im trying to update my 1000 from 3.90m33 to 5.50d3
from what ive read,updating from version prior to version 5 needs the ofw.

in the d3 ive just downloaded,there are 2 .pbp files.one is the eboot.pbp and the other one is 550.pbp.so do just need to copy these 2files into the update folder?

is there still a need to use the pandora batt?
