最近拿到一个android设备,到手以后常规方法,直接用kingroot尝试root,但是一会儿再看发现设备自动关机了,这让我很奇怪,就再开了一次,提示如下
锁定
然后自动关机,再开机还是这样。那么似乎这个设备就不能使用了。这。。。
并且此设备并对外观方面防护比较严,只有一个开关机键。并没有办法进入各种暗黑模式
最后我在瞎猫碰死耗子的研究时发现,插上电源和usb数据线以后,开机进入了一个神奇的模式,该模式大概长这样
黑屏上显示这样一个充电标识,,然后我试了一下该模式下adb 居然可以用,我试着用adb install一个apk时居然发现无法安装,提示原因是:/data/local/tmp目录存在, 这引起了我的重视,我顺便看了一下发现sdcard也没有挂载。
而且目前加载的文件夹全是root权限才能使用的,那么我试着输入了一下su命令,得到如下响应,
xxxxx:/ $ su
[-] Connection to ui timed out
xxxxx:/ $
我百度了一下,网上比较靠谱的说法是kingroot卸载的问题,这里我可以确定这设备并没有卸载kingroot,他的检测也仅仅是执行su,判断su是否存在
但是su无法切换,shell用户又无法修改文件

这种情况下无法修改文件系统,那么这个设备是不是无法玩了,期待各位大神出点主意!ps得到如下结果
