android 4.03启动出错,显示"Encryption Unsuccessful"该如何解决

android 4.03启动出错,显示"Encryption Unsuccessful"
把android 4.03移植到产品上,进入anroid启动动画一段时间后,显示“Encryption Unsuccessful”然后显示“power off”按钮,如果有朋友知道是什么原因请告知下,谢谢！

[解决办法]
想启动可以先把加密去掉
system/core/init/builtins.c 

C/C++ code

- property_set("ro.crypto.state","encrypted");+ property_set("ro.crypto.state","unencrypted");- property_set("vold.decrypt",1);
