We all know that the LG Optimus L9 is not a powerful enough device on the market, so here I will show you how to overclock it to make it even faster. Its 1Ghz dual-core processor can be overclocked to 1.3Ghz quite easily. You can easily flash by using the guide below.


How to overclock LG Optimus L9 Steps:

1. Download and extract the Modules pack

2. Copy symsearch.ko and cpu_control.ko to /system/lib/modules

3. Change permissions to rw-r-r and owner to root-root

4. Open terminal and type (always load symsearch first)

  • su
  • insmod /system/lib/modules/symsearch.ko
  • insmod /system/lib/modules/cpu_control.ko

To get default freq and voltage table:

  • cat /proc/cpu_control/opp_table_default

Example for our cpu:

Id Freq Volt(mV)

  • 0 300 1025
  • 1 600 1200
  • 2 800 1325
  • 3 1000 1388

To get current freq and voltage table:

  • cat /proc/cpu_control/opp_table_current

To get current CPU & GPU frequency:

  • cat /proc/cpu_control/frequency_current

To change freq and voltage type or make a script to do it:

echo id frequency(Mhz) voltage(mV) > /proc/cpu_control/tweak_cpu, for example:

  • 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

You will have to try what is best for you.

Caution: Do this at your own risk, you are responsible for any damage not me.

This will work on all ICS omap4430 LG phones like p940 su640 su760 p760 p720 su870 with 3.0.21 kernel. This is not allowed to be flashed on any other device.

Well,here is the link:


Replacing yourimei with your LG Optimus Black’s actual imei (just numbers, nothing else), it’ll spit out a bunch of text including an address with all kdz firmware.
