and those 6.37 have to update to 6.38 in order to downgrade :3

have you tried it yourself?

haha nope, but from what I read from other ppl's comment ehe
for this downgrader, have to be on ofw6.38, i think 6.37 won't work.
with motherboard 06g and below, can downgrade to 6.20.
as for 07/09g, they're advised to downgrade to 6.35.

I've been reading new comments tho

do you have a psp go? if so make sure you are using the psp go ofw not psp 1000/2000/3000

also would suggest you go to 6.20 as the lcfw for 6.20 have a perma patch meaning you don't need to keep reloading the lcfw.
