Hello, this is my first post here, I hope it's in the right place.
So, here's the problem I have. I updated my rapberry pi 1b earlier today. The update erased my /boot/config.txt file and /boot/cmdline.txt files. Not that much of a problem, I can just rewrite them and I did. But now I get a problem I didn't had before. After the computer is finished booting, the perfectly good b/w composite output blinks and when it comes back it's now overscanned and I cannot see the text at the edge of the screen. There is also some text appearing after the blink, here's a link to the picture : https://cdn.discordapp.com/attachments/ ... 210120.jpg
Any idea as to why that happens and what I can do to make that stop happening ? I also cannot use HDMI, so that's out of the question.
