I tried setcpu, but the minimum CPU speed is only 300MHz. Cannot go lower edi. Besides, there is no voltage control, which means CM9 stock kernel does not support UV. Is horsepower kernel good?

Also, in setcpu, there is something called I/O scheduler. it has noop,cfq and deadline. What do they mean? setcpu's website does not offer any explanation on this.

Once again, thanks a lot for all the info!

Hehe, no la. It's just that I want to squeeze every single drop out of my battery. Gonna do more research on horsepower kernel. Alright, I checked that already. Thanks!

I'm on CM9, stock kernel now. If i flash Horsepower kernel, then what do i do when I want to flash the latest nightly? Will it cause any problems? or will flashing the latest nightly overwrite the horsepower kernel?

Shouldn't be a problem right? as in, flashing new ROM will overwrite kernel

I'm a G user. Now you got me confused. No problem until I re flash rom? Means once I re flash rom, the kernel will be overwritten, right? That's what I understand so there won't be any problem after flashing new rom, except that it will be using the stock rom kernel.

thank you!

I think you have to take note of whether your phone is G version (I9100G) or non-G version (I9100) as well.

If it can reboot and you can see Superuser icon, means you now have root access and your phone is okay!! Congrats !

Anyone dual boots ics and jb? I want to ask, if i use cm9 as primary rom and jb (cm10) as 2nd rom, how do i flash GApps to my 2nd rom (CM10, jb)? Any ideas?

alright. Thanks!

Yes. http://forum.xda-developers.com/showthread.php?t=1680851

Sifus, I just realised that the guide (link above) is for I9100.

A few questions.

Is it possible to dual boot on I9100G as well?

Is Siyah Kernel 4.0 compatible with my G version.

Also, I'm on cm9 nightly 3rd august. After I flash cm9 nightly 6 august, can i delete the 3rd august nightly zip file from my phone?

I just flashed CM10, how do i configure my camera to store photos in my External SD card? there's no such option.

I just another problem with cm10. In settings> performance , no-frills cpu control and cpu tweaks, I set my max cpu speed as 300mhz and min speed as 150 mhz. then i locked my phone. when i unlocked it (after it went to deep sleep), it seems that the settings for cpu speed had been reset and my max speed is 1.2 ghz. why is this happening? This only happens AFTER i unlock my phone.

does it have something to do with the horsepower kernel i'm using? it worked perfectly on cm9 before this.

**EDIT: It seems that every time after I lock and unlock, my CPU speed settings are reset to min 300mhz and max 1.2ghz. Reflashed cm9 + horsepower kernel now and problem solved. was really close to jumping ship =/

Recently, I flashed CM10 to my I9100G. It seems that I'm unable to lock the CPU frequency. I checked the XDA forums and found this.
http://forum.xda-developers.com/showthread...774541&page=113

To solve it, codeworkx said,
adb root
adb shell rm /system/lib/hw/power.t1.so
adb reboot

Question 1: Does this step means using the terminal emulator?

Also, the user with this problem then said,
Had to remount /system as rw first, but it now runs

Question 2: What does he mean by remount?

Hope sifus can help Thanks!

Anyone can help?

What will happen if I flash Siyah kernel to my I9100G? I heard it's incompatible, but i'm curious to know what will happen.

oops. I won't try it then

hmm, when you guys say a ROM is smooth, is your cpu speed running on normal frequency? As in, you don't set the maximum or minimum frequency.

i see. but what about your cpu speed? Do you set it?

CM9 stable build is up! http://download.cyanogenmod.com/?device=i9100g
