I jailbroken my iPhone 4s with iOS 8.2 and tried to ran debugserver, then I met this error:
# debugserver *:9988 /var/mobile/Containers/Bundle/Application/P-A-T-H/to.app/Binary
error: failed to launch process debugserver: Security
Google doesn’t help.
Just because, the App I’m trying to crack is an In-House app, not from AppStore, I have to ran it after installation and choose to trust the developer.
