sorry mate...be patient....xD
I can't find that "sticky" thread...can you link it here please? EDIT: You mean this thread? If so yes, there is a serial port on the left side (looking the kindle from the front) but how can i know if it's working or not? I guess i have to build / buy a tool/cable to use that serial port isn't it??? Last edited by Tommyxx84; 05-06-2016 at 05:44 AM. |

Ok boys....
I built my serial to usb adaptor... [Oversized image removed by moderator] stating that apart the blue wire that is the only one that does not match the usb cable colors (white <-> white, black <-> black, red <-> red, green <-> blue), what's the correct position for them into the serial connector? Currently they are just in there to check how solid was to connection so...random order... [Oversized image removed by moderator] the connection is pretty solid, but i'll tape them down to the mo.bo. anyway to be able to turn the device face up without problems.... I guess that once this is done, i'm ready to follow your "orders" ![]() ![]() Last edited by eschwartz; 05-07-2016 at 10:41 PM. |

Now that you have your colored wires connected to the K3 in "random order" (as you said), do not plug it in. Figure out which wires carry what signals, and match them to the K3 serial port pinout at the links provided. Then, if the voltage levels are correct and the wires are connected with appropriate signal connections, it should work (regardless of wire colors). ![]() Last edited by geekmaster; 05-07-2016 at 12:10 AM. |

Obviously i'm not going to plug it until i know that wires are set correctly.
The usb cable wires, as known, are: WHITE: USB DATA+ GREEN (blu wire in my case): USB DATA- RED: +5V BLACK: GND Based on this Pinout: I am doing this from memory, so it might not be correct. It is probably documented in mobileread along with the connector layout for a circuit board. On the kindle models that I have examined, the serial port layouts were designed so that it is okay to short together any adjacent pair of pins. They are in the order (starting at the top on kindle 3) TxD, RxD, GND. The kindle 3 also has a 4th pin at the bottom, which when connected to the GND pin above it, enables +3.7v DC power to the top connector (in the top slot). You should verify the information above before using it. I'm assuming that, using the picture and "reading it" from left to the right WHITE: USB DATA+ -> 1st pin from the left GREEN (blu wire in my case): USB DATA- > 2nd pin from the left BLACK: GND -> 3rd pin from the left RED: +5V -> not necessary Is it correct? If so, what's the next step? |

The whole purpose of a USB serial adapter is to change the signalling protocol AND to shift the voltage levels. If is is indeed such a device, those wires are not as you described, but rather TTL serial Rx, TTL serial Tx, GND, and perhaps a power supply voltage. Read the specs for your device. It you have no docs, look up its make and model (or FCC part number if it has one) on the web... Or use the "poke and prod" method -- see which wire fluctuates (with an oscilloscope) when you send data to it from a host computer. Do NOT supply power from the host computer to a kindle over this cable. And if the signal voltages are wrong, check out my TTL serial level shifter circuit.

OR -
See top section reserved for "sticky" threads? The one titled "Serial Jailbreaking for Dummies"? Follow the directions about making up a LV serial to USB connection (with the exception of the connection points). |

Yes, the signal description are USB signals, because the only thing i did was to extend a "broken" usb cable that i had thinking it could do the trick....that's it... Unfortunately, i can't follow you guys when you say you need this, that, read here and there.... Even reading around, honestly, i can't find clear and "simple" explanations on what it needs to be done and how to achieve the goal.... SO...the one i'm using now it's basically a USB cable with wires plugged into the serial port....that's it... I understand that it's wrong... So....again....do i need something like arduino etc eventually or i can just use a usb cable and maybe adjust it with resistors????? In case i can use the usb cable, how do you pin it out to the connector?? Quote:

You posted this thread to the Kindle Developers Corner. At the top of the thread listing is a group of "sticky" threads (threads that will ALWAYS be stuck at the top). One of the sticky threads is the "Master Index" (i.e. where to start). It contains information on debricking a kindle using the serial port. That information INCLUDES links to threads that suggest where you can get a USB serial adapter, and how to use it. USB cables and USB serial adapters are VERY DIFFERENT THINGS. They have incompatible voltage levels, incompatible signals, and incompatible communications protocols. The purpose of a USB adapter is to convert BETWEEN TTL serial at the kindle at USB at the host PC. If you cannot grasp the basic information on what such an adapter is and how to wire it, you have no business actually using one (because it is far too easy to type something that will damage your device even worse and more difficult to repair). You need to take the time to actually read enough about this stuff BEFORE CONNECTING ANY WIRES, to learn ALL NECESSARY details. "Being sent around" is exactly what you need -- go study the stuff at those "sent around" locations, or find somebody with adequate technical skills and willingness to help you, to do all of this stuff for you. We cannot upload it into your head in any way OTHER than to give you links (i.e. to send you around)...
![]() EDIT: Here is a thread you can read, which talks about a specific USB serial adapter that I bought: https://www.mobileread.com/forums/sho...d.php?t=190149 I find it more than a little scary that you did not like "being sent around", and then you decided to connect raw USB wires to your kindle TTL serial port. What advice can we give you with such unexpected behavior? Last edited by geekmaster; 05-07-2016 at 07:53 PM. |

Look, i 100% agree that you can't upload it into my head....
I'm a software developer and i'm pretty handy with things too...so i have the "skills" for for both things (build it and use it).... I know that serial it's different from usb, but i thought that in this case it could just work (checking around)... But i guess that you know better than me that when you don't know something because you never dealt with it it takes 100 times more to get things straight and get your head around it completely. It takes 1/10 of the time though if someone can show you or explain to you what to do step by step.... That's why i asked for a step by step guide on what to do, where to find tools or how to build them eventually etc etc.... Sending me around is ok, but if you don't link exactly what i have to read / check, it might be 100% useless because if you're not into this, you won't pick things correctly and you might be looking at things that maybe changed during the time and so on or wrong POSTS/THREADS. What, don't you think that i've already been around the forum checking every single thread looking for info?? ![]() PS: i know what a "sticky " 3d is ![]() PS2: sorry for this anyway, but as said i'm feeling a bit frustrated about this cos i've my friend pushing me to have his kindle back from one side, and from this side i can't make progress xD Last edited by Tommyxx84; 05-07-2016 at 08:09 PM. |

Yeah, that is me and getting toolchains working for various kindle models (so I can eventually do kernel modules). What a PITA. But at least I cannot destroy anything with a misconfigured toolchain (I hope)...

Hi again.
Let me see if I can translate. The first thing you need to do is go read ALL of post one in Serial Jailbreaking for dummies. Then you need to read everything that geek and knc1 linked too. They are very good about linking to exact posts. If you are still having problems understanding this all. Then you need to head to your nearest hometown electronic place. Preferably take this forum with you. Talk to the guys or girls there. I am pretty sure one of them will know what to do. Oh and be sure and take your wallet with you. Techs aren't cheap. Oh and good luck. Or for $79.99 + tax depending on where you are, you can get a brand new kindle at Amazon. |
