Help/Support How do I resign a game app with my own apple developer id?

[00NewBie00 0 iPad Air 2 13.3]

Hi, 

I am new to IOS hacking. 

I have modified an ipa file by changing the binary ( within the app folder) after editing it with IDA. now i want to resign it with my apple developer id so i can install it on my non jailbroken ipad. 

Could anyone please suggest what are the correct steps needed to do so? I have tried to follow a few online tutorials for the same, however haven't been successful.  I am willing to compensate you for your time.

Sideloadly support apple dev account, you can untick "Use Asinette" option if your account is dev. Connect your device, drag and drop the ipa to sideloadly and it will sign for you

Hello,

You can use Sideloadly in this case.

 

Please note that Sideloadly only works for iOS devices and you mentioned ".so" which is for Androids.

Thank you for your quick response. I had edited the binary within the xxx.app folder and then repacked the app using winzip.  I had looked at a few tutorials which talked about removing the code signature and then resign the app using my own developer id which unfortunately didn't work.

@Rook  one more question . How can i allow installation  ( signing with my apple developer id) on the basis of selected UDID for an app? 

I have read that apple developer  allows some limited UDID numbers to be selected as test devices which can then be used? Can it work with sideloadly app?

Yes it can. Sideloadly will automatically register devices to your Apple ID when sideloading and paid Apple IDs are allowed up to 100.

I have a question which i have swept the net and not getting answer ? Can i modify the binary within the payload  ( generally goes by same name as application) if yes how to do it . I am not asking about hook files or tweaks.  Is there a way to directly modify the binary? like i do in android .so file and it works fine.. Can i do the same in IOS? 

I have added very cool features to a game i play but everything is in android by directly editing the il2cpp.so and i want to port it to IOS. Please suggest how can i do it ?

** The features added are not provided by IOS gods or any other hack sites.

What i have done so far is got the cracked ipa using crackerXi on my iphone and extracted it to my laptop and then edited the binary within the the payload.app using hex editor and used sideloadly to put it on my iphone. but the application crashes at times. so want to understand if i did something wrong?
