it should work fine , maybe you need to specify the extention of the file you want to open

Hi @_insidious, are the (path) is a variable? Just merged it instead of using f-string:

io.open(f'/sys/{paths}', 'rb'):read('*a') --Fstring: x
io.open('/sys/' .. paths, 'rb'):read('*a')

• - Can you include some Logs file?
• - Also check for Game Guardian permissions, both on Application and Root level
• - Maybe there's some interference for Game Guardian accessing /sys. Could be Samsung Knox or something.
• - On Newer Android (12-13) there's some Internal changes regarding permissions level and Processes. More likely is this.

Try to modify some Configuration:

su
setenforce 0 --Permissive SELinux
mount -o ro,remount /sys --/sys as Read-Only

Or if you're using Magisk, try to modify the Context:

mount -o rw,remount /system --/system as Read Write
u:object_r:magisk_file:s0 --Duplicate any Magisk Path and add this Context along with it (in the end) on /system/sepolicy/file_contexts

the code works in my nox but not in my phone, i just need to do this without any external lib, just by running gameguardian
