HOW Reset A Forgotten Raspberry Pi Password

Pada raspberry PI 3 :saat awal boot tekan ctrl+alt+del+shift

edit cmdline.txt

dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

menjadi 

dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait init=/bin/sh

lalu reboot

saat CLI ketik:

mount -rw -o remount /

Lalu

passwd pi

lalu: ketik :

sync
exec /sbin/init

Lalu Shutdown Pi
sudo halt

Tekan lagi saat awal boot:

ctrl+alt+del+shift

edit  “cmdline.txt” file again and remove the “init=/bin/sh” yang telah ditambahkan di langkah 2

Lalu reboot  dan gunakan akun terbaru tadi....

====================

Pada raspberry PI 2 file  

cmdline.txt harus di edit via PC

nb penulisan di CLI bisa juga sbb:

mount -o remount,rw /
passwd pi
(enter a new password)
sync
exec /sbin/init
