My PiTFT was working fine, with the custom image flashed on the SD Card. But for downloading programs, they say to run
sudo apt-get upgrade and
sudo apt-get update. I do this, then reboot, now I get a white underscore in the upper-left corner. I ssh into the Pi and run
sudo apt-get install raspberrypi-kernel=1.20161027-1. Then I reboot again and it boots up only showing a white screen. Now I can't SSH into it anymore.
I am using a Pi 3 3.5" TFT
