Help/Support IDA / gdbserver error 193

[xbhuntx777 0 11]

I just started to look into mods and such recently, so I am very new to this. I have iFunbox, IDA 64-bit, and Gdb/Gdbserver. I know you take the app from the device and transfer it onto the computer through iFunbox. Then you take the app, binary file (if i'm not mistaken), and open it in IDA. Normally all of the tutorials I have seen, the strings and code are pretty straight forward and understandable. Most of the games I have been trying, the stings are a bunch of symbols and it's nearly impossible to know what values to change.

 

So I tried Gdbserver to make a remote host to debug it, but when I click debug it tells me on IDA " The file can't be loaded by the debugger plugin. Please verify that the parameters are valid."   I do not have any parameters set. And at the same time on gdbserver it says listening, remote debugging from host, and then error creating process with the game file and (error 193).

 

My question is, Is there a program or something that I am missing? or Is there another way to go about dealing with code that has nothing but symbols in it? I am trying to learn, and there is very little info on how to do this, but it interests me. I'd appreciate any help or a fix, ty.

Greetings,

 

You should install GNU Debugger (GDB) from cydia.radare.org repo.

 

Then SSH into your idevice using PuTTY and run 'gdb'.
