Can't dump apps - iOS 11.3

[ftitreefly]

• iOS 11.3
• Any App failed
• Clutch -d YouTube --verbose

Clutch -i works, and shows app list.

Attempting to dump any app, such as YouTube, it always fails:

• Can't execute task_for_pid! Do you have the right permissions/entitlements?
• Could not obtain mach port, either the process is dead (codesign error?) or entitlements were not properly signed!

tfp0 patch!

[truewebber]

@ftitreefly, hey!

I'm not good in software dev, especially in jailbreak. So, i found this https://www.theiphonewiki.com/wiki/Tfp0_patch#Example_code, build and sign example code for my iOS 11 device and got in result KERN_FAILURE.

Do you or anyone else know what does it mean? I guess it means that Electra(1.0.4 in my case) don't provide working task_for_pid, right?
