choose zip from SDCard", then go to /sdcard/download and select the downloaded zip file and let it run its script.
    5. Once the script is done, select "reboot system now"

    Note: After FLASHING, the first reboot may take longer than usual, please be patient... After the first reboot, it may lag during initial load (let everything finish loading). Once everything is loaded and phone is ready for use, reboot the phone a 2nd time and the lag will be gone and everything should be silky smooth...

    NEWS BULLETIN:

    Ice Cream Sandwich Version 007 is out. More intelligent intellidemand! Completely free yourselves from mpdecision, thermald and now with intellidemand, complete CPU/Thermal Management by the kernel.


    Please don't hesitate to talk among yourselves and help each other out... The XDA community is what inspired me to hack kernels for everyone since everyone here is nice and helpful to each other... Keep helping each other.... Famous proverb: It's better to give than to receive...

    You shouldn't be flashing via cwm. I've included a script for pc tethered flashing. Just run flash.bat on pc with USB cable connected to the phone. You may need to run it twice if it failed to load the modules.
