So, I was trying to root my Kindle Fire this morning, and successfully did it, but the Superuser app kept crashing (just giving background in case it is needed). I used the Kindle Fire Utility, and everything worked, except now my kindle will not boot into the GUI, it only reboots to the bootloader, then goes straight to recovery, even without pressing the power button. I tried connecting the tablet to the computer, but it will not show up on adb. Any help?
regardless if it is showing up in adb - use kfu option 1 - bootmode normal
if it says <waiting for device> power off by holding pwr ~20sec and pwr on again
the command should be resumed and finished - another off/on should bring you to system

So this morning I rooted my spare kindle fire with BurritoRoot3 and then flashed FireFireFire with it, then like a retard I used Kindle Fire utility to install TWRP. After that I tried to boot into recovery but it refuses to. All it does is sit at the yellow triangle and refuses to actually go into recovery... I can leave it alone and it will boot into the OS but I'm trying to install ICS or CM7. Any tips on how to wipe or repair TWRP/Firefirefire? Re installing TWRP doesn't work as KFU can't do anything due to it sitting at yellow triangle.
Do you hold down the power button until it turns orange? Make sure that you do... hope this helps.
If i do that it makes the power button turn red and then screen flashes and it goes to the same screen but the screen brightness seems to be turned down. After that it just powers off. I have a second kindle fire that works flawlessly and I got ICS running on it.. this one... not so much
would try to start the twrp installation - when it says <waiting for device> power off the kf by holding pwr ~20sec - power on again - the installation should resume and finish
if not check device manager for the correct drivers - maybe this helps:

I've checked the other two threads to know avail. My device reboots up to the yellow triangle, and then reboots infinitely. Here's my situation:
1. I think i booted into recovery using my roms reboot into recovery option.
2. My kindle fire is in a state of it can't turn on unless it is plugged into a computer/charger.
3. I don't see "kindle fire" in my devices on windows 7 and I don't see ADB composite device thing.
4. Using the install drivers.bat that is in the kindle fire utility says Driver name "Google, Inc (WinUSB) Status Ready to use.
5. I have tried the kindle fire utility to set boot mode to normal but adb and fastboot don't recognize it.
6. Also I've tried plugging into the computer with a factory usb cable and that also didn't work.
I'm wondering if i'm SOL.
[FIXED]
Okay, So I finally got my fire working! Charged it up through a charger for a little while. Booted into ubuntu 11.10 (32bit) with the firekit file and ran the install recovery script. It hung at waiting for device. I unplugged it and plugged it back in and tried turning it on and off and holding the power of the device for awhile and one time it just worked. Was able to reboot and boot into recovery and flash a rom.

You're fine.
First, charge the fire fully.
Second, read some of the threads in the development forum on getting it out of fastboot mode, because you are stuck in fastboot.
Third, do NOT reboot into recovery on the fire, it puts you into fastboot and....well you already see what that looks like.
Fourth, plug your fully charged fire into your computer and issue the commands to take it out of fastboot.
Sent from my Amazon Kindle Fire using xda premium
the command would be:
"fastboot oem idme bootmode 4000"
and
"fastboot reboot"
if it says <waiting for device> power it off by holding the pwr button for ~20sec till it turns of - pwr on again - the command should resume and finish
a second pwr off/on will bring you back to normal
I can't turn the power off though. Holding it down for any amount of time won't turn it off, and I can't get the driver to install. I can't get it to recognize it as an ADB device or a kindle.
nevertheless - to stop the bootloop you will need to charge it
do you use the original wall charger ?
if not take care the replacement charger has ~1.8A
if you plug it to the charger it would be fine if you can turn it off for better charging
if you can't turn it off - leave it - try again to power off after an hour
what happens:
if you plug it to a power source it tries to start - battery breaks down - tries to start - ...
If I plug it in to any source pc or charger it turns on gets to the triangle and then reboots, and does that for as long as it's plugged in. I've had it plugged in like this for a few hours and the only way to "turn it off" is to unplug it.
yes - this is a sign for a empty battery - atm the search function is'nt working but there are ~20 threads with the same problem - it was allways the battery besides 1 or 2 where the battery was so deep empty that they had to return it
charging with the computer will not work in this situation - the computer delivers only 500ma - that is too few
you can try to switch it to fastboot mode because then it starts the bootloader and don't go further (so it uses fewer power) - this is done by issuing: "fastboot oem idme bootmode 4002" - then let it do a bootloop - it should pickup the command
The drivers won't install for the kindle fire though, I don't think it's going to work that way. I'll try it again, but I've done this like 5 times to no avail.
if the right drivers are not allready on the machine you can't install them until you get it to stable state
the only solution (besides a factory cable) to change the bootmode in this situation would be firekit - this is a special crafted ubuntu on a usb stick because linux don't need drivers

Okay, So I finally got my tab working! Charged it up through a charger for a little while. Booted into ubuntu 11.10 (32bit) with the firekit file and ran the install recovery script.

good to hear that you got it working - good luck with your kf
I wrote this awhile back to provide known methods to enter each of these modes. I know it's rather wordy, but may help those that are newer to all this. See the link below for a more concise write-up. I'll try to keep this updated with any corrections and/or new methods and feedback is very welcome.
How To Enter APX, Fastboot Mode and Recovery menu
Special thanks goes out to tobdaryl for providing the foundation for this guide and to daws for
providing a previously unknown method (USB cable plug in while tablet is turned off).
Pertinent links:
The methods below written more concisely by tobdaryl: How to enter APX mode or Bootloader-recovery menu
Universal Naked Drivers (for APX/ADB/Fastboot modes): [ADB/FB/APX Driver] Universal Naked Driver 0.72
To install the SDK tools & drivers in Windows 7 (and other versions?): [HOWTO] Install Google SDK and ADB drivers...
The following instructions are written on how to enter APX mode. To enter Fastboot and Recovery modes, simply follow the same instructions but use the Volume Down button. Once the message: "Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK" is displayed, follow the displayed instructions to enter the desired mode. Note: The screen remains blank in APX mode.
When your tablet is turned off, to enter APX mode:
Make sure your USB cable is connected to your tablet and PC. While pressing the Volume Up button, press the Power button for a few seconds, and then release both buttons.
Make sure the USB cable is not plugged into your tablet (but is connected to your PC). While pressing the Volume Up button, plug the USB cable into your tablet. Release the Volume Up button after a few seconds (modified from daws' suggested method).
When your tablet is up and running, to enter APX mode:
Turn your tablet off and wait a few seconds. Connect your USB cable to your tablet and PC. While pressing the Volume Up button, press the Power button for a few seconds, and then release both buttons.
Make sure your USB cable is connected to your tablet and PC. Open a command prompt on your PC, navigate to the folder containing adb.exe, type: adb reboot and hit the Enter key while holding down the Volume Up button until the screen remains blank for a few seconds.
From a tablet based terminal emulator, type: su and hit the Enter key, then type: reboot and hit the Enter key while holding down the Volume Up button until the screen remains blank for a few seconds. One suggested app (by tobdaryl) is the free Android Terminal Emulator from Google Play. Note: You must be rooted for this to work.
Press the tablet reset with a paperclip while pressing the Volume Up button until the screen remains blank for a few seconds (the reset is located about either 25mm or 1" below the sdcard slot). Note: Do not press hard!
When your tablet is in Fastboot mode, to enter APX mode:
While pressing the Volume Up button, press the Power button for 10 seconds. Release both buttons a few seconds after the screen goes blank. One variation is to wait and press the Volume Up button immediately after the screen goes blank and then release it after a few seconds. If you wait too long to press the Volume Up button, your tablet will just boot up normally.
Make sure your tablet has the USB cable connected to your PC. Open a command prompt on your PC, navigate to the folder containing fastboot.exe, type: fastboot -i 0x0B05 reboot and hit the Enter key while holding down the Volume Up button until the screen remains blank for a few seconds. One variation is to wait and press the Volume Up button immediately after the screen goes blank and then release it after a few seconds. If you wait too long to press the Volume Up button, your tablet will just boot up normally. Note: Newer versions of fastboot.exe do not require the "-i 0x0B05" option.
Or, as a last resort!
Remove your tablet's cover, disconnect the battery, press and hold the volume up button, and reconnect the battery!
The following instructions are written on how to switch from one mode to another (not covered above).
When your tablet is up and running, to enter Fastboot or Recovery mode:
Make sure your USB cable is connected to your tablet and PC. Open a command prompt on your PC, navigate to the folder containing adb.exe, type: adb reboot-bootloader and hit the Enter key. Once the message: "Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK" is displayed, follow the displayed instructions to enter the desired mode. Note: I was unable to verify this method possibly due to having the AndroidRoot.mobi custom bootloader. This method only performs a regular reboot for me.

When your tablet is in Recovery mode (TWRP v2.3.x), to enter Fastboot mode:
Select the "Reboot" option and then select the "System" option while pressing the Volume Down button until the screen remains blank for a few seconds. Once the message: "Checking for RCK.. press key <Vol_Up> in 5 sec to enter RCK" is displayed, wait 5 seconds for the icons to appear, and follow the instructions to select/confirm fastboot mode.

Nice guide! Thanks for taking the time to gather the information and create this guide.
It is clear, detailed, and easy to follow.
It should be a stickied.
Hi I tried connecting my device to my computer after holding down the buttons to get into APX mode. And after about 5 seconds I heard a connection sound then Windows told me the USB device malfuntioned. Any idea why?? I'm trying to fixed my friend's soft bricked tablet which cannot get into fastboot mode.

A couple of quick thoughts if it's not the device itself: check to make sure the cable is good, try a different USB port, and try re-installing the drivers (using the Universal Naked drivers, specifically the APX one included in the package). I've had troubles on one pc where it would connect and disconnect - it was either the USB port acting flaky or the OEM cable I was using...
Watching Windows device manager, is it showing it as an APX device or something else before it disconnects? Also, what kind of error?
Hopefully some others may have added suggestions...good luck!

Ah I seemed to fix it when I held down the volume button while the tablet was off and plugged it in. Thanks for the help!

No problem at all and glad to hear it wasn't a complicated fix! With APX and other modes, do have the two methods. Holding both buttons at same time, but I do find somehow it doesn't always recognize them (maybe I'm not holding the volume button solidly?). As worked for you, the other option is to have it powered off, hold the volume button, and then plugging it in to get it to power on and go into APX mode (remembering it's just a black screen but can tell by checking Windows device manager - mostly mentioned for any others that may come across this!).
If have more questions on the rest of the restore process, might be good to start a fresh post for the remaining steps. Good luck with getting it back up and going!

I have Moto G4 Plus and its power button broke. Now the battery is dead and I am not able to switch it on even with a pointed object. I searched the net and found a way to enter recovery mode. I pressed the Volume down button and immediately plugged in the charger. Now I managed to enter the recovery mode but still, I need the power button to switch it on.
I found another way, but still, it did not work. I installed ADB Fastboot and opened the command window. I remember that I had even tried to root my phone so USB debugging was enabled. But this ADB command window does not detect the phone, even on typing "adb devices". How do Switch on the phone?

I tried with both (vol -) and (vol +) and it went into bootloader.
Try it, Then use command: fastboot reboot
( add "m" if you use mfastboot)
keep vol- pressed then plug an usb cable. leave the vol- in bootloader mode.
then just press power button to start
LG G6 H871 unrooted
I just can't get into fastboot or recovery mode. I've tried everything on the internet.
I've tried turning off the phone. Holding down the volume down button and then plugging in the USB cable.
I've tried adb command "adb reboot bootloader" which just reboots the phone until I can see the "enter your PIN" screen
The closest I got to the recovery mode was using "adb reboot recovery" which gave me the "no command" screen.
Any tips on this?
Have you enabled OEM Unlock option under Developer settings?
Yes. "Enable OEM unlock" and "USB debugging" enabled.
both oem unlock is on and usb debugging on and my computer has accepted the fingerprint from teh device to shake with adb. . still cant get into fastboot mode.what to do.
Is your phone rooted? If so use flashify to reflash recovery. You do know that if you want to boot in recover you have to let the power key go and repress it once your screen goes on right?
You can also try phone off. Holding volume up while you insert usb cable. Might be a tool that allows a command to be send to reboot it in fastboot mode? If not downgrade its firmware..

If I understand correctly, when you got to the No Command" screen, you were actually in Recovery. From my experience, the No Command screen is like a "greeting", if you will. Once you see that screen, you need to fiddle with the power & volume buttons. I believe the correct combination is to press and hold the power button. Then press and release the volume up button but continue to hold power button. If that is not the correct sequence you will need to Google for the correct order. Reference.
Considering that you are not rooted, there is not much you can do in the stock recovery.
EDIT 2 - Realized that this thread is over a year old and the OP has probably moved on. Didn't realize another member revived it. Sorry.
