That experimental flasher wasn't even out when I wrote that comment.... So at the time it was true.The threads that appear every day are from reading 3ds.guide, as the single system 3ds guide provides a non-working flasher, and I have to redirect them to the working (albeit experimental) flasher.
The experimental flasher has had about 20-25 confirmed reports of it working, and the only "bricks" I've seen were with the WiFi flashcarts, NOT the Gold Pro and the Dual-Core.
