Problem with R4

So, I have just changed my R4 cause my last one didn't work. All the games freeze at the beggining. But, my new R4 (that's exactly the same as the old one) can't run the games too. Is it possible?? I have tried a several things, like patched games, desactivate cheat in game and reset.. But it still don´t work. Any help?
This is my flashcard: R4 Infinity Dual Core (2014)

Hopefully, this will help you out.

I'm not going to buy a new one :/ But thanks anyway

Crappy clone cards, learn by it.. don't do there in future!.
