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. EmuNANDとRedNANDは[同じ理論](http://3dbrew.org/wiki/NAND_Redirection)の少々違う実装です。
{: .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. 事前にmicroSDカードリーダーをご用意ください。
{: .notice--info}

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. パスワードがわからない場合は、[このサイト](https://mkey.salthax.org/)をご覧ください。 十三歳以下の子供のためのNNIDをリンクしているため、「保護者による使用制限機能」を無効にできない場合、全ての使用制限を「制限なし」に設定してください。**
{: .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}

**バージョン6.0.0以下で2DSでは本体が壊れる為絶対に初期化しないで下さい。**
{: .notice--danger}

**New 3DSで2.1.0へのダウングレード後は本体設定から更新を実行すると3DSが壊れるのでご注意下さい。 You MUST restore a NAND backup or CTRTransfer back to standard New 3DS firmware first!**
{: .notice--danger}

{% capture notice %}
**2.1.0のNew 3DSをスリープモード（3DSを折りたたむと、自動的にスリープモードになる。）にすると完全に壊れるの絶対にしないで下さい！**    
**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. それをせずに時間が経ってもスリープモードになりません。**    
**2.1.0バージョンへのダウングレードを実行したら、ためらわず進んでこういう可能性を避けてください！**

#### ステップの概要

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. このOTPファイルはarm9loaderhaxをインストールするために必要です。他の本体では**利用できません**。

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.

#### 必要なファイル

#### 手順

##### セクション I -　準備

1. Power off your device
1. パソコンにSDカードを入れます
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. Reinsert your SD card into your device
1. Copy `SafeCTRTransfer.nds` from the SafeCTRTransfer `.zip` to your DS flashcart
1. Power on your device

##### 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
  + 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
  + この不具合は、次のページでデバイスをリストアする後で直します
