iPhone PNG normaliser?

[AdrianK]

I have an encrypted root FS DMG for iOS 4.3.2, and I'd like to be able to access some of the images, but they have modified headers. There are a million and one tools out there but none of them seem to work, not fully anyway, I keep getting between a 1/3 and 3/4 of the image, very rarely the whole thing.

Has anyone been able to "normalise" any images from a recent iOS dump?

Well, I've narrowed down the issue a bit. It appears that PNGs can't be normalised from 3.2 onwards (3.1.3 is fine), *unless* they're quite small (<~300*300) It looks like there isn't an updated method out anywhere, shame

I'm on a Mac and I use this. Not sure if this is what you're referring to.

Yeah, that's the tool. Problem is it's using the same method as all other normalisers, does not work with PNGs in FW versions 3.2 and up

I'm on 4.3.2 and it works fine. I noticed that the droplet and the .png have to be in the same folder for it to work. I just use it on my desktop, then toss the droplet back into my applications folder when done.
