[Q] Kindle Fire not recognizing USB

Hi all,
Some time ago i rooted my girlfriend's KF. It's running the FFF 1.4a and TWRP.
A couple of weeks ago she complained that the kindle wasn't being charged anymore. The result was that the Kindle was dead and after pressing the power button it appeared "Charling low battery - Please wait".
I tried every single procedure that i found here: pressing the power button for 30 secs, the Kindle Fire Unbrick Utility with the shorting trick, the SoupKit...
I managed to boot in TWRP and charge the KF there. Now i have 100% battery.
I boot system normally but the Kindle continues to don't charge normally and it doesn't even recognize that the USB cable is on.
The cable is OK (works in my Xperia Play). I already tried another cables. I already tried to charge via the stock wall charger.
Is it possible to be a software issue? I'm starting to think that the conector is broken/damaged.
I will flash another ROM to see if it's this the problem (I'm currently running CM9)

Flashing anything other than CM9 would be a good idea

Ok. I'll try that and will post the result

No good... At first boot after installation of new ROM, windows recognized the device, tried to install drivers but very quickly it stopped to recognize...
Now it's charging, but only with the cable inserted in a very particular position.
I'm completely clueless about what to do....

what about connected to the wall? same connection problem? then you have a bad connector. use soupkit and flash stock, and return to Amazon for a replacement. or open the case up and solder the power connector back on,

With the wall charger I don't get any charging. Do they send another Kindle overseas (I live in Brazil)? I think it's a connector problem...

I don't know. You would have to talk to an Amazon representative.

bricked after installing COTR

After installing COTR with the KFU, i went and downloaded FFF and the 4.2.2 ROM. After i plugged in the factory cable and plugged it into my computer to get it into recovery mode, After using KFU to send it to recover it froze on the kindle fire splash screen. I turned it off and turned it on again and it went in a endless loop of turning on and off on the kindle fire splash screen the orange one. Confused where i should go from here.
Running Win7 64-bit

What happens when you plug in the factory cable?

it keeps cycling on and off

What's the interval between on and off?

Just pluged it in and now it is stuck at the stock static kindle fire screen. Device now appears as unknown.

When it first comes on, does the kindle fire logo stay brightly lit, or does it go dim at any point?

Starts bright and then goes dim right after. Driver error says code 43.

You need a factory cable.

i have one, that is what i'm using.

Let me rephrase that. You need one that works.

oh dang, well the good thing is SkOrPn is already sending me another cable because he didn't like the one he sent me. Hopefully it works then. Out of curiosity, how do you know the cause is a bad wire? So i know what to look for.

If the factory cable were working properly, the Kindle Fire logo would stay brightly lit, indefinitely. There would be no change in brightness.
[Edit:] The fact that your KF logo goes dim means that it's not staying in fastboot.

I sent him a second cable this morning. The first one was an emergency cable (test cable of different design) that I kept around just in case (I was out of stock when he ordered), however when I assembled it i noticed the case was way too small for the mod and I had to apply tremendous force just to get it to partially close. With that said, I tested that cable over and over multiple times with a very expensive multimeter. But maybe it has a intermittent connection I could not find with a meter, thanks no doubt to the force I used to assemble it. Possibly broke a solder joint is my guess.
Anyway does this cable need to stay connected or just launch Fastboot? When Fastboot launches don't you guys remove the cable and then attach your normal cables? I was told not to keep the cable connected once Fastboot launches and to attach a normal cable for fastboot commands. Is this no longer true or has that never been true?

That's correct. Once the device is in fastboot, there's no need to use the cable anymore.

Ok, ramsv94 told me that the cable is not "keeping" the device in fastboot. However once the device enters Fastboot couldn't he instantly remove the cable? And if so, if the device does not stay in fastboot mode once the cable is removed, how exactly is that the cables fault? No one has ever mentioned to me that the factory cable is responsible for "keeping" the device locked into fastboot mode. So now I am confused. Since that cable tested good over and over it makes it even more difficult to understand how it could be bad now. Lol...
I think I am going to completely rebuild my Bench Tester with a new female port this weekend. Just in case. Thanks soupmagnet for the quick response.

Here's the thing,
When the device is connected to the USB with the 1 & 4 pins connected, the device will boot into fastboot and stay in fastboot...period. With the stock bootloader, the device cannot start in fastboot, then start to boot normally. If FireFireFire were installed, however, the device would always start in fastboot mode for a few seconds, then proceed to boot normally. This function was added to help people in certain cases where the device is set to a normal bootmode, but without a working shell needed to enable fastboot.
There are two ways to determine whether or not the device is in fastboot. One, is by looking at the Kindle Fire logo at startup. If it is in fastboot, the Kindle Fire logo will be brightly lit and stay brightly lit. The other way is to check the system for what type of device is being connected to the USB. In Linux, this is done with the 'lsusb -v' command by checking the value of "bcdDevice". In Windows, this is done by looking at the device manager.
As astronomically improbable as it would be, ramsv94 has no way of determining, just by looking at the boot logo, that the device ever started up in fastboot and then began to boot normally with the stock bootloader installed.
Nevertheless, it's great that you're concerned about your customers, and your product, but you really have nothing to be worried about. You do good work, your cables are top quality, and this is the first one that I have ever seen that didn't work properly. Hundreds of Kindle Fire owners (including me) owe you a debt of gratitude for your service, and I can only hope that you continue to do so. :good::good:

thanks for the props bud... I am not worried any, I just get angry at myself when a tested good cable does not do its job just 3 days after I shipped it. you start to try and find another reason why this could be the case. A few hours ago I ordered two new Sparkfun micro-b breakout boards and I am going to redo my bench tester because this thing has been used thousands of times since late 2011. I test each connector before I solder on the wires, after I solder on the wires and after I hot glue the case together. That's three times during one cable build, so multiply that by 1100 cables and well you get the picture.
Anyway, I cant wait to see what happens when he gets the normal cable I built for him. lol

Can i use KFU to install FFF onto my Kindle or not?

Do you have access to fastboot?

This is where i am at right now. Kindle screen is lit bright so it is in fast boot mode. It is showing up on my computer as Android ADB Device. KFU says its offline. Attached Picture.

question about hard brick

hi i got this kindle off my friend i think its hard bricked not sure what he done, what happend is power light comes on and kindle fire logo then powers off, windows see's nothing. kindle fire logo seems to be yellow. so assuming its not rooted. just would like to know what type of brick this is and how to ge out of it if possible

Doesn't sound hard bricked, I would hook it up to a fastboot cable to see if it will enter fastboot mode, though the bootloader seems to be acting odd(unless it's a low battery but I think it would flash a low battery symbol on the screen instead of kindle fire).

yeah it has power as it will do the same when unplugged. So to make a fast boot cable solder 1 to four is that right?

Yes that's pretty much all there is to it, though the cable has to kinda have the contact point for what I think is pin 4, because its not usually used so not all cables have a contact point for it on the little PCB.

Yeah just popped one open and has four so red to white? Also could you direct me to the thread to what to do once I have created one

ok done cable plugged in still doing same thing???

That's not what pin 4 is, pin 4 has no wire coming from it, there's a guide that tells about this around here somewhere, look in this thread for a link at Q20. http://forum.xda-developers.com/showthread.php?t=2228539

kindle screwed up - no bootloader :( ;(

hi y'all nice and lucky people! Kindle Fire Murderer (me) has literally murdered his Kindle! you see, it has FFF with android Ice Cream Sandwich, but I wanted to dualboot with stock rooted, and was too lazy to go to recovery and mtp, so using fastboot I just flashed the FFF extended zip as a bootloader, and now I cant turn on my Kindle FIre! I tried the 20 seconds hole power button, and still, it doesn't turn on! even Fastboot doesn't work! and the back cover wont open, so no, I cannot do the USB Boot stuff! :crying: :crying: :crying:

so like, I connect it to the metal frame using the paper clip? if yes, then once that is done, in the firekit usb repair stuff, I chose usb boot twrp, so when it is doing that, should I keep the aperclip connected to metal frame and pin? or only for the first one second I connect the paperclip? thanks, in advance.
Sincerely,

No power on Fire TV

First post here looks like a great site . I have done some reading but could not find what i was looking for so I'm asking for a little assistance.
Came home today and my Fire TV was dead it would not power on i have tried leaving it unplugged for 20 mins, moved to new outlet in house and nothing is working. Is there any way i can communicate with my Fire TV or is she just a paper weight now?
Thanks
