In this article, I’m going to talk about SYSNAND and EMUNAND, and how to update them using DAYBREAK. This should also work for building your own custom ROM, as long as you have a daybreak compatible device. This is the most common way to update the SYSNAND on a Switch. If you don’t have a daybreak compatible device, you can try the emuMMC method.


In order to use EMUNAND on a Switch, it is necessary to be using a supported version of sysNAND. A switch with a genuine booted sysNAND running on 11.0.1 or higher should boot on 12.0.0 emuNAND. You should also wait one week to get the results you expect. If you do not see any changes in your device after updating firmware, you can use a backup bootloader like Atmosphere.

If you are running an EmuNAND-based console, you can update your sysNAND by creating a clone of the internal NAND. You can then boot into the emuMMC version and use the CFW version without risking being banned. Alternatively, you can use EmuNAND for homebrew and game backups, as long as you have a 64GB microSD card installed in the system.

If you have a newer firmware version and are running EmuNAND, you should also check if your phone supports it. If not, then try using a different system or using an older firmware. If your phone supports both EmuNAND, it should work fine. But if you’re running an old firmware, EMUNAND may cause problems. The firmware update process is more complicated than that, but it’s worth trying.

To begin updating the sysNAND on a Switch, you must first download EmuNAND, then you must have enough space on your computer. After installing EmuNAND, you must remove the original game cartridge from your Switch. Then, follow the instructions that accompany the ROM. If you’re unsure of the steps, just follow the links below. This will guide you through the entire process.


If you’re wondering how to update SysNAND, you’re not alone. The process for emuNAND is nearly identical to that for SysNAND, so you don’t need to worry about getting confused. If you’ve never used EmuNAND, here are a few steps to get you started. Also, if you’re new to emuNAND, read this guide first before you attempt the process with SysNAND.


UPDATING SYSNAND WITH NEW DAYBREAK: You can now use Daybreak with the official firmware of the Atmosphere. This tool is also included in the official firmware of the Atmosphere since version 0.14.0. In order to use this tool, you must first download the latest firmware for the Atmosphere. After installing the latest firmware, you must run the following commands:


If you are interested in building sysNAND on your Switch, it is best to use choidujour instead of Daybreak. The former is still unbanned, but the latter is not. In either case, you should never connect to Nintendo servers after using it. Otherwise, your sysNAND backup will be useless for online play. If you don’t want to risk this, consider using emuMMC or emuNAND.
