I've been trying to NOR write (CECHK), and I've been able to get "success..." a couple times, but it just locks up. My system is frozen, so there's a degree of progress, I'm led to believe, but it's been about 10 minutes now and nothing's happening. Both other times when i got the success message, it just froze up for over 5 minutes as well.
Can anyone help me out? All I have on my USB is the flsh.hex file, and i just wanna get some 'brew running on my ps3.
EDIT: Gonna check
this out now, from what i can tell the guy who retweeted this is big in the ps3 brew scene so I'd take it as legit, I'll edit again and say if it worked or not
Edit 2: Didn't end up working for me, from xmb or recovery, but your mileage may vary I suppose.
