Once your Raspberry Pi has booted, you will have root access. You can use the command passwd pi (if “pi” is your username) to reset the password. After changing the password, remove the init=/bin/sh line from the cmdline.txt file and then reinsert the SD card into your Raspberry Pi to reboot normally. This process will give you access to your Raspberry Pi again with a new password.

What if my Raspberry Pi is not appearing on the network?

If your Raspberry Pi is not appearing on the network, there are a few troubleshooting steps you can follow. First, ensure that the Raspberry Pi is powered on and that its network connections (wired or wireless) are properly configured. If using an Ethernet cable, check for a solid LED indicator, which indicates a successful connection. For Wi-Fi, ensure you’ve entered the correct network name (SSID) and password in the configuration file.

You may also want to check your router settings to confirm the DHCP (Dynamic Host Configuration Protocol) feature is enabled, which assigns IP addresses to devices on the network. If DHCP is working properly, and you still cannot find the Raspberry Pi, try connecting it directly to your PC or rebooting your router as a final step. This often resolves connectivity issues and helps your devices recognize each other on the network.
