Init.d scripts - AT&T Samsung Galaxy S II SGH-I777

Here are the init.d scripts that I have been using for Siyah. Please note that 95% of the scripts were done by Pikachu's thunderbolt scripts and I have modified then to my liking. Thanks to Pikachu for the hard work he has put in for the developement of our devices. For those that will use these scripts please use them with caution! I am not responsible for any damage done to your phone! You are free to use these as you wish, adjust them to your liking. The s70darkyzipalign, s98cfs, s98systemtweak should be universal for all setups and you do not need to adjust these init.d scripts. The one you need to be aware of is the s98bolt1 and screenstate_scaling script. The s98bolt1 script has cpu freq. steps set at max 1504 min 100. Scaling @ max 1304 min 200. The voltages for these steps are pretty aggressive and may not work for your device so please PLEASE adjust them accordingly. This script will also set ondemand/sio as default. You can replace those as you wish. GPU is set for 40, 133, 267mhz. (Andreilux's settings, Thanks Andrei) Sched_mc and AFTR have been enabled for some extra power saving.
Screenstate_scaling have been modified to set as Ondemand as wake governer and Powersave as sleep governer. You can adjust these as well. The scripts are pretty self explantory and you can adjust these values using root explorer and using the menu in root explorer to "open in text editor". Or you can you wordpad or notepad++ on your pc and adjust them. Save the scripts to your phone. Using root explorer copy the init.d scripts to /etc/init.d. Paste in this directory and set permissions as rwx,rwx,rwx and reboot.
I am sure I missed some things as I'm kind of in a hurry. Please pm me if you have any questions or need help. I have used this setup for quite some time now without any problems. Battery life has been amazing without sacrificing performance. Oh please do not use VC to save boot settings as these will clash. Everything in the init.d scripts will do the same as VC as long as you adjust them accordingly. Good luck and happy flashing/modding!
P.S. After downloading the file remove the .txt extension in the files before using. Thanks!
Here is the link to the Originator and Creator of these awesome scripts. Thanks Pikachu!

I just want to make sure before I utilize these. I need to use a file manager to place these in /etc/unit.d folder without the .txt correct?
Should I remove the existing scripts as well?
Edit: do these scripts completely take the place of voltage control and setcpu? I wanted to get all of my questions out of the way

These seem awesome. Can't wait to try them out

Everything you posted is correct. Please keep in mind the voltage settings are a little extreme. If you think or know your phone can handle the UV then just drop them in without modifying. But if you're not sure add +25 mv to each step.

I almost gaurantee your phone will sleep like a baby. And fly like the wind when in use.

Thanks for the scripts!
I've also found an interesting script at 9100 Siyah Kernel topic ( http://forum.xda-developers.com/showthread.php?t=1263838&page=1813 )
I got sleep of death by using below script so you may want to check voltages setting before using it.

Steve you are the man! Thank you for bundling these scripts all in one place. Everything is smooth and my phone is sleeping like a baby so far.

What ROM are you using?
Can these scripts be used on Unnamed?

---

Unit.d generator in the i9100 forum works great for this.
Must script manager be used to give these scripts root access to work?

I believe these scripts are universal and can run on siyah or entropy dd. Can someone else confirm this?

---

Sorry guys for the late reply. Busy at work. Yes these scripts are universal for any ROM. Just make sure your kernel supports init.d. Siyah and Entropy both support them.

No, some of them depend on tunables in Siyah I haven't ported over yet.
Personally, I would not recommend putting voltage settings in a script that you distribute to the public, as voltages are device-unique.
I'm also a firm believer in a number of small separate scripts with descriptive names, instead of a "megascript" that does it all - harder to analyze and harder to pick and choose.
I'll take a look at the specific script contents when I have some time.

---

thx for clarifying entropy. i did state specifically about the voltages and they have been modified to my likings. so for now use for siyah kernel. and once again pls adjust the voltages to values that your phone can handle. some phones can only take a -25 mv from stock voltages. s98bolt1 and screenstate should be used as a base only. adjust them to your liking. the other scripts are system tweaks and are universal for most roms.

Thanks for this post Steve. Im sure once I get a handle on these tweaks and applying them I will greatly benefit from them!

---

No problem. Trying to help out anyway I can. I know all these scripts can be confusing and a headache. I noticed a lot of people asking how to make scripts and OC and UV settings so why not make them avail for the general public. It's just a good base to start off with for siyah users. If anyone has or needs any help in reading the scripts and how to adjust them let me know.

---

I could ask ya a million questions..but I wont lol. Just trying to do lots of reading here..and on Google to learn about scripts..init.d..OC and UV. Sometimes I think I got it...but then i get all confused. The only script I have now is the V6. That one just seemed like I could handle since it basically walks ya through the entire process. And to be honest..not even sure i notice a difference.

Trust me, it made a difference. It's nothing flashy, and nothing some people would notice, but it did.
Nice post stevehkim, I may give these are try.

If I may..s70darkyzipalign, s98cfs, s98systemtweak...Are theses kinda like OC and UV or just minor system tweaks? I tried opening them and taking a look...but have no idea what im looking at. I admit, I am not the smartest person thats for sure

---

They, from their titles, are system tweaks. I haven't looked through them, so I can't tell for sure.
Edit: Steve, you might want to post a brief description of what each script does, which can be run independently, which need to be run together, and most importantly how to implement them.
Just a suggestion to cut back on confusion and potential fights
