Insert device._langids = (1033,) between for device in usb.core.find(... and if match is not None... at line https://github.com/axi0mX/ipwndfu/blob/master/dfu.py#L16 see https://github.com/pyusb/pyusb/issues/139 PS. No pull request as they don't get merged. Patch can be applied locally.

@imifos, tried that and am getting the following error after entering the command sudo ./ipwndfu -p

Traceback (most recent call last):
  File "./ipwndfu", line 49, in <module>
    device = dfu.acquire_device()
  File "/Users/lachlanetherton/Desktop/AppleTech752/Exploit/dfu.py", line 16, in acquire_device
    device._langids = (1033,)
UnboundLocalError: local variable 'device' referenced before assignment

Here is my code:

Previously was getting the error:

On macOS 10.15.2 and trying to do this on an iPhone 5 (10.3.4), following this tutorial.

Hi, I'm sorry, I messed the above post up (facepalming myself). I have corrected it. You just need to move the patch down one line.

[ElectronicallyE]

@imifos, thanks. It now gives me this error the first time I try: ERROR: Exploit failed. Device did not enter pwned DFU Mode.

If I try again, the program hangs:

sudo ./ipwndfu -p
Password:
*** checkm8 exploit by axi0mX ***

After putting the device in DFU mode again, I can get the first error. Retrying sudo ./ipwndfu -p will either cause the phone to reboot or the program to hang.

[ElectronicallyE]

@imifos, did you have any further suggestions?

[imifos]

@ElectronicallyE No, sorry. Maybe try with an unmodified version of the tool? Just as side note: if you are using a VM, that will not work.

[ElectronicallyE]

@imifos, I've tried a number of times without modifying the code and faced the langid problem, even by typing sudo and python before the command. I'm in Australia, so I have the iPhone 5 GSM model, which I've heard doesn't have good success.

I'm using macOS, so I shouldn't have an issue. :(

[imifos]

@ElectronicallyE if you have an old Linux laptop laying around, it might be worth trying this... python 2, sudo apt install -y git libusb-1.0, clone the tool and go...

[ElectronicallyE]

@imifos, I try and get my hands on one ;). You think perhaps it's the latest macOS causing the problem?

[imifos]

@ElectronicallyE I had conflicts with libusb versions (homebrew). Give it a try if you want to know :)
