Default [Q] Ink effect on Lockscreen with Finger

I want to make ink effect with my finger on lockscreen. I found this bu I don't know if its compatible with Exynos version (which I have) and I don't know how to return to stock lockscreen if something bad happens.

Or is there any xposed module that does this? It would be more convenient to just activate deactivate the module.

UPDATE: I tried the link, flashed it but it doesnt do anything on Exynos. Any help?
