乐视New c1s系统降级变砖，求救砖
先前按照论坛的方法给系统降级，就是这个教程：乐视盒子c1s3.0亲测降级教程，强制粗暴，简单五步！https://www.znds.com/forum.php?mod=viewthread&tid=487719&fromuid=4454480(出处: ZNDS智能电视网)
刷完之后就变砖了，没有视频输出，插电没反应。根据搜的资料和刷路由器的经验判断可能是uboot坏了，但是没有技能储备TTL线刷，而且主板上看不出哪个端口是TTL端口，不知道版主能不能帮忙救砖。@hao501802766
通电之后左右灯亮，中间应该是红外接收器开孔

用官方的固件刷！
软刷可以用优盘，强刷必须用SD。
感觉已经黑砖了，U盘做了引导都没反应 用官方的固件刷！

或者刷第三方的

请问乐视盒子LETV-S3也可以用这个方法吗？
不了解S3，你可以拆开看看有没有TTL接口，有的话应该可以，不过这个需要有Linux和单片机的技术储备，没基础的话还是找人修吧，你看我这都搞不定
