樂視New c1s系統(tǒng)降級變磚，求救磚

默默兇 · 發(fā)表于 2017-2-13 17:08

先前按照論壇的方法給系統(tǒng)降級，就是這個教程：

(出處: ZNDS智能電視網(wǎng))

刷完之后就變磚了，沒有視頻輸出，插電沒反應。根據(jù)搜的資料和刷路由器的經(jīng)驗判斷可能是uboot壞了，但是沒有技能儲備TTL線刷，而且主板上看不出哪個端口是TTL端口，不知道版主能不能幫忙救磚。@hao501802766

通電之后左右燈亮，中間應該是紅外接收器開孔

用官方的固件刷！
軟刷可以用優(yōu)盤，強刷必須用SD。

感覺已經(jīng)黑磚了，U盤做了引導都沒反應

迅雷下載不提供服務了嗎，點帖子里的下載鏈接直接跳到上傳加速的活動頁面了

@hao501802766 好版，TTL連接上以后接通盒子電源，讀到代碼

然就就開始一直不停循環(huán)滾動下面這一串代碼，可有辦法解決嗎

請問樂視盒子LETV-S3也可以用這個方法嗎？

不了解S3，你可以拆開看看有沒有TTL接口，有的話應該可以，不過這個需要有Linux和單片機的技術儲備，沒基礎的話還是找人修吧，你看我這都搞不定
