Installation Instructions:

Here's a step by step instruction to install this kernel:

**************** Jelly Bean ****************

[ CFS ] (Ultimate Edition - should work with most phones but NOT GUARANTEED!)

The File ==> Hercules kernel (1.73 GHz, L2 speed up to 1.56 GHz, GPU 3D @ 320 MHz, GPU 2D @ 220 MHz, CleanCache Enabled) <==

**************** ICE CREAM SANDWICH ****************

[ CFS ] (Ultimate Edition - should work with most phones but NOT GUARANTEED!)

The File ==> Hercules kernel (1.73 GHz, L2 speed up to 1.56 GHz, GPU 3D @ 320 MHz, GPU 2D @ 220 MHz, CleanCache Enabled) <==

**************** GINGERBREAD ****************

[ CFS ] (Mainline Edition - should work with ALL phones!)

The File ==> Hercules kernel (1.73 GHz, L2 speed up to 1.56 GHz) <==

[ CFS ] (Ultimate Edition - should work with most phones but NOT GUARANTEED!)

The File ==> My Global VDD_TABLE for under volt patch <==

Optional Under voltage:

[ to over volt ALL frequencies by 25000 uv (microvolts) ]
echo "+25000" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels
[ to under volt ALL frequencies by 25000 uv (microvolts) ]
echo "-25000" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

[ to set a specific frequency (ie 1.18 GHz)
with a specific voltage (ie 1.0875 volts) ]
echo "1188000 1087500" > /sys/devices/system/cpu/cpufreq/vdd_table/vdd_levels

echo 192000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo 1188000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

echo 1 > /sys/devices/system/cpu/cpu1/cpufreq/online
echo 192000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq
echo 1188000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq

1. download the above file (via phone directly or to a PC)

2. copy the downloaded zip file to /sdcard/download/

3. Open ROM Manager and select "Reboot into Recovery" and select "OK"

4. Once in recovery, select "wipe cache partition", select "Yes", then select "advanced", then select "Wipe Dalvik Cache", then select "Yes" again. Once finished, click the back button to go back to the main recovery menu. On that menu, select "Install Zip From SDCad", then select "Choose zip from SDCard", then go to /sdcard/download and select the downloaded zip file and let it run its script.

5. Once the script is done, select "reboot system now"

Note: After FLASHING, the first reboot may take longer than usual, please be patient... After the first reboot, it may lag during initial load (let everything finish loading). Once everything is loaded and phone is ready for use, reboot the phone a 2nd time and the lag will be gone and everything should be silky smooth...
