A few hours ago, we reported the news that
a working PSP Downgrader was out and about on the
internet. Now we've got a step-by-step tutorial for the downgrade (with pictures!) from
TUAW's own C.K. Sample, III, on all the steps needed to downgrade from the 2.0
update to the 1.5 revision of the PSP firmware. Check out the
report currently up on hack a day for more, including a confirmation that upgrading back to 2.0 (and reverting once
more to 1.5) is also a reality.
Of course, we have to warn you again that not following directions can make your expensive Sony portable into a very
sad little paperweight, so be sure to watch your step should you decide to proceed any further.
[Thanks, C.K.]
