winCE  车机  瑞虎517款车机，，无碟导航，没有复位按钮，没有SD卡插槽，只有一个USB接口

前几天弄导航升级，把系统的文件夹，XCEshell内的文件移动了目录 ，，现在开机出现logo后就重启，，

现在无法进入车机系统，车机没有复位按钮，不知道怎么进BootLoader，

拆开看到主板有debug_TX和deuug_RX触点，就接了ttl线，，调试输出的信息如下面文档，

还有个RX和TX接口，，接ttl开机输出是乱码，也不知道怎么回事，，

求助：如何通过ttl进入BootLoader或者文件系统，我只要把那个文件移动回原来的目录即可。

求助：如何刷机或者救砖

求助：维修刷机的思路，或者进入BootLoader的思路，或者如何刷机，或者改变引导~~还有一个事情，，有办法用TTL串口和内核交互吗？？？能交互也许还能有点办法~~本人动手能力强，只是没有维修思路

下面是主板背面图和串口输出信息
