Guys thanks for the tutorial, I have done everything to downgrade but dont understand step 11, install blue card exploit since I have never done that ( I did this all the very first time and never used Gateway before). Can someone point me on how to perform this "blue card exploit" ? Thanks in advance
EDIT: I referenced this site
http://www.dsgameruk.com/blog/things-to-do-when-set-up-the-gateway-3ds-card-on-3dsxl-version4-14-5/
One thing that bothers me is that the launcher.dat file is on the root of my 3ds internal SD card from when I did the Gateway 3.0 install before the downgrade files were released, I am assuming this can be overwritten without issues?
EDIT 2: I instead referenced this site

However when I went and clicked on the Deep Lab icon the 3ds complained that there was an error, and it will now power off.
EDIT: 3 Silly I searched this thread too specifically, once I entered blue card many of the same questions I asked here were asked, ignore this but feel free to chime in if its important, thanks.
EDIT4: Got it working, for those who may end up like myself, after your downgrade to 4.2 is successful, put the Gateway Blue card files into your micro SD card then place that into your blue gateway card. Put the blue gateway card into the DS (after a fresh reboot so your not in Gateway Mode but regular sysnand your fresh 4.2) then click on the Deep Lab icon and run the gateway installer, instructions here.
