If you are unable to boot your device, please look for the section relevant to you and follow the instructions.

If you still cannot solve your issue and need to reach out for help, please paste the contents of all relevant .log files from the root of your SD card into a [Gist](https://gist.github.com/), then come for help prepared with a detailed description of your problem and what you've tried.

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).

## Cannot inject H&S on Gateway downgraded device

This is caused by Gateway implementing a very shoddy downgrade method which leaves two versions of each app on the system. One of them is unused, but it confuses the H&S inject system, causing it to inject into the wrong one.

Note that if you have any payload files other than `GodMode9.firm` in the `/luma/payloads/` folder on your SD card, holding (Start) on boot will display a "chainloader menu" where you will have to use the D-Pad and the (A) button to select "GodMode9" for these instructions. 
{: .notice--info}

1. Launch GodMode9 by holding (Start) during boot
1. Navigate to `[1:] SYSNAND CTRNAND` -> `title` -> `00040010`

  + **New 3DS or New 2DS JPN**: `20020300` -> `content`
  + **New 3DS or New 2DS USA**: `20021300` -> `content`
1. 注意，文件夹里有两组app和tmd文件，一组带有大写的后缀（`.TMD`和`.APP`），一组带有小写的后缀（`.tmd`和`.app`）
1. 按住(R)键的同时，按(Y)键新建一个目录
1. Press (A) to confirm the name `newdir` (it does not matter what the folder is called)

1. Press (B) to decline relocking write permissions if prompted
1. 在每个大写字母后缀（`.TMD`和`.APP`）的文件上按(L)键选中它们
1. 按(Y)键复制这些文件
1. 进入`newdir`文件夹
1. 按(Y)键粘贴这些文件
1. 选择”Move path(s)”
1. 大写字母后缀的文件将被移动到`newdir`文件夹下
1. Press (Start) to reboot your device
1. Retry the H&S injection
1. If this still doesn't work, move the uppercase extension files back to the `content` folder, then move the lowercase extension files to the `newdir` folder, then retry the H&S injection
