Android14 OTA差分包升级报Package is for source build

制作好差分包，使用adb线刷模式验证ota升级，出现E:Package is for source build错误

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E:Package is for source build

这个问题使用adb线刷才有， 如果使用代码升级验证不会出现。

本地验证时，注释以下代码
