Hacking Problem with installing CFW

[Mavese]

Okay so I was in the process of installing CFW and following the guide at 3ds.guide. I followed all the steps and after I selected "show nand or user string in system settings" in the configuring luma3ds. I rebooted my 3ds. I tried going back into the hombrew launcher and it crashed. Now when I press the power button it will flash on then off once.Nothing comes on the screens and it makes no noise.It seems like if I have an sd card in, it will light up slightly longer and then turn off. My ofw is 11.2.0.35U Any help please?

Flashing on then off means it can't find boot.firm. Check you have it on your SD card, and if you do, try a different SD card.

Okay so I tried a brand new sdcard. The first time I tried to turn it on it still just flashed.So I took out the sdcard and put it back in. Now the blue power light will stay on but nothing appears on screen. Like not even a black screen just nothing.

Wow okay I noticed the boot.firm wasn't on the new sd. I feel like an idiot. But yeah I guess it was the sdcard. Thanks for the help.
