I have researched this for days and I honestly don't think there is a home fix for error 8002F1F9. With that said, I would like to find out more about what this error code means. Does it mean the bluetooth/wifi has problems or the bluray? or is it just a bad nand flash that just can't be fixed? I believe the bluetooth/wifi is part of the motherboard and cannot be replaced.
I have a 2nd hand ebay special with seal intact 160GB PS3 Slim that will not go past 41% using OFW 3.61 or any other OFW's. As a last resort NONE of the CFW's I tried will even load/start in high hopes I could see an XMB menu. The system can acess recovery menu when the PS3 HDD is formatted via PC but none of the 6 options in recovery do anything. New HDD in the PS3 does not help fix the problem.
A new observation I made tongiht is that if I pull the HDD out at EXACTLY 5% the update will continue all the way to 99% and then hang, while at 99% and inserting the HDD results in the 8002F1F9 error again. I could probably better understand what is going on if I knew what hardware issue is causing this. At 41% what is the PS3 checking to throw this error code? bear in mind this system has never been opened up so I highly doubt is a ribbon wire or tampering issue.
