So the touch screen actually works, but the screen is dead. So she just got a new phone and she went to log in to her Nintendo account in Pokemon Masters to download her play data, but it says she never linked an account, even though she's pretty sure she did.
Regardless, her account and everything is locked on the old phone which technically still works, but without any way of viewing the screen.
It's not rooted and doesn't have USB debugging turned on. Is there a way to root it and possibly transfer the app's data over to the new phone? Or is this a completely lost cause? She's super bummed out, so I'm willing to try anything if there's any possibility.
