Checking Everything Has Been Wiped

  1. On the Hekate home screen select Launch > CFW sysMMC, CFW on Device Memory (you need to do this because there’s a save file management bug which will cause a black screen if you boot OFW immediately after reseting sysMMC).
  1. Once it boots into CFW, press and hold the Power button until the Power Menu pops up, then choose Power Options > Restart.
  1. On the Hekate home screen select Launch > OFW sysMMC Normal Stock.

  1. Follow the instructions to set the Switch up again.

  1. If you receive a notice informing you the microSD was used on another Switch, you can press Delete (this won’t affect an emuMMC or any CFW data on the microSD card).
  1. Connect to the eShop (you will have to link an account and update the system firmware if it’s not on the latest version).

If you can access the eShop you are not banned. If you receive a notice saying ‘The use of online services on this console is currently restricted by Nintendo.’ you are already banned.
