recently our friend mathieulh has released a video with a retail PS3 he QA flagged.
[ame=http://www.youtube.com/watch?v=TzQLseA_ynU]YouTube - QA Flagged ! Read Description[/ame]
of course, he won't share how to do it
but... its pretty easy
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:
it should return 0xFF on retail ps3.Code:ps3dm_um /dev/ps3dmproxy read_eprom 0x48C0A
just set it to 0x00
write QA flag: <- on your own risk!
its a very mighty tool. you can also enable product mode and other things.Code:ps3dm_um /dev/ps3dmproxy write_eprom 0x48C0A 0x00 OR ps3dm_um /dev/ps3dmproxy write_eprom 0x48C0A 0xFF
