Help/Support Help needed to resign an ipa

JustStarted001 · September 3, 2020

Hello,

I need help in resigning an app. Following is what i have done.

1. Extracted the Binary from the IPA

2. Changed the Binary using IDA and il2cpp converted and Hex Editor

3. Created a bundle id etc for developer account and updated the entitlement.plist

4. Removed existing code signature

5. Changed the mobile provisioning profile

6. Tried to sign the IPA using my developer account stuff but it fails. It says no identity found.

Can you please help? Where is it all going wrong?

I used the link below to learn about resigning and bought a developer account.

The ipa must be cracked / decrypted first before you doing any further steps. If you already have dev account then just use cydia impactor

Yes, The IPA is decrypted one. I used CrackerXi+ to get the decrypted IPA and then made changes to the binary. The question is how can i install this edited IPA on my device.

if you are jailbroken install the ipa with appcake and use appsync

It is not jail broken, that's why i want to sign it with my developer account stuff and use it on my device .

I have a jailbroken iphone 6 and non jail broken iPad air 2 . I retrieved the ipa file using the jail broken phone and after editing the binary ,i want to install it on the ipad.

In case you know how to sign an edited IPA file with developer credentials please let me know. The error which i get is Identity not found when i try to sign the IPA.

Codesign -f -s “What should i put here” --entitlements entitlements.plist Payload/MyApp.app

I have used information generated on my developer profile which i get from keychain app.
