Upgraded my o3dsxl to 188.8.131.52U from 4.2u which was using rxtools and ds profile. Everything went ok and created an emunand and installed menuhax as wanted a fresh install of everthing. After doing so every cfw I have tried just gives a black screen. Sysnand runs fine if I let it boot and can run hbl by pressing L on booting but have tried every cfw out there and just get a black screen. Luma does give me the setup menu but just a black screen afterwards. Did the same to a friends before and worked fine.
