If you downgrade to 2.1.0 on a 2DS or New 3DS and left 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}

2.1.0 버전에서는 뉴 3DS의 microSD Management 기능을 이용하여 SD 카드에 파일을 전송할 수 없습니다. 진행하기 전에 SD 카드 리더기를 준비하세요.
{: .notice--info}

ctrtransfer 후에는 설치한 게임들이 보이지 않을 수 있습니다. 이는 ctrtransfer 과정 중 티켓이 제거되기 때문이며, 티켓을 백업해야 하는 이유이기도 합니다. 티켓은 이 가이드의 마지막 부분에서 복원됩니다.
{: .notice--info}

** 2.1.0 ctrtransfer 이후의 작업을 진행하기 위해서는 무선 인터넷 연결이 필수입니다.**
{: .notice--warning}

**2.1.0 ctrtransfer를 진행하기 전에 청소년 보호 기능을 비활성화시키세요. 비밀번호를 모를 경우 [이 사이트](https://mkey.salthax.org/)를 참고하세요.**
{: .notice--warning}

**유저가 설치한 티켓들은 ctrtransfer 과정 중 모두 삭제되며 백업 파일로 추후에 복원됩니다. 반드시 백업을 만들어두세요!**
{: .notice--danger}

**6.0.0 버전 이하의 2DS는 절대로 포맷하지 마세요. 초기 설정을 완료하지 못하고 그대로 벽돌이 됩니다!**
{: .notice--danger}

**2.1.0 버전(구 3DS 펌웨어)의 뉴 3DS는 절대로 업데이트하지 마세요! 100% 벽돌이 됩니다! 먼저 NAND 백업을 복원하거나 ctrtransfer 과정을 통해 정식 뉴 3DS 펌웨어로 돌아가세요!**
{: .notice--danger}

{% capture notice %}
**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 the device is on_; this does not apply to turning the device off.**
**The 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!**

#### 단계별 개요

In this section, we will be flashing your console'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 console. 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 console specific files (such as `moveable.sed` and `SecureInfo_A`) to it, then fixing the title databases.

#### Instructions

##### 섹션 I - 준비 작업

이 단계를 진행하기 위해서는 Decrypt9로 부팅되어 있어야 합니다.

1. Press (Select) on the main menu to eject your SD card, then put it in your computer
2. Copy the 2.1.0 `.bin` and `.bin.sha` from the ctrtransfer `.zip` to the `/files9/` folder on your SD card
3. SD 카드를 다시 3DS에 삽입하세요.
4. Press (B) to get to the Decrypt9 main menu

##### 섹션 II - ctrtransfer

**Having a backup of _your_ device's NAND is REQUIRED. You will be prompted to create one as part of the steps if you do not already have one.**
{: .notice--danger}

**If you do not know whether or not you already have a NAND backup, create one when prompted by pressing (A) just to be sure.**
{: .notice--danger}

**If you do not have enough space to create the backup, you can either backup to a different SD card or clear space on your current SD card by pressing (Select) on the Decrypt9WIP main menu to eject your SD card and allow it to be swapped with a different SD card or to clear space on your current SD card**
{: .notice--danger}

1. Go to "SysNAND Options", then "CTRNAND Transfer", then "Auto CTRNAND Transfer"
2. Input the key combo given, then select the 2.1.0 ctrtransfer image when prompted by pressing (A)
3. If you do not already have a NAND backup, **backup SysNAND to `NANDmin.bin` when prompted by pressing (A)**
  + **Having a backup of _your_ device's NAND is REQUIRED.**
  + **Skipping this backup will result in the LOSS of all installed games and saves!**
4. Allow the transfer process to proceed automatically, this will take some time
5. Once the transfer is complete, press (B) to go back
6. Press (Select) to eject your SD card
7. Delete the 2.1.0 ctrtransfer image `.bin` and `.bin.sha` from the `/files9/` folder on your SD card
8. Press (Start) to reboot without reinserting your SD card
  + While on 2.1.0, the device will black screen on boot if your SD card is inserted before the home menu loads
  + Every time the 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 the 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

___

The initial boot of 2.1.0 can take slightly longer than a standard boot on some devices.
{: .notice--info}

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