做了那么多年伸手党，终于自己干了点事情，给国内的小白翻译了一篇国外大神的 3DS 破解的教程
看到小白们成功后开心的回来感谢，心里还是挺舒服的，这大概就是帮助别人的感觉吧~
下面就是我发的帖子，有兴趣可以看下
首先，这是 A9LH 团队官方的升级指南（11 月 3 日更新的）：
这是原网页
Updating A9LH
Last Update: 3 Nov 2016The actual installation of arm9loaderhax itself consists of payload files installed into the NFIRM partitions on your device’s NAND chip, which is soldered to the motherboard itself. These payloads are updated rarely and only really serve the purpose of launching arm9loaderhax.bin from the SD Card, which is, in our case, Luma3DS.
If you do not know what version of arm9loaderhax you are running, just install the latest version with these steps. Installing the latest version while already on the latest version will have no effect.
If you have a PIN set on Luma, you must temporarily turn it off to do these steps. You can re-enable the PIN after the update.
If you are using a payload that does not init the screen on its own (such as Bootanim9), you will need to rename it to arm9loaderhax_si.bin instead of arm9loaderhax.bin
Once arm9loaderhax has already been installed, Old 3DSs can use data_input_v4. Only the initial Old 3DS install needs data_input_v3 to be compatible with an old SafeA9LHInstaller version that can be launched with the browser. The versions only refer to revisions of the zip to be compatible with different installer versions, and are not the same thing as updating a9lh itself (the payload files).
These steps will also update your various payloads and the AES key database.
What you need
aeskeydb.bin -
data_input_v4.zip -
The latest release of Luma3DS
The latest release of arm9loaderhax
The latest release of SafeA9LHInstaller
The latest release of Hourglass9
Instructions
For all of these instructions, OVERWRITE any existing files on your SD card.Section I - Prep work
Delete any existing aeskeydb.bin from the root of your SD card
Delete the a9lh folder from the root of your SD card if it exists
Copy aeskeydb.bin to the /files9/ folder on your SD card
Copy Hourglass9.bin from the Hourglass9 zip to the /luma/payloads/ folder on your SD card and rename Hourglass9.bin to start_Hourglass9.bin
Copy arm9loaderhax.bin from the SafeA9LHInstaller zip to the /luma/payloads folder on your SD card
Rename arm9loaderhax.bin in /luma/payloads to down_safea9lhinstaller.bin
Copy the a9lh folder from data_input_v4.zip to the root of your SD Card
Copy the contents of the arm9loaderhax zip to a9lh folder on your SD card
Copy arm9loaderhax.bin from the Luma3DS zip to the root of your SD card, overwrite existing files
Reinsert your SD card into your 3DS
Section II - Payload update
Boot the device while holding D-Pad down
Press (Select) to update arm9loaderhax
Power off the device and put your SD card back in your computer
Delete the a9lh folder from the root of your SD card
Delete down_safea9lhinstaller.bin from /luma/payloads
Section III - Configuring Luma3DS
Reinsert your SD card into your 3DS and boot holding (Select)
Use the (A) button and the D-Pad to turn on the following:
“Autoboot SysNAND”
“Use SysNAND FIRM if booting with R (A9LH)”
“Show NAND or user string in System Settings”
If you are using a New 3DS, you should also enable the following:
“New 3DS CPU” to “Clock+L2(x)”
This will increase the framerate of many games, but may cause instability in others
If some games do not work properly, disable this option and try again
Press Start to save and reboot
Section IV - CTRNAND Luma3DS
Open FBI
Select “SD”
Navigate to arm9loaderhax.bin, then press (A) on it and select the “Copy” option
Return to the FBI main menu with (B)
Select “CTR NAND”
Select “”
Select the “Paste” option, then press (A) to confirm
Exit with the home button
Power off your 3DS and remove the SD card
Boot with the SD card removed while holding (Select)
Booting the device at least once with the SD card removed will allow you to configure the CTRNAND based luma installation
Use the (A) button and the D-Pad to turn on the following:
“Show NAND or user string in System Settings”
If you are using a New 3DS, you should also enable the following:
“New 3DS CPU” to “Clock+L2(x)”
This will increase the framerate of many games, but may cause instability in others
If some games do not work properly, disable this option and try again
Reinsert your SD card, then press Start to save and reboot!然后做个简略的翻译教程：
一、简单说明
1、更新必须用最新的 LUMA 包（现在最新的是 LUMA V6.67）
2、如果你自己不知道自己的 A9LH 的版本，那么请直接更新最新版（意思就是都要用最新的文件，新的文件和老的不配套，不能新老混用，而且大小姐的 payload 也不能和别人的混用）
3、如果你在 LUMA 设置了 PIN（开机密码），一定要先清除再升级
4、data_input_v4 这个文件新三老三都可以用，但是最初版的貌似要用 V3 版
二、准备工作
准备以下文件，必须都要用最新版的（强调都要用新的，切记不能新老混用，其实就是 V1 和 V2 的 Payload 不能混用，所以都用最新最保险）
有些文件原贴是 BT 种子，国内不好下，所以我打包上传到网盘了
aeskeydb.bin
data_input_v4.zip
Luma3DS
arm9loaderhax
SafeA9LHInstaller
Hourglass9三、升级步骤
第一部分
1、从 SD 卡的根目录删除 aeskeydb.bin（如果有的话）
2、删除 SD 卡里面的 “A9LH” 整个文件夹（如果有的话）
3、拷贝最新的 aeskeydb.bin 到 SD 卡里的 /files9 / 目录下
4、拷贝 Hourglass9.bin 到 SD 卡 /luma/payloads / 目录下，然后重命名为 start_Hourglass9.bin（不懂拷贝这个文件意义何在，貌似没用上整个啊，但是原教程如此，建议还是照做）
5、拷贝 SafeA9LHInstaller.zip 压缩包里面的 arm9loaderhax.bin 到 SD 卡 /luma/payloads 目录下，并且重命名为down_safea9lhinstaller.bin（重要步骤）
6、拷贝 data_input_v4.zip 压缩包里面的 “A9LH” 文件夹到 SD 卡根目录下
7、从最新的 LUMA3DS 包里，拷贝 arm9loaderhax.bin 到 SD 卡根目录，如果有老文件，那么覆盖即可
8、拷贝 arm9loaderhax.zip 里面 / A9LH / 文件夹到 SD 卡根目录
9、把 SD 卡插回去第二部分
1、按住十字键的下开机
2、进入 SafeA9LHInstaller 后按 SELECT 键来升级 arm9loaderhax
3、关机，拔出 SD 卡插上电脑
4、删除 SD 卡根目录下整个 / A9LH / 目录，删除 /luma/payloads 目录下的 down_safea9lhinstaller.bin
第三部分
1、插上 SD 卡，按住 SELECT 键开机，进入 LUMA 菜单
2、把这些选项勾上
- “Autoboot SysNAND”
- “Use SysNAND FIRM if booting with R (A9LH)”
- “Show NAND or user string in System Settings”
3、如果是新三，把超频的选项也勾上
- “New 3DS CPU” to “Clock+L2(x)”
官方说明是可以明显改善一些游戏掉帧和卡顿的问题
4、按 START 保存，机器会自动重启
第四部分（应该是无 SD 卡开机相关的）
1、开机后进新版的 FBI（应该是 2.42 的）
2、选 SD 卡，再选 arm9loaderhax.bin，按 A，选择 “Copy” ，然后返回根目录
3、选 CTR NAND，点击 “
”，按 A，选择 “Paste”，再按 A 确定 4、退出 FBI，关机拔掉 SD 卡
5、不插 SD 卡并按住 SELECT 开机进入 LUMA 菜单（这个是无 SD 卡的 LUMA）
6、勾上一下选项
- “Show NAND or user string in System Settings”
7、新三勾上超频选项
“New 3DS CPU” to “Clock+L2(x)”
8、插上 SD 卡重启
这样就结束了
