recently our friend mathieulh has released a video with a retail PS3 he QA flagged.

of course, he won't share how to do it

but... its pretty easy :p

requirements:
grafs kernel, ps3dm-utils and linux_hv_scripts

to patch your DM you have to run dmpatch.sh (skip if you're on gitbrew fw)

read QA flag:

    

ps3dm_um /dev/ps3dmproxy read_eprom 0x48C0A

it should return 0xFF on retail ps3.
just set it to 0x00

write QA flag: <- on your own risk!

    

ps3dm_um /dev/ps3dmproxy write_eprom 0x48C0A 0x00



OR



ps3dm_um /dev/ps3dmproxy write_eprom 0x48C0A 0xFF

its a very mighty tool. you can also enable product mode and other things.

I've already posted here:

did you even read this thread? look at it even?

Yes, and its exactly the same information I posted in the other thread.

Anyway who cares.... the more publicity this gets the better.

so your post said how to set QA flag on a ps3? i didnt see that part on your thread.

Its not my thread, I posted it in the thread. :\
But I guess this is awesome enough that it warrants a new thread to be made.

well no wonder i didnt see it :p :black:

I think I need an Aspirin. :p
