準備工具:
1.十字螺絲刀、U盤、電腦;
2.購買RS232 TTL轉USB串口線(注:必須使用此型號),還要買“杜邦線”,這個可以直接問賣家;

4.下載putty:??putty.zip (280.1 KB)
5.下載沙發管家桌面(下載:http://app.shafa.com/apk/shafazhuomian.html)和 沙發管家(下載:http://www.offerng.com/)分別改名為“shafa1.apk”、“shafa2.apk”然后拷貝到U盤;
具體方法如下:
一、將機頂盒背面朝上,用螺絲刀擰下四個腳上的螺絲,擰開后拿下后蓋;

三、將TTL的驅動安裝好后后,右鍵我的電腦——屬性——設備管理器——端口——COM"X"(X就是最后位數字)——屬性——端口設置——改為“115200”——確定;

按圖中的順序設置即可,COM后面的數字按照自己電腦的數字輸入即可,設置完成選擇open,接著機頂盒通電開啟盒子,此時putty會開始跑代碼(注意順序:一定要先“Open”,再盒子開機通電,否則不跑碼);

五、輸入代碼前可以多按幾下回車,看到root@Hi3798MV100://#這串提示后開始輸入代碼:
1.start adbd
注釋:打開ADB
