So I just picked up this PSP used and was expecting to hack it but found a 4gb stick preloaded with some games! Just curious since as the title of the post states I'm running 5.50 gen-d2 should I upgrade to what seems to be the most reliable at 6.20? I'm mainly asking to make sure that I won't cause more harm trying to use a stock firmware to upgrade a custom firmware.
Thanks for the help
