[T-Mobile, Samsung Galaxy SIII] almighty bob:
This mod fixes the cell standby values in the power profile for stock roms. this will be apparent when your cell radio is off (wifi is on, or background data is off), the cell standby will report higher than normal usage).

CM 10 is based off of the sgs2 and uses it's power profile values (at least it did last time I checked) so you don't need to flash this. most custom roms include this fix so you don't need it.

Installation:

Reboot to recovery

Make a backup of your phone (I'm not responsible for bricks)

Flash the zip file

Reboot

Files:

CWM-ModStandby.1.0.zip (based on the stock UVALEM framework res apk)

CWM-ModStandby.2.0.zip (based on the stock UVALH2 framework res apk)

CWM-ModStandby.3.0.zip (based on the stock UVALJ4 framework res apk)

if you don't want to use the cwm update zip or have a stock build other than one of the ones listed above and / or want to apply the fix yourself, you can do that bydoing the following the manual update steps:

Manual Update:

download this apktool set and extract it somewhere simple like c:\apktools.

copy your framework.res.apk from your /system/framework folder to your computer to the c:\apktools folder

rename apktool.jar.1.4.2 apktool.jar

open a command window and run the following commands

java -jar apktool.jar if framework-res.apk

java -jar apktool.jar d framework-res.apk

browse the decompiled folder structure to your res/xml folder and locate your power_profile.xml file

edit it in notepad/notepad++

locate the device/array[name=radio.on]/value node (there will be two of these)

change the value from 34, to 3.4

save

rename apktool.jar back to apktool.jar.1.4.2 and rename apktool.jar.1.4.3 to apktool.jar

back in the command window recompile the framework.res.apk by issuing the command:

java -jar apktool.jar b framework-res (this will likely display a lot of warnings about "no default translation yatta, yatta" which is fine)

this will re-compile your edited power_profile.xml file and place it in your c:\apktools\framework-res\dist folder (assuming you put things in this default folder)

open this file with winrar or 7zip (DO NOT EXTRACT IT) and pull out the compile the power_profile.xml file

open your original framework-res.apk (AGAIN, DO NOT EXTRACT) with winrar or 7zip, browse to res/xml, and drag the newly compiled power_profile.xml file (the one that you just pulled out of the newly compiled framework-res.apk. you can't use the one you just compiled as its missing all the important files that we didn't really extract) over on top of the existing power_profile.xml file inside the winrar window. this will replace the existing erred compiled power profile with the fixed one, and winrar will re-save it.

now reboot to recovery, adb shell, mount system, rename your existing framework-res.apk, copy this modified one over, then reboot. If you can't adb you can always take one of the cwm files I've posted, open it in winrar (open, don't extract it) browse to the /system/framework folder, and drag your new framework-res.apk over the top of the existing file and let winrar update the zip file. then flash that updated file on your phone (remembering to make a nandroid first just in case).

If you have another build that you'd like to include in a flashable form, send me your framework-res apk and I'll mod it and upload it up here.
