Help/Support Cracking binaries for IDA

DXcool223 · July 29, 2018

ok so i used Uncryp11 to crack the binary and it worked but it crashed my game when I replaced the binary , the part I do not get is after I put my patches in the binary with ida , Do i need to sign it ? if so how, then does the cracked binary go inside a IPA (binary is bigger in IPA) or just put it back in /private/var/containers/Bundle, I am on 11.3.1

I looked up many tutorial but they are for older version of IOS 11, any help would be appreciated

You don't need to replace the binary. Load the binary to IDA and hack

There's no need for replacing a binary.

Just do code injection.

I was trying to do this with hex editor, so I take it that's the wrong way of doing it?, wanted to make it without a jailbreak but It does not matter, will try to code injection it if that's the best Way

For non Jailbroken do i just load the cracked binary and make changes to the original binary with hex editor, Thanks for the help!

For NJB you edit the binary with a hex editor & install it with Impactor.

It’s not wrong doing it. If you know the hex, then you can edit it. Keep the backup binary to somewhere safe if you mess up.

At the moment, you can’t crack the IPA on 11.3.1.
