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. Note that the terms EmuNAND and RedNAND refer to slightly different implementations of [the same concept](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. Đảm bảo bạn có một đầu đọc thẻ microSD trước khi tiếp tục.
{: .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. 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}

**Không bao giờ format lại một 2DS trong khi ở bản <6.0.0, hoặc là bạn sẽ không thể hoàn thành quá trình thiết lập ban đầu và sẽ BRICK máy (máy thành cục gạch)!**
{: .notice--danger}

**Không bao giờ nâng cấp New 3DS đang chạy 2.1.0 (một bản hệ thống chỉ dành cho Old 3DS) hoặc là bạn sẽ BRICK máy! You MUST restore a NAND backup or CTRTransfer back to standard New 3DS firmware first!**
{: .notice--danger}

**Để máy New 3DS ở 2.1.0 vào trạng thái ngủ sẽ gây BRICK KHÔNG HỒI PHỤC ĐƯỢC***    
**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.**    
**Một khi đã xuống 2.1.0, bạn nên lập tức tiếp tục để tránh mọi khả năng sự cố này xảy ra!**

#### Tổng quan các bước

{% capture notice-2 %}

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. File OTP này cần thiết để cài arm9loaderhax, và **không thể** dùng chung với máy khác.
<br><br>
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.

#### Hướng dẫn

##### Section I - Prep Work

1. Power off your device
1. 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

    ![]({{ base_path }}/images/screenshots/ctrtransfer-file-layout.png)
    {: .notice--info}

1. Copy `SafeCTRTransfer.dat` from the SafeCTRTransfer `.zip` to the root of your SD card
1. Copy _the contents of_ the `starter` folder in `starter.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
  + 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)*
