由于VF 架构，所以镜像的打包时间可能存在偏差，如 boot.img 和客制化的一些镜像打包可能会在 vendor 侧进行打包。

使用adb方式验证

进入recovery模式

adb reboot recovery

稍等一会界面会提示

Now send the package you want to apply 
to the device with "adb sidelaod <filename>"...

输入命令开始升级

adb sideload Z:\xxx\xxx\ota\update.zip

update.zip是制作好的差分包

报ErrorCode::kPayloadTimestampError (51)

由于打包时间差异，所以导致时间戳比较乱。

解决办法

提取目标版本和源版本的镜像中的时间戳。
按时间戳大的（最后编译）进行打包到 ota 升级包中

/vendor_ap_s0/build/make/tools/releasetools/ota_utils.py
