Well, I've been on FW 10.2.0-28 U and i've had Homebrew for about 2 months. I replaced the Mashers Gridlauncher boot.3dsx with Smea's boot.3dsx file so i can use CTGP 7 (Mario kart 7 rom hack) before I updated. After the update was done I got a black screen, like it was off, but the blue light and wireless light were still on. I turned it off and back on but the top screen was still black as if turned off. I pressed the power button and I was taken to the normal power off screen so I pressed the Home button and it showed the transition screen to the home menu but it never got any further. It should be on 10.3.0-28 U unless 10.4 got released today. I can't tell because the Home menu doesn't show up. I had Homemenuhax installed, along with Ninjhax and Oothax. I'm charging it right now. Is this a result of using the Homebrew Launcher? I don't know where else to post this. I made this account just to post this thread. It also show the charging Light as well as the notification light such as Spotpass and the friend online signal.
