My RaspPi 2B got some water on it and my SD card inside broke when I cleaned it.

I just bought a new one but it doesn't seem to boot now. I get no screen and the RJ45 slot doesn't blink up.

I used the official Raspberry PI OS Formatter (it's FAT32) and the Pi starts with a blinking green light but switches up to a solid green light after about 5 seconds. Sometimes the light disappears fully

What could be the problem? Model is the Pi 2 Model B
