GALAXY Z FLIP 6 broken inner display (probably dead touch too) [HELP]

My Galaxy Z Flip 6 is broken. Its inner display is totally black, probably due to leaking pixels. I am practically broke, so I can't get it repaired, but I want to use its Snapdragon 8 Gen 3 processor—no questions asked. By the way, I know the pattern lock, so I didn't steal it; it belonged to my grandfather, but he bought a new phone after its display died.

​My available hardware:

​Laptop: Low-end 4GB RAM HP laptop running Lubuntu

​Secondary phone: Poco M3 Plus

​Cables: 2 USB Type-A to Type-C cables

​Budget: $0 (I cannot even buy a USB-A to Type-C adapter to connect a mouse)

​What I have tried:

​USB debugging is off, so scrcpy doesn't work.

​Tried a direct cable connection, but Knox security blocks access.

​The inner display touch is completely unresponsive.

​The cover screen won't let me enter settings, has no apps, and doesn't seem to support Smart View or provide a way to do anything.

​Pleaseeeeessss..... tell me how I can tap into its processor and get it working.
