三星的Knox Warranty Bit原理_移动开发_编程开发_程序员俱乐部

它是如何触发的？

这个值的状态是烧录在主板上，无法刷写修改， 从0到1 不可逆，除非替换硬件

If a non-Knox boot loader or kernel has been installed on the device, Knox can no longer guarantee the security of the Knox container. As a result, the Warranty Bit will be burned to 0X1, indicating that this device can no longer use the Knox container service.

If the Knox bit has been burned:

A new Knox container can no longer be created on such a device
The data encrypted and stored in an existing Knox container can no longer be retrieved

进入刷机模式以后， Knox WARRANTY VOID: 0x01.表时Knox安全套件已经失效，那么ro.boot.warranty_bit＝1，三星大多数app会根据这个值来决定，你有没有权限继续使用三星官方应用。

为了安全考虑，三星将不会让你使用如三星支付、三星健康等app
