You need to have custom firmware to run pandora's battery

Do you mean i need to have custom firmware installed before i do start the pandora's battery thing?Can you give me some examples of custom firmware?Do i have to reformat my mem stick again for custom firmware?I thought i had to downgrade to v1.50 before i can install custom firmware. Am i right or wrong?Help?

Calm down, it ain 20 Q.

You have to downgrade to 1.50, from there you can use pandora BUT it is suggested that you update to at least 3.40 OE-A custom firmware before you do stuff.
