my ps3 ylod'd a few months back, and at the time i didn't actually believe that ylod existed. i thought it was a hoax made up by fanboys, but sadly it's real. after searching online to see if there was any way to fix this problem, i stumbled onto a youtube video posted by this site. after a few weeks i was pretty desperate to play some games, but i don't make enough money to buy a new system, and i don't want to lose all my account information. so i decided to buy the repair kit, and about a week or so later it arrived.
the repair took a lot longer than i expected, i've had poor experiences in the past with fixing things on my own, so i got my dad to help and really paid a lot of attention to the online guide. i'd say that the guide was perfect, my old system is functioning again, resurrected from the dead, and it feels great. thank you.
if this is your first time, be very patient, be careful with where you put the screws you take out, this process takes a lot more time than i expected but it worked and my systems back. if your careful and follow the guide you ought to be fine.
