Give me one moment, making you a deletion script. - Attached

Now we need to get back into recovery. You should be able to do this right from the Exclamation sign. Volume Up + Volume Down + Power Button. Hold till you see your recovery screen.

Then go to mounts/storage and mount the internal sd. This should allow you to move the file I have attached over. Then flash it, and reboot.
[AT&T Samsung Galaxy S II SGH-I777] prince_niceguy:
you have to mount the sdcard fro mount menu and then run the bolt script.
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
Entropy's SDCard mounts differently in his kernel. This script does not work with it. With SiyahKernel, should extract correctly.
[AT&T Samsung Galaxy S II SGH-I777] ddominator:
I'm on unnamed 2.2.1 with latest Siyah. I tried 0.23. It doesn't get pass the boot and I had to restore.
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
I just tried that today. Do you happen to have any other scripts or voltage control programs installed?

What scripts do you have in your init.d folder?
[AT&T Samsung Galaxy S II SGH-I777] justbenice:
Maybe you should wait? I notice that it take very long time for first boot
[AT&T Samsung Galaxy S II SGH-I777] ddominator:

Anyone wan't to test 0.2.4 before I release it on main post?

Hoping this increases 3g/4g speeds, so run a few speedtests before flashing. Also underclocking the cpu to 1100Mhz.

Save more juice but hopefully not notice it any slower. Been testing it for about a day with moderate usage, can't notice anything slower.

Also I am trying to drill down to the tweaks that makes everyone happy with while still saving a decent amount of juice (Orange Juice pref.). I am going to be trying things for a while before I throw a 1 in the front of the version.

I might just try 1300Mhz next too.

[AT&T Samsung Galaxy S II SGH-I777] wbcollins:
I can't boot after this one either. As a matter of fact...things weren't so great after I reinstalled 0.2.3 (which had been working fine) after I failed on 0.2.4. I ended up with lots of force closes. Something must have lingered after the 0.2.4. Just wiping caches and reinstalling didn't stop the fc's. Ended up doing a factory reset (no big deal). So I have a perfectly clean miui/siyah config.
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
I'm sorry man. I will be installing MIUI and playing around to see if I can figure it out. Thanks again for testing!
[AT&T Samsung Galaxy S II SGH-I777] TechSilver13:
I'm on the latest miui and siyah. I flashed 0.2.3 and its working fine. I also added v6 supercharger afterwords. Edited the voltages and range via your instructions and everything is running great. Thanks a lot.
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
Thanks for the feedback, much appreciated.

As for collins: I have done a hour of random tests with MIUI /Siyah/v0.2.4 and all seems to be ok (For now...). It's possible I threw too much at you, I know you went threw 3 different tweaks I have been playing with. Some were doing build.prop testing. I need to do more day to day use, can't say much though when I have a perfectly clean install with nothing else on. Once again, thanks a ton for gambling with my tests.

I am going to put a experimental version on main post to get some more feedback. Backups first of course.
[AT&T Samsung Galaxy S II SGH-I777] wbcollins:
The experimental build took for me this time. I'm not sure what went wrong before,but it seems stable for me now. thanks for your hard work!
[AT&T Samsung Galaxy S II SGH-I777] Gutterball:
Ok installed the .2.4 exp on a hellraised omega rom and as usual just took awhile to boot definetly over 3 minutes. As far as speeds I really don't know because my first test showed 2.5 mbps dl (which is basically normal) but my 2nd test showed a ****ty 400 kbps lol wtf. Now a 3rd test put me back to the 2.4 range so... I really have no idea what to make of that?

As for stability so far so good no fc's or anything of that nature seems fine right now. Thanks, CWC3

As expected 0.2.4 brought my benchmark speeds down a bit compared to 0.2.3

I'm not noticing any network speed difference other than maybe lower pings, but the upstream and downstream seem the same. This could be due to tower limitations;

Ex the towers near the library supports h+ (21mbps theoretical) and the tower near my house supports only h (14mbps theoretical)

Ill report back about battery later today

Btw I'm running:

Cm7 02042012

Siyah 2.6.11 red

Init.doh 0.2.4

Conservative/noop

Nothing else changed.
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
This script currently doesn't increase or touch your download speed. Maybe in the future I will try something with the build.prop again.

Thanks for the feedback people. Much appreciated!
[AT&T Samsung Galaxy S II SGH-I777] Nuskul:
Flashed 2.4 over task's rom, with siyah 11 everything works well. Did a few speedtest runs and noticed about 0.5 megs faster than before. Was consistently about 2mb at home now 2.5. Going to inlaws for superbowl where I hit 4.5 to 5mb, will check and report back. Very interested in battery savings, typically I see over 2 days with moderate use. Will report back on that also.

Thanks for your hard work and for feeding my flashing addiction!

Experimental version working on SHOstock. Thanks!
[AT&T Samsung Galaxy S II SGH-I777] iXNyNe:
Gotcha, saw it mentioned so I didn't know it was taken out before I got to it.

Anyways I'm getting consistent sleep death with 0.2.4

Phone enters deep sleep and then is not responsive to power button unless held until reset (screen doesn't come on with just a press)

Used uninstall and then flashed 0.2.3 and no more sleep death. Flashed 0.2.4 again and it comes back. Tried as is and with conservative/noop.

Back on 0.2.3 for now

Releasing .2.5 exp. I chose not to delete init.d folder yet till I do more testing of how that will handle on roms such as MIUI/CM7

v0.2.5_EXP: Bumped most voltages up 25mV, should be -50mV still on most. changed deepsleep_cpulevel back to 100-800mhz/400Mhz bus - hopefully this will fix most SOD's

Wow I drove 45 mins and only used 10% battery life with nav on and screen on. If I flash a new kernel, do I need to rerun the script?
[AT&T Samsung Galaxy S II SGH-I777] iXNyNe:
Flashed 0.2.5 and new siyah 2.6.12 and switched to conservative/noop, no more sleep deaths, battery life seems stable.

Also everything seems to be working well and smooth, no lag or freezing on anything I've tried.

My list of things to try includes (but is not limited to);

The market (3.3.11)

Little empire (good gpu test)

Antutu and quadrant (just to make sure they finish and scores aren't vastly different than previously experiences whether its good or bad)

YouTube (nice to know its not messed up after flashing something new)

Camera (see YouTube)

And speedtest.net app (to be sure nothing there has changed for better or worse)

Whenever something is different, good or bad, I report back after repeating and confirming.
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
Thanks for the feedback! If .2.5 keeps doing alright by you guys, I will make that the new stable and start experimenting with some more stuff.

Not to my knowledge. Unless Siyah deletes thunderbolt! scripts, were fine. Only thing I would do is give the phone another reboot after clearing cache.
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
Added a basic script for people who want to try out Geko's settings. Tweak the init.d script to your liking. Check post #2 on main page. This works fine on Entropy. And if you are on siyah, you can combine with Init.doh. (Replaces s98init_doh)
[AT&T Samsung Galaxy S II SGH-I777] iXNyNe:
so the only real reason to flash the gekoh script is to undervolt MORE than what init.doh already does? (as i understood 0.2.4 and below used almost an exact match of geko's settings, 0.2.5 has everything +25)

other than that it does nothing different?
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
All gekoh does is undervolt a little more than 0.2.5. It doesn't include any thunderbolt scripts or gpu tweaks etc. Pretty much its just a 1 zip option to get you to the Voltage Control settings he uses. It can be flashed over init.doh & you will just lose the tweaks I did in the s98init_doh file.
[AT&T Samsung Galaxy S II SGH-I777] justin860:
In your opinion which version will save more battery 2.5 or the 2.3
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
Even though .2.5 the voltages are higher, it is clocked at 1000Mhz to save some juice. Also has a few more features to help with handling 2nd core/sleep.

Making 0.2.5 the stable version now, and dropping the voltages back down to geko with 2.6 Exp. Let me know how you folks like conservative. Hard for me to tell.
[AT&T Samsung Galaxy S II SGH-I777] evodon84:
Thanks CWC3, I installed 2.6 exp and my phone still works :)
[AT&T Samsung Galaxy S II SGH-I777] cwc3:

[AT&T Samsung Galaxy S II SGH-I777] chase10784:
So I installed this and it seems to be working ok as of now. My question is what is the difference between Conservative/noop and ondemand/cfq? Which combo is better for battery life? I dont know much about govenors and schedulers.
[AT&T Samsung Galaxy S II SGH-I777] iXNyNe:
0.2.6 is perfect for me. Exactly what I want!

Works great and settings are where I prefer them to the T
[AT&T Samsung Galaxy S II SGH-I777] :
I really wanna try this with Turkbey v33, but he has a lot of weird scripts in there. He doesnt explain what they do so possibility flashing 0.2.5 might cause instability. If anyone running v33 has any info on what the weird named scripts might do, please share.

Using 2.7 so far everything is great and I'm noticing 25% more battery life then normal I will post results when I reach 5%
[AT&T Samsung Galaxy S II SGH-I777] mrRobinson:
if i install this can i still use setcpu to set a 1400 speed. Some apps I have seem to run better with that now but i'm on unnamed with siyah 2.6.11 and none of these scripts.
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
If you open the init_doh file, you could change the Max CPU from to 1400000. Then you wouldn't need to use any apps.

On the main post I wrote a few questions and answers that will help you edit that file.
[AT&T Samsung Galaxy S II SGH-I777] sfms:
Hello, if you have time, can you walk me into how to change the Max CPU? (I want to change the scripts themselves, not use setcpu or anything) Thanks in advance!
[AT&T Samsung Galaxy S II SGH-I777] iXNyNe:
I notice on 0.2.6 the gpu voltages are 850, 850 and 950

On 0.2.7 changelog says its 850 900 and 950

Geko's settings (which only have 2 states) were 800 and 900 (have since changed)

For me (and many others) geko's settings froze up a lot so I upped the 900 to 950 and that solved it (and his post now has 800 and 950)

From my experience lower voltages don't cause lag (gpu or CPU), just freezing, so I'd say if you're trying to avoid lag you should up the cpu clock speeds before upping any voltage settings.

Also keep in mind voltage jumps cause lag and freezing

Ex; if you know your CPU can operate safely on 200mhz@900mv and can also operate on 500mhz@1200mv but you still experience lag or freezing its likely because of the massive jump in voltage, so you'd be safer to either up your 200mhz voltage or lower your 500mhz voltage (at least this had been true on other devices with the same scenarios like governors and such)

I'm smooth sailing on 0.2.6 and I'd say the 114 gpu could be safely dropped to 800 (leave the 160 at 850) I'd say maybe bring 1200 back for smoothness but keep conservative/noop for battery

I don't know if this applies either but I remember existz talon kernel on the captivate let you overclock but he just swapped the top frequency from 1000 to 1200 so there was no more 1000, the explanation was that the system was built to handle a certain number of CPU states and adding more caused more issues than it solved. (Different processor different chipset, probably doesnt apply here) So my mindset there is we have a 1.2ghz processor why not let the system use it? Just control how often and for how long its used by governing it.

Just my thoughts on the matter.
[AT&T Samsung Galaxy S II SGH-I777] cwc3:
Thanks for the info. I decided to bring the cpu mV back down to geko that version, since I don't believe it was the reason for most SoD's.

The reason I upped voltages on GPU .2.7 is because I upped the GPU Mhz also. Not quite sure why I played with 160Mhz voltage though, so thanks for catching that. Some people reported their screens changing color, that's why I brought it up a little. Though no one has done that yet with geko, so I will change it back to 800/850/950.

The 950mV I have had at least since .2.4. The lag was because the gpu/conservative. TWLauncher loves ondemand. I will play with Conserv/Noop a bit and see how it does. Also .2.7 is @ 1200Mhz, which is where I will be keeping this script for at least another 10 releases.

The thunderbolt scripts play around with the sampling of our cpu, that's why I don't touch it at the moment. Trying to keep those to stock TB settings atm.

Thanks once again!

Check the main post. Look in the questions area, that should help you a bunch. If not, let me know!
[AT&T Samsung Galaxy S II SGH-I777] iXNyNe:
What is CPU sampling? I've heard the term a lot but never got a definition.

Also I see your point with touchwiz for the sake of keeping it universal. I use golauncher with sphere transitions and as much lag inducing awesome looking settings as I can find and conservative has never caused lag for me.

but again for the sake of keeping it universal if conservative wont play nice with TW.

Will update a little bit later on how its going. Any noticeable battery life changes probably wont be noticeable until tomorrow though.

[AT&T Samsung Galaxy S II SGH-I777] cwc3:
TB has sampling commented out from what I can see, so in .2.8 I will include it and see if we can start playing with ondemand a little.

You want the noop? You can't handle the noop.

Uploaded 0.2.8, giving ondemand/noop a try.

No need to clean, it deletes/overwrites each install. It also cleans cache every time too. Just don't forget to reboot twice and you should be fine.

Hi! I do Integrated Circuit (IC) design for my living and am well aware of voltage conventions! Thanks. Your answer is wrong though. Milli volt (mV) is not one millionth of a volt. It is rather one thousandth. Milli meter, Milli volt etc are a scaling of 1/1000. Micro volt (uV) is one millionth of a volt.

The intention of original post of mine is not so much about pointing out the typo. Rather it is to make sure it is only a typo in description and not the script as I am debating of trying out those scripts.
[AT&T Samsung Galaxy S II SGH-I777] iXNyNe:
I'm sorry for coming across rude, and actually feel a bit silly mixing up the metric system (I'm a frequent praiser of its common sense, but now that I think of it it seems silly to associate Milli with thousandths as they did, rather than millionths)

Good intentions don't mean a thing when combined with unpleasantness and of course false information (even if I was unaware it was false).

So I sincerely apologize for my post.

On topic, these scripts are definitely worth trying, they are geared towards being safe, stable, smooth, and battery friendly, and thus far I'd say they do an amazing job regardless of whether the people using it know or understand the numbers involved or what settings are used.

It is best to get your own undervolting settings rather than use one from someone's (as phones differ to how much one can undervolt it).
