Great, let s brick that baby (since there s a devhook featuring 2.71 now).

Man this hack is frustrating... 12 times i ve tried and still no start of the downgrader... the exploit is indeed unstable 1/10 chance ? nhaa fewer odds than that imo

edit:
funny how the odds are
i tried 20 times on my sony 512MB (fresh formatted) MS and it didn t work
i try 1 time on my sandisk 1GB (not formatted) and it worked :P

Now remember to reupgrade to 2.00 and downgrade to 1.5 to get a clean 1.5 (the one made by the downgrader is OK for games but there has been reports of homebrews not working with the network functions fixed by an upgrade to 2 then downgrade to 1.5)

I keep trying this but it doesnt seem to work. When I do get a red screen it does nothing and my psp turns off. wtf Some help here please.

I haven't seen anything about this working for 2.70, does it make a difference?

I guess so... i upgraded my psp from 2.7 to 2.71 to downgrade to 1.5.

then i upgraded to 2.0 and downgraded properly with the official firmware.

pretty cumbersome but now with devhook i m free

All my later games work perfectly (tekken, itadaki street, valkyrie profile etc)

I got my 2.71 downgraded as well, it is awesome to play all the emus and homebrew. Incredible.

How does one upgrade fw 2.70 to 2.71 w/o the use of an actual UMD?

pretty simple. just download the 2.71 eboot file from www.psp-hacks.com.
then make a folder called "UPDATE" (gotta be all caps) in the GAME directory
and place it there. click on it and follow the steps to update as usual.

Just did the jump to 2.71 from 2.70 then the downgrade, didn't want to work on the first try for some reason but got it to work eventually, simple stuff

well I just pulled it of. I was shitting my pants though. Get me started where should I begin.
