I've left my Raspberry PI 4 Model B on a shelf for quite a while but now that I finally figured out what I wanted to do with it, I can't get it to work at all. I've used the
rpi-imager from my Linux machine to flash the SD card with fresh installation of Raspbian, after inserting the card in and plugging the PI, it immediately shown a red light and after a few milliseconds, the green light quickly flashed once, then it just stayed red and nothing was happening.
Any idea what could be causing this? I assume the PI is dead but I wanted to ask just to make sure,
I was looking for an answer to this problem before asking, but all I could find was a question on this stackexchange with answer to use a newer software >2013 which isn't very helpful, someone also pointed out that it could be because of the power supply didn't have high enough voltage (or because the voltage was too high), however I'm using the official power supply so I'm pretty sure that can't be it.
