Serial port in Kindle PaperWhite 3
Hello my fellow kids,
I have a Kindle Paperwhite that I bought last year, with firmware 5.9.7 and a serial number G090 G1XX XXXX XXXX that according to your wiki is the Kindle PaperWhite 3 (2015) 7gen, WiFi Edition also called PW3 [1] These forums are very messy, but they contain very valuable information ... According to what I have read, in the version I am in, you can not jailbreak by Software, so the other option that I have found is to use a serial port , the problem is that, before opening my Kindle, I would like to know if my model has the option of a serial port and if it is the same installation that is discussed here [2] and here [3], I have thought of buying the "USB TTL Serial Cable 1.8V" model TTL-232RG-VREG1V8-WE, ¿it would work with my model? regards.

Reason: more specific with the model of my kindle |

USB to Serial cables are for PCs, Mac, Linux etc, anything with a host port (or a USB2Go) that already has serial over USB driver software. So some do work for some versions of Android phone/tablet (but not all adaptors nor all Android versions nor all Android gadgets).
Some Kindles have internal pads or connections for TTL serial (The DXG seems to have two!), often labelled on the PCB. I never heard of a USB serial adaptor working on a Kindle eInk eReader (needs driver and host mode), more likely NDIS over USB or Serial over USB would be supported as that works even with a "dumb" client only USB port. as that doesn't even need host mode, only |

Your [3] is the best for a new user. The Firmware version(s) mentioned and Hardware model(s) mentioned are only references to what was used during the development of the directions, they are not limitations. All devices (except the 2 Oasis models) since (and including) the K4 use the same process, with the same serial port pin-out, with changes to filenames only - with a possible exception of the filesystem layout of the PW4. So don't try to brick your new PW4 just yet. In [2] you will find links to electrical connection methods other than using "hot solder". If not experienced with that skill, check out the contents of those links. Last edited by knc1; 11-17-2018 at 11:42 AM. Reason: Typo'd reference |

I had thought only to make the connection by serial and install SSH to make it more comfortable so: 1- I need to do the jailbreak? 2- What advantages does it add? what cool things jailbreak add? 3- Do I need the jailbreak to install SSH? 4- If I have access by SSH, and update the Kindle firmware, do I still have access by SSH? 5- I have soldering experience, but I prefer not to weld anything to my Kindle, I had thought to do it like here [4], no problem no? Thanks! [4] - https://www.mobileread.com/forums/sh...06&postcount=1 |

1 - For everyone's sake, yes.
2 - Not trying to reinvent the wheel on your own. And making it easier for us to actually give you directions to follow, knowing that stuff will behave as expected later on. 3 - In short, yes. See. 1 & 2. Don't try to reinvent the wheel. 4 - In main, no, but you can reinstall it, in diags (if diags there is (OK on the PW3), and rp/crp was installed), yes.

5) Yes, that is one of the more popular, temporary, connection methods.
(Just don't use conductive foam - someone did and it took us forever to figure out what had gone wrong. ) |

I have already installed the serial cable, and the only thing that has come out is what you see in the attached image, I have tried again, and nothing comes out
What have I done wrong? |

That is called: "line noise".
Poor ground connection(s). |

EDIT: I have reassembled everything, through a breadboard, and now if I have seen the U-Boot log, but in half it has been put back with strange words, which is the best place to make land? (for now I have it on a screw) Last edited by mesblau; 11-21-2018 at 09:39 AM. |

That root password is only for the "Diags" system. The "Main" system has root login disabled. If you do not use "bootm 0xE41000" the system will boot to the "Main" system rather than the "Diags" system The password you have is for the "Diags" system there is no password for the "Main" system, which is what you chose to run by skipping the bootm ... part of the directions. All of this is fully described in the use of the serial port thread, try reading it and even better yet, follow it. |

When it reaches the step of 'Hit any key to stop autoboot', I press many keys to stop it but it does not respond, I've tried it like 10 times... do you think the problem is in my TX connection?
EDIT> problem in TX connection, now is working. Last edited by mesblau; 11-21-2018 at 01:26 PM. |
