长虹UD42C6080id救砖

sxgpic

一台UD42C6080id安卓智能电视，在U盘升级过程中小区断电导致变砖，通电开机无任何反应。
估计MBOOT启动程序和EMMC主程序都已损坏。
用RT809F编程器写入同型号正常机器的MBOOT程序后，通电开机，呼吸灯和屏幕背光亮起，呼吸灯不停闪烁，说明MBOOT已成功修复。
插入装有升级文件的U盘，不能进入U盘升级模式，一直停留在黑色背景和呼吸灯闪烁状态。
用RT809F编程器查看启动信息，看到如下输出：

说明EMMC中root分区已经被破坏，电视启动过程中加载了LINUX内核，找不到root分区（主程序分区），导致内核恐慌，死机。

按照网络上的说法，开机时同时按住电视上的音量+按键和电源按键，也无法令电视进入U盘刷机模式，因此无法更新EMMC中的root分区。
大家说，我这个情况，该怎么救砖？

飞线刷emmc

用RT809F编程器写入同型号正常机器的MBOOT程序后。问一下师傅，用RT809F如何写这个引导程序？

MBOOT网上有下载，RT809F用VGA线连接电视，写入MBOOT就行了。

RT809F可以飞线刷EMMC？哪里可以找到这个机型的EMMC主程序？

wsf

809f不行 h可以

wsf

emmc主程序淘宝购买
