天猫魔盒7C青春版system.img分区镜像如何替换泰坦桌面

15751885765

天猫魔盒7C青春版是全志313H的处理器，安卓10的阿里云系统，由于系统的泰坦桌面广告多，所有的视频都要会员，非常垃圾。所以想要安装第三方桌面，然后禁用原系统自带的泰坦桌面，当把自带的泰坦桌面禁用或者是删除后，开机无法进入桌面，多次尝试，依旧没有解决办法。猜测一，系统通过代码设置了开机强制检测泰坦桌面，系统如果发现泰坦桌面被卸载或者禁用，就无法开机，黑屏，无显示，提前安装的当贝桌面也不会做为替补桌面进而启动。破局的方法只能从代码的层面进行修改，可是本人小白，并不知代码修改方法，苦思无果，我会在末尾添加sys分区的镜像下载地址，感谢有能力的大佬提供帮助。

猜测二 ，第三方桌面要有系统权限的签名才能启动，要想从网络上获得天猫云系统官方的内部签名工具几乎不可能，现在的思路是根据从系统内部获得泰坦桌面APP提取出签名信息，逆向出可用的签名工具,对我而言想，这个方法依旧存在很大的难度，可以说完全没有思路。如果大佬了解这些知识，可以给个提示。

当然，如果你有其他的办法，可以留言帮助分享，齐心共力解决

你的方法是用假的泰坦桌面替换原来系统桌面，通过欺骗系统的方式打开第三方桌面，还修改了prob几处，没有效果。这种修改，因为原系统桌面被删除，遥控器关机后无法使用遥控器再开机，只有拔插电源才可以开机，无法遥控器开机这才是主要要解决的问题。
使用遥控器开机时，指示灯亮了一下就熄灭了，像是检测到原泰坦被删，验证不过，自动关机一样。电视端无视频影像输出，显示黑屏，开机失败一样，不知道是什么原因。
网上找的资料说是要反编译修改第一种方法：反编译framework.jar文件第二种方法;反编译系统文件service.jar文件
还有你删除aliguide是负责开机向导的，匹配遥控用的，天猫系列的魔盒都是有这个app,如果把他删除了就无法匹配遥控器了，而且他也不会影响到遥控器开机。 还有osupdate负责系统升级，从之前技凡制作天猫的固件中可以看到这个软件并没有被删除，也不会影响开机。
我想影响遥控器开机应该是另有原因。

只可以通过拔插电源线才可以开机，遥控器可关机，但遥控器不可以开机

现在主要解决是问题是遥控器开机，你修改的几处并没有效果。通过欺骗系统的方式这能拔插电源可以用，遥控器无法使用。只用原系统桌面不被删除的情况下才可以做到遥控器开关机。

这是网上找的修改固件不开机apk验证解决办法，需要反编译修改https://blog.csdn.net/u011283906/article/details/131416024

会不会与product和vendor分区有关系
