Suddenly Can't Authenticate?

If you find that the originally normal FolkPatch suddenly fails authentication, or prompts that the kernel patch is not active, don't rush to doubt life. Usually, this is not because FolkPatch's code ran away by itself, but because you installed some self-proclaimed "advanced" automated exclusion modules.
Why Does It Fail?
Many users blindly install various Magisk/KSU modules for the sake of "passing environment". Among these modules, there is a type that is extremely "diligent"; they will automatically scan and exclude all injection behaviors they deem "wrong package name".
1. Friendly Fire by "Allies"
Some modules under the banner of "Fully Automatic Detection Bypass" will indiscriminately blacklist all third-party injection processes. Unfortunately, FolkPatch's core injection logic is often at the top of their exclusion list.
- Phenomenon: You installed an exclusion module to pass an irrelevant banking app check, resulting in FolkPatch being completely blocked by the system.
- Irony: You successfully "passed" the check, but you may have also successfully turned your device into a glowing brick that can only be looked at but not used (at least at the FolkPatch functional level).
2. Blind Pursuit of "Purity"
Some people pursue the so-called "ultimate pure environment", wishing to hide all Root traces in a dimensional pocket.
- Truth: FolkPatch's authentication requires deep communication with the kernel patch. If you "exclude" FolkPatch, how can it prove its identity?
- Suggestion: Before installing any module that claims "automatic exclusion" or "deep hiding", please use your brain first and think about what this module is actually excluding.
Solution (If You Are Not Dizzy Yet)
- Check Module List: Recall, before your authentication failed, did you install some "XX Detection Bypass Enhanced Edition" or "XX Fully Automatic Hiding" again?
- Disable Exclusion Modules: Try disabling these modules and restarting. If FolkPatch returns to normal, then congratulations, you found that "insider".
- Precise Configuration: If you must use these modules, please manually whitelist FolkPatch related processes in their whitelist or exclusion rules.
注
"Not Installed" After Reinstalling the Manager?
FolkPatch's signature verification mechanism works by having the kernel actively search for the manager to authenticate at boot time. This means if you uninstall the manager and reinstall it, the manager showing "not installed" or "authentication failed" is normal behavior, because the kernel still holds the UID of the old manager.
Solution: Just restart your device. After reboot, the kernel will re-authenticate with the new manager.
Reminder
Passing the environment is for a better user experience, not to "pass" away the truly useful functions. If you don't even know what you are hiding, it is recommended to maintain the status quo and stop messing with those "fairy modules" of unknown origin, and don't blindly "pass" without knowing the true meaning of excluding injection.
