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. Huomaa, että termit EmuNAND ja RedNAND viittaavat [saman konseptin](http://3dbrew.org/wiki/NAND_Redirection) kahteen hiukan erilaiseen toteutukseen.

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. Ensure you have a microSD card reader available before proceeding.

**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".**

**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}

**Never format a 2DS while on a version <6.0.0 or you will be unable to complete initial setup and will BRICK!**
{: .notice--danger}

**Never update a New 3DS running 2.1.0 (an Old 3DS firmware) or you will BRICK! You MUST restore a NAND backup or CTRTransfer back to standard New 3DS firmware first!**

**Putting a New 3DS on 2.1.0 in sleep mode is known to cause an UNRECOVERABLE 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. It is not on a timer or anything like that.**    
**Once on 2.1.0, you should continue without delay to avoid any possibility of this happening!**

#### Overview of steps

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. This OTP file is required to install arm9loaderhax, and **cannot** be shared with other consoles.

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.

#### Tarpeet

* DS flashcart that works on your device version
* The latest release of [SafeCTRTransfer](https://github.com/d0k3/SafeCTRTransfer/releases/latest)
* The 2.1.0 CTRTransfer image for your device and region     
*(if your device is not from one of these regions, just pick one)*:

#### Ohjeet

##### Vaihe I – Valmistelut

1. Sammuta konsolisi
1. Aseta SD-korttisi tietokoneeseesi
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 `SafeCTRTransfer.dat` from the SafeCTRTransfer `.zip` to the root of your SD card
1. Aseta SD-korttisi takaisin konsoliisi
1. Copy `SafeCTRTransfer.nds` from the SafeCTRTransfer `.zip` to your DS flashcart
1. Käynnistä konsolisi

##### Section II - Launch SafeCTRTransfer

1. Start your DS flashcart from your device
1. Boot `SafeCTRTransfer.nds` using your flashcart
1. Select the correct option for your system version
  + 4.X.X -> "4.x SafeCTRTransfer"
  + 6.X.X -> "6.x SafeCTRTransfer"
1. Reboot the system, then go to System Settings, then "Other Settings", then "Profile", then "Nintendo DS Profile"
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
  + Tämä prosessi kestää jonkin aikaa
  + 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
  + This will be fixed once you restore your device in the next page

*(Screen distortions or discolorations are normal for some devices while on 2.1.0, they will go away once you restore your backup)*
