Summary

This repo contains the .mobileconfig files that you are able to download if you are an apple developer to help you debug your applications. The interesting part about all of these debug tools is the amount of data that can actually be gathered.

Some will say...well these are debug tools, of course you're going to be able to get more data than you normally should. The issue lives in the fact that the code to have this extensive logging is already written and embedded into the iOS kernel.

These .mobileconfig files are simply enumerators for services, and boolean switchers for entitlements that are already built into the iOS ecosystem.

Tools needed

1. brew install libimobiledevice
2. iPhone 6 or higher running iOS 11 and higher

How to install

1. after you download these .mobileconfig files you will need to send them to your phone. You can do this a few ways, airdrop one of these files to your phone and you will see a prompt asking to install
2. Go to Settings > General> VPN & Device Management and install the mobileconfig
3. When the mobileconfig is downloaded you will see it in your list of configurations

Gathering The Data

1. Depending on the .mobileconfig you installed, you may be asked to restart your device.
2. Actively use your device for about 15 minutes in order to gather enough data
3. Press volume up + volume down + power at the same time and then release. You will feel a buzz and possibly even take a screenshot (this is ok)
4. Wait another 10 minutes for the sysdiagnose to compress the data in your phone
5. Plugin your phone to your computer
6. If a trust dialogue comes up on the phone press trust and enter your passcode to trust if required
7. Open a terminal and type the following idevicecrashreport -e -k -d .

You should start to see an output that looks similar to this this.

9. Once complete you will see a lot of files, and among those file will be a directory called "DiagnosticLogs," open that directory
10. You will now see a directory called, "sysdiagnose," open that directory
11. Now you will see a compressed file that could be anyware from 50MB to 3+ GIGS, and should have a similar name to this: sysdiagnose_2021.10.19_03-55-36-0500_iPhone-OS_iPhone_19A404.tar.gz
12. Use a decompressor app if you are not using a Mac, or double click on this file if you are on a Mac, and it will extract the decompressed information.
