Summary:The invention relates to a method for automatically upgrading a security mode based on a minimum system backup, the mode being upgraded by an autop mode. When the upgrading fails, an environment variable bootmode is set to be equal to a safemode so as to enter the safety mode upgrading, and the firmware is upgraded by a url mode. Automatically upgrade to the target firmware without extra user operations after the safe mode is started, optimizing the user experience. In addition, the method backs up the smallest system after the firmware upgrade is completed, only the basic system and the upgrade module need to be backed up, and a large number of programs of the service layer are reduced. 本发明涉及种基于最小系统备份实现的安全模式自动升级方法，其通过autop方式升级，当升级失败时，设置环境变量bootmode使其等于safemode，从而进入安全模式升级，通过url方式对固件升级。安全模式启动后无需用户多余的操作即可实现重新自动升级到目标固件，优化用户体验。此外，本发明在固件升级完成后，进行最小系统的备份，只需备份基础系统和升级模块，少去业务层大量程序。
