pymobiledevice3 update to 2.31.0 breaks enabling JIT

[hscumbie]

After the new release of pymobiledevice3 (Version 2.31.0), JIT is now failing with error:

The process 'altjit' failed with code 1. Could not connect to device <udid>. The process 'python3' returned unexpected output. Error: No such command 'start-quic-tunnel'.

It seems pymobiledevice3 no longer supports the start-quic-tunnel command and now requires start-tunnel instead.

A workaround is to downgrade pymobiledevice3 to Version 2.30.0 by executing python3 -m pip install pymobiledevice3==2.30.0.

EDIT: Also, when downgrading pymobiledevice3, you'll also need to downgrade pip package construct to version 2.10.69 by executing python3 -m pip install construct==2.10.69. This fixes the stream.tell() issues.

EDIT 2: The CommandLineTools version of Python needs to be explicitly called when downgrading pymobiledevice3 and construct. This can be done by executing:

/Library/Developer/CommandLineTools/usr/bin/python3 -m pip install pymobiledevice3==2.30.0 construct==2.10.69

EDIT 3: DolphiniOS users: Use the beta version of DolphiniOS (4.0.0b1 or greater) from AltStore to fix the random crashing issue when launching a game.

EDIT 4: Kudos to @orhid for finding a fix for KeyError: <Epoch.INITIAL: 0>. The solution is to force pip package qh3 to version 0.15.1 (qh3==0.15.1).

Not working for me.

A small detail I forgot to add. construct 2.10.70 breaks pymobiledevice3 2.30.0 (pymobiledevice3 2.31.0 was actually pushed to fix this issue with construct but broke other things). Downgrade construct by executing python3 -m pip install construct==2.10.69.

It's done. nice workaround.

Try executing which python3 and report back what it says. I think AltStore uses the Xcode version of Python and won’t work with user installed Python. This will tell us what your system is defaulting to when downgrading construct and pip.

[bryycee]

Hey i’m having the same problem and i’ve been following along and Im getting the exact error do I did the command which python3`` and i’m getting /usr/bin/python3 any help?

[romanhmln]

Had the same issue yesterday, but went with @hscumbie workaround and now it fires fine.

python 3.9.6
construct 2.10.69
pymobiledevice3 2.30.0

Try using the versions above and restarting AltServer after you're done. Also make sure that you've updated the XCode Command Tools in the first place.

[bryycee]

what should i do then what commands do i run ?

[hscumbie]

Make sure you have Xcode command line tools installed by running xcode-select —install (that’s a double minus btw idk why my iPhone won’t let me type it). The terminal response will either say they’re installed and up to date, or prompt an install. Also, see what Python binary your PATH variable is pointing to (echo $PATH). My issue was I installed Python 3.12 from python.org. If you run the “update shell” script that comes with the installer, it will alter your $PATH to now point to the python.org binary when executing python3 rather than the Xcode Command line python.

[bryycee]

Im still confused on what to do. I did all of this and I need specific instructions can you guys tell me what to run so I can fix this issue thanks

[bryycee]

or please add me on discord i need help ill pay anyone my user is fizzrld

[FightMan01]

Hi! After downgrading I'm getting a new error. Can anyone help me out?

Try this in terminal: /Library/Developer/CommandLineTools/usr/bin/python3 --version. It should return Python 3.9.6, indicating that you have CommandLineTools Python installed. If this fails, try executing xcode-select --install and install the CommandLineTools.

Once you have verified the CommandLineTools Python is installed, now run:

/Library/Developer/CommandLineTools/usr/bin/python3 -m pip install pymobiledevice3==2.30.0 construct==2.10.69

^ The above command explicitly calls the CommandLineTools version of Python that is used by AltServer for enabling JIT.

Thanks, it worked for me.

[shanegillio]

Is anyone getting this issue where it says it failed to start service?

[hscumbie]

Did you check if the DeveloperDiskImage was mounted with python3 -m pymobiledevice3 mounter auto-mount?

Not sure why the last comment never uploaded, but anyway! I have this version of AltServer working for me, so curious if it will work for everyone here AltServer.zip

[mbrown0603]

After a while of trying to enable JIT I found this forum, tried everything... and IT WORKED!!! Thank you so much!

Would you mind sharing what system you're on and what version of macOS you're using? I'm still trying to get mine to work without much luck. I think my hardware is too old.

@shanegillio I tried it, and it didn't work... at first I thought it did, because there was no error message, but after waiting for like 2 minutes, I finally tried to load up the Wii menu in Dolphini, which gave the same old screen of "Waiting for JIT" -- and eventually it it finally gave the timeout error of not being able to connect to device... "The process 'python3' timed out."

I'm on a 2019 MBP 16" on macOS 14.1.2 and an iPhone 14 Pro Max on 17.1.1. I downgraded construct and pymobiledevice3 like everyone else mentioned. I double checked to make sure pymobiledevice3 is activated, as well as making sure that the DeveloperDiskImage was mounted successfully by running python3 -m pymobiledevice3 mounter auto-mount

Still doesn't work. Any thoughts?

With the following

• pymobiledevice3==2.30.0
• construct==2.10.69

Im getting this exact error, my computer asks me to enter my password as it wants to make changes and then this error pops up. if anybody could please help that would be greatly appreciated.

[sach491]

Just to note that I was getting the error shown at the beginning of the thread, but after downgrading the versions I end up getting this new error.

[afromankenobi]

Hey guys!

I managed to fix the Process 'altjit' that failed with code 1. Could not connect to device X. The process 'python3' returned unexpected output. KeyError: EnumIntegerString.new(3, 'PUBLIC_KEY') error. It's related to a new to the new CoreDevice Framework introduced by iOS17:

Starting with iOS 17.0, Apple introduced the new CoreDevice framework to work with iOS devices. This framework relies on the RemoteXPC protocol.

To make it work, make sure you:

• Install the latest version of pymobiledevice: python3 -m pip install -U pymobiledevice3.
• Create a trusted tunnel: sudo python3 -m pymobiledevice3 remote start-tunnel.
• Enable JIT from AltServer for the desired application as usual.

This method should work for people with iOS > 17.

[liaabreua]

hi! i tried this but i keep getting: "Error: No such command 'start-tunnel'" could anyone help please?

I'm getting stuck while create a trusted tunnel, are there any steps missed? I've added my MacBook to trust devices on my iPhone
