How to reset lock password?

Hello I recently got Odroid N2 with already installed coreelec. I set a lock password but now I cannot remember it.
Some forum posts suggest removing profiles.xml or editing it using ssh connection. I tried it some times but I always get the original profiles.xml (the one sith the password) back. And after reboot I get asked for lock password.
I also tried to pull the SD card and edit the files with my linux PC, but I cannot mount it rw…
How do I reset it? Is there a way to do it without reinstallation?

Not able to help you here, but just asking myself what’s the use of any password that can be easily removed/bypassed…
