I have tried everything except reinstalling RetroPie, because I want to try every last thing, before I spend hours reinstalling all my games and so on. Here it goes:
I bought a screen from AliExpress: http://www.aliexpress.com/item/Pi/32378324026.html - I immediately plugged it in, and now the screen lights up (but it's white).
I followed all the guides I could find, but generally all I had to do was:
Under Advanced Options:
Overscan: disable.
Device Tree: enable.
SPI: enable and load kernel module by default.
Audio: force 3.5mm headphone jack (since HDMI will be disconnected later).
After doing all this, it said:
modprobe: ERROR: could not insert 'spi_bcm2708': No such device
So I read a ton of sites saying I could blacklist 2708 and use 2835 instead, but after trying all the possible things inside /boot/cmdline.txt and all kind of files, but after rebooting literally 30 times, I still haven't gotten the screen to turn on with something.
What can I do? I followed a bunch of guides:
https://learn.adafruit.com/running-opengl-based-games-and-emulators-on-adafruit-pitft-displays/retropie-setup
http://www.circuitbasics.com/setup-lcd-touchscreen-raspberry-pi/
http://diyhacking.com/raspberry-pi-touchscreen-lcd-tutorial/
And so on. Nothing works. What can I do? How can I check if SPI is enabled and I can actually use the screen? I'm really stuck and I would love some help.
Thanks
