[velejaj]

Hi,
I have iPad Air 4.1, MacBook Pro on macOs Catalina 10.15.4
I'm trying to downgrade from 12.4 to 10.3.3. and I get same error all the time.

I tried with ./vieux -i and with python3 vieux -i, I get sam error.

When I type ./vieux -p I get this

I tried to download IPSW file few times and it didn't help.

Any suggestions?

Thanks

i have a same question
i use ipad air 4.2 with mac os 10.15.4
when i type ' python3 vieux -i ' its not working
ERROR: Unsupported model...

I finaly did my downgrade on my old white unibody MacBook with High Sierra on it.
Only vieux worked.
So, the error is probably because of Catalina.

@velejaj @thanhmom123 Hey! I had the same problem "ERROR: Unsupported model...". This comment helped me today to downgrade my iPad mini 2 4,4 iOS 12.4.4 to 10.3.3. Link: "Seems that is a problem with code signing executable."
