富士通F-03G安卓平板完整ROOT
最近收了个古早的安卓平板,由于配置还行,尚感觉堪用。但由于系统自带垃圾软件太多,故想办法直接ROOT了它
基于CVE-2017-8890编写ARM32移植及构造ROP Chain
设备信息
SoC:QCOM MSM8974
RAM:2GB
Flash:64GB
Android版本:4.4.4
Linux版本:3.4.0
软件版本:V13R29B(可能兼容:V11R27F/V12R28B)

由于该设备仅用于测试用途,故未安装权限管理器,在此使用给Settings添加语言作为ROOT成功之范例
注意
由于富士通使用私有的LSM进行保护内核功能,请在使用exp提权之后,直接insmod LSM_Disabler.ko,如Shell无任何返回(于Dmesg会返回<!><LSM_Disabler>SUCCESS),再执行rmmod lsm_disabler即可完整解除保护
感谢
thinkycx提供的CVE-2017-8890Exploit代码以及实现思路
sir I have this tablet and want to root it but i am new to rooting so i do not know how to use this Exp file and also this lsm_disabler_new.ko confusing me can you little explain this
thanks
1.Use adb to push those two files into /data/local/tmp.
2.Give permission in rwxrwxrwx to those two files.
3.Try to run ./exp in shell. If it success, you will get # in shell. If failed,hold VOL+/- and Power to Hard Restart and try again.
4.Insmod LSM_Disabler and Rmmod it.
5.Enjoy it!
