I was updating my PS3 slim software to 3.41. I finished the download then installed it, but the INSTALL stopped at 99%. I got frustrated after about an hour that it was stuck, and turned it off holding the power button for 10 seconds. When I turn it back on, it goes straight back to the install and gets stuck on 99% again. So I tried to leave it on to see if it would fix itself, and it’s been on for 2 days and still stuck on 99%. I’ve already talked to SONY and they said I could send it in for $150, but I dont want to pay them 150$ for something that i can do at home. What can I do to fix it?
