Error 2002-2634 (010000000000001F)

Remove your game card if you updated firmware and you are getting Error Code: 2002-2634 for Program: 010000000000001F. You can enable nogc to avoid this crash, but that will prevent you from playing gamecards until you do this after updating your Switch to a newer supported firmware.

Battery is dead and Switch won't power on

You most likely have autorcm enabled.
Connect your Switch to your charger and let it charge for an hour. Afterwards you can push a payload like usual.

This applies only to unpatched Erista devices.

Partition-based vs file-based EmuNAND

Partition-based EmuNAND:


  • Has the least chance of corruption.


  • Creating a new EmuNAND requires you to partition your SD card, thus existing files on the SD will get deleted.
  • Migrating to a new SD card or making a backup of your EmuNAND is much more complex.
SD File-based EmuNAND:


  • Very easy to transfer or make a backup of.
  • Creating a new EmuNAND is easier, and won't require you to partition your SD card.


  • Your EmuNAND setup has a higher chance of getting corrupted.
    • This applies to both FAT32 and exFAT users.
  • Transferring games between your SD card and your EmuNAND via system settings is not possible.
    • This is due to an unfixed bug.

I updated to 12.1.0 and some homebrew applications are not working

Unfortunately since atmosphere 0.19.0, some old homebrew applications need to be recompiled in order to work.
This is due to the changes Nintendo has made in 12.0.0 and changes in atmosphere.
In this situation you can either wait for the developer to recompile their application, or you may
downgrade to 11.0.1, and use Atmosphere 0.18.1 until the majority of homebrew applications get recompiled.

Archivebit fix (Mac users)

Boot first into Hekate, then press ToolsArch bit • RCM Touch • Pkg1/2Fix Archive Bit.

How to enter the homebrew launcher

There are two ways to launch homebrew:

  • By holding R and clicking on a title in your home menu.

Switch not booting after update

If your device is not booting into Horizon OS after an update then you may try one of the three fixes from down below:

You may be running an old CFW version. Please ensure you are on the latest
CFW version. You may read this guide to learn how to update your CFW.

Bluescreen after updating Atmosphere
