On the way

三步简单“破解”Kindle Fire步骤：首先安装豌豆荚，将ES文件浏览器或R.E.管理器安装到Kindle Fire；其次，将系统设置中的Allow Installation of Applications（From Unknown Sources）修改为ON(开启)，这步类似android机器中的“应用程序”中的“位置来源(允许安装非电子市场提供的应用程序)”，这样拷贝到Kindle Fire硬盘上去的apk程序就能自由安装和卸载。最后一步，安装“区域设置”中文补丁，Kindle Fire中的英文菜单可部分汉化成中文，完美版的汉化将会在后续更新。

Amazon has just released the latest update for the third-gen Kindle which will let you keep your personal documents in the cloud and easily access them from any Kindle app or newer devices. For many Kindle users, it’s a fairly major update that takes advantage of Amazon’s cloud prowess and provides yet another feature that other e-readers like the Nook and Sony Reader don’t offer.

The company first announced that it would be storing your personal files in the cloud when it unveiled the new $79 fourth-gen Kindle, Kindle Touch, and the Kindle Fire tablet. Amazon will also be keeping the third-gen Kindle around, except it’s now called the Kindle Keyboard.

Previously, personal files, which can include text documents, pictures, and PDF files, were delivered directly to your Kindle device via your Kindle email address but weren’t archived anywhere. Now your personal documents will be treated just like Kindle e-books. Amazon’s Whispersync technology will also synchronize your last page read, annotations, and bookmarks for personal documents. Unfortunately, Amazon says PDF files won’t be compatible with the Whispersync features.

Once in Amazon’s cloud, your personal documents can be re-downloaded on the new Kindle Touch and fourth-gen Kindle. That’ll make upgrading to one of the newer models even more painless. Amazon says it’s working on bringing the personal file synchronization feature to the Kindle Fire and Kindle apps “in the coming months.” The new features won’t be available on older Kindle models at all, which doesn’t come as too much of a surprise.

There are quite a few programs and web services that can be really useful to Kindle owners. This post compiles 17 of these that every Kindle user should know about, ranging from eBook conversion programs to services that can broadcast your favorite websites to your Kindle.

越狱有风险，破解需谨慎。

1. Jailbreak
去网页http://www.mobileread.com/forums/showthread.php?t=88004 下载 kindle-jailbreak-0.4.N.zip。解压后，目录下有一堆文件，是对应不同的 Kindle 版本的。[HOME] -> [MENU] > Settings 下可以看到序列号和MAC地址。
k3g = K3 3G US (序列号开头是B006)
k3w = K3 WiFi (序列号开头是B008)
k3gb = K3 3G UK (序列号开头是B00A)
俺的小三是B006开头的，所以使用 update_jailbreak_k3g_install.bin 文件。插上 K3 的 usb 线，把对应文件拷贝到 K3 的根目录下。在计算机上停止 K3 usb连接，然后在 K3 上进行下列操作 [HOME] -> [MENU] > Settings -> [MENU] > Update Your Kindle。在升级过程中会显示有错误，错误码是U004，没有关系，这是正常的。K3会自动重启动。

2. 安装 usbNetwork
去网页http://www.mobileread.com/forums/showthread.php?t=88004 下载 kindle-usbnetwork-0.28.N.zip。解压后，像上一步一样选择升级文件。B006的机器使用 update_usbnetwork_0.23.N_k3g_install.bin。同样插上usb线，拷贝到根目录，断开usb，然后升级。这次会显示升级成功，然后自动重启。

3. 修改 usbNetwork 配置
重启完毕之后，再次连接USB到计算机。K3 的根目录下会多出一个目录 usbnet。进入该目录，将 DISABLED_auto 文件名改为auto。进入etc子目录，用文本编辑器，如记事本(Notepad)，来修改config文件。这是UNIX格式的文本文件，不要修改成DOS格式。只要把两处false改成true，保存。
K3_WIFI=”true”
K3_WIFI_SSHD_ONLY=”true”

4. 制作密钥
去http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html 下载 puttygen.exe。运行该软件，点击 Generate，然后根据提示随机移动鼠标来产生随机密钥。搞完之后，要把 Public key for pasting into OpenSSH authorized_keys file 里面生成的文本粘贴到一个空白的文本文件，应该是巨长的一行。然后保存到 K3 的 usbnet/etc 目录下，文件名是 authorized_keys，这个是公钥。然后点击软件的 save private key 按钮，取个名字，保存到本地硬盘，这个是私钥，步骤6需要使用这个文件。需要的话，可以在Key Passpharse填写一个密码来保护私钥文件。公钥私钥是配对使用的。断开USB连接，[HOME] -> [MENU] > Settings -> [MENU] > Restart，重启K3。

5. 显示 K3 的 IP 地址
先开启无线，显示 WiFi 图标后，[HOME] -> [MENU] > Settings，然后输入 alt+u, alt+q, alt+q。这就是著名的 711 页面。在页面上半部分有 MAC 地址，下半部分显示有 IP Address。一般无线路由器上的DHCP可以根据MAC地址保留IP地址，在路由器里设置一下之后，IP 地址就不会再改变了。

6. SCP 客户端
下载http://winscp.net/download/winscp429.zip。解压缩，软后运行winscp。点击 New 按钮。Host Name 填写上一步得到的 IP 地址。User Name 填 root。Private Key File 选择步骤4保存的私钥文件。Protocol 选择 SCP。左侧点击 SCP/Shell, 然后将 Lookup User Groups 前的勾去除。左侧点击Directories，右侧在Remote Directory中填写/mnt/us。最后点击 Save 按钮保存。将来再次使用的时候，选中保存的配置，直接 login 就可以了。运行之后，左侧是计算机的文件夹。右侧是 K3 文件夹。

如果需要显示中文文件名，经测试，winscp 的 Protocol 选择 SFTP 而不是 SCP。点左侧Environment，右侧UTF-8 encoding for filenames 选择 On 即可。SFTP 的传送速度比 SCP 稍慢。

注意：/mnt/us = USB 连接时 K3 的根目录。拷贝东西到 /mnt/us 下的各个子目录即可。

7. Kindle 文件库的刷新
拷贝到 /mnt/us/documents 下的文件 K3 不会自动检测到，所以需要一个刷新机制，否则每次传完之后需要重启。
用SCP连上K3，进入usbnet目录，按鼠标右键 New -> File，文本中粘贴 dbus-send –system /default com.lab126.powerd.resuming int32:1，加一个回车，然后保存。随便取个名字，比如 refresh_kindle。以后每次传完文件，回到usbnet目录，右键点击这个文件，选择 Custom Commands -> Execute. 这样不用重启，K3 也能自动更新文件库。

8. SSH 客户端
想要用命令行登入 K3 进行危险操作的同学，可以http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html 下载 putty.exe。用同样的私钥建立SSH连接即可。
