Need some help with N3DS CFW

So I got a N3DS today it came with CN and GW

I backed up sysnand and formatted emunand however I can't get rei, cakes or rx to work

rei doesn't boot, cakes gives black screen after launching and sometimes doesn't even get that far, rx depending on build will install but after clicking a button to continue it just goes black screen, GW emunand is working fine however

I'd prefer to have some CFW rather then carry around a GW all time
