As the title says, have tried seven knights with the new version of GG but still getting Security Alert (code:5) error that forcefully closes the game. Is this related to ptrace or is this a different security implemented by netmarble?
So some of you (just like me) have already noticed that modern and up to date android kernels started implementing Yama's third level that prevents Game Guardian to work. It's only the question of time until Android developers at Google's start hard coding this wondeful feature of Linux.
"What is Yama?" one might ask. Well in short Yama is an android security module. You can read about it here in detail.
Once it is set to 3 you can't change it sadly. But you can set it to 0 temporarily by the following command using it in root mode with an Linux terminal emulator.
su echo 0 > /proc/sys/kernel/yama/ptrace_scope That's it. Now you can use Game Guardian just like before on your Yama hardened android device. Works until reboot then you have to enter the command line again. Have fun!
