Things you need:
-decrypted system_plugin_fg.rco
-Rco Editor v1.15c
Pretty basic...
1) Open up the decrypted system_plugin_fg.rco.
2) Click on the anim_data tab.
3) Scroll down to anim_battery_charging @ 0x1B20
4) You can see four [0x906] Set Object Alpha's. Two of them have "1" at the fifth line and two of them have a "0" at the fifth line.
5) Edit the two Set Object Alpha's with "0" on the fifth line change the "0" and the fifth line to "1" like the first two Set Object Alpha's by simply double clicking on the "0" or highlight them and click change.
6) It generates a back up file incase you do something wrong. Just delete the *bak extensions at the end.
Here's a screenshot:
