You only need a way to launch homebrew so you can extract & inject your Shuffle save.I have already done the last update so my system is at 11.1.0-34U I couldn't get the updated date otherwise. Is there anything else that I could use besides a GW card? Or is that my best bet since I have already updated?
I'm not up-to-date as of which entry points work on 11.1 or not, but you just need to find and use one of them.
