Required Knowledge

Before starting you will need some terminology and information. For the moment only the Windows install method requires DMG files which holds the debugger needed to activate JIT (just in time).

This tutorial is using DolphiniOS as a reference but it also works on other apps other than DolphiniOS, like PPSSPP and UTM. The tutorial gets revised over time and might even fix some install issues.

We have gotten a lot of results from people trying it out and concluded that you might have to remount the debug image if your device dies or restarts, which isn’t a big deal if you have a shortcut or mount it when you start the debugger.

Please make it easier for yourself and have a notepad or a text editor to put the commands in first that you will need to edit and reuse.


Finding BundleID via Altstore

This requires having AltStore installed (Windows and Mac only) but once it’s installed make sure to install the app you want first.




  1. Download iTunes from Apple’s website (not the Windows Store)

  2. Download libimobiledevice from https://github.com/libimobiledevice-win32/imobiledevice-net/releases/

  3. Plug in your iDevice (this will work over WiFi later).

  4. Open iTunes, click on your device and make sure you trust this computer on your iDevice. It will ask you for a passcode.

  5. Scroll down and check the box for WiFi sync in iTunes.

  6. Minimize iTunes and open a power shell and type

"cd \Users\yourusername\**_LocationOfFile_**\libimobiledevice.1.2.1-r1122-win-x64"

but fill in the correct information pertaining to where you saved and unzipped Libimobiledevice on your computer

  1. Run .\idevice_id.exe and copy the numbers and/or letters it gives you. This is your UDID.

  2. Open AltStore, press My Apps and then View App IDs. Write down the small letters of DolphiniOS, as shown in the prerequisites from above.

  3. Download the Developer Disk Image from either of these links. Note; you must download the version that is the same as your major iOS release. For example, a device running 14.4.2 will download 14.4.

    Download 1

    Download 2

  4. Unzip it and type

.\ideviceimagemounter.exe \Users\username\LocationOfFile\iosversionofFile\DeveloperDiskImage.dmg

If it fails to mount, restart both your iDevice and PC.

  1. Make sure you can run the app by running

.\idevicedebug -u UDID -n --detach run PackageID

where you replace UDID and PackageID with their values you found before.

MacOS install

  1. Make sure you have a github account logged in beforehand and Download the latest one that says master on the right and make sure it is MacOS and Extract it in Downloads folder.


  2. Enter the extracted zip file and extract file libimobiledevice.tar

  3. In the terminal move to directory by entering cd ~/Downloads/libimobiledevice-latest_macOS/usr/local/bin/

Then executing by entering chmod +x ./idev*

  1. Make sure your device is plugged in and that it is Trusted. Then go in Finder and click your device and Enable WiFi sync.

  2. Type in and enter


  1. It should of returned your UDID of you’re device

  2. Type without []

./idevicedebug -u [UDID] -n --detach run [BundleID]

Linux install (Debian)

  1. Download install.sh from github: https://GitHub.com/jkcoxson/DiOS-instructions (still under construction, message jkcoxson any issues you have)

  2. Plug iDevice in linux computer and trust computer

  3. Go to location of installation cd File/Location

  4. Give file permissions

sudo chmod +x ./install.sh

  1. To install just type in

sudo ./install.sh

  1. Give login password if needed

  2. At the end of install it should give your udid from usb and wifi if you have wifi setup and copy the udid (If your device was not connected or did not show just type in idevice_id to see udid if connected. If you are having trouble with idevice_id responding type the command: sudo service usbmuxd restart )

  3. If you are wanting to do over wifi then all you need to do is have the device plugged in and type this command. Idevicepair wifi on

  4. Type without []

idevicedebug -u [UDID] -n --detach run [PackageID]

Optional SSH Setup

The next steps are optional, to make it run from your iDevice. You will need to enable SSH on your PC.


Before you start please keep in mind that you will have to open the firewall for OpenSSH if it’s not allowed through. There are many tutorials on how to allow services or applications to go through the firewall of the computer. Sometimes this is automatic so you may not need to open it for openssh. You will also need to be the admin to set this up which by default most people.

You will also need your password and root username so the name your computer uses (On windows it’s called users) Not a Microsoft email.

To find your root username it would be in your main partition for windows so C:/Users/RootUsername

Note: for some reason if your username and password don’t work you will need to create a SSH key.


  1. Go to settings, apps, apps and features, manage optional features. Then search for OpenSSH server and install it.

You can set up the server to start automatically, open PowerShell in adninistrator type:

Set-Service sshd -StartupType Automatic

Then do this next one after from one above

Start-Service sshd

Open and ensure the firewall accept SSH connection, by default port 22, type:

New-NetFirewallRule -Name sshd -DisplayName 'Allow SSH' -Enabled True -Direction Inbound -Protocol TCP -Action Allow -LocalPort 22

To check if the port is listening :

netstat -a | findstr 22


  1. Then, in settings go to the Internet and then look for your IP address. Write that down.

  2. On your iDevice, open shortcuts and make a new one. Choose SSH.

  3. Put in your IP address, username and password to your computer. Make sure to give the exact location of libimobiledevice, so that includes all the way down to drive letter C:\example\fileloaction\libimobiledevice\idevicedebug. For the command put

C:Users\username\LocationOfFile\libimobiledevice.1.2.1-r1122-win-x64\idevicedebug -u [UDID] -n –detach run [PackageID]


  1. generating Authorized keys file, Create folder .ssh and navigate to it in powershell:

md ~/.ssh

cd ~/.ssh

then generate a random key, name it authorized_key and leave blank passphrase(by pressing enter):


Generating public/private rsa key pair.

Enter file in which to save the key (/home/demo/.ssh/id_rsa):authorized_keys

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

then it will indicate path location of authorized key

  1. Add the key of idevice to your Server:

On your idevice :shortcut > scripting > Run Script Over SSH > select Authentification SSH key > press on your key ed25519 or RSA between ur choice > share public key > copy

On Windows : go explorer folder to = C:\Users\Username.ssh

it should have two files: authorized_keys.pub and authorized_keys

Right click again authorized_keys and edit with notepad, you can erase everything in the file and copy the Pub Key that you got from idevice and save.

  1. Activate the PubKey in sshd_config

On Windows : go explorer folder to = C:\ProgramData\ssh

Edit in notepad sshd_config file: uncomment removing # line 34 and line 85 comment with #

Save and restart Openssh server, in powershell :

Restart-Service sshd

  1. Finish the Shortcut from your idevice filling Host and User info, and write the script following the upper point 4 for SSH PASSWORD AUTH.




  1. Hecka easy, run sudo apt-get install openssh-server (on systems with apt of course)

  2. Choose your method of allowing through iptables. I, jkcoxson, prefer ufw.

  3. If you use ufw, run sudo ufw allow 22

  4. Put your information and command into the shortcut.

Premade shortcuts

These are shortcuts that are premade by users that help with problems and a premade ssh activation method to select multiple apps.


Activate Debugger

This allows debugging apps over ssh with multiple apps and can be useful if you have multiple apps with jit or need a debugger to run.

Restart Apple service

This helps with problems with iTunes on windows not connecting over WiFi.

Restart Computer

This can help with problems with libimobiledevice not attaching a debug image. (This requires auto login to fully work for things like altserver and libimobiledevice).
