Description
【前提条件】
None
【测试步骤】
1. 烧写最新MCU mot 0.0.9
2. 然后烧0068的版本，这个mcu是 0.0.7 这里会生一次降级MCU降级，在降级过程中断电
3. 再烧0075的版本，MCU 0.0.9， 这里会生一次降级MCU降级，在降级过程中断电
4. 最后循环升降
【预期结果】
每次均能正常启动
【实际结果】
循环第十三次后，设备反复进行进入recovery
初步分析为key 未备份

Hi, 刘强，
帮忙验证一下VB版本：
ftp://cdiot@192.168.87.46/Pre_figure/VerifyBuild/Pre_figure_turbox-c2130c-la1.1-qssi12-dev/20230301/202303012056-2775
验证方法：
1. 正常开机，确认一下屏幕能否正常显示，亮灭屏，背光调节是否正常,重启３０次。
2. 异常开机，进入recovery模式时，lcd是否还会有显示。

【复现结果】
1、正常开机，重启30次，正常显示，亮灭屏，亮度调节正常
2、异常开机，删除/persist/key和/metadata/vold/*/key后，重启设备进入recovery模式，lcd呈黑屏状态，没有显示
