康佳使用RTD2995D主芯片的4K网络电视主板EMMC坏的比较多，换EMMC后要用编程器写引导后再用U盘升级，还有一部分U盘升级失败导致不能再U盘升级的电视也可以写引导后再U盘升级！此升级方法已有不少教程，但还有师傅在群里问怎样使用，刚好修到这个平台的主板并实际操作了一下，本帖就来讲一下在线写RTD2995D平台EMMC引导程序方法和U盘升级方法！并上传使用过的软件和引导数据。



编程器要接主板上专用升级接口，不能用VGA口，用VGA口写到百分百之后会提示刻录失败，接好后先用打印信息试联机，打印信息设置115200 线序 12X15



升级前需先下载使用软件和引导程序
百度网盘下载地址链接：https://pan.baidu.com/s/104UH45DFVzd1PsCJQI3V0Q 提取码：pslq
下载解压后按下面照片设置和使用软件软件






写完引导后主板断电，把装有install文件U盘升级数据的U盘插电视上，打开SecureCRT串口打印软件。

SecureCRT串口打印软件没设置过的按下面帖子设置
用RT809编程器代替升级小板升级创维8R和8A机芯及其它网络电视升级工装设置方法
然后按住电脑键盘上的TAB键，主板通电3--5秒后放开，进入升级状态等升级完成即可。


可以正常升级的主板：程序放U盘按住电视音量+开机即可升级，单U盘升级升级不了时可以用此方法，此写引导方法RT809F和RT809H编程器JT1199编程器通用，也可以用RT809H直接写备份的EMMC数据。
