Okay, here's the skinny... My main PS3 is a CECHA01 running 3.55 kmeaw. For what it's worth, I also have a CECHB model sitting aside still on 3.50 OFW, that I rescued with a reflow... it'd just need a hard drive in it to be able to use it. Kmeaw has served me well for some time now. Which is why I'm surprised there hasn't been anything from the creator with regards to all these 4.** CFW's... I was half expecting and hoping to see some kind of release by now. But that being said, I know if I had a NOR-based ps3 with an e3 flasher or something, I'd have no issue with trying out all these new firmware(s) out there since I'd have a way of restoring from a brick situation. But like with the others, it seems all these hardware flashers either wouldn't work or would require extensive soldering on a NAND system that I lack the tools and know-how of how to do without screwing something up badly. So, I ask those of you on NAND-based PS3's particularly... are any of the current 4.** CFW's working well for you? Any bricks to report? Rogero if anyone seems to be really pushing forward with getting updated CFW out there.
