rxTools is the best CFW for o3DS/2DS:

Read the error. You need slot0x25keyx.bin on your SD.
You can find the file on google.

Actually i redownload it and it is not longer giving me the error. However, another problem come up. When I push Y to enter rxmode and screen just blank out black and i have to do a hard power off. My emunand was previously setup with gateway, would this cause issue?
