My sister has asked if I can rescue the photos and audio recordings on her old Moto G4. The SD card is formatted as internal memory, the phone isn't rooted, and as far as I know USB Debugging is turned off.
The issue stopping me is that I can't use the phone because the screen is just complete rainbow static... like in this photo of another phone:
I'm guessing everything she wants will be on the SD card, and I know that if I could get the decryption key I could decrypt the card using my PC, but without a working phone I feel a bit stuck.
Is there anything I can do without fixing the phone? Can I get the phone fixed, or will that change the decryption key, making the SD card useless?
