iSu [V7.6][5.1+] Simple app to deactivate activate LineageOS SU at will

I know that there is many tools apps etc to disable or hide SU.
I decide to make this just because those did't work on my device back in 2016 and or CyanogenMod/LineageOS ROM that I use, so I assume this happens to other in CyanogenMod/LineageOS users too, I start this thread and made this app that can help to pass a safety net test on any rooted device (hide SU only when using Lineage add on SU) as it is no longer just a SU hider app is little more.
​

• This is only to CyanogenMod/LineageOS SU binary aka CM-SU, the CM-SU only works with CyanogenMod/LineageOS ROM's and ROM that use they source code as base
• That can be Download from Lineageos download page click here to see
• No it doesn't work with SUPERSU or any other SU that is not base on CM-SU
• No it doesn't support Xposed Hide, if you use Xposed you can't pass safety net with CM-SU.
• No it doesn't support AB devices (devices with two system partition) that can't be mounted as rw dynamically in android.

• read Installation instructions, download Folder with instructions on the bottom of the post
• Download and Install the app as a normal app, if you wanna the full app support, use a ROM with the supported SU version (CM-SU), download Folder with instructions on the bottom of the post
• if on Marshmallow or Lollipop flash the zip (iSu_kernel_Reboot_Support), download Folder with instructions on the bottom of the post
• Learn how to use the app, below instructions

• Su deactivated (demanding)
• SELinux enforced (demanding)
• Android debugging deactivated (not demanding for all devices)
• Props known props or special props can't have a red warning (demanding)

Below are some samples of fails or pass:
PASS

*Android debugging only affects some devices, disable if you don't need it.
*In props if there is props with a red warning that may be the reason of the fail if SU and SELinux is set as the above.

If you have SU active you will always fail
FAIL everything

*Fail because SU is Activated

If you have SU deactivate you will not always pass
FAIL everything 2

*Fail because SELinux is in Permissive

If you have SU and SELinux on a correct position you may not always PASS, because some props cause fail of ctsProfile
FAIL ctsProfile

*The above fail because ro.boot.verifiedbootstate
*Some props may or may not cause full FAILS or a FAIL of ctsProfile

The app is divided in 5 tabs (Checks, Controls, Monitor, Props and settings), plus widgets and tiles, bellow a detailed description:
Checks

Basic information about the application, the main start tab if it show a red warning on the SU state options because yours current SU is not supported and the app will work with limited functionality.

• Update, Check for iSu updates
• Safety Net test, Let the user try the safety net status, in case of fail it will tell what fail and current SU, SELinux and ADB state as those if on wrong position will cause the fail

Awesome work! Glad I accidentally stumbled on to this. Magisk stopped working to hide root but this is still good. Woot!:good:


edit: In your isu.sh, shouldn't the end of the script be:

Code:

mount -o ro,remount /system
# instead of
umount /system;

edit 2: For anyone who wants to build their device/kernel with support baked in, so they don't have to patch, I distilled the changes down from your git and created this patch:
https://github.com/blastagator/cm_d...mmit/79118c58fee32d10aa75464ee95751c7e6b8fdc5
This should be a good basis for others to manually patch in support. Working well on my custom cm13 builds.

Yeah, I did that, but dunno if was because of that it failed, or not... I'm fine for now, reverting it whenever I close the game, I put su back Maybe it was because I was trying to cheat on PoGO, and didn't work with Fly GPS, and uninstalling the app in a bad way provoked that I will do a nandroid and try again

Would there be anyway to automatically trigger this for certain apps? This is the first root hiding method i've found that actually tricks Barclays Mobile Banking. Great work
