升级包版本：v1.0.15

主芯片：Mstar， Cortex A9

虽然电视比较旧，但原理相通。

先解包MstarUpgrade.bin：

先下载解包工具mstar-bin-tool

命令：

unpack.py MstarUpgrade.bin

或

python unpack.py MstarUpgrade.bin

解包后的文件：

头部脚本（header_script）:

里面有升级的配置文件和一系列的mmc命令

自动读取、执行这些命令完成升级

这里主要对system.img进行修改、优化：

方法一：

用ROM助手打开system.img：

ROM编辑 – APK精简

这里列举出了系统内的所有app

勾选需要删除的

编辑权限：

1、在此可以修改文件或文件夹属性

2、添加新的文件或文件夹

此时可以将root用到的su(system/bin), superuser.apk(system/app)等文件放入相应的位置

点击“开始封装” ：
自动产生一个新的system.img

如果是增加app时需要注意system分区的剩余空间，不能超出：

方法二：
在linux系统（如ubuntu)中挂载后修改
命令：sudo mount -rw -t ext4 system.img sys

biren@ubuntu:~/downloads/new$ mkdir -p sys
biren@ubuntu:~/downloads/new$ sudo mount -rw -t ext4 system.img sys

查看system.img内容：

biren@ubuntu:~/downloads/new/sys$ ll
total 60
drwxr-xr-x 13 root root 4096 Jan 1 1970 ./
drwxrwxr-x 4 biren biren 4096 Jun 9 20:41 ../

drwxr-xr-x 2 root 2000 4096 Dec 16 2012 xbin/

修改。。。。。。
退出挂载:

biren@ubuntu:~/downloads/new$ sudo umount sys

用新的system.img替换MstarUpgrade.bin中原来的位置：

查看头脚本（Header_script）：
知道system.img在MstarUpgrade.bin的位置从e04000（含）到19e04000（不含）

用WinHex分别打开新的system.img及原MstarUpgrade.bin :
复制system.img所有二进制数据：

光标定位到MstarUpgrade.bin的e04000地址处
编辑 – 剪贴板数据 – 写入

保存数据。

更新到电视：

将MstarUpgrade.bin存入小于8G的U盘（fat32）根目录内
按住控制器上的开关机键不放
打开电视上的电源
等电源指示灯一闪一闪表示正在写入数据
。。。
写完后自动重启。
