hi all.
i have been looking on google on & off for a solution on the internet for the past year to disable the "power options" on the lock screen.

As of 20/12/11 (my birthday) my faithful cm7 rooted moto milestone was stolen from my vehicle.

Basically i need to find a way to disable the power options on all my android devices from the lock screen, so the only way to turn it off is by unlocking it and then turning it off.

I can glue in the battery, since i have acetone to remove the glue if i need to remove the batt in the future (only once did i need to remove my batt on my ph, and that was the time i put the sim in).

My skill level is in my opinion average, and basically i can get around most things with a good guide. the only thing i havnt been able to achive is to set up a personal wow server on my ubuntu server rack (wich is beside the point anyways).

Please help. If you know of an app or a way to do this, please explain it!
I really need a solution on this, because if another one of my phones gets stolen, i want to be able to find it (or blow it up so that it causes serious harm to the thief ;p).

Im pretty sure that the ph was turned off or the batt removed because the ph didnt respond when i sent commands to it, or when i tried to ring it...

thank you for your helpful and constructive reply.
Of course there is a way .But it's more of my error on my part .

Extract framework-res.apk from /sytem/framework folder
decompile it with apk manager
navigate to /res/drawable-hdpi
delete ic_lock_power_off.png
got /res/values/strings folder
delete power off string
open the /res/values/public
<public type="string" name="power_off" id="0x0104041a" />
<public type="drawable" name="ic_lock_power_off" id="0x01080530" />

Compile the framework-res.apk

extract android.policy.jar from /system/framework and decompile it with baksmali
and find
.method private createDialog()Landroid/app/AlertDialog
change the value from const/4 v9, 0x4 to const/4 v9, 0x3
recompile using smali .

copy and replace the files using root explorer or similar app or update.zip(preferred) and reboot
Rinse repeat for each android device

the power off option will be removed and the only way to do that will be using an app
to force a shutdown,using terminal or remove battery

There is 70 p.c Chance that the above method will fail and your phone will boot loop so keep a backup handy :D.

thanks karandpr!!
oh, btw, will this remove the power options completely or only during the lock screen?

it really amases me that something as logical as to remove the power off option during the lock screen needs to be difficult to achieve...
im sure that google should implement this, just in case of theft.
or an app would be nice as well.
thanks jerofld!!

im triing to find an e-mail to get in contact with the dev so that i can be %200 sure.
i need to be sure that it will work with ics, tablets and all android devices.

if it works, im going to buy it an all of my devices.

thanks again jerofld, thats a great little app.

maby in the future ill make a list of necessary apps that every device should have.
