Guide How to build Debugserver for any iOS (Mac only)!

How to build Debugsever binary for any iOSes on MAC OS X:

1. On Terminal

cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/7.0

(which iOS do you have, mine is iOS 9 so i need to cd to the 9.0 folder)

2. then

hdiutil attach ./DeveloperDiskImage.dmg

3. this will Mount DeveloperDiskImage.dmg, copy everything into a folder

4. Use iFunbox or SCP tool upload all files in DeveloperDiskImage.dmg to iphone /Developer (if you use xcode to debug on device before, you can skip this step)

5. find debugserver binary in /usr/bin in the files that you copied from the dmg before and copy it to Desktop or anywhere else (simple place).

6. cd to the folder that contains the debugserver and thin it to what Arch you want by any of these commands. (mine is arm64 so i'll use that)

lipo -thin armv7 /Developer/usr/bin/debugserver -output debugserver
lipo -thin armv7S /Developer/usr/bin/debugserver -output debugserver
lipo -thin arm64 /Developer/usr/bin/debugserver -output debugserver

7. next we need to sign the debugserver:

1st) make a new file in the same directory and name it

entitlements.plist

2nd) copy this code and paste it in the file.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/ PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>com.apple.springboard.debugapplications</key> <true/>
<key>run-unsigned-code</key>
<true/>
<key>get-task-allow</key>
<true/>
<key>task_for_pid-allow</key>
<true/>
</dict>
</plist>

3rd) Then sign it by this command.

codesign -s - --entitlements entitlements.plist -f debugserver

8. copy the debugserver to the iPhone by this command.

scp ./debugserver root@wifi-IP:/usr/bin/

(find the IP in ur iPhone's Settings/Wi-Fi then tap the little button near your Wi-Fi's name.)

We are done
