General :: How To Reboot Instead Of Battery Animation

I am a budding developer in Android platform..while I have developed some small tools on Android, the project which I am on now demands a unique requirement.. I want to keep the phone running my application always on and must boot up automatically when a charger cable is plugged in. I know this question has been asked many times and there are many threads for this. But to no real answers..

I had managed to do the auto boot on power insert by editing a script called "battery-charging" in /system/bin in a version of Android I used earlier.

I managed to get the same effect in another device (a Samsung phone) by editing /system/bin/chargemon

Forum rule says I cannot post the external link ... this is how I did achieve what I wanted earlier...

Code:

echo "echo skipping chargemon" > chargemon.script
adb pull /system/bin/chargemon chargemon.backup
adb push chargemon.script /sqlite_stmt_journals
adb shell
$ cd /sqlite_stmt_journals
$ su
# mount -o remount,rw /dev/block/mtdblock0 /system
# cat chargemon.script > /system/bin/chargemon
# chmod 755 /system/bin/chargemon
# reboot -p
'
But I have been handed over a phone running Android 2.2.1 where I could not find both "chargemon" or any file regarding battery charging status in the /system/bin or in any other path.

I just have to edit the script which executes the battery charging animation graphics when the phone is switched off but is powered up to allow the phone to reboot.

which file to edit to make the phone reboot instead of just showing battery being charged..
