HTC 刷机备忘

笔者对 HTC 手机有着深厚的感情，从 HTC G2 到 HTC M8，经历了 HTC 的鼎盛和衰落。本文记录了一些常用的刷机方法和 hack 命令，以作备忘。

获取解锁码

前往 http://www.htcdev.com/bootloader 获取官方解锁码。

刷入解锁码

fastboot flash unlocktoken Unlock_code.bin

Relock

fastboot oem lock

刷入 Recovery 方法

常规方法

adb reboot bootloader
fastboot flash recovery recovery.img

重启后进入 recovery 界面

fastboot reboot
adb reboot recovery

或者可以在 fastboot 界面直接进入 recovery

在 S-OFF + LOCKED 状态下刷入第三方 Recovery 的方法

准备 ZIP 文件

在 S-OFF + LOCKED 情况下通过 adb 工具线刷时，所用的 recovery.zip 包里必须包括 android-info.txt 和 recovery.img。而这个 android-info.txt 的内容必须符合你的手机信息，以我的 Sprint 版为例，其内容是：

modelid: PN0720000
cidnum: 11111111
mainver: 5.03.651.3
btype:1
aareport:1
DelCache:1
hbootpreupdate:3

查询以上信息的方法为：在 adb 中输入 fastboot getvar all 即可看到，然后将所需的 modelid、cidnum、mainver 信息修改到 android-info.txt 文件中。

android-info.txt 文件可以从官方 RUU 中提取，然后把上面查询到的信息替换到里面即可。

最后将 recovery.img 和 android-info.txt 一起打包到 zip 压缩包中，并放入 adb 工具的文件夹里即可开始下面步骤了。

（刷 radio 也是同理，必须在 zip 压缩包中加入 android-info.txt。）

adb reboot bootloader
fastboot oem rebootRUU
fastboot flash zip recovery.zip

fastboot reboot
