[LG Optimus L9 P760, P765, P768, P769] csrow:
This is the instruction originally posted by kevev in the other thread. I am reposting it here for others to find it easier.

--------------------------------------------------------------

1.) Root your device.

2.) Download to your device "overclock.zip" from this thread:

3.) Install "AndroZip File Manager" from the Play store.

4.) Run AndroZip and browse to overclock.zip. (Probably /mnt/sdcard/Download .)

5.) tap on the file "overclock.zip" and select "Extract file here".

(A new directory named "overclock" is created)

6.) Install "ES File Explorer File Manager" from the Play store.

7.) Run ES File Explorer and press your "menu" button then select "settings".

8.) Change these settings:

Home Directory = /

Root settings --> Check all boxes

9.) Press the "back" button until the app exits.

10.) Run ES File Explorer again.

(Now your root partition "/" should be mounted with read/write permissions.

11.) Browse to the overclock directory. (Probably /mnt/sdcard/Download/overclock/ .)

12.) Long press on the cpu_control.ko file and a menu should open. Select "copy".

13.) Browse to the /system/lib/modules/ directory .

14.) Press "menu" button and select "Operations" then select "Paste" .

15.) Long press on the cpu_control.ko file and a menu should open. Select "Properties".

16.) Press "Change" and check the boxes like this:

User: read write

Group: read

Other: read

17.) Perform steps 12-17 on the symsearch.ko file which is also in the overclock directory.

18.) Install "Rom Toolbox Lite" from the Play store.

19.) Run ROM Toolbox Lite and select "Scripter".

20.) Press the "+" symbol in the top right corner and select "Create" to add the overclock script.

21.) Name it "overclock" or whaterver you wish.

22.) In the "Commands:" field enter this:

insmod /system/lib/modules/symsearch.ko

insmod /system/lib/modules/cpu_control.ko

echo 0 300 980 > /proc/cpu_control/tweak_cpu

echo 1 600 1200 > /proc/cpu_control/tweak_cpu

echo 2 800 1300 > /proc/cpu_control/tweak_cpu

echo 3 1200 1370 > /proc/cpu_control/tweak_cpu

23.) Your phone will overclock to 1.2Ghz.

If you wish to overclock higer you can try changing 1200 in the last line to 1300 for 1.3Ghz.

24.) Press the floppy disk in the top right corner to save the script.

25.) Press the overclock script and a menu will open. Select "Run Script".

If everything worked you should see an "exit valut:0" message.

If you run the script again you will see the same value but with a warning message.

This is normal since the modules are already loaded.

26.) You can load a cpu monitoring app to see if the overclocking works or just create another script that displays cpu clock info.

Here is the command for that script:

cat /proc/cpu_control/opp_table_current

27.) After making sure your device is stable you can have the overclock script run automatically at boot.

Press the "overclock" script and a menu will open.

Press "Set at boot"

Reboot the device and you will see a notification that the script ran in the notification area of the device at top.
