Yep, the above steps are for de-odexed ROMs, but you may still be able to disassemble if you pull the jar and odex and run baksmali on android.policy.odex. If you get errors trying that then pull everything from the /system/framework folder and try it again


Annoyingly, i've just noticed that once the phone goes into a 'deep sleep', the volume buttons don't always wake it. Sometimes they'll work after a double press sometimes it needs to be the power button :-\

I need some help if you would be so kind.
I am trying to follow your instructions but i am only getting as far as pulling the files.
I am on a rooted stock odexed rom and when i try to run
baksmali.jar -x android.policy.odex -o classout
It seems to go through (no error) but i dont get a classout folder in my adbtools folder or anywhere else as far as i can tell.

Am i doing it all wrong?

Try setting /sys/keyboard/vol_wakeup to 1 instead of 0...along with instructions in OP....

Thank you so much!

Sorry if this is a weird question but I am interested in disabling this feature in the ROM I'm on, it's the only feature I don't care for. On a galaxy s2 if it matters. Can I simply reverse the processes if this was the process used to initiate volume wake?

    I got so used to using the volume rocker to wake my DHD and show the lockscreen instead of the power button that i decided to try and add the same functionality to the OneX. The only caveat with this is that sometimes the volume slider shows up when it wakes, but i can live with that :)

    Hopefully, in time, the ROM devs will add this in by default or as an option. Until then it'll require these manual mods...


    Don't try the following if you're unsure what you're doing as you could potentially break the ROM if not done correctly. I recommend backing up first in Clockwork Recovery in case things go wrong.
    I accept no responsibility for any issues encountered making these changes!



    Requirements
    Rooted phone
    Android-SDK
    baksmali/smali from here

    Step 1 - Update android.policy.jar

    1. Do the following to get the android.policy.jar from your phone and disassemble it
    Code: 
    adb pull /system/framework/android.policy.jar .
baksmali -x android.policy.jar -o classout
    2. Open the following file in a text editor
    Code: 
    classout/com/android/internal/policy/impl/KeyguardViewMediator.smali
    3. Find the method "isWakeKeyWhenKeyguardShowing(IZ)Z"
    4. At the bottom of the method, there's a switch statement. Remove the following 2 lines from it:
    Code: 
            0x18 -> :sswitch_5
        0x19 -> :sswitch_5
    5. Save the file and close it.
    6. Run the following commmand to re-assemble classes.dex
    Code: 
    smali classout -o classes.dex
    7. Drag the classes.dex into the android.policy.jar file to update the file in there.
    8. Push the updated android.policy.jar back to the phone
    Code: 
    adb push android.policy.jar /sdcard/
adb shell
su
sysrw
cp /sdcard/android.policy.jar /system/framework/
chmod 644 /system/framework/android.policy.jar


    Step 2 - Update Generic.kl

    1. Pull the file from your phone
    Code: 
    adb pull /system/usr/keylayout/Generic.kl
    2. Open it in a text editor and change the lines
    Code: 
    key 114   VOLUME_DOWN
key 115   VOLUME_UP
    to
    Code: 
    key 114   VOLUME_DOWN	WAKE_DROPPED
key 115   VOLUME_UP	WAKE_DROPPED
    3. Push the file back to your phone
    Code: 
    adb push Generic.kl /sdcard/
adb shell
su
sysrw
cp /sdcard/Generic.kl /system/usr/keylayout/
chmod 644 /system/usr/keylayout/Generic.kl

    (of course, you could also make those changes to the file directly using a root file explorer app and text editor.)


    Step 3
    Reboot the phone.

    Note: The first time it boots after changing android.policy.jar, there'll be an 'Android is upgrading' dialog. This is normal and it won't happen on subsequent reboots.

    Am I correct that this mod will work only on deodexed android.policy.jar ?

    Would it in theory be possible to use the home button to wake the phone or is that impossible because the buttons don't work when the screen is off?
    I have wake on TP on my Desire now.
    Click to expand...
    Click to collapse

    Not possible as the buttons don't work when the screen is off.

    And when the phone goes to deep sleep mode, volume button to wake it not really works (tried both on odex and deodex ROMs).
