Samsung Galaxy Z Fold4 5G SM-F936U 256GB Phantom Nero per parti di ricambio

For parts When I brought it here on eBay it had the issue that it did not open all the way as you can see in the picture. I tried to fix it by following a YouTube video where you would use a paper clip to scrap off from the hinges dust and threads. After doing so it would not turn on. It would just vibrate when pushing the power button but nothing would show in the screen. All black. Selling this for parts. This was the repair I attempted to do but now the phone no longer boots up. It tries to by vibrating but you can’t see anything on the screen. https://youtu.be/SZ6B1aEjqp8?si=VS33sK5Vhh_KHQJg
