Help! My R4 does weird!

Could you please help me?
While trying to fix WarioWare D.I.Y. everyone was talking about firmware. And because I didn't now which firmware was on my R4 so I downloaded the newest on the internet (1.18). But now my R4 doesn't work anymore in my ds. :(
I've seen some topics, but I don't know very much about all those things like firmware. Could someone tell me what to do?

then you have an R4 clone, not a real R4. You need to know which clone you have so you can get the right firmware for it.

Uh, in which sense do you mean "doesn't work anymore"?
Does it freeze on a certain moment?
Also, D.I.Y. has not gotten a fix for the R4 yet (I think).

That's not a real one.Then you need the R4 SDHC firmware. Not another R4's.Check here - http://www.linfoxdomain.com/nintendo/ds/
