It's a cable that forces the Kindle into fastboot mode everytime when you power it on with it attached, that's it's purpose & can't be used for charging.
Some of them look just like a normal cable, I got one the other day & it doesn't look like the quality of the official Amazon cable but most unsuspecting users would just think it's a 3rd-party charging/data cable.

I have almost the same problem, my Kindle loads "Kindle Fire" logo and does not go into fastboot by factory cable. It does not appear in the devices in w7x64 (adb drivers is installed).
I found a reason why didn't work fastboot - bad quality of cable. Try to make new.

You can check your wire,
Pin 1 should go to pin 4..
For a fast boot cable that's 5 volts to pin four
For an on the go cable I believe pin 4 goes to ground pin 5
I have to wonder if these poor cables we are hearing about are otg cables

[Q] One more charging problem with Nexus 7?

Hello! After some experiments with POGO contacts on my Nexus 7 3G I have the following situation:
1. The normal USB-charging can not properly start. The battery state in the Settings menu eventually changes from Charging to Discharging and back, the battery level goes down as it is indeed discharging. If the tab is off, then the charging animation is not shown completely in an infinite loop.
2. No any connection can be established with a computer using USB cable. Windows 7 machines just ignore this connection without any traces. Windows XP machines repeatedly show warnings about a non-recognized usb device although all drivers were preinstalled.
3. If I put a USB-OTG cable into the tab (even if the cable is empty from other side) android shows that the battery is charging. Neththertheless, the tab in this state correctly recognizes flash drives as it did previously.
4. The POGO charging contacts are alive. The charging is normal. Moreover, this charging alllows to normally connect the tab to computer via USB cable.
I used the last feature to return to the stock ROM and to lock the bootloader, so the device is ready to go to service. But are there some chance to fix the problem by my own?
Thank you!

It seems, yes, but it is very easy way to break:laugh:

No excuses for breaking it, I did not hook it up the wrong way for my GNex................

[Q] Amazon kindle stuck at logo even with fastboot usb cable

I have an Amazon Kindle Fire HD 7 inch tablet. I tried to install cm10 and it would only boot about every four tries so I decided to go back to the Amazon OS. After I flashed it back with the srt tool, it now only boots with kindle fire logo for about four seconds and blinks the logo again in a bootloop. I bought a usb fastboot cable. I bout the n2a cable that was recommended in the forum but it still boots the same thing while plugged in. Am I out of options? Thanks in advance.

I forgot to mention it's the kindle 2012 version.

Hold the power button for 30 seconds until it powers off. Now plug the Factbook cord into the tablet and now you USB port. The tablet should energize into Factbook mode automatically.

Thanks for the reply. That's what I've tried to no avail. I've even removed the back and unplugged the battery to make sure it was off. It turns on to the kindle fire logo even still. I have the motorola/kindle fire fast boot cable. I would purchase scoprn's cable but I don't want to waste my money if it's not the cable. The fast boot cable I bought was used by others users in this forum successfully. It's weird though, everyone seems to suggest that if it boots and is showing something then it's not bricked. I just don't what my options are at this point.

I recomend the adapter by blackhat i think hashcode has posted in his 2nd bootloader thread, goes in between a normal cable and the plug on the kindle.

Thanks for the suggestion. That's the one I purchased over the weekend. Hope it works.

Not recognising USB connection

Hi Folks,
Have a 7th Gen Fire7, which is currently not recognising that it is connected to a PC or charger via USB. Multiple cables, PCs, and chargers tried. Also power banks. It's definitely a problem at the device end of the wire.
At start-up, if connected to a computer the PC recognises the device in preloader mode briefly, but as soon as the bootloader or OS starts, nothing. No change if I enable ADB mode on the device (either in the OS or TWRP).
Left it connected to power overnight and charge level didn't drop, but didn't increase either.
Current state: TRWP + Stock 5.6.4.0 - factory reset.
What led me here?
- Was working normally in 5.6.4.0
- Decided to try the Fire7 tool to remove some Amazon apps and reduce load/improve performance.
- Attempted rollback to 5.4, not realising this would brick a 5.6.4.x device
- Subsequently, in a preloader loop
- Used the 'short trick' and Linux scripts to load the hacked preloader, then fastboot a bootloader, the ADB sideload an OS (5.4)
- Relieved, and out of time for fiddling, decided to put it back to stock 5.6 (as noticed the Kids side was a better experience, and my boy will be using it in a week for a flight)
- Grabbed the .bin file from Amazon and flashed using TWRP (expected to lose that bootloader, but didn't)
That's when I noticed that it was no longer charging or communicating with a PC.
Since, I've been through various upgrades and downgrades, resets, wipes, etc, all to no avail.
I don't think it's hardware - I can't have damaged anything through the short process as else the fastboot/ADB piece wouldn't have worked after.
I note that it can't be powered off whilst plugged in anymore. It will immediately start up again.
All and any advice you can offer would be greatly appreciated, as I'm not entirely certain where to go from here.
Many thanks.
Regards,
Gavin.

Can you help to solve/troubleshoot the problem from USB connection on your Fire tablet:
-> Make sure you check the microUSB port for damages.
-> Make sure the USB voltage/current is 5V/1000mA (5.1V/2100mA is recommended).
-> If the USB cable is broken. Ues an another USB cable or buy a new one.
-> Try to use an USB voltmeter/ammeter or didn't have. Use a multimeter.
-> Make sure the USB cable wiring is correct polarity. See attached image on this post.

>> Can you help to solve/troubleshoot the problem from USB connection on your Fire tablet:
Thanks for replying. Yes, can confirm everything is fine on the supply-to-Kindle side of things (and, indeed, with the port on the Kindle). Specific answers below.
-> Make sure you check the microUSB port for damages.
Port definitely fine, opened the device to check, all solder points to the board are solid, pins undamaged, no fluff/etc
-> Make sure the USB voltage/current is 5V/1000mA (5.1V/2100mA is recommended).
Yep, charger output is fine. Multiple chargers used, this device has previous worked on this charger/cable, and another fire continues to do so
-> If the USB cable is broken. Ues an another USB cable or buy a new one.
Tried multiple known-good cables.
-> Try to use an USB voltmeter/ammeter or didn't have. Use a multimeter.
Voltage output is fine and stable, as is the current.
-> Make sure the USB cable wiring is correct polarity. See attached image on this post.
Yes, wiring is correct.

Looks to be a similar problem (and chain) to the ones experienced here: https://forum.xda-developers.com/showpost.php?p=78943209&postcount=200
