Do you have the correct model of Note 10 +? Only the SM - N975F is compatible.
I used these instructions: https://doc.e.foundation/devices/d2s/install, but they weren’t enough. When I encountered an obstacle, I had to do some online searching for the solution.
The good news is, I posted all the solutions on this thread. So just find my name and see what I wrote. Maybe that will solve your problem. https://community.e.foundation/t/samsung-galaxy-note10-d2s-documentation-suggestions/35184/9
