What it means
According to Nintendo, 2005-0012 on Nintendo Switch may indicate an issue with the microSD card in use, and its steps refer to downloads that cannot complete because of that card. The procedure separates the system version, the card's seating, the card itself (another card or formatting) and the console's system memory. If it fails with another card and in the system memory, or if you have no other card to test, Nintendo sends it to repair. The code does not prove the card is broken.
