Issues with iPad4,4 (iPad Mini 2) on macOS Big Sur #233

Open nodeg opened 3 years ago

nodeg commented 3 years ago

Describe the issue I am not able to use the tools with the supported iPad4,4 since the tool tells me I have an unsupported device, although I provided it with the corret ipsw from ipsw.me:

$ ./vieux -i iPad_64bit_10.3.3_14G60_Restore.ipsw

Additional context

After looking into the Python code I found out that line 137 from ipsq.py

devicemodel = str(localdevice.getmodel())

does not work as intended, so I hardcoded my devicemodel

devicemodel = 'iPad4,4'

After running the script again I overcame the issue mentioned above but now I am stuck with another one where I have no clue:
