我是靠谱客的博主内向鸭子，这篇文章主要介绍[RK3399][Android7.1] 调试笔记 --- FwFactoryTool_v5.50_20190306拆包打包工具烧录后黑屏，现在分享给大家，希望可以做个参考。

Platform: RK3399-MID
OS: Android 7.1.2
Kernel: v4.4.83

问题：

FwFactoryTool可以提供给客户自主拆包，修改kernel logo 、开机动画、以及一些版本号等等再重新打包成update.img镜像包等；有客户反馈烧录了用工具生成的update.img镜像包，无法正常开机，画面黑屏；

问题日志：

解决方法：

看到FWFactoryTool5.50 使用手册有一项注意事项：

修改文件： build//target/product/verity.mk
