Upon positive feedback to my initial post and several requests in the modded-cm7-thread, here's the thread for the development section.
This thread is about providing everyone with my CyanogenMod 7 Kang and the modifications I added to it. Both ROM and Kernel are compiled from source in a Linux environment. Note: This is by no means my ROM. My work is based on the awesome efforts by everyone who contributed to CM7. While initially I built the ROM only for myself in order to adjust a few things to my liking, after some development I thought "It's so good, I might as well share it".
Highlights of my CM7 Kang:
All CM7 commits up to September 25, 2012
Very smooth and snappy overall experience (smooth spinners, smooth indeterminate progress bar, different screen transition animations, some other things)
Enhanced audio experience (digital audio mixer, increased headphone volume, Beats Audio, more volume increments)
Increased battery life through kernel tweaks like writeback variables, underclocking, WLAN undervolting, and LED-button light dimming
Custom CM7 Kernel with battery-optimized smartass2 governor, additional interactivex and ondemandx governors, default SIO i/o scheduler (2012 version), battery optimized sysctl variables and many more improvements
G-key usable as a launch button for the camera app, as shutter key inside the camera app, and also as music play/pause key when the screen is locked
increased camera jpeg quality (pictures are ~ 1.3 - 1.7 MB)
Option to center the statusbar clock (not enabled by default) and change the clock's color (white by default)
Option to set the statusbar color (not enabled by default). You can choose between fully transparent, semi-transparent, and any custom color.
Optional 1.2 GHz overclocking via menu
Fixed GPS performance, largely fixed audio routing and fixed call quality
VPN support
Customizable installation with Aroma installer
G-recovery

Notes:
Installation: to install, go into CWM and select the package via 'Install zip from sdcard'. Upon this, a graphical user interface will guide you through the setup process.
This package contains everything that was previously listed under 'download links': ROM, Kernel, Google apps, Beats Audio remover, localized GPS fixes, WLAN failsafe Kernel, the format script, additional applications, and the option to remove some stock applications.
The Aroma installer gives you the possibility to customize your installation: you can freely choose any component you want to install without the need to install anything else. For example, you could only install the ROM, only the Kernel, only a GPS fix, etc.
There is no need to do any wipes in CWM - the installer will take care of this.
Besides the fully customized installation, there are two quick install options available in the installer: 'Install CM7' and 'Update CM7'. Those will perform the necessary wipes and install the bare CM7 ROM (including Google apps) for you. No other additional apps will be installed or removed.
When installing the CM7 ROM, the European GPS fix and Beats Audio are already included by default.

- All CM7 commits up to September 9, 2012
- Replaced (the optionally installable) Root Browser with ES File Explorer since it has better functionality
- Updated (the optionally installable) AlarmDroid app to the latest version
[B]cm-7-package-20120905-p970-boype[/B]
- Reverted RIL to v11b due to occasional loss of signal problems
- Reverted camera libs to v11b due to the first two seconds of video recording being black
- Set touchscreen refresh rate slightly above the display refresh rate for smoother scrolling (71 Hz)

- Updated Play Store and ROM Manager to latest version
- All CM7 commits up to September 5, 2012
- Kernel: Reverted CPU transition latency to 15ms (LG default)
- Compiled Kernel and ROM with default CM7 toolchain (GCC 4.4.3) for maximum compatibility and as few bugs as possible. Linaro caused strange behavior sometimes!?
[B]cm-7-package-20120826-p970-boype[/B]
- Updated all LG proprietary files to V20N (GPS, graphics, RIL, sensors, video codecs, ...). The files prior were still from V11B (Froyo).
- Re-compiled package with Linaro toolchain, since random errors were reported
[B]cm-7-package-20120824-p970-boype[/B]
- Set audio capture mixer to 'Digital' (was 'Analog' before)
- Increased microphone sampling rate for voice calls to 16 KHz (was 8 KHz before)

- Boosted speaker volume a little
- Added option to choose transition effects from within aroma installer: the current LG Froyo effects are set as default, but the CM7 default ICS-effects can be installed as well.
- Fixed bug in aroma installer where Europe GPS fix could not be (re-)installed
- Fixed bug in aroma installer where Play Store disappeared and could not be recovered after updating the ROM / re-installing Google apps

[B]cm-7-package-20120817-boype[/B]
- Fixed GPS not working when screen is off
- All CM7 commits up to August 17, 2012
- Added AROMA installer for an "all in one" package (thanks to tantrums for the help). All previously available flash files (ROM, Kernel, GPS fixes, apps, ...) can be installed from AROMA. You don't even need to do wipes in CWM anymore, as a formating script is included.
- Updated some outdated applications (Google Search, Play Store, Superuser)
- Kernel: added USB battery drain fix
[B]cm-7-20120809-p970-boype[/B]
- Another attempt to fix the 'overamped' microphone during handset calls (I'm not talking about the background noise issue here)
- Fixed front camera not working in high quality video mode
- Fixed GPS fix not setting permissions properly on first boot
- All CM7 commits up to August 9, 2012
- Kernel: Fixed the issue where the CPU ramped down (or only appeared to ramp down!?) way below 200 MHz
[B]cm-7-20120805-p970-boype[/B]
- Reverted microphone gain on handset calls back to standard values, while maintainig the increased gain for everything else. (Some users reported distorted sound due to high gain. Actually, I assumed that calls were excluded from the gain.)
- Went back to standard app package - no apps removed, no apps added (not even google apps). Can't argue with personal taste...
- Pre-set GPS fix is set to European NTP server (so no need to flash the EU GPS fix)
[B]cm-7-20120803-p970-boype[/B]
- All CM7 commits up to August 3, 2012
- Fixed GPS permission issue being repsonsible for bad GPS fix performance
- Fixed large parts of the (very messed up) audio routing:
- In a call, when enabling handfree (speaker) mode, the interlocutor could not hear anything
- In a call with headphones attached, the interlocutor could not hear anything
- In a call via headset, the interlocutor experienced very low volume
- Increased overall mic recording volume by 66% (Regular calls are excluded from that. However, e.g. Skype calls and voice recording are boosted.)
- Added option to set the statusbar color (not enabled by default). You can choose between fully transparent, semi-transparent, and any custom color. (By JerryScript. [URL="https://github.com/thekraven/android_packages_apps_CMParts/commit/7e5f2170e85d24ecd749eebcf409377d0020ea55"]source 1[/URL] + [URL="https://github.com/thekraven/android_frameworks_base/commit/7479afb07eaa5b0a1445d439904284bba9649ebd"]source 2[/URL])
- Fixed a small bug with the center clock, which wasn't correctly "rolled in" after events in the status bar ticker.
- Changed Launcher to the official Play Store version of ADW Launcher (gives a little better performance and smoothness)
- Integrated Google apps (gapps) into ROM package and updated most of them to the latest version
- Integrated the LG Memo app and widget (pulled them from a stock GB ROM)
- Integrated Root Browser, Fancywidgets (great weather widgets), HTC IME mod (superb keyboard) and some other useful apps
- Deleted useless apps from ROM: DeskClock, FileManager, LatimIME, LiveWallpapers, LiveWallpapersPicker, MagicSmokeWallpapers, Protips, RomManager. I have added a zip package with the deleted apps to the OP, in case you want any of those apps back.
- Integrated a couple of notification/ringtone sounds: 'Guitar 2' and 'Major' from HTC, 'Wake up' from Sony Ericsson, and two retro Super Mario sounds :)
- Kernel: Set CPU OPs to 200-400-600-800-1000-(1200) MHz
- Kernel: Re-integrated almost all parts of LG DVFS and rewrote them to work with the new frequencies. This largely stabilizes the kernel!
- Kernel: Tweaked voltages, GPU frequencies and screen-off ramping behavior to optimize battery life
- Kernel: Fixed WiFi hang on re-enable. Connecting WiFi is really fast now :) (Thanks to Conn O'Griofa). ([URL="http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=patch;h=04dd4dc82b0960ff95c3adc58c07da3ce699a67f"]source[/URL])
- Kernel: Undervolted WLAN some more
- Kernel: Added ondemandx governor and changed to regular smartass2 / interactivex governors (non-DoomLord versions)
- Kernel: Updated SIO to 2012 version and tweaked it slightly
- Kernel: ...more changes under the hood. Check the sources if you're interested.
- Updated building environment: Kernel and ROM are compiled with Linaro toolchain 11.10 / Java JDK 6u33
[B]cm-7.2.0-p970-20120715-boype[/B]
- All commits up to July 15, 2012
- Implemented Beats Audio into the ROM for an enhanced music experience. If you don't like it for some reason, just use the Beats Audio remover listed under the download links. Huge thanks to RockoDev. ([URL="http://forum.xda-developers.com/showthread.php?t=1525226"]source[/URL])
- Kernel: fixed the SOD / freeze issues. Thanks again to kdo_vi and Siguiriya for beta testing.
- Kernel: fixed the issue where the phone was laggy for a minute or so after changing the frequency. This means, that you can now also set your desired frequency and governor on boot without any initial lag or other downsides.
- Kernel: removed a lot of LG DVFS stuff from the code. Only the very necessary lines for a smooth operation remain.
- Kernel: lowered LED-button energy input by ~40%. Battery savings 'hello' ;)
- Kernel: tweaked SIO a bit for better I/O performance
- Kernel: some more changes under the hood. Check the Kernel source if you're interested.
- A sidenote for the benchmark kids: Change your governor to ondemand or interactiveX when you want to get the best possible synthetic benchmark scores.
[B]cm-7.2.0-p970-20120711-boype[/B]
- Kernel: Fixed bug where CPU frequencies and governor could not be set properly in CM Settings -> Performance -> CPU Settings (I removed parts of LG DVFS for that)
- Kernel: increased voltage for 200 MHz CPU frequency to get rid of reported SODs
- Kernel: added optional 1.2 GHz overclocking support, selectable from the CM Settings -> Performance -> CPU Settings menu
- Kernel: added SIO i/o scheduler and set default
- Kernel: smartassV2 is default governor again
[B]cm-7.2.0-p970-20120710-boype[/B]
- All CM7 commits up to build date
- Kernel: Underclocked the lowest CPU operating point (OPP) to 200 MHz (was 300 MHz before) and applied lower voltage for that OPP. Also adjusted GPU frequencies in a linear way for all OPPs (each 100 MHz increase adds 80 MHz more GPU clock, so in the end the default GPU maximum of 800 MHz is reached at a CPU speed of 1000 MHz). [B]Huge thanks to Huexxx and his [URL="https://github.com/Huexxx/diana/commits/v2"]released Kernel sources[/URL]![/B]
- Kernel: lowered WLAN voltage to save battery. Operating voltage is now between 1.7 Volt and 2.7 Volt (was 1.8 - 3.0 Volt before).
- Kernel: Set tickrate to 72 Hz. I expect this to be a battery saver when screen is on.
- Kernel: Back to deadline i/o scheduler
- Kernel: More kernel stuff under the hood, see the Kernel source if you're interested
[B]cm-7.2.0-p970-20120704-KANG[/B]
- All CM7 commits up to build date
- G-key is no longer a "dead" key:
- when screen is on, long press will open the camera app
- inside the camera/camcorder app, g-key will serve as camera shutter key (Enable it in camera app -> advanced settings; I implemented this function)
- When the screen is off, long press can be set to toggle music play/pause (Enable it in Settings -> CM settings -> Input; I unlocked this function)
- Increasing ringtone option (cherry-pick, authored by Danny Baumann; [URL="http://review.cyanogenmod.com/#/c/18401/"]source 1[/URL] + [URL="http://review.cyanogenmod.com/#/c/18402/"]source 2[/URL] + [URL="http://review.cyanogenmod.com/#/c/18403/"]source 3[/URL])
- Disabled trackball options from Settings -> CM settings -> Input (since the optimus black has no trackball)
- Added 40mb heapsize to Settings -> CM settings -> Performance settings and set as default (was 32mb before)
- Kernel: added interactivex and set as default governor
- Kernel: set noop as default i/o scheduler
- Kernel: added support for VPN (compiled and integrated tun.ko module for that)
- Kernel: added g-recovery by sergey1369. When you have a bootloop, you can still access CWM by repeatedly pressing the G-key while booting. Also thanks to Huexxx for answering a question ;) ([URL="http://code.google.com/p/g-recovery/"]source[/URL])
[B]cm-7.2.0-p970-20120625-KANG[/B]
- All CM7 commits up to build date
- Added "center clock" and "clock color" feature by jerryscript ([URL="https://github.com/thekraven/android_frameworks_base/commit/7479afb07eaa5b0a1445d439904284bba9649ebd"]source 1[/URL] + [URL="https://github.com/thekraven/android_packages_apps_CMParts/commit/92bf8fce1a4d54dfb5076f17c456a8210b8a655e"]source 2[/URL])
- Kernel: Updated SmartassV2 with DooMLoRD's optimized version of the governor (I hope to achieve even better battery life) ([URL="https://raw.github.com/DooMLoRD/SGS-SL-i9003/GB/kernel/drivers/cpufreq/cpufreq_smartass2.c"]source[/URL])
- Kernel: changed taskkiller values to 6mb 8mb 26mb 28mb 30mb 32mb (1536 2048 6656 7168 7680 8192) -> values taken from the "balanced 3" setting from zeppelinrox's supercharger v6 (I encountered some slight issues with the previous values at multitasking) ([URL="http://forum.xda-developers.com/showthread.php?p=16635544"]source[/URL])
[B]cm-7.2.0-p970-20120620-KANG[/B]
- All CM7 commits up to build date
- Removed blur effect from popup menus (like the power-off menu) since it was causing slowness and lag
- Changed wifi default timeout to 5 minutes after screen goes off. cm7 default hardcoded value was 15 minutes
- Changed analog audio mixer to digital audio mixer. subjective listening result: less distortion and hissing via headphones
- Changed volumes for louder headphones and maximum speaker volume without distortion
- Added build.prop tweak for better battery life: pm.sleep_mode=1
- set wifi scan interval to 150 seconds to save battery (was 20 or 30 before)

- Added "smooth spinners" (the "please wait"-circle-animation)
- Created smooth indeterminate progress bar (the "infinite" progress bar). just applied some very basic photoshop skills for that
- A-GPS: added european NTP server (was north american before)
- Added more increments to volume bars for everything (music, ringtone, notification, alarm, calls, .....)
- Changed transition effects to lge-p970-froyo-stock because they look nicer and smoother
- Removed the android legacy libGLES driver, since it prevented the SGX530's graphics driver to do its job properly (should give a smoother overall experience + is proven to give an improved gaming experience)
- Kernel: added smartass2 governor and set default with battery-optimized values: DEFAULT_AWAKE_IDEAL_FREQ 800000; DEFAULT_SLEEP_IDEAL_FREQ 300000; DEFAULT_RAMP_UP_STEP 100000; DEFAULT_RAMP_DOWN_STEP 100000; DEFAULT_MAX_CPU_LOAD 66; DEFAULT_MIN_CPU_LOAD 33; DEFAULT_UP_RATE_US 48000; DEFAULT_DOWN_RATE_US 99000; DEFAULT_SLEEP_WAKEUP_FREQ 99999999; DEFAULT_SAMPLE_RATE_JIFFIES 2

- Kernel: changed taskkiller values to 6mb 8mb 24mb 26mb 28mb 30mb (1536 2048 6144 6656 7168 7680) -> values taken from the "balanced 1" setting from zeppelinrox's supercharger v6 ([URL="http://forum.xda-developers.com/showthread.php?p=16635544"]source[/URL])
- Kernel: tweaked tcp buffersizes to 4096,87380,256960,4096,16384,256960
- Kernel: tweaked SD-card readahead to 2048kb
List of included CM7 commits (cf. commit dates)
Installation, notes and bugs:
Known bugs:
Video recording:
Low frame rates in general (around 13 FPS)
Recording occasionally just stops after some time
Video playback: Hardware decoding is laggy (You can still use software decoding, which works fine, but consumes more battery)
FM radio:
FM radio puts the volume to the maximum at start-up and every time a sound notification occurs
After an incoming call the radio won't continue playing
Channel renaming does not work
SIP calling: The headset button won't work (can't mute or hang up calls with it)
Skype calling: Handsfree (loudspeaker) mode causes extremely low microphone volume
Bluetooth: there have been reports about random Bluetooth re-pairings, resulting in calls not working properly
Installation procedure and various problems:
It is perfectly possible to flash the kang over any other CM7 version (nightlies, kangs). Also, you can flash any other CM7 over my kang.
When you're switching to CM7 from a stock-based ROM: Few users reported problems of various sorts. If you experience any problems, re-install CM7 with a 'full format'. This should solve your problems in most cases.
The transparent / colored status bar feature does not work with all launchers or types of wallpapers. In ADW Launcher, the 'wallpaper hack' option must be disabled for the feature to work! Note that there is no solution out there for making it work with any launcher and wallpaper.
Few users have reported problems with getting a GPS lock. I have built a fix for that, which is already integrated into the ROM from version 2012-08-03 on. If you still experience problems: some xda users report that the following simple steps fixed their GPS issues completely: disable both 'Use wireless networks' and 'Use GPS satellites' in the menu 'Settings > Location & Security', exit the menu, and afterwards re-enable both options.
The FM radio turning on Bluetooth is NOT a bug, since the FM radio is integrated into the Bluetooth chip. It only appears that this is a bug, as the LG stock FM radio app hides that Bluetooth is activated. In reality, the stock FM radio app turns on bluetooth as much as the CM7 FM radio app does.
To those who are new to CM7:
CM7 is a powerful ROM that adds a lot of features compared to stock ROMs. Things which are noteworthy are a customizable power-widget, vibrate-notifications on established/disconnected calls, LED notifications, different lockscreen styles, volume keys to choose next/previous audio track, an ICS-like screen rotation animation, ascending ringtones, and much more. Many people may still think CM7 is buggy and unstable, but it is not anymore, since great progress has been made over the last months.
Miscellaneous tips:
Many apps that come pre-installed with CM7 can be removed if you don't like them. Check out this list of items to make sure it is safe to remove a specific app.
If you want to install other themes, search for CM7 themes on Google's Play Store or the xda forums.

There should be no problems with both, even though I did not test it. Just do cache and dalvik wipes.

thanks man keeping this great work:good::good::good::fingers-crossed:
Fantastic ROM, thank you. But I have problem with bluetooth handsfree in car (Croma with Blue&Me). First phone pairing is without problems, calls work. If I come later, phone connect to handsfree automatically, but when I have a call, opposite side does not hear me. I have the same problem with Temasek kang and with originall CM7. Stock ROM (Zeus) is without problem.

Even though I cannot exclude the possibility that there's a problem, there's no reason why that problem should arise. Don't get me wrong, I believe that happened to you
However, this sounds more like a "bad flash" or a corrupt file of the other flashed kang.
Maybe yes, i didn´t check MD5 of Temasek kang. Everything is possible.
EDIT: So i checked MD5sum now and yes, it was my fault, sorry for misunderstanding.
Unfortunately, the volume of the headset's microphone is still very very low in your rom. Can u fix it?

Just a suggestion, the word kang is not used anymore, unofficial would be the correct denomination.

This rom is smooth and battery is good when not used.... but when used, battery drain is huge! Is anyone having the same problem or am i the only one??

so that means there is something that is eating up my battery!! i am using sense theme...may this cause the battery drain??
this is the best cm 7 version i have ever used.
smooth, fast, no fc, no sod and it is very important good battery life.
thnx for your works.
please keep going.

I also found that sometimes our theme draining the battery faster. As an example, I was using ADW launcher (temasek 's default launcher) with its default theme. And these last 2 days, I used Buuf Guuf theme for ADW, I feel the battery draining faster.
Been using it for almost a day, feels and performs well, thank you very much!
However, the volume changing is buggy. When raising the volume, some steps decrease it, next steps increase it too much. The graph would look like: 1, 2, 3, 4, 5, 6, 7, 5, 8, 7, 9, 10. Not sure if it's just me.
I have been sharing my CM7/CM9/CM10/CM10.1 builds for galaxy s for some time in several thread, which culminated in the MackayROM. I continue now with JB4.2 for optimus black, based on this ROM for galaxy s. MackayROM is based on CyanogenMod sources, with several performance enhancements.
About Cyanogen: CyanogenMod is a free, community built, aftermarket firmware distribution of Android 4.2 (JellyBean), which is designed to increase performance and reliability over stock Android for your device.

If you run into errors, I may not be able to solve it!
If you know a solution to a problem, either upload it yourself to Gerrit Code Review or contact me through pm.
The ROM is based on CM10.1 with the following changes:
-Mackay Kernel
-Set of cherries picked from gerrit (differing by the day)
-Some handmade patches I did myself to the source code
Feature request are OK, but remember:
1. I try to stay close to stock
2. I will not include additional apps, unless they can be build from source
3. The time I spend on features depends on how much I like them myself

FAQ
Q. Process x (e.g. mediaserver/phone) is eating 50+% of my battery, what should I do?
A. Go to settings>apps>all and find the app which is causing the battery drain. Then delete app data and reboot phone. If it does not help, you can combine this step with clearing dalvik cache.
Q. I have problems with Play Store FC
A. Please install a recent gapps package (see e.g. http://goo.im/gapps)
Q: My camera is failing me!
A: Try this method: http://forum.xda-developers.com/showpost.php?p=41853069&postcount=950

Looks good indeed.
My hard drive got fried or something and now Im with no pc, is it really tested that it boots and it has working recovery?
I couldnt use adb if it bootloops and I dont know if this has e-recovery.
Thank you so much for bringing us this. I appretiate your efforts.

Actually, my wife does
That also tells something about the level of bugs. She is not an Android junkie and needs the phone for work. My cm10/JB4.1 ROMs led sometimes to complaints (crash) so I never shared those build. She is very happy with the JB4.2 build.
Only two things that are still an frequent issue: SD card getting unmounted and 3G battery drain. I am still hoping I can collect a logcat of the first. And 3G drain is 'solved' by using 2G when idle and only switch to 3G when needed.

I am especially interested in feedback on the updated vendor blobs (camera, gps, LED). If these work better than stock CM10.1, I can send a pull request to see whether they allow the v30c blobs into mainstream CM
Some of the additional features I added to this ROM will not be accepted by mainstream CM. Their policy nowadays is took keep the number of user settings to a minimum to have a clean experience. Although I like this (AOKP is too much settings for me), I do like some additional goodies on top of CM.
Another thing that may be useful upstream is the ROW scheduler. I have seen improvements on all phones I used this on, so I also added it to this p970 build.
