If you have already hacked your device before and have a EmuNAND based CFW setup, this guide deals exclusively with SysNAND and you should follow all instructions from within or applying to SysNAND. Merk at EmuNAND og RedNAND refererer til litt forskjellige implementeringer av [det samme konseptet](http://3dbrew.org/wiki/NAND_Redirection).
{: .notice--info}
If you downgrade to 2.1.0 on a 2DS or New 3DS and leave Wireless Communication off, you can re-enable the wireless by removing the battery and unplugging the charger for several seconds then booting back up.
{: .notice--info}
If you've been using the New 3DS's microSD Management to transfer files to your SD card, this will no longer work on 2.1.0. Gjør deg sikker på at du har en microSD kortleser før du fortsetter.

To use the [magnet](https://en.wikipedia.org/wiki/Magnet_URI_scheme) links on this page, you will need a torrent client like [Deluge](http://dev.deluge-torrent.org/wiki/Download)
{: .notice--info}
**For now, connecting your device to the internet is REQUIRED to continue after the 2.1.0 CTRTransfer.**
{: .notice--warning}
**Disable the parental controls of your device before doing the 2.1.0 CTRTransfer. If you do not know the password, see [this](https://mkey.salthax.org/) site. If you cannot disable parental controls because the linked NNID is for a child under 13, you can instead set all parental control options to "do not restrict".**
{: .notice--warning}
**Performing a CTRTransfer will remove all user-installed tickets (which allow access to games) from your device until the created backup is restored.**
{: .notice--danger}
**Formater aldri en 2DS når du er på en versjon lavere enn 6.0.0, ellers vil du ikke kunne gjennomføre førstegangsoppsett og du vil BRICKE!**
{: .notice--danger}
**Oppdater aldri en New 3DS som er på versjon 2.1.0 (en versjon for Old 3DS) eller du kommer til å BRICKE! You MUST restore a NAND backup or CTRTransfer back to standard New 3DS firmware first!**

**Å sette en ny3DS på 2.1.0 i hvilemodus har en tendens til å forårsake en UGJENOPPRETTELIG brick!**
**This only happens when shutting the lid _while your device is on_; this does not apply to turning your device off.**
**Your device only enters sleep mode when the lid is closed. Den går ikke på tidsur, eller noe lignende.**
**Når du er på 2.1.0, bør fortsette med en gang for å unngå enhver mulighet for at dette skjer!**
In this section, we will be flashing your device's [CTRNAND](https://www.3dbrew.org/wiki/Flash_Filesystem#CTR_partition) partition to 2.1.0 in order to take advantage of an oversight in 2.1.0 for the purpose of extracting the [OTP](https://www.3dbrew.org/wiki/OTP_Registers) unique to your device. Denne OTPfilen kreves for å installere arm9loaderhax, og **kan ikke** deles med andre konsoller.
This is accomplished by [installing a premade CTRTransfer image](https://www.reddit.com/r/3dshacks/comments/4zhe4a/) containing 2.1.0, copying your device specific files (such as `moveable.sed` and `SecureInfo_A`) to it, then fixing the title databases.

#### Instruksjoner
##### Seksjon I - Forarbeid
1. Remove your SD card from your device, leaving it on the Homebrew Launcher, then insert your SD card into your computer
1. Create a folder named `CTRTransfer` on the root of your SD card if it does not already exist
1. Copy the 2.1.0 `.bin` and `.bin.sha` from the CTRTransfer `.zip` to the `/CTRTransfer/` folder on your SD card
1. Copy `safehax.3dsx` to the `/3ds/` folder on your SD card
+ Hvis enheten fryser, kan du tvinge den til å skru seg av ved og holde av-knappen og så prøve igjen
1. Launch safehax from the list of homebrew
+ You may have to scroll down to see this option
+ Hvis enheten fryser, kan du tvinge den til å skru seg av ved og holde av-knappen og så prøve igjen
1. If the exploit was successful, you will have booted into SafeCTRTransfer
##### Section III - CTRTransfer
1. Allow the SafeCTRTransfer initialization and safety checks to proceed automatically
+ If you get an error, ensure you have all files in the correct locations and that you have enough free space on your SD card as detailed in [Get Started](get-started)
1. When prompted, input the key combo given to confirm CTRTransfer to 2.1.0
+ This process will take some time
+ This process will automatically create a backup of your device's NAND at `/ctrtransfer/<serialnumber>_nand.bin`
+ If you get a critical error, [follow this troubleshooting guide](troubleshooting#ts_transfer)
1. Once this process has completed, remove your SD card from your device to reboot
+ The reboot will take about 2 seconds to trigger
+ While on 2.1.0, your device will black screen on boot if your SD card is inserted before the home menu loads
+ Every time your device is rebooted on 2.1.0, you will need to take out your SD card before boot and put it back in after the home menu loads
+ For now, leave your SD card out as you will be copying files to it in the next page
+ Dette vil bli fikset når du gjenoppretter enheten på neste side

*(Skjermartefakter eller misfarging er normalt for noen enheter under 2.1.0, de vil forsvinne når du gjenoppretter sikkerhetskopien din)*
