(adsbygoogle = window.adsbygoogle || []).push({}); If someone could point me in the direction of a solid step by step of the initial process for getting to 3.55 from a later OFW. I have a CECHA01 that i need to replace the heatsink and fan assembly to prevent a YLOD. last time i used it, it would freeze up trying to do anything but watch a movie, so i bought a new one and stopped using it till i could fix it. That was well over a year ago that i last turned it on. point is im looking at the parts i need on ebay and im thinking about just buying a completely new one, maybe with 3.55 or older on it.

if something like this has already been posted i apologize. i couldnt find anything that would help me with what im talking about.
