Props to the 5.50 psardumper :) Switching my psp to UMD for USB connection and taking the data.bin and param.sfo to make an eboot.pbp i was able to use the 5.50 psardumper to extract and decrypt the files of the firmware :D
Then good ol resurskilinski in time machine and voila, we now have the rcos editable :D
First quick look...vshmain compare of 5.50 to 5.55 only has a change at 11db9 and 43a60 00 to 05
