[WARN] QA: use set_token instead of write_eprom!
i've seen some nice tutorials and tools around, but...
if you're going to flag your ps3 via linux, i'd recommend using set_token instead of write_eprom!
set_token will set the flag and write the token, if the token you specified is valid. if not, it won't write anything to the eprom (unlike write_eprom).
btw: another way to generate valid tokens ;)

compile together with f0f tools...
