TVPad 4 Firmware
      1.文件下载后不要解压，在电脑上把它放进U盘或者SD卡根目录，注意：U盘或SD卡必须纯净没有其它文件，最好先格式化。
      2.U盘/SD卡插入TVPAD4盒子，TVPAD4盒子能自动识别U盤SD卡，在介面中会显示更新屏幕。如果没有自动识别，在系统设置/系统升级中选择U盘或SD卡升级。
      3.用遥控器输入： 200981811   随后盒子开始系统更新，此期间请勿断电。
      4.升级完成后，首次开机时间较长、大约在5-10分钟，用户在此期间请勿断电。
      5.设置网络自动检测，不再需要设置DNS。
      6. 此时，系统自带的app市场可能是空的，需要从外部导入apps。

Firmware升级后，需要重新安装apps，请下载安装TVPad 4 apps文件包，在电脑上解压（必须的），复制到U盘根目录，插入盒子，开机启动后，进入系统自带的app市场，看看是不是几十个apps都回来了？按你的需要依次点击安装就可以了。如果市场里还是空的，检查你的U盘，是不是2.0？如果是3 .0 那就不行，换成2.0 ，再复制apps，重复上面的操作。还是不行的话，试试选择外部存储U盘，点击分别安装apps，这个行不行？我不能确定。注意：不能使用SD卡，盒子不适用SD卡安装。
