TrollDecryptJB, it allows install app require higher iOS and then decrypt it. I had some issue on lldb (the lldb script need to be pause before it crash and fully loaded fairplay)

So basically, it’s a TrollDecrypt

But it can help you download iOS app that require higher iOS minimum in Appstore and then decrypt it.

Did it actually work?

Bascially yes, at some point. On the source code I publish, sometimes it works, sometimes don’t, I’ll explain the method details. If you want to contribute to it then the PR is on top of the page! You’re welcome!

How did the decrypt ‘works’?

So on a random day, DuyTran told me that he saw a reddit post that someone said an online telegram bot can decrypt iOS that require minimum is iOS 26, I also remember myself i used to install higher iOS app on my iPhone with appstoretroller (thanks to Mineek and Nathan) to install app.

The author of the post seems not sharing the method but luckily DuyTran found it out. He started lldb and attach –waitfor it, run until right before the app loaded fully FairPlay (LC_ENCRYPTION_INFO/LC_ENCRYPTION_INFO64) and hit abort(). From that we can decrypt the app without need it fully running/loaded, just make sure the app is loaded at least 0x4000 pages right after run and then decrypt the FairPlay and it’s done.
