iOS 9 backup corrupt while downgrading

[Stelyios]

Hi everyone,

So i initially had iOS 8.4.1 and than upgraded to 9.0and than 9.01 and the beta, and the celular data toggle for my apps was not working... So I decided to downgrade to 8.4.1 again, and I read on youtube that i could edit the document in the backup to restore it. Now I have done that and I cant seem to get it to work. It has corrupted. Could someone please help me out? Here is the two areas I modified:

</dict>
<key>Build Version</key>
<string>13A344</string>
<key>Device Name</key>
<string>Stelyio's iPhone</string>
<key>Display Name</key>

Is there something wrong here?

Which iOS version were you on when you created the backup? When did you try to downgrade?

 

[Stelyios]

I was on the latest software at the time 13A344 or 9.0 I tried to downgrade two nights ago

An iOS 9 backup will not work after a downgrade to iOS 8.4.1. The changes you made to the backup would have made the backup unusable even if you went back to iOS 9. Can you undo the changes you made to the backup?

Even though you downgrade to 8.4.1 again, iOS 9 backup will not work. Maybe this is why your document is corrupted.
