Well when i took my PS3 HDD and plugged it into my Pc internaly, then when i put the same HDD in my PS3 it would not start and said Connect System software via Storage device and press Select and start, and i couldnt do anything else, and the PS3 was running on 3.3 before.
So i just did a quick tut in case anyone else did that trying to mod the patch
