Rooted my kindle fire first gen and installed cyanogenmod 10.2. Everything works fine, except for the fact that i cant reboot. Everytime i attempt to reboot i end up in boot loop. The only way i can get it turned on is if i plug it in to my laptop and use this method, Unplug the Kindle Fire from the USB charger cable, press and hold the power button (it should not turn on because the battery has run dry), while still holding the power button, plug the USB charger cable in (it should not turn on yet), wait for at least 40 seconds while still holding the power button, and once the kindle powers on, immediately let go of the power button and pray. Anyways, I was wondering if anyone had a fix for this problem. Thanks.

Describe the "loop" your device is in while unplugged. Also, what was the main problem, other than not being able to enable fastboot, that prompted you to buy a factory cable?
I have come into my possession a Kindle Fire 1st generation. When I got it, the youngster said it was “hacked for the Amazon App Store”… and the battery was dead. I traded an older laptop for it. I put it on a charger for a day or so and left it. It would boot to the “Stock” logo for several seconds, then the backlight would go slightly brighter and it would shut off.
I started reading up about some of the power-on issues around the web. I found most of my answers on “xda-developers.com” for my TF101 so I gravitated here.
Here is what I’ve done so far:
1. Acquired a factory cable... SO useful.
2. Flashed FFF v1.4a and TWRP v2.4.4.0
3. Played around with fastboot.exe commands -update, flash, erase, getvar, reboot, help
4. Flashed a stock bootloader and recovery… trying to get it to charge.
5. Disassembled and tested battery voltage… 4.10VDC on a 3.7V battery. That sounds good to me.
6. Tried the firekit boot from Live-USB. Won’t stay powered on.
Right now, I’ve flashed the FFF 1.4a and TWRP v2.5. What happens is, in normal boot, the fire boots to the FFF logo (White &Blue) goes to “Booting” and the power switch LED gets slightly brighter, then the backlight goes slightly brighter and the whole thing shuts off. If I push power to go to recovery, the fire shows “Booting.” Then, the power switch goes orange, then it goes off, then the whole thing shuts down. I cannot do any ADB commands because the Fire will not stay powered on in that mode. The factory cable keeps it powered on, but I’m stuck with fastboot.exe commands in that mode.
I do not have a stock charger. I’ve been using my charger from my TF101 and a cable from my phone or the factory cable. I’ve been futzing around with this thing for a few weeks and would like some input. I haven’t found an identical issue so I’ve decided to create a thread.
I’m wondering if I have a bad gate on the memory chip… I’ve seen desktops and laptops shut down with bad memory in the past. I’m reasonably savvy with a command prompt and not afraid to crack a box.
Hold the power button until the device shuts off completely. Plug it in to your USB cable power source (not the factory cable), and let it power on automatically. Immediately after it starts to power on, hold the power button to shut it off again. Let it charge in this state for a few hours and try to boot into recovery again.

Thank you Soupmagnet. I've done this and let it sit for a weekend... sorry I didn't mention it before. With a voltage reading of 4.1, I think I have a full charge (by the way, it doesn't drop over a day or so). You can be assured that I've tried most everything before posting. Please be gentle if I didn't state it previously
One of my issues is I can't get to anything on the fire itself. Even with the factory cable, is shuts off if I choose to continue... hold the power button and choose recovery, normal, reset boot mode. Is it supposed to be able to go to recovery when the factory cable is connected? It only stays powered if I leave it at the FFF logo.

What command did you use to install TWRP?

Fastboot -i 0x1949 flash recovery c:\KFU\recovery\twrp.img.
This is after I renamed the v2.4.4.0 file to old_twrp.img and downloaded the v2.5 that I found last Friday. Previously, i'd used the KFU. Last week I played around with flashing different bootloader and recovery to see if I could get it past the FFF or stock. At this point it's a challenge to get it to go further than FFF.

Use fastboot to flash this to your system partition and see if you can boot normally.... http://d-h.st/NzN
Perhaps it is hardware, not software
Just had a very similar issue. Turned out to be stupid simple.
Use spudgers to gently take the back off the case (a small flathead screwdriver should do the trick). then check the connection between the battery and the motherboard. In my case, my daughter had dropped it enough times that the connection was not all the way out but not enough in. This caused the exact behavior you are describing. Took me 2 minutes to fuss with once I got motivated.

Hi, I recently make a full wipe my device, and my phone was stuck on logo, any way I thought I will flash another ROM some other time, i rebooted to recovery and turned phone off, than I plug it in to charger, charge it, and leave it. Now today I want to flash ROM, and I can't even turn on my phone, when I plug in charger also nothing is happening...
Plug it in the laptop and keep trying button combinations, like power + volume down multiple times.
I can not get my wife's fire HD 8.9 to boot. When I turn it on the Kindle Fire screen appears for about 5 seconds, then the Kindle Fire goes out, but the screen is still backlit.
This device is completely stock with no modifications. It did this when I turned it on one day, no previous problems.
I tried holding the power button down for up to 2 min. After I hold the button for 10 seconds the backlight goes out and the kindle is completely off. I tried letting the battery go completely dead, then charging it for several hours with no change. I tried running fastboot, but it is stuck at <waiting for device>. My computer does not see it at all. I do hear the chime that something was plugged into the computer immediately followed by the chime that it was disconnected, but nothing shows up in my computer at all.
Is there any hope for this Kindle, or is it bricked for good?
So I assume you're on windows. That beeb you hear is the fastboot mode you need to load drivers really quickly during that beeb. At that point fastboot shoukd work and you can issue a command to get into the factory restore.
I got it working again.
The problem was simple, I did not have any drivers installed on my computer for the kindle (I have never plugged it into this computer before it would not boot). I found the drivers to download here: http://forum.xda-developers.com/showthread.php?t=1890413
I was then able to get it into fastboot and recover it with instructions from this thread: http://forum.xda-developers.com/showthread.php?t=2011126
HI there,
I have a Kindle Fire 7 and it's stuck in a constant reboot loop. Nothing shows on the Kindle screen - the only way I know it's rebooting is because I have the device plugged into my PC and it's making the USB device on/device off sounds.
I was attempting to downgrade the Fire using amazon7gentool_v1.8. I asked to downgrade to FireOs 5.4.0. The flashing was successful at which point I did the data wipe and cleared the cache. When I restarted is when the on/off loop began.
The file I flashed was from the Amazon servers and is called "update-kindle-55.5.7.9_user_579225620.bin"
I've tried holding the power button down, holding the power button in combination with the volume-up, and holding the volume-up button - all while plugging the device into a charger.
I've also checked the Windows Device Manager to see if I could find any info. When the Kindle is powered on, it shows up in Device Manager as "mt65xx preloader."
I've searched everywhere but can't find any instructions that are applicable to my situation.
Any tips would be much appreciated! I'd love to get this unbricked, and ultimately get a regular Android tablet build installed.
Thanks,
Robert.
