How-to obtain root access of New Basic Kindle (2014) FW5.6.0.1

[Rosomak]

Thanks a lot guys, appreciated.
So nooby version looks like this:

1. generate the password with kindletool or python
2. attach serial cable
3. Connect through software emulated terminal or whatnot, google said something about Kterm
4. reboot the kindle
5. Press "Enter" to stop the autoboot.
6. Go by the points from the top of the thread.

Well, kterm is a standard terminal program compiled to run on the Kindle., You run it with KUAL as a Kindle app.

What you want is e.g. minicom or typerterminal or somesuch -- for sending commands over a serial port interface, including setting the baud rate.

Does it work on 5.6.5?

Does what work on 5.6.5?

Can I use the root to change the serial number and MAC address?

Cheers,

We will not give you any assistance with a blacklisted Kindle, which is the only reason for wanting to change these.

[eschwartz]

Wouldn't help anyway -- the serial numbers are listed @Amazon, they will notice if you create a non-existent serial number, and they'll also notice if the same serial number exists in multiple locations -- they'll just blacklist that number too.

Yes -- anything is "possible", and actually getting access to the device's internals is the blatantly obvious first step...
... as HarryT said, we can't help you do that, though.

Hi there, I just connected to the serial interface of my Kindle KT2 and I'm able to see the diag login prompt, but the password i got with the python script doesn't allow me to login as root.

Welcome to Kindle!

[192_168_15_244] login: root
Password: 
Login incorrect
[192_168_15_244] login:

I also tried the two passwords that kindletool generated with my serial number (one is the same as the one generated by the python script), but they aren't working.. May I get some help? Thanks and sorry for my english.

Tells us how you reached what you think is the 'diag login' (most likely, you didn't).

[sguerrini97]

I connected to the serial console with the kindle powered on, then I selected "Settings -> Reboot" and I started to get things written on my screen. During the boot process I successfully managed to stop the autoboot.
Then, on the touch screen, I chose "(X) Exit", "(o) Reboot or disable diags" and then "Exit to login prompt". That's where I got the login prompt.

I can login with the framework user, so I think that's the diag login prompt..

This is what I get if I put the wrong password for three times:

[192_168_15_244] login: root
Password: 
Login incorrect
Unknown HZ value! (89) Assume 100.
process '/bin/sh /etc/getty-diags' (pid 1204) exited. Scheduling for restart.
starting pid 1214, tty '': '/bin/sh /etc/getty-diags'

Edit: I successfully logged in with "mario" password.. Whatever

From your description, you are still running the 'main' system.
Or, you might have been only summarizing what you did in general.

Perhaps you have heard (or read) the phrase:
"Garbage in, garbage out"
I can't see over your shoulder, so unless you tell all, I don't stand a chance to be of any help.

I'm sorry I wasn't able to explain the situation very well. As I said the kindle accepted "mario" as root password and I have jailbroken it with success, I appreciate your effort

That should not have been possible on a factory stock KT2.
(You could sign in as 'framework' but not 'root' with "mario" in the diags system.)

I received my KT2 on the first USA release date and documented the contents of the files that control logins based on that one, you may have a newer or different firmware.
(For the main filesystem only, not for the diags filesystem.)

Did you get that KT2 new, yourself? (not new as a gift)
Or has it passed through other hands between its sale and when you received it?

What you are reporting may be a very significant change in the firmware.
We really need to know about the details.

@knc1 I bought it in a local store here in Italy, new in the original box. It was on 5.6.5. I ran the update to 5.6.5 (yeah, same version) from the recovery menu before trying that password, I don't know if that matters. I changed the password of the rootfs immediatly, but I did not change anything on the diags partition as far as I can remember so I can share it if you want to have a look at it.

Edit:
Firmware version: Kindle 5.6.5 2730300038

There is the difference. Mine shipped still on 5.5.something.
(It still is, but I can't check, it is powered down and dissassembled.)
