为了提升康佳LED37R5200PDF电视的性能和用户体验，许多用户选择进行系统的精简和升级。在这一过程中，晨星Mstar芯片及其配套工具mstar-bin-tool发挥着重要作用。通过使用这些工具，用户可以便捷地对电视系统进行定制和优化，去除冗余功能，提高系统响应速度，甚至添加一些新功能。

1、配 置：

电视型号：LED37R5200PDF，6a800c
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。

2、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

5、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

6、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

康佳LED37R5200PDF电视精简升级 晨星Mstar与mstar-bin-tool使用指南

点击“开始封装” ：
自动产生一个新的system.img

康佳LED37R5200PDF电视精简升级 晨星Mstar与mstar-bin-tool使用指南

如果是增加app时需要注意system分区的剩余空间，不能超出：

康佳LED37R5200PDF电视精简升级 晨星Mstar与mstar-bin-tool使用指南

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

查看system.img内容：

  1. biren@ubuntu:~/downloads/new/sys$ ll
  2. total 60
  3. drwxr-xr-x 13 root  root  4096 Jan  1  1970 ./
  4. drwxrwxr-x  4 biren biren 4096 Jun  9 20:41 ../
  5. drwxr-xr-x  2 root  root  4096 Dec 16  2012 app/
  6. drwxr-xr-x  2 root   2000 4096 Dec 16  2012 bin/
  7. -rw-r--r--  1 root  root  1979 Dec 16  2012 build.prop
  8. drwxr-xr-x  9 root  root  4096 Dec 16  2012 etc/
  9. drwxr-xr-x  2 root  root  4096 Dec 16  2012 fonts/
  10. drwxr-xr-x  2 root  root  4096 Dec 16  2012 framework/
  11. drwxr-xr-x  8 root  root  8192 Dec 16  2012 lib/
  12. drwxr-xr-x  3 root  root  4096 Dec 16  2012 media/
  13. drwxr-xr-x  3 root  root  4096 Dec 16  2012 tts/
  14. drwxr-xr-x  8 root  root  4096 Dec 16  2012 usr/
  15. drwxr-xr-x  3 root   2000 4096 Dec 16  2012 vendor/
  16. drwxr-xr-x  2 root   2000 4096 Dec 16  2012 xbin/
复制代码

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）

康佳LED37R5200PDF电视精简升级 晨星Mstar与mstar-bin-tool使用指南

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：

康佳LED37R5200PDF电视精简升级 晨星Mstar与mstar-bin-tool使用指南

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

康佳LED37R5200PDF电视精简升级 晨星Mstar与mstar-bin-tool使用指南

康佳LED37R5200PDF电视精简升级 晨星Mstar与mstar-bin-tool使用指南

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。
