How-to obtain root access of New Basic Kindle (2014) FW5.6.0.1
#1  hondamarlboro 10-05-2014, 09:38 AM
Successfully obtained with following steps:

1. Open the back panel and get serial connections where printed "SERIAL DEBUG" Tx, Rx, GND (from L to R). I used "FTDI Basic Breakout - 3.3V" at hand with power supply from USB port
2. Get your password with Python script:
Code
% python -c 'import hashlib,sys;print "fiona%s" % hashlib.md5("%s\n" % sys.argv[1]).hexdigest()[13:16]' YOUR_SERIAL_NUMBER
3. Reboot Kindle and stop autoboot, then enter into uboot mode
4. Run 'bootm 0xE41000' command
5. Tap 'Exit' and 'Reboot or Disable Diags', then 'Exit to login prompt' on the screen of Kindle
6. Login as 'root' with your password generated by Python script
7. Mount filesystem and edit password
Code
# mount /dev/mmcblk0p1 /mnt/mmc
8. Reboot and enjoy!

Thanks for the info and pictures.

What are the first 4 characters of your Kindle's serial number?
Please, just the first 4.

PS: If you have a choice, use a 1.8v serial interface device.
The Kindle **might** tolerate 3.3v but it is 1.8v interface.

@hondamarlboro: Kudos!

I guess this is the moment we start begging for a rootfs dump? .

** Thanks **

A model (and a motherboard) we have not seen here before.

Is this model being sold in Japan?
Does it have a front lighted screen? (one of the PW* series)
Does it have 4G of flash?

Why?
So we can add it to our model table:

Dry-coded handling of it in KindleTool, I'll take a better look at it when I have more time .

Thanks again !

Ah, So

A touch screen replacement for the K4 in the model line-up.
It almost had to happen, they have been making the K4 for the "least cost" end of the product line for a long time now.

Link also claims "twice the book storage" - so the USA one must be 4GB also.

Also claimed: 20% faster processor - must also be an i.MX6 machine (like the PW2).

I can see they are building on a newer kernel (3.0.35 - released 17-Jun-2012).

Could you do a capture of the output of:
cat /proc/cpuinfo
for us?

Thanks for the USA link -
It is also showing me a "Kindle Voyage" link (new, top of line).

- - - - - -

Any USA dweller out there with more money than common sense want to throw $300 towards Amazon, buy a Kindle Voyage (3G+WiFi, no S/O) and tear it apart for us?
(Don't forget the not-included charger.)

I made suggestions for prefixs on the two 2014 models, see:

And before anyone asks with a crazy idea of downgrading to a JB-friendly PW2 Firmware: big nope.

Code
UPDATE_ERROR_DOWNGRADE_ATTACK=0xC
'ATTACK'. Why so serious, lab126? .
