I have a perfectly running Raspberry Pi 3 Model B, with a Raspbian Distribution on a 16 GB SD-Card. I connected a Screen with a HDMI-to-DVI Connector to it, a Mouse and Keyboard and I also have SSH access. Further I got a Kuman 3.5 Inch Touch-Display, which I want to use on it. I read myself through the Internet enough that I know I can't use the Screen and the HDMI-Screen simultaneously. So I connected the Screen to the right Pins, the Backlight already works. So I take the Drivers that are sent with it. Searched the one for my Distribution, extracted the Script onto my Raspberry Pi and launched it through./LCD-35 in the terminal. After a few seconds it Reboots and the Color-Test appears. The Screen for the NOOBS-Recovery-Mode appears, which I can still use, then a few seconds later:
---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)
I can unplug it, like I said, the color-test and the recovery and the same again, regardless of having the HDMI-Cable, the Display, USB-Mouse/Keyboard plugged in or not. Before I made a .img of my card so I can flash it again to have my old state, nonetheless, the LCD won't get to work through that.
Can you help me configuring the LCD? I already tried it 2 times this way, both times the same.
UPDATE: I installed a IMG of Raspbian sent with the Display, which worked, let's say 50 %. It worked as a mini-screen, but not more. The touch wouldn't work. I tried to calibrate it, read and did the instructions for my screen, but nothing helped. It's not the original problem but I'd still rather install it on a working system without the special Raspbian.
