Good day Oasis 1 owner!
Finally there is a guy! I know
I also happy to bring this tutorial to all of you.
Disclamer: I am not responsible for bricked devices. Good luck!
Before doing anything, I strongly recommend you should take a look at below instructions:
1.
Kindle Oasis 1 back cover removal from iFix
2.
Serial Jailbreaking your fw >= 5.6.x Kindle for Dummies
You'll need:
- A computer
- Your kindle oasis
- USB-TTL serial adapter
- Solder
- Tool to open your kindle
- Python
- PuTTY
- Be patient!
Ok. I believe you have understood basics of serial jailbreaking a kindle.
Let's move to the fun part.
Step 1: Discover kindle diag mode root password
I'm doing this tutorial in Windows environment.
Firstly, please install python from python.org
Then open windows command prompt, input below code
Code:
python
import hashlib
print("fiona%s"%hashlib.md5("your kindle serial number with no spaces and all capital letters\n".encode('utf-8')).hexdigest()[13:16])
Your kindle password should be like
fionaxxx, write it down somewhere.
Step 1.1: Connect kindle to the computer. Copy all files in the kindle-5.4-jailbreak.zip to kindle. You can find it in
Snapshot topic by NiLuJe (kindle-jailbreak-1.16.N-r17396.tar.xz)
Step 2: R̶i̶p̶ ̶y̶o̶u̶r̶ ̶d̶e̶v̶i̶c̶e̶ ̶a̶p̶a̶r̶t̶ Open the back cover to access to the mainboard.
If you look closely in the lower right of the display connection port, you'll see 3 tiny round copper connectors which are Tx, Rx and GND. But wait, you need to disconnect the battery first.
Now wire these connectors with any USB TTL adapter that you have.
Kindle Tx --- Rx
Kindle Rx --- Tx
Kindle GND --- GND (you can also connect with the screw as I do)
Step 3: Prepare the software
Connect to USB TTL adapter to computer.
Open Device Manager and set up variable like below
Open PuTYY and setup like this
Then press Open, leave the blank window as it is
Step 4: Jailbreaking!
OK. This is important. As soon as you reconnect the battery, the blank PuTYY window above will begin to display some text. Please press any key quickly to interupt the normal boot and to access uboot.
Now, input below code. It's quite different from original K5 instruction:
Code:
run bootcmd_FB
bootm 0xE41000
You're now access to the system diags:
Back to your kindle screen.
Choose
Reboot or Disable Diags
then
Exit to login prompt
On PuTYY screen, input username and password
login:
root
password:
fionaxxx (as you remember on the first step)
Edit the password file, input below code:
Code:
mkdir /tmp/main
mount /dev/mmcblk0p1 /tmp/main
vi /tmp/main/etc/passwd
on vi editor, use your arrow buttons to move the hightlight cursor to the character "
x"
Press
X to delete the
x character
Input
:w to save
Input
:q! to quit vi editor
Input
reboot to reboot kindle.
Let's the kindle fully boot to your familiar home screen.
On PuTTY windows, press Enter and login with root.
Input below commands to jailbreak:
Code:
cd /mnt/us
sh jb.sh
If you find the text ****JAILBREAK**** on your kindle screen,
Congratulation!
You also can create the folder name "update.bin.tmp.partial" on kindle to help prevent OTA update and protect the jailbreak.
Bonus. I'll help you install KUAL on your now jailbroken kindle.
You can find everything in
snapshot.
Copy KUAL-KDK-2.0.azw2 (KUAL) to document folder and Update_KUALBooklet_hotfix_44a61b6_install.bin (KUAL coplate) to the kindle root directory.
Update your kindle.
Now, you have KUAL and free to install other plug-in such as helper+, screensaver, KOreader, etc.
Thank NiLuJe, grant2 and other contributors. Your work have helped me a lot.
Cheer!
