 ## 核心结论

-`Kindle Voyage 5.13.6` 应该走 `WatchThis`，不要走 `LanguageBreak`。
+这台 `KV + 5.13.6` 当前最稳的顺序，不是“`Get Started` 后立刻检查 `mkk/libkh/rp`”，而是下面这条完整链路：

-这次实操里，前面大部分失败都来自两个错误：
+1. 恢复出厂，语言只选 `English (United Kingdom)`
+2. 先输入;enter_demo, `;demo`
+  demo activation - yes - shipping mode error(电量低的原因)
+      1. 把 Kindle 接上 USB。
+      2. 我在根目录创建一个空文件 DONT_CHECK_BATTERY。
+3. `demo menu -> Sideload Content`，在这里接 USB，把 `.demo/` payload 写进去
+  - .demo/KV-5.13.6.zip
+  - .demo/demo.json
+  - .demo/goodreads/
+  - extensions/
+  - mrpackages/
+  - dashboard/
+  - Update_hotfix_watchthis_custom.bin
+4. `;dsts -> Help & User Guides -> Get Started`
+5. 按 demo 流程继续：`register this demo -> Skip -> standard`
+6. 遇到 `Configure Device` 就用隐藏手势回到主页
+7. 回到主页后搜索 `;uzb`，
+Update Error 2 -- 插usb，继续重启到 register this demo
+输入三个111
+standard 页面 (详见下面说明) ……

- 误走了 `LanguageBreak`
- 在 demo 菜单里点错了分支，提前进入了 `Resell Device` / `销售设备`
+**再接 USB，把 `Update_hotfix_watchthis_custom.bin` 放到根目录**
+8. `;dsts -> Device Options -> Update Your Kindle`
+9. 回到主页后搜索 `;log mrpi`
+10. 首页出现 `KUAL`

-对这台设备，正确思路非常简单：
-
-1. 用 `WatchThis` 进入 demo mode
-2. 只在正确的 `Sideload Content` 时机导入 `KV-5.13.6.zip`
-3. 用 `Get Started` 触发越狱脚本
-4. 安装 `KUAL/MRPI`
-5. 用 `renameotabin` 关闭 OTA
-6. 再部署并启动 `kindle-dash`
+这才是这轮实机验证真正成功的路径。

 ## 一次成功的正确路径

-### 1. 恢复出厂并进入 demo mode
+### 1. 恢复出厂并进入 demo menu

 1. 先恢复出厂设置。
 2. 语言选择页只选 `English (United Kingdom)`。
-   这一步非常关键，不要选中文。
-3. 到 Wi‑Fi 页面后，随便点一个网络，再立刻退回，不要真的联网。
-4. 在搜索栏输入 `;enter_demo`。
-5. 如果 `;enter_demo` 没反应，走备用入口：
-   - 用 USB 连接电脑
-   - 在 Kindle 根目录创建空文件 `DONT_CHECK_BATTERY`
-   - 弹出设备
-   - 回到 Kindle 搜索输入 `;demo`
-6. 如果看到 `Demo Activation`，点 `Yes`。
-7. 设备重启并进入 demo 流程后：
-   - 跳过 Wi‑Fi
-   - 店铺注册信息全部填假值
-   - `Fetching available demo types` 选 `Skip`
-   - demo type 选 `standard`
+3. 不要联网。
+4. 在搜索框输入 `;demo`。
+5. 进入 `demo menu`。

-### 2. 第一次出现 Sideload Content 时不要导入 payload
+如果这里没有进入 `demo menu`，再考虑备用入口；对本次实机成功路径来说，直接 `;demo` 就够了。

-1. 第一次出现 `Add Content` / `Sideload Content` 提示时，只点 `Done`。
-2. 这一步不要接 USB。
-3. 这一步也不要导入 `KV-5.13.6.zip`。
+### 2. 在 Sideload Content 页面导入 payload

-这是最容易做错的一步。第一次 `Done` 只是让 demo setup 继续往下走，不是真正的 payload 导入点。
+1. 在 `demo menu` 里点 `Sideload Content`。
+2. 到这个页面后，再接 USB。
+3. 在 Kindle 根目录确认下面三个东西存在：

-### 3. 跳过 misconfiguration 锁页
+```text
+.demo/KV-5.13.6.zip
+.demo/demo.json
+.demo/goodreads/
+```

-demo setup 完成后，大概率会落到 `Configure Device` / misconfiguration 页面。
+4. 安全弹出 Kindle。
+5. 回到 Kindle，点 `Done`。
+6. 退出 `demo menu`。

-不要点 `Configure Device`，直接做隐藏手势：
+如果你在 Mac 上手工操作，对应文件结构就是：
+
+```text
+/Volumes/Kindle/.demo/KV-5.13.6.zip
+/Volumes/Kindle/.demo/demo.json
+/Volumes/Kindle/.demo/goodreads/
+```
+
+### 3. 用 Get Started 触发越狱脚本
+
+1. 退出 `demo menu` 后，搜索输入 `;dsts`。
+2. 进入 `Help & User Guides`。
+3. 点 `Get Started`。
+
+接下来按这轮实测成功路径继续：
+
+1. 出现 `register this demo` 时，三个输入框都填 `111`
+2. `Fetching available demo types` 选 `Skip`
+3. 出现 demo type 时选 `standard`
+
+之后设备会重启。
+
+### 4. 遇到 Configure Device 时不要点进去
+
+重启后如果看到 `Configure Device`，不要点 `Configure Device`，直接做隐藏手势：

 1. 在屏幕右下角用两根手指同时轻点一下
 2. 两指立刻抬起
 3. 马上用一根手指从右下向左滑

-触发成功后会回到可操作界面。
+成功后会回到主页。

-### 4. 真正的 payload 导入点
+### 5. 用 ;uzb 暴露用户存储并写入 hotfix

-1. 回到可操作界面后，搜索输入 `;demo`
-2. 进入 demo menu
-3. 选择 `Sideload Content` / `导入内容`
-4. 到这一步再接 USB
-5. 在 Kindle 根目录创建 `.demo/`
-6. 把下面三个东西放进去：
+回到主页后：
+
+1. 搜索输入 `;uzb`
+2. 再接 USB
+3. 在 Kindle 根目录确认存在：

 ```text
-.demo/KV-5.13.6.zip
-.demo/demo.json
-.demo/goodreads/    <- 空目录
+/Volumes/Kindle/Update_hotfix_watchthis_custom.bin
 ```

-如果你在 Mac 上操作，可以直接用：
+如果没有，就把仓库里的：

-```sh
-mkdir -p /Volumes/Kindle/.demo/goodreads
-cp staging/watchthis/KV-5.13.6/KV-5.13.6.zip /Volumes/Kindle/.demo/
-cp staging/watchthis/KV-5.13.6/demo.json /Volumes/Kindle/.demo/
+```text
+dash/staging/watchthis/Update_hotfix_watchthis_custom.bin
 ```

+拷到 Kindle 根目录。
+
 然后：

-1. 弹出 Kindle
-2. 在 Kindle 上点 `Done`
-3. 退出 demo menu
+1. 安全弹出 Kindle
+2. 回到设备

-## 5. 触发越狱脚本
+### 6. 手工安装 custom hotfix

-1. 退出 demo menu 后，输入 `;dsts`
-   如果 `;dsts` 没反应，也可以从顶部下拉进入设置。
-2. 打开 `Help & User Guides`
-3. 再点 `Get Started`
-4. 设备会重启
-5. 越狱脚本会在下次启动时运行
+这一步不要再走 `Help & User Guides`。

-如果这里弹 `Application Error`，官方补救是：
+正确路径是：
+
+1. 搜索输入 `;dsts`
+2. 进入 `Device Options`
+3. 点 `Update Your Kindle`
+
+这一步跑完后设备会重启，并退出 demo 状态，回到正常主页。
+
+## 7. 用 MRPI 安装 KUAL / USBNetwork / KTerm / dashboard
+
+回到主页后，搜索输入：
+
+```text
+;log mrpi
+```
+
+如果 `mrpackages/` 已经预置到根目录，MRPI 会开始安装。
+
+实测成功判据：
+
+- 主页出现 `KUAL`
+- 如果这轮预置了 `KTerm`，后续也应该能找到 `KTerm`
+
+## 8. 进入 KUAL 后的顺序
+
+进入 `KUAL` 后，先执行：
+
+```text
+Rename OTA Binaries -> Rename
+```
+
+不要先跑 `Kindle Dashboard`，先把 OTA 关掉。
+
+## 9. 这轮流程里最容易做错的地方
+
+### 不要走 LanguageBreak
+
+`KV + 5.13.6` 应走 `WatchThis`，不要走 `LanguageBreak`。
+
+### 不要点 Resell Device / Remote Reset / Configure WiFi
+
+这几个都不是这条成功路径的一部分。
+
+### `Get Started` 后不要直接去找 `Update Your Kindle`
+
+先要完成：
+
+- `register this demo`
+- `Skip`
+- `standard`
+- 重启后隐藏手势回主页
+
+然后才是：
+
+- `;uzb`
+- 写入 `Update_hotfix_watchthis_custom.bin`
+- `Device Options -> Update Your Kindle`
+
+### `Update Your Kindle` 之前必须先写 hotfix bin
+
+`Update Your Kindle` 对应的是安装：
+
+```text
+Update_hotfix_watchthis_custom.bin
+```
+
+如果根目录里没有这个文件，就很容易出现 `Software Update / Update Error 2`。
+
+### 不要把 `mkk/libkh/rp` 当成当前这条流程里的唯一人工判据
+
+这轮最实用的成功判据是：
+
+1. `Update Your Kindle` 能正常跑完并重启回主页
+2. `;log mrpi` 能执行
+3. 首页出现 `KUAL`
+
+## 10. 如果某一步出错
+
+### `Get Started` 后出现 Application Error
+
+按上游 `WatchThis` README 的补救方式：

 1. 长按电源键强制重启
-2. 再进 demo menu
+2. 再进 `demo menu`
 3. 再执行一次 `Sideload Content -> Done`
 4. 这次不要再接 USB

-## 6. 成功判据
+### `Update Your Kindle` 报 `Update Error 2`

-对这台设备，下面这些现象说明越狱已经落地：
+先检查 Kindle 根目录里是不是真的有：

- Kindle 用户存储根目录出现 `mkk`
- Kindle 用户存储根目录出现 `libkh`
- Kindle 用户存储根目录出现 `rp`
-
-如果这三个目录都没有，基本就是前面的 `WatchThis` 没真正成功。
-
-## 7. 安装 KUAL / MRPI / kindle-dash
-
-越狱落地后，把这些目录复制到 Kindle：
-
-```sh
-rsync -a staging/post-jailbreak-root/extensions/ /Volumes/Kindle/extensions/
-rsync -a staging/post-jailbreak-root/mrpackages/ /Volumes/Kindle/mrpackages/
-rsync -a staging/post-jailbreak-root/dashboard/ /Volumes/Kindle/dashboard/
+```text
+Update_hotfix_watchthis_custom.bin
 ```

-然后：
+注意不要把 macOS 生成的：

-1. 弹出 Kindle
-2. 回到首页搜索输入 `;log mrpi`
-3. 等安装完成
-4. 首页会出现 `KUAL` 卡片
+```text
+._Update_hotfix_watchthis_custom.bin
+```

-## 8. 启动顺序
-
-进入 `KUAL` 后，先做这个顺序：
-
-1. `Rename OTA Binaries -> Rename`
-2. 再运行 `Kindle Dashboard`
-
-不要先跑 `Kindle Dashboard`，否则后面如果 OTA 没关掉，还存在自动升级把越狱覆盖掉的风险。
-
-## 9. kindle-dash 默认行为
-
-本项目默认不会在 Kindle 本机实时渲染页面，而是定时去下载一张图片来显示。
-
-因此：
-
- 如果没有联网，`Kindle Dashboard` 看起来会像“卡住”
- 如果刷新计划不覆盖当前时间，会显示 `kindle is sleeping`
- 图片最好直接按 Voyage 原生分辨率出图：`1072 x 1448`
-
-默认抓图脚本在：
-
- `src/local/fetch-dashboard.sh`
-
-默认刷新计划在：
-
- `src/local/env.sh`
-
-## 10. 这台设备上确认过的坑
-
-### 不要走 `LanguageBreak`
-
-`KV + 5.13.6` 应走 `WatchThis`。误走 `LanguageBreak` 会导致：
-
- `;demo -> Yes -> 重启 -> 回普通系统`
- `;uzb`、`;dsts` 行为异常
- 反复进入错误的 demo 分支
-
-### 不要点 `Resell Device` / `销售设备`
-
-这个分支会把流程带到 shipping mode / demo 出厂流程，和 `WatchThis` 正常路径无关。
-
-如果你是在 `WatchThis` 流程里，demo menu 里真正要点的是：
-
- `Sideload Content`
-
-不是：
-
- `Resell Device`
- `Remote Reset`
- `Configure WiFi`
-
-### 第一次 `Add Content` 只能点 `Done`
-
-真正要接 USB 导 payload 的时机，是秘密手势之后再次 `;demo -> Sideload Content` 的那一次。
-
-### 看到左上角只有一小块图片，不一定是失败
-
-这通常只是图片尺寸不匹配。
-
-例如本项目自带的 `sleeping.png` 只有 `600x800`，放到 Voyage 上就只会显示在左上角一部分区域。
-
-## 参考

- WatchThis 包内说明：`watchthis-jailbreak-r03.zip` 中的 `watchthis-release/README.md`
- 项目主说明：`README.md`
