I need first to know that password before doing something useful
Actually I found the way which solves the issue without opening kindle and knowing password:
For that you need rootfs image I will send you the link through message.
And you need any linux. Example Ubuntu.
Than you need:
Go to recovery menu (Hold sleep button for 15 seconds, after release sleep button and hold home button or press multiple time in my case to go recovery menu)
In recovery mode press (E 3) button.
Connect kindle to the usb port you will see Usb connected.
In terminal (console) write:
this will list all drives on the computers
Look for a 3.65 GB (can try df -kh as well) drive and make sure it is the Kindle. Remember it's device id. It should be something like /dev/sdc or /dev/sdd it will be last in the list.
dd if=/path/to/rootfs.img of=/dev/sdd1 bs=1024
Wait till this command finishes and Press (R 4)
Kindle will reboot and starts.
Make Factory Reset from settings and thats all.
This should help in you case.
