Things You'll Need
Instructions
Separate your Sony battery into two halves by using the guitar pick. Very carefully, insert it in the division line between the two batteries and pry it open.
Locate chip S93C56 (this is the number printed on it). It's located on the leftmost side, in the bottom end. There are eight little pins surrounding the chip.
Ask someone to hold the soldering iron on the pins. Once the soldering becomes liquid, use an X-Acto knife with a sharp tip and put it underneath the fifth pin. Pop the pin up with the knife.
Attach the battery halves again by using waterproof glue. Now you have a Pandora battery and your EEPROM is erased.
