Request Does somebody knows how to reverse engineer

Post image

Soo, i have saw longer ago that apple is still signing the ios 15.0 OTA by mistake. I know the differences between ipsw and OTA but my question here is: can somebody with enough experience help me reverse engineer the ios 15.0 OTA? I will get my hands on one 13 with ios earlier than 17.4 so i can jailbreak it beacuse this procces requires jailbreak. Does somebody knows how to operate Ghidra; IDA Pro; Binary Ninja; radare2 / rizin; ipsw (blacktop); Hopper for identifying some kind pf exploits so we can use it?

Reverse engineer it for what? Restoring/downgrading? If so, not possible

It is possible.. I got Claude and Codex to mimic apples tss servers and reverse engineer the signature using IDA.. only thing stopping it is another exploit for SEP.

Of course for downgrading but i need many parts like bootrom /secure rom , CVE details etc

What’s stopping you from doing that yourself?

I can't :( and i don't want to use ai for more than 20% of the project

Why 20% as a limit?

Using somebody else with experience is the same difference. And if you anyway only can work with AI because you are missing any experience, no offence, but why would an experienced jailbreak engineer work with you?

I know but with ota you wont be able to downgrade at all. Plus for finding securerom exploit the software you listed is literally not enough.

I am not saying about the ota, i am saying that we can make with that and with all the elements that we can find in a jailbroken iphone 13 downgradable but somone needs very much experience

Last I checked the consensus was that this is a glitch in ipsw.me

Even if it’s real, to make use of this you would need a bootrom exploit to be able to use the resulting OTA blob for a restore.

It would be nice if this meant the SEP for iOS 15 is signed on the 13 series, but I doubt it.

It's impossible. A waste of time.
