hate to break it to you, but looks like most of the things you have here can be found in this thread:
http://forum.xda-developers.com/showthread.php?t=1227269

Thank, please keep developing...

Will the build.prop tweaks still work on ICS?

Nice scripts they are working but if you want them to be safe and without conflicts try removing the lmk settings before Ram differs on most phones
Example: Galaxy ace has 278 mb of ram and Lg optimus one has 512 (Basically is 478 or something).Those lmk settings will mess LG's ram

Actually, LMK settings should be standard as it represents free RAM (rather than total available RAM).
Only thing that matters for an LMK is that it should be tweaked along the Dalvik LMK. Only tweaking one or the other makes the LMK inefficient.

Hi what I would like to know is that the netspeed tweaks do those help in the edge speed. Also the internet tweaks do i need to enter all of those for the edge speed gain or only the line with the gprs.

how to use this script , i mean how to save this file??

I am using must of them so no need to change it.Thanks Frank for collecting.

If you don't know how to apply them just install a rom that surely has some of them

Nice list.
I think ro.ril.disable.power.collapse should read
Code:
ro.ril.disable.power.collapse=0
because you want the power collapse to happen to save energy. Also, all commands should be lower case. Therefore it should be
Code:
debug.performance.tuning=1
video.accelerate.hw=1
with 'd' and 'v' instead of 'D' and 'V' at the beginning.
Further, I use
Code:
dalvik.vm.startheapsize=4m
which in my experience reduces RAM usage by approx. 15 MB on startup.

Nice list.
I think ro.ril.disable.power.collapse should read
Code:
ro.ril.disable.power.collapse=0
because you want the power collapse to happen to save energy. Also, all commands should be lower case. Therefore it should be
Code:
debug.performance.tuning=1
video.accelerate.hw=1
with 'd' and 'v' instead of 'D' and 'V' at the beginning.
Further, I use
Code:
dalvik.vm.startheapsize=4m
which in my experience reduces RAM usage by approx. 15 MB on startup.

ro.ril.disable.power.collapse should be 1 to disable the power collapse

in that link it is written

The sense says it should be=1, so what do we use?
Another thing, we can't use all the build.prop lines of that link is this right?

Just use the tweaks currently in the OP. I believe thefrankenstein will only state the tweaks that work.

Nice work!
I'd changed the media builds yesterday, however, now i can't playing youtube's videos because when i press play button the Mobile become frigde and i only can to turn off pressing long the power button.
Can you give me thr factory status? I didn't a back up file :s
Thx!!

When you edit build.prop, the phone automatically saves a build.prop.bak in the same location, just under your build.prop. Just rename it to build.prop and delete the bad one.

[Q] Faux kernel init.post_boot.sh customization

This is, i´m reeally noob, and do it just for fun and have muy sensation the way I like, so I want to know just the basics to do that.
Just added stock frequencies to init.post_boot.sh of faux kernel, and I wondering, how to control the transitions or steps of the frecuency scaling, I found this lines, but really don´t know if they will work. Some of them are already in my file. But I don´t know whats the function of sampling_rate, up_threshold, and sampling_down_factor, and if they will work on intellidemand governor.

[Q] Init.d problems

I'm trying to make a script for my kernel settings on boot but can't seem to get them to apply it only applies the GPU clock, the max frequency, and voltage table. The CPU boost speeds, the go hispeed load value, and my I/o settings don't however. Is there something I'm doing wrong? At the end of the script I even have a line for it to create a text file verifying that the script ran but it in fact does not. There is no other kernel apps set to run at boot, and I've tried editing a vomertweaks zip with my settings and it won't apply either. Can anyone give me some tips?

What is $soc_id equal to? Now we have to audit trail to see what and when $soc_id has been set to, which will open up another can of worms to see when it was initialized to, and what are the implications of having $soc_id set to a certain value, rather than another further down in the init process? Why can't we just extract all of the actual information to the boot process and leave the other junk (support for CPUs which are 5+ years old, unused features, etc) behind?
Enter Ideal Init. What Ideal Init is, consists of some changes to your device's stock kernel, and some changes to your device's stock ramdisk. Once you make the changes to the kernel and ramdisk, you create a boot.img with the new and updated kernel and ramdisk, and flash it to your device. The changes you just made to the kernel and ramdisk now allow the system calls made by your device's init.*.rc scripts and init shell scripts to be logged and dumped for later use.
From there you can dump your device's logs using the dmesg command, and run the ideal_init program on your computer to interpret these intercepted system calls and output a single valid init.<device>.rc. Then you can revert back to your original setup.
Basically, this program turns all of these init scripts and these init shell scripts and extracts only the information that was actually used in the boot process to create something like this

Hope this helps the device bringup for future ROMs
