IF YOU MESS UP YOUR PHONE BY DOING THIS I AM NOT RESPONSIBLE!!! CONTINUE AT YOUR OWN RISK!!!
** I did not make this icon set, and i can't give credit where credit is due because i do not know who did make it. I obtained it from Blackdroid's Ultimate Droid 7.8 mod for the Motorola Droid, but I am under the impression he didn't even make this... **
**** THIS IS FOR THE ROOTED 2.1 ERIS ONLY!!! ****
**** DO NOT ATTEMPT TO PUSH THIS TO MOTO DROID!!! ****
Download from here: http://billy.pl3x.net/android/eris_framework-res.apk
1) Download file from above
2) Rename file to "framework-res.apk" (without quotes)
3) Connect the phone to your computer and use ADB to push the file
Your phone will freeze up solid. DON'T PANIC!!! The phone will reboot itself after a few seconds. If it does not reboot after 60 seconds, feel free to pull the battery.adb shell mount -o rw,remount /dev/block/mtdblock3 /system
adb push framework-res.apk /system/framework/
After the reboot you will notice the battery icon has indeed changed.
