Kindle PW3 5.9.4 Jailbreak
Hi I wanted to create this post to see what the status of Kindle PW3 5.9.4 Jailbreak was.
I read the forum post asking about Kindle PW3 5.9.2 Jailbreak but wanted to create a new thread as per the recommendation of knc1. Hope I am following the forum rules |

As knc1 noted, threads are free here. To the best of my understanding there is currently no software jailbreak for this version of the firmware. So your only option at this point is serial port jailbreak. Your model is one of those where this can be done, unlike the Oasis models where the location of the serial port has yet to be determined.
Performing a serial port jailbreak requires opening the unit to gain access to tiny, delicate connections on the system board. You also require the proper serial hardware and software on your computer system to work with the serial connection. Using the wrong hardware or insufficient care can result in a damaged or destroyed unit. Should you have the skills and tools to do it, look at the thread on serial jailbreaking.

It looks pretty crazy, but I might give it a shot if I have the time. |

There might be a software only solution in the future,but it depends upon someone locating a vulnerability that the firmware writers missed that can be exploited to allow the jailbreak to be installed. Thus far none has been found for the later firmware releases. Dave |

Confirming that for PaperWhite 3, firmware 5.9.4, the serial jailbraking works more-less as described on the mentioned thread: https://www.mobileread.com/forums/sh...d.php?t=267541
For serial connection, I used these: https://www.ebay.es/itm/FT232RL-FTDI...kAAOSwLF1X~KFv and https://www.ebay.es/itm/Logic-Level-...YAAOSwv0tVV0~4 For some reason the FTDI chip did not work over a long usb cable, but did work when directly plugged into the PC. All the drivers worked automatically (win 8). Putty connected as described. bootm 0xE41000 booted into diagnostics however, there were different menus. what worked to go into login menu was typing "exit login" login root and password generated by python and serial number were good. This part worked, but I needed to change mmcblk0p1 to mmcblk0p2, and I think I typed mntroot rw before. Not sure. Code:
mkdir /tmp/main mount /dev/mmcblk0p1 /tmp/main vi /tmp/main/etc/passwd Now, I'm having problems running KUAL. Please, help. I've tried copying the azw2 file to documents. Not shown in my library. I've tried with ;log mrpi, I think correctly, but nothing happens. |

Here is the KUAL booklet installer that can be run via Update Your Kindle menu: https://www.mobileread.com/forums/sh...21#post3613021 And here is the patch if the KUAL start screen is blank: https://www.mobileread.com/forums/sh...d.php?t=294765 Last edited by hius07; 03-14-2018 at 04:53 AM. |

Modifying the "main" system is the entire point of all proceeding steps. If you have any problems, try following the directions next time. PS: You must use the KUAL booklet, not the KUAL document, when running any 5.9.* firmware version. Try reading those directions (the ones packed with KUAL) also. You will have a lot less trouble if you read and follow the directions rather than make things up as you go along. Last edited by knc1; 03-14-2018 at 09:36 AM. |

Yep. My bad. I redid the jailbreak procedure, and it produced a successful jailbrake message. In my defense, there was a slight difference in the menu exiting procedure (I needed to type 'exit login') and before changing the password file I needed to type "mntroot rw". After that, all good.
I've struggled with the KUAL installation, and it worked by copying the * nomax* bin file to the root of the usb, and then clicking update my kindle. (I was trying to copy that file to the mrpackages). Thank you both :top: |

Works on Paperwhite 2 as well on 5.9.4

I can confirm that the jailbreak works on a Kindle Paperwhite 2 on 5.9.4 firmware. I agree that you need to type "mntroot rw" prior to launching the jailbreak.sh script. I used the Ftdi TTL-232RG-VREG1V8-WE USB to TTL cable. I purchased it from Amazon. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 One thing I'd like to add is that the serial port connection is very tiny on the paperwhite 2. Even though I was very careful, I ended up ripping off the pads of the the RX and TX connections. Thankfully on the otherside of the board, pins TM800 and TM801 are the same RX and TX connections. I still had to solder in the ground cable to the ground on the serial port connection to make this work. Also, I WAS able to install the Kual booklet successfully and also install the backdoorlock using the KUAL installer. (To prevent Amazon from auto upgrading the firmware). I would be happy to provide pictures if anyone wants to see how I soldered the connections. |

You are writing about a PW2 in a thread dedicated to the PW3.
Thread hijacking only makes what you post impossible to find later. The serial port pinout and connector pad has been identical since the K4 (with the exception of the two Oasis models). The "backdoor lock" has not worked for several years. You really should do what is recommended in our jail break thread(s) to prevent OTA updates. Last edited by knc1; 04-16-2018 at 08:49 AM. |

With that being said, if you could provide a link or two on how to best block OTA updates, it would be appreciated. My research on the internet led me to believe that the backdoorlock was the best way to block OTA updates. Based upon what you said, I am clearly in error. |

In other words, what's the state of Kindle software jailbreaking? Dead in the water, or is there hope? |

However It is definitely worth it! I'm so happy to have KUAL back, and access to kterm. I have a script that I wrote to delete those annoying ads (Special Offers), and without access to kterm (or a serial port putty connection), there was no way to delete the ads.
