[Motorola Droid RAZR] BytecodeMe:
Okay guys, I made some kernel tweaks that work on any ROM, and on the ROMs I have tried, improve battery life/performance.

THE BATTERY SAVER SCRIPT WILL NOT IMPROVE QUADRANT SCORES!

THIS SCRIPT WILL BE UPDATED FREQUENTLY!

Last update 7/11

Latest update notes: Focused more on battery life.

Battery stats on Liquid Smooth 1.5 with script:

Prerequisites:

Have root access

An app that can run scripts on boot, like Script Manger, located here:

https://play.google....ptmanager&hl=en

INSTRUCTIONS:

If using Script Manager:

1. Navigate to file.

2.Open as Script/Executable.

3.Set it to run at boot and as SU.

4.Save

5. Reboot.

If using ROM Toolbox:

1. Select "Scripter"

2.Select new script

3. Copy and paste script into Scripter

4. Select "At Boot"

5. Reboot

Make it Last script:

IF THESE SCRIPTS DON'T WORK, USE THIS ONE.

Find them HERE

STEP 1. Under File, select DOWNLOAD.

STEP 2. Find a way to get it to your phone,make sure it's not opened in any text editors, until it's on your phone.

STEP 3. Follow other instructions

Latest update notes: enabled ZRAM(compressed RAM), loads SIO I/O if available, also loads the hotplugx governor and SIO on boot. Ups read and write speeds all around, file system speedups, enables multi threading, tweaks to the hotplug and hotplugx governor, and more. You might get random reboots using this script, you might only get a coupke and then they will stop or they'll never stop. Inform me if you consistent random reboots.

GET THE SIO I/O SCHEDULER AND THE HOTPLUGX GOVERNOR HERE!

I HIGHLY RECOMMEND THEM FOR PERFORMANCE!

You will definitely see a boost in performance when running the following script.

For this to work, either run this code at boot with an app like ROM Toolbox.

Or run the attached file at boot with an app like Script Manager.
