Firmware

1. CFW = Custom firmware
2. OFW = Official firmware
3. /!\ If you used an emuNAND, the sysNAND will be untouched and you will necessarily be on the CFW!

NAND

1. It is the memory, based on semiconductors, which is non-volatile (kept even without a power supply, unlike RAM which is volatile) and rewritable

eFuse

1. These are nano fuses integrated into the Tegra chip (NVIDIA) which equips the Nintendo Switch, these fuses burn out (or burn out) after a firmware update. This is an anti downgrade device
2. > The Nintendo Switch has 64 eFuses (they're really microscopic)
3. /!\ If you used an emuNAND, the eFuses will not be impacted, since everything is virtual!

Warning

1. Fully charge your Switch
