The message means just what it says. The phone has detected that you installed or changed some system files that it doesn't like. And is exhorting you to go to a service center and let them return your phone to 100% stock.
We would know a lot more and could have given you a lot better advice had you provided basic and critical information such as which S5 model you have and exactly which files you tried to write to your phone. Since you didn't provide those crucial details, we have no idea what is really going on. Presumably you wrote the wrong firmware to the phone or botched a rooting process.
Without any details, all I could suggest is that you use the Odin software to write a 100% stock firmware file the phone, followed by a factory data reset. This will remove any user files or changes and should resolve the error message. Then you can redo whatever you were trying to do.. root, update, etc.

Flash a different kernel made for your device, that is also a kernel error. good luck.
Actually, you need to provide a little more info, like what base are you running and so on. Complete questions will yield complete results.

Could this also be an indication that somebody has injected wiretap/spyware software on your phone? Interestingly, I recently went through a separation and within a week following the separation, my phone began to lag (became very slow), would shut down spontaneously, had less memory space available (without any evident source for the cause of a memory reduction (and with a 64 gb SD card)), and on two occasions, producing this message with an exclamation point contained within a yellow triangle immediately after a spontaneous (not user initiated) reboot, and those reboots occurred with more than enough power to operate (one time at or around 50% and the other at 11%).
Also, soon after I noticed the issues with the phone, I received a T-Mobile "Emergency Security Update" notification. It was not mandatory. I proceeded with the update. Then, within a week thereafter, I received another, that not only stated that it was an Emergency Security Update, but was mandatory, and further provided notice that to ensure that my device had not been compromised, the security update was necessitated.
A question of interest on that note, is whether or not the breach (wiretap & spyware software - (vendors available on-line)), occurred only at the device level, or whether or not it modified the SIM. It would seem, if in any event, the above did occur, that a hard reset, probably three times over, and a new SIM would be in order, if for no other reason than diligence in trying to ensure the integrity of the device and SIM (privacy/protection).
My Phone: G Note 4 (32 GB Internal / 64 GB Ext.)
Any thoughts?
