Help/Support Gamecenter issue

[airtight3ip 3]

Apologies in advance, for a potentially duplicate question, but I started with the modded app, without connecting to game center, now I have progress that I don't want to loose again.  Ive tried to connect to Game Center but it asks about restoring previous progress, which I don't.  Ive tried looking in the documents and data section, tried deleting iCloud data, but without true filesystem access, I am at a loss as to how to backup/keep my current progress, or overwrite Game Center with my current progress.  Thank you in advance for any response.

Back up your current modded save, assuming you have root access. Restore your game, then click the gamecentre again to unlink your account. Restore the save with the one you backed up and you should be able to connect to the game centre on the vanilla app.

 

If you do not have root access then you most likely need to jailbreak your iDevice to be able to access your saved data.

Thanks for the response.  My device is Jailbroken on 11.3.1 using Electra, but unfortunately afc2 is not updated that I know of and I haven't found a suitable work around.  unrestr1ctor was a potential work around but I don't think there a working version for 11.3.1  If you have any other leads i would appreciate it.  Thanks again
