Help/Support [SOLVED] Debugserver and IDA PRO error debugging

[GeTRoZ 10.7k iPhone 11 Pro 13.5]

Hi friends,

I am trying to learn hacking and I have a problem with debugserver on iDevice.

Environment:

• iPhone 6 Plus iOS 11.3.1 Jailbroked Unc0ver.
• MAC OS X
• IDA PRO 7.0
• Debugserver from iDevice

First I decrypted app from iDevice, downloaded to my MAC, deleted from iDevice and reinstalled decrypted version into my iDevice, after, I start de app and attach to debugserverfrom the  app PID: debugserver localhost:1337 pid_number. Debugserver started ok.

From IDA PRO 7.0 MAC, I load the app executable and select Remote iOS debugger. After, from Debugger->Process options... I set the full remote path to app executable into Application and Input file fields, leave empty Parameters field.

Select Start process and IDA popup error: The file can't be loaded by the debugger plugin. Please verify that the parameters are valid.

I need to set IP:port where debugserver is listening?

I am missing some steps or configuration?

Regards.

Hi friends,

In the end I solved the problem myself.

The problem was in the IDA PRO configuration of "Debugger-> Debugger options-> Set specifics options". I needed to uncheck the "Launch debugserver automatically" field so that in "Debugger-> Process options" it would give me the option to indicate the "ip:port" of "debugserver".

Thanks.
