I don’t know what to do. I tried turning on the first 2 boxes, turning off Spotpass, download boot.firm and yet, I still get no access to Pretendo.

Hello.

This is not actually a ban error code. This usually points to an error with Luma, Nimbus, or both.

I am going to walk you through a full list of steps that should fix any kind of issue regarding this error code.

Please follow them in this exact order presented here.

Try this:

  1. Open Universal Updater
  2. Search “luma” and download the Luma3ds boot.firm
  3. Still in Universal Updater, also search “Nimbus” and re-install it (no need to uninstall first)
  4. Turn off your console
  5. Hold SELECT and turn it on
  6. Make sure both of the top 2 options have an X in them. Hit START to save and return to the 3DS home menu.
  7. Open Nimbus now and press START to finish the Nimbus update process from earlier in Step 3.
  8. Open Nimbus again and click Pretendo.
  9. Open Friend List and tell us if you see any error now.
