PSP Downgrader - Downdate Final Version For v2.50/v2.60 PSP Firmware

[phazi]

i think some one asked this but why dosnt it work and will there ever be a way for a new psp that comes with 2.6 to downgrade or no chance at all

"- Removed the logs, they could cause problems with people with 32 MB memsticks."


I'm not sure what that means, but I successfully used the beta version of the downgrader, so my question is, what kind of problems will the logs cause to 32mb sticks? Does it cause problems with the memory stick or with the psp? I should have just waited for the final release cause I'm all paranoid now...

Syphon Filter UMD works great with Devhook. It'll be hard to find a UMD that doesn't.

Kramer: It does write (1KB) logs to the memory stick whenever an operation is executed.. it generates quite a few, but much less than any memory stick should have free. The main deal is that it works perfectly.

Awesome! Thanks heaps, sounds like a very well made app

Worked beautifully. Absolutely no problems.

I started with a 1.50 PSP, made my own 1.50 dump, then updated to 2.60. Then downgraded to 1.50. Quite a marvelous feat.

Now this got me thinking... Anyone who has a 1.0 and tried the 'downgrader' for that(the one that only works on the system it made the dump from)... I wonder if that can be used in conjunction with this or the 2.0 downgrader.

I read that people where downgrading their factory 2.6 psp successfully to 1.5. Anyone on here try? I bought mine used and I am assuming it was 2.6 factory. I dont think there is a way to tell

Yes you can downgrade.
You pretty much have to update first if you had anything below a 2.5 to use this anyway.

As long as you didn't buy a 2.6 version psp your good to go.

One of my psps is a 2.01, I missed downgrading last time by one small update so I have been looking forward to this.
Odd that the device hook almost coincided with the release of this, someone loves us.

The password listed on the front page didn't work for me btw, I'm not bothered because I have the beta.
Just a fyi, is it because of the caps?

I'm no Charles Babbage (That guy would have rocked the PSP scene with a Homebrew Abbicus app).
But I believe it's the raw files that make up the 1.5 update... It's a 'dump' of the update and what's in it... Sound alright?

cheers
