Help/Support I need to restore my saved game

[rhipone 0 iPhone X 12.4]

Hi, this is a long story, so I try to explain it

I got an iPhone X ios 13.3 so I decided to update it to ios 14.6( latest version).

My phone was JB so I made a backup and restore RootFS before update it.

I wasn't unable to restore my backup, so I start my phone as "new one" and then, try to restore it from iTunes, but it was impossible

I got my backup, and I extract all the files from it, but now, I can't place it into my phone and get my data back, specially with Zero City, because this game save game on local file and not on the cloud( I contact them and told me that was impossible to them to restore my ID, they can see it but not restore it)

Well, now I'm looking for something to inject or copy or something this files into my phone since it's an iPhone X and the JB it's not ready yet

Any idea to do this? Thanks

Did you save SHH blobs  if so you can downgrade back to whatever version you saved without it being signed
