求助！！！S905L-B机顶盒升级EMMC后，可以线刷，不能启动。
本帖最后由 fancyzj 于 2021-4-19 17:41 编辑如题，前两天没事，看着手里闲着的64GEMMC，想着给盒子换上加点空间。换上后线刷正常，但是TTL跑码如下现在不知道咋救活了。原机4G的片子换回去一个鸟样。大神给指导下呗，不胜感谢！！！

帮忙顶顶
谢谢！ 看来大神们已经不再关注这类低端机型了。 帮你顶顶
bootloader损坏了。 这是一个很好的学习平台，学习学习。 我也碰到了,天邑TY1208晶晨S905M-B,线刷不了啊总出错在1%什么读取镜像失败的。。、、连TTL就无限那些EMMC:0;READ:0;CHK:AA;SD:800;USB:8;LOOP:2，网上说UBOOT挂掉了，具体不知道怎么弄，制做什么启动卡，但BIN文件去哪找，有大神在吗？谢谢{znds12} 我也碰到了,天邑TY1208晶晨S905M-B,线刷不了啊总出错在1%什么读取镜像失败的。。、、连TTL就无限那些EMMC:0;READ:0;CHK:AA;SD:800;USB:8;LOOP:2，网上说UBOOT挂掉了，具体不知道怎么弄，制做什么启动卡，但BIN文件去哪找，有大神在吗？谢谢

然后停止不动........................
我的情况和你的情况差不多，可以刷机完成就是启动不了开机定屏。在另外一个盒子上面用编程器读取的EMC写的这个刷坏的盒子里面也是一样的情况。实在是搞不懂哪里不对了
