Hello, I would like a step by step guide to downgrade a 2.8 to 2.71 and then to 1.5
Thanks

There are instructions on 0okm's blog for the 2.80 to 2.71 downgrade with the release:

If you follow them perfectly then you will get to 2.71.
However, some people have found them hard to follow, and ended up bricking their PSP.
So an Easy Downgrader was made with even easier to follow instructions:

Some general advice:
- read all instructions VERY carefully before starting
- have your PSP fully charged and plug in the power cable

When you get to 2.71, post a reply and if you still need instructions for that part I'll see what I can do.

THANKS A LOT

Does this mean that you got it to work?
If you haven't yet; there's an improved downgrader all the way down to 2.80 here: http://www.psp-spot.com/forums/280-generic...der-t33090.html

erm does the easy downgrader works for 2.60 or do i have to upgrade to 2.8 THEN downgrade to 1.5?

anyone has links to any tutorial for non ta82 board downgrade? i'm lost

You have to upgrade to 2.80 then downgrade to 1.50.

The Easy Downgrader for 2.80 works for non TA-082 boards as well; just skip the "TA082 IdStorage Changer" stage.

yeah i used the improved downgrader it worked fine can i play metal gear solid on my 1.5 psp now and does it still maintain the feautres of the 2.8
