If you have the patched kernel installed (the one which has monitor mode in wlan), try to type in terminal:

Code:

sudo gainroot

kernel-config show

If it shows errors, you need to install kernel-power-settings (if you need instructions, let me know, I will try to help)
If it shows you something like

Quote:

current kernel configuration:
current frequency: 950
supported frequencies: 125 250 500 550 600 700 750 805 850 900 950 1000 1100 1150
min. frequency: 125
max. frequency: 950
avoid frequencies: 125, 250
active frequencies: 0:30,90 500:30,360 550:33,400 600:38,430 700:45,430 750:45,430 805:48,430 850:48,500 900:54,50 950:54,500 1000:60,500 1100:72,520 1150:72,520
SmartReflex VDD1=0, VDD2=0
governor ondemand: ignore nice load= 1, up threshold= 75 sampling rate= 150000, powersave bias= 0

Then you should be able to overclock by:
1.

Code:

ls /usr/share/kernel-power-settings/

will show you list of available profiles
2. you can view their seetings by typing (example for profile named "ideal"):

Code:

more /usr/share/kernel-power-settings/ideal

There are lines:

Quote:

# minimum frequency to use
MINFREQ=500
# maximum frequency to use
MAXFREQ=850

which tell you which frequencies are available in a profile.
3. Optional: if none of build-in profiles satisfy you, you can create your own by:

Code:

sudo gainroot

cd /usr/share/kernel-power-settings

cp ideal myownprofile

leafpad myownprofile

And in leafpad edit lines with MINFREQ and MAXFREQ, for example if you want your device to operate in <250; 1150> frequencies, you should set MINFREQ=250 MAXFREQ=1150 and if you want your device to go on 1000 all the time, set MINFREQ=1000 and MAXFREQ=1000 also. Ignore other fields if you don't know what they mean. Also, instead of copying "ideal" in this step, you can copy "lv" or "ulv" or "xlv", they are supposed to use lower voltages, so that should mean longer battery life. But be careful with them, in some situations thay may turn of your phone (it's quite logical, lower voltage = less power for cpu, but you demand more from it, so it can just turn off due to lack of power, but honestly it never happened to me when using ulv config:P)
4. When you know which profile you want to use, type in terminal:

Code:

sudo gainroot

kernel-config load ideal

or replace word "ideal" with your chosen config name. Now command

Code:

kernel-config show

should show your edited settings.
5. After testing that these settings work for you and phone doesn't reboot automatically, you can set it to load these settings at start-up (if you won't do that, you will have to type in terminal "sudo kernel-config load ideal" everytime you reboot your phone). To do that, type:

Code:

sudo gainroot

rm -f /etc/default/kernel-power

ln -s /usr/share/kernel-power-settings/ideal /etc/default/kernel-power

You should change "ideal" to the name of your chosen profile. Now, it will load it at startup.

I hope I understood you correctly and helped you.
