1 - roll back
Sorry I'm new.
I have a two part question.
1. I have a psp 1000 with firmware 5.50 and want to upgrade to custom. Is it possible to go back to the official sony firmware once I do so? If so, is it easy or hard?
2. Do you think all firmware is hackable?
Sorry for the newb questions, but these are important if I want to upgrade. Thanks. |
