I want to jailbreak my iPhone 4s, but I cannot sign the Phoenix5b.ipa app, the normal way I would. I sign using iOS App Signer, and I get an error like this in Xcode: Unable to install Phoenix5bSigned.ipa. I have tried installing through Apple Configurator 2, and Finder (I’m on Big Sur) and I have not had any success.
I have previously used the same method on my iPad 3. That works. Any help appreciated.
