If your binary is thinned, the IDA file offset may be off. You can just use the hex bytes and search them on the file to find the offset.

Also make sure the binary is the cracked version. I just tried with an iOS binary and the offset pointed to by IDA is correct if you jump to it in a hex editor (I used HxD). Maybe IDA changes the endianness? But just make sure you bin is cracked. That's about it.
