Isn't this describing the format for the '2gmIogol' file?

I've read somewhere in this section that iPSWTool.app will handle the image conversion to let you put your own customs Boot and Recovery/DFU images.

I don't know if iBootIm is always a "2mgIogol".. anyway, except I don't clearly see any reference to "2gmIogol" on that page, everything else resembles those unencrypted .img2 files.. well, it looks to me at least (but I'm *very* far from being an expert )

However I don't have access to a windows box to install 010 on, so I can't even try that template, and I don't entirely understand it.

So if someone understands it and is willing to put it in comprensibile terms (even just a method, something) for me I could try to figure out a way to actually convert an image to img2 (sharing the code under MIT)

PS: to me it looks like chronicle's tool will allow people to choose from a pool of pre-made img2 files.. but I may have missed the right post

Great, thank you! I'll dig into it

WinPwn is set to have a custom logo encoder so you can wait for that.

I don't have a windows box

It's not clear to me if ipswtool will feature it or not, beside the bending admin I havent been able to find any evidence that it will

openssl enc -d -in yourpic.jpg -out logo.img2 -aes-128-cbc -K 345A2D6C5050D058780DA431F0710E14 -iv 0

That won't work. To begin with it's "openssl enc -e ...". "-d" is decrypt.
Second, that will encrypt only the payload, you still need the headers (ie full container vs just data).

I wrote a "decrypter" as proof of concept. It can be found at http://pasteb1n.ca/977711 (replace 1 for i). It takes a IMG2 file and saves it as PNG.
openssl, zlib and libpng are needed to compile it.
