It should now look like:

Then the editor should be like this:

Dwc_otg.lpm_enable=0 console=ttyama0,115200 kgdboc=ttyama0,115200 console=tty1 root=/dev/mmcblk0p2 ROOTFSTYPE=EXT4 Elevator=deadline rootwait init=/bin/sh

Step 3-Reset Password

Insert the card into a Pi which is connected to a monitor and keyboard. Power up the Pi. There May is a delay but you should is presented with a flashing cursor.

Insert the SD card into the raspberry pie (we need to connect the monitor and keyboard here). Turn on the raspberry pie and expect to wait a while before displaying a flashing cursor.

The Pi would continue to boot with the normal command line prompt.

The raspberry pie will continue to boot.

Shutdown the Pi and power it off.

Turn off the raspberry pie and power off.

sudo halt

Step 4–edit Cmdline.txt

Step fourth-Edit cmdline.txt text

Using the PC edit the "cmdline.txt" file again and remove the "init=/bin/sh" text you added in step 2.

Edit this text again with your computer: Delete the last data we added in step two

You can now return the SD card to your Pi, reboot and use the new password.

Now you can insert the SD card into your raspberry pie, and start again to use the new password.
