Yeah you should be rooted. And yeah that's a different method. Tell you what, try downloading an app that requires root and see when you launch if it prompts you for root. A superuser popup should appear.

ROM = term loosely used for operating system. When we say flash ROM, we're generally referring to a custom ROM, i.e still Android but modified/developed by someone/people.

You have the one that looks like stock : CynogenMod
You have the one that looks, erm, abit like iPhone : MIUI
And you have ROMs based on samsung's ROM : Checkrom, Turkbey, etc

Kernel = The jazz which manages the internals of your phone, like your CPU and what nots (excluding connection, that's handled by modem/baseband).

So once again, ppl out there "cook" kernels up based on existing kernel codes of samsung and they add/modify stuff. Purpose of flashing this is for better peformance/battery life

Ah exact same setup as you atm

Haha can't tell bro, haven't used it extensively + I've never used RP for a day yet

Need antt's feedback, assuming he still keeps Siyah over the coming week

I'm on ondemand for Siyah, how do I go about setting a screen-off limit to 200mhz

Not particularly versed in script, can briefly walk me through it?

Hmm schedulers won't affect it right?

I reset CPU spy and immediately turn off screen. I still get frequency readings in the other ranges. Over 10 seconds in 500mhz

I'm on siyah .13

Edit : Hmm I'll go test it properly again. Did off secure mode so I don't waste time entering pattern and all to unlock device and get to CPU Spy. Did it over few mins and did get some readings in 500 and 800, but a little less. Maybe when I on and press CPU spy I guess (I offed the screen in apptray, so press on and terus press CPU Spy)

Further edit : Got more than 10 seconds after 5 mins off procedure above on 800mhz. Hmm doubt pressing on and hitting CPU spy takes more than 10 seconds. Not too sure

But thanks for the tip lulz in siyah has 200mhz cap for screen off too?

Hmm not sure where my 800mhz is coming from though. Lol I'll see if I can set it somewhere. Hmm maybe I'll try lulzactive since that has an app and makes it easier for me

But if ondemand and I wanna tweak it, where do I go to?

Ah ok.

Can I use text editor in root explorer to edit values in the scripts?

Cool thanks, should be fairly do-able then.

Time to google up what's what

K sorry for asking this, but I'm a little clueless.

So I'm guessing I go to thunderbolt screenstate scalling. Then down to point 4 where


I remove # from the 2 echo lines, and change the max and min frequency to 200000?

Not to say super alot. didn't monitor off screen long enough. About 15 seconds over 5 min off screen time previously.

Oh meaning when entering into sleep it has to go up to 800mhz first? Thought as long screen is off the max freq or whatever is 500mhz etc

Ah ok, thanks for clarifying. So regardless it'll go to 800, before going to sleep, then subsequently on wake it'll be at a max of "x" value, before going to 800mhz right before sleep, right?

Ah found it. It's at 500000.

Erm, what's the difference between the previous min/max scalling vs suspend_freq.

Notice they're in different locations also (cpu0 vs cpufreq)

Ah ok, some governers have no deep sleep?

Btw I went to the directory itself and saw the 500000. Assuming I want to change it I should be finding the script somewhere, and not manually amend the file in that directory? If so, where's the script ah >_<
Sorry real bad at this script/int.d stuff

Ah thanks

But basically don't amend the file in that directory kan? Always use script to echo?

Haha I'm actually waiting for the app as well

But assuming you don't stick to siyah in the future, guess it's good to know a little about scripts, although there's a learning curve

Aduhs pengsan

So add
to system tweak at te end using notepad++, then delete the old one, move new one into init.d balik with root explorer, and change permissions?

And reboot. Got it. Init.d runs at boot right? Don't need to use script manager or whatever to run it as root etc

Hmm true, I'm gonna leave it for now, tak mahir script x.x

But assuming wanted to add, have to add to a specific section, or can just add line below as another script running at the end?

And say I open a script file, some scripts are left margined, while others are indented inwards. Does the indent and all make a difference?

Looking through the scripts, gotta be real thankful to you guys who put stuff like that for us. Gosh that's alot of scripting

Ah add to the section where ondemand script is? Like below this?



But that's if up_threshold something (don't know what -e is), not related to suspend freq. But assuming that script looks for the value, executes script, then guess adding it below there is fine as well, since it'll run anyways?
