Terrain Data Issue

I get bad or no terrain data error. I have ter_pend at 35 and it stays there.

What i already tried:

  • i manually uploaded the terrain (from terrain generator) into the SD card. I have the Terrain folder and i uploaded 400km radius around the location i want to fly.
  • when i plug in the terrain stards loading (ter_load) rises, but eventually stops.
  • MP is up to date.

Any leads? Any ideas?
