Screen Black after Firmware update

Fri Jul 13, 2018 7:04 pm

New problem, can no longer get a screen after the rainbow, I did some editing on the config file as what I searched "hdmi_drive=1

hdmi_force_hotplug=1" I get some text now as loading then no signal message from monitor :(

Thanks!

If you have SSH enabled you can login via SSH, edit /boot/config.txt and reboot.

If you have a keyboard attached to the Pi you can try a blind login and shutdown after hitting Control+Alt+F2 to open a CLI (or just Alt+F2 from Raspbian Lite with no GUI).

Otherwise, pull the power, hope you don't corrupt anything, and edit the file on your main PC.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

Explain what you mean by firmware update and how you did that and why?... Simple edits to a config file is not a firmware update.
Unless specified otherwise my response is based on the latest and fully updated Raspbian Stretch w/ Desktop OS.

Good idea using a video from FIVE YEARS ago, that's going to still work, not.
