I was getting only a black screen, so I read posts about what others did and followed suit on my MAG 254. I am now stuck with TFTP mode, the blue screen and only tftp loading...... I have changed the boot setting to NAND and NAND 2, even back to DHCP with no results. I have tried a factory reset but it goes back to tftp loading at the end.....I have tried everything, I think......Help????
