Nothing. The root of the PSP is your memory stick drive.
So... if it were H: you'd transfer the files to H:/

That's right but step 5 should be above step 3.
After you overwrite the PSP folder with the one from the downgrade pack you copy UPDATE.PBP into the UPDATE folder.

I was just wondering whether this makes the 3.03 downgrade and the 2.80 downgrade obsolete. As in would you just upgrade ANY psp (Below 3.50) to 3.50 than downgrade from there? Or do you recommend upgrading to the closest version of your firmware eg. 2.70 to 2.8 or 2.9 to 3.03 than downgrading. Or there is absolutely no difference. I'm asking this as I'm looking at doing a few friends psp's but there all on different versions so If I could learn just this method that would be great. Thanks in advance.

I see you can also do a 2.71 downgrade so my example 2.70 to 2.8 aint quite right, but you get me. I think..
Nah it doesn't make those obsolete. Reason being is because you need Lumines to use it. If someone is on 2.71 and doesn't have Lumines, then they will want to use the 2.71 downgrader.
If you have Lumines, then I'd just suggest upgrading them all to 3.50 and then downgrade to 1.5.
What do you mean by that?

But I was committed after that birthday party...
I believe what he means is if he can leave it on 3.50HEN and just run homebrew 'n' such from that, without downgrading. I believe if you completely turn off your PSP and turn it back on then the HEN is gone, correct x3?
Yeah that's right. But 3.50 HEN can only run the downgrader plus some sample applications included in the zip... nothing else.

Well you don't need to know the motherboard version as the downgrader will automatically detect it.
No if your PSP bricks there is no way to fix it other than getting a modchip. But 99% of the time the downgrader will be successful. You can't rule out hardware issues though.

it means that some times when flashing there would be a hardware crashdown, both temporary or permanently, but the chances is REALLY little. i screwed up my psp this morning and flash from 1.5 to 3.40OE-A between like ten times and my psp is still fine. so it's almost impossible to have a hardware crashdown.
relax~.
read this thread at the bottom again:
just follow the steps SLOWLY, plug your ac on your psp and you will be fine. after downgrading to 1.5 take your UMD out just in case the game auto starts and auto updates again.(take it out after finishing downgrading and before you open your psp again.)
