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 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, make sure to have a microSD card reader on hand before proceeding.

Your device may not show your installed games after the ctrtransfer. This is due to the tickets being removed by the transfer, which is why you back them up. They will be restored at the end of the guide.

**For now, connecting your device to the internet is REQUIRED to continue after the 2.1.0 ctrtransfer.**

#### Overview of steps
|
|
|
|
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](otp-info) 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.
|
|
|
|
The OTP is a requirement to use arm9loaderhax.
|
|
|
|
#### What you need

|
|
|
* You will need to have booted into Decrypt9
