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 gunna be restored at th' end 'o th' guide.

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 from the device until a backup is restored. Under NO CIRCUMSTANCES should ye skip creatin' a backup!**

#### Overview 'o steps

In 'tis section, we gunna be flashin' ye console's [CTRNAND](https://www.3dbrew.org/wiki/Flash_Filesystem#CTR_partition) partition to 2.1.0 in order to take advantage 'o an oversight in 2.1.0 fer th' purpose 'o extractin' th' [OTP](https://www.3dbrew.org/wiki/OTP_Registers) unique to ye console. 'Tis OTP file be required to install arm9loaderhax, 'n **cannot** be shared wit' other consoles.

'Tis be accomplished by [installin' a premade ctrtransfer image](https://www.reddit.com/r/3dshacks/comments/4zhe4a/) containin' 2.1.0, copyin' ye console-specific files (such as `moveable.sed` 'n `SecureInfo_A`) to it, then fixin' th' title databases.

#### What ye need

* Ye gunna need to have booted into Decrypt9
* Th' 2.1.0 ctrtransfer image fer ye device 'n region     
*(if your device is not from one of these regions, just pick one)*:
