Well look who it is lol

I use callrecorder on an EVO now, you just have to select "Other" in phone list and make sure you tap the setting for three Kernel Patch... But it does work, you just have to fool with the settings

I don't really think we endorse that here, read the official get it off your chest thread and you may understand why.

The whole 2way thing is intriguing me. I used the built in voice recorder app that came with my ROM during a phone call and, while it wasn't real 2 way call recording, if you had your call volume up high enough you could clearly hear the other party in the recording. Just much quieter than you. Of course anyone could do that with any kernel: I'll keep investigating a free (and above-board) way to do real call recording.

Thanks for the link, an honestly interesting read! I myself have donated to developers, charity, and the homeless I come across. The first thing I can say is the majority of the times I pirate something I wouldn't pay for it either way so the persons losing nothing from me. Also I like to find a nice balance of work put in and need. Regardless of how much work is put in some people need the money more than others.

I've been running v6 for two days now on Mikg 3.11 and for some reason I can get it to stick on the SmartassV2 governor which is suppose to be the default governor. It keeps resetting to Smartass whenever I exit out of SetCPU. I've tried rebooting, but haven't had any luck. Phone seems to be a little sluggish on Smartass.

Edit : I fixed it! Phone is running better already!

You guys wanting 2-way call recording want this:
https://play.google.com/store/apps/details?id=com.skvalex.callrecorder&hl=en

If you look in the description there's a link to here and an available free trial:
http://xdaforums.com/showthread.php?t=1441643

OK, tried it, works awesome. Actually if anything the near side is too *quiet*. But one way or another it is obviously true two-way call recording. I used the trial apk linked at bottom. Not sure I need this bad enough to spend ten bucks going forward, but if I ever do need it, I'll know where to go. Thanks!

by the way jettubby i thanked you by mistake have a nice day.

Just so everyone knows I noticed that adjusting the volume in call adjust the source recording volume also, so that may something to do with low.recordings, on the other hand, cranking that volume causes some distortion in the recording.

    Underworld Sense Kernel

    This is a little something I have been working on. Thank you to those who tested under the "saturday morning" thread. Hopefully I will be able to continue to improve this kernel and add in additional modifications as time goes on.

    And please remember this is a work in progress, so please let me know your results.

    What's in this Kernel

    Features

    Stock Kernel 2.6.35.10
    Patched to 2.6.35.14
    Enabled Wireless N
    Perflock Disabled
    HDMI Fix

    Undervolted to LEE Kernel Settings (tiamat)
    Compiler Optimizations
    Superior Battery Charging (SBC)
    Boosted Audio More
    Extend Wifi Range
    Removed CIQ (Please note - you may encounter problems if you rom has ciq in it)
    Flashlight Cutoff Reduced to 10% from 15%
    Increased GPU Memory Allocation
    CIFS (compiled as module)
    TUNS (compiled as module)
    Front Facing Camera Fix (for inverted) (should work on all gingerbread sense)
    Swap Enabled
    Fixed Hotspot for some users
    2 Way Call Record
    Memory/Scheduler tweaks
    RCU Tweaks
    LZMA Compression
    Removed Some Debug Code
    Enabled EXT4 Support (applied performance patch)
    Add ZRAM (Lzo_compress/decompress) as modules)
    Add HTC Kineto_gan support for wifi calling
    Reduce vfs_cache_pressure from 70 to 50
    Wifi is PM_FAST in standby
    Increased Min Voltages from 925 to 950

    Governors

    SmartassV2 (set as default)
    InteractiveX
    Intellidemand
    OndemandX
    Smartass
    Conservative
    Ondemand
    Userspace
    Performance
    Interactive

    Schedulers

    SIO (set as default)
    NOOP
    Deadline
    CFQ
    v(R)
    BFQ

    Instructions

    Apply with your preferred custom recovery.

    For Kernel Install
    Make sure to wipe Dalvik Cache and Cache.

    For SBC
    And make sure the phone is fully booted before plugging it in.

    For HAVS with sysfs interface
    You will be able to use Vipermod to change the voltages. To be able to save changes you will need a rom with init.d support baked in. The kernel has already been undervolted, but since everyone results vary depending on their devices, this interface will allow you to drop it lower, just like you have been able to in the AOSP roms.

    For Audio Boost to turn on and off
    Code:
    Audio Boost On
    echo 1 > /sys/kernel/audio_boost/aboost
    Audio Boost Off
    echo 0 > /sys/kernel/audio_boost/aboost
    Query Audio Boost Status
    cat /sys/kernel/audio_boost/aboost
    For USB Fast Charge to turn on and off
    The below code will toggle it in the terminal, but a cool way to turn it on and off would be to support the original dev who put this mod together, chad0989 by purchasing his widget that controls this version of usb fast charge as well as the patch version. LINK TO WIDGET
    Code:
    USB Fast Charge On
    echo 1 > /sys/kernel/fast_charge/fast_charge_usb
    USB Fast Charge Off
    echo 0 > /sys/kernel/fast_charge/fast_charge_usb
    Query USB Fast Charge Status
    cat /sys/kernel/fast_charge/fast_charge_usb
    Thanks to Capt_Throwback for finding out a reason for some of the lag complaints. It appears that the Vipermod script installs an older copy of busybox onto the phone. I have attached a copy of the vipermod install script that does not install any busybox.

    Updated OP to v08.

    Please note specifically the addition of EXT4. if you use a2sd you can type: a2sd check
    in the terminal app, and if it says EXT4 yes, then your rom and kernel now can run EXT4.

    I have also compiled some No HAVS versions for those who have difficulty running underworld
    please try these out, their voltages can not be modified, hopefully this will allow others who have
    been running classic/nitrous due to their phone's restrictions to have some fun on underworld.
    Please let me know how this version runs for you, thanks.

    I think I found a flaw in many of the implementations of init.d support in sense roms..

    It almost appears that init.d only runs on first boot and then is disabled..

    Example. If I format all partitions except sdcard, flash a fresh ROM, flash my test kernel that includes a script, then boot, the script makes the changes.. If I then make changes in the script and reboot, I get no further changes..

    Example 2. I format all partitions except sdcard, flash a fresh ROM, do a first time boot, go back to recovery, flash test kernel with the script, upon next boot, no modifications are made.

    When I get time I'm going to play with the ram disk of a ROM, repackage it with the setup I found in CM7, and see if it works... If it does then we have a solution to get rid of needing to use script manager and other apks.

    though if that is true, would need the ROM devs to update their roms... Though I could make some boot.imgs for popular roms...

    So I am excited to see if this theory works..especially since the test kernel has a configurable file that let's you turn on and off audio boost, usb fast charge, governor, scheduler, etc

    Updated to v0.3

    I was trying to figure out how to get the front facing camera to work before releasing, but i haven't cracked it yet, and with the updated source up to possibly a month or so out I figured I should update what I have done already... please let me know if smartassv2 behaves better now


    list of changes.

    Removed CIQ
    Extended Wifi Range
    Flashlight cutoff reduced to 10%
    Increased GPU memory allocation
    CIFS (compiled as module)
    TUNS (compiled as module)
    Tweaked Smartassv2
    Fixed SIO to be default scheduler (again, lol)
    Added Interactive Governor

    Lets use this post finally

    Tips and Tricks

    1. If you are usinig V6 SuperCharger with kernel I/O tweaks. Please uninstall the I/O Scheduler tweak. Failure to do so may casue random reboots. (Thanks Kelldane)
    2. Please navigate to the system/etc folder and scroll down until you find the init.post_boot.sh file and either delete it or move it to a safe place on your sd card. More Info (Thanks Leeboy)
    3. When using smurf, do not use the battery saving settings for Smartass V2 otherwise in most cases it will generate lag on that governor. If you open the 45smurf file in etc/init.d and remove the section with the governer tweaks the lag will go away after reboot. (Thanks Pennie77)
    4. Ensure that your busybox binary is up to date. (Thanks Capt_Throwback)

    Undervolting

    havs kernel has an upper and lower range, while the normal kernel has a static range.. i pulled from my source code the havs voltages and commented after the line the original voltage.

    { 19200, 950, 950 }, // orig voltage 1050
    { 128000, 950, 975 }, // orig voltage 1050
