Hardware Hardmod help, blue screen doesnt show on boot

[louslyness]

Hi, I have recently had a brick in my 2DS system and decided to do a hardmod on the console as I had a Nand backup a year back. Though since the brick I can turn on the system but it shows just a dead black screen. I've soldered all the points (CLK,GND,CMD,DAT0) and to my microSD adapter; problem is that when i've done this it turns off after 3 seconds after i've pressed the power button. No blue boot screen either when inserted into the my Transcend reader as well. Would be glad for any help or suggestions as had been scratching my head from this one for a couple of days. (could it be the sd adapter? or do only some work?) Thanks.
