Opps can not root or something like that - Kindle Fire General

I kepp trying to root my kindle but when I press 2 on kfu it has an error and my kindle freezes in the boot logo but I know how to solve the logo problem but I still can not root it

MY issue is similar, my KF will not go into Fastboot or stock Recovery, it reboots and sits at the first KF logo, it did try to go into recovery but failed and booted normal.
Get no error messages in the app or on the device, the only thing I get is sometimes Windows will say that the USB device has failed, I unhook the USB, reconnect it, and the app will reboot it normal

[Q] Bricked Kindle Fire - Won't Boot or Show up in Device Manager

Hi everyone. I'm new to the forum and I have a major Kindle Fire issue on my hands. I searched the forum for the last two days and found similar issues but nothing that exactly address what I'm dealing with:
I have a Kindle Fire running 6.2.1. I rooted it about a week ago using Burritoroot. I wanted to install TWRP and CM7 using the Kindle Fire Utility. I downloaded version 0.9.1 and ran the installdrivers.bat. Then I ran the "Install latest TWRP recovery" option. My Kindle rebooted and froze at the "Kindle Fire" logo screen. The utility got to "Waiting for devices, if it hangs here then reboot a couple of times." I rebooted but it always went right back to the logo screen and nothing happened. I disconnected it and shut it down because I had to go to work.
The next day I tried to boot the Kindle up and it wont even boot at all (after charging all night!) If I plug it into my PC then the sound chimes and the bubble pops up saying "Installing device driver software, Android ADB interface." followed by "Android ADB interface installed." In the device manager the Kindle does not show up at all. Not even as unknown device or anything. While the Kindle is plugged into the PC via the USB cable the "Kindle Fire" logo screen just flashes constantly. If I unplug it, the screen goes dark and pressing the button doesn't do anything.
I'm sorry if this post is long and perhaps I overlooked a potential solution to this problem but I'm freaking out that I somehow bricked my Fire. Please help!!

Is my Nexus 4 bricked or irreperably broken?

Hello people,
I have a German Nexus 4 and it gets stuck in bootloop whenever I turn the power on.
I've had issues with the phone since the last few months - i.e. random reboots, random program crashes.
But recently I tried to root it in order to install the Android L developer preview. It was during the booting process, when my Nexus crashed and it has been unable to boot ever since.
When I push all three buttons (power + 2 volume rocker buttons) simultaneously, I get the fastboot screen.
Choosing the following options has these effects:
Start --> phone tries to boot but gets stuck in bootloop forever and ever
Restart bootloader --> restarts the fastboot screen
Recovery mode --> phone shows the robot with an opened belly and a red warning sign (see photograph)*
Power Off --> turns the power off
Also, it is NOT detected or recognized by my Macbook when I connect the Nexus via USB cable. So it's impossible for me to access the phone via my Macbook.
*This is the screen shown when I try to go into Recovery mode in fastboot:
[can't upload outside link to image]
So this leaves me with no options as I never get further than the 4 turning circles forever and ever.
Is my Nexus 4 broken or is there still a chance to unbrick it? (I have a MacBook, so Windows programs won't work for me)
Of course it's not possible to recognize it when OS is not running.
Download WugFresh toolkit, ADB drivers (Universal) and the factory image. Enter fastboot, connect USB and flash the image
Your phone is not hardbricked, because it boots into the bootloader.
It might be recovered if you can access it with fastboot.
Try uninstalling all related drivers and install the Naked Universal Driver.
Thanks for your replies!
Unfortunately, the programs you mentionned don't work on my Mac (they seem to be Windows-only).
Also, how can I install stuff on my Nexus? Since it is not recognized by my MacBook, I can't load any files onto my Nexus.
And since any command on the fastboot screen only leads to the phone powered off, restart of the fastboot screen or the mentionned bootloop, I cannot perform any actions on the Nexus ...
Go to a friend with Windows.
Problem solved!
Somehow after the 1000th bootloop I finally reached the screen where I could wipe the phone.
And then it finally booted! Now all the data are lost and it's like a new phone, but at least it's working again!
How long was the boot loop? Was it the new boot animation from L?
Because when you flash L, the first boot up may take up to 15 minutes, leading you into thinking it's a boot loop.

Phone doesn't react to anything, doesn't boot

I might have bricked my LG G2.
Here is everything I did:
-I rooted the phone with the IO root kit
-wanted to installed a recovery so I installed TWRP manager
-applied SD card patch
-tried to install recovery with TWRP manager several times but app always crashed
-installed SDK on the PC
-started adb and executed "adb reboot bootloader"
the phone got a backlight screen and hasnt been reacting so far.
When I held the power button the screen went black but sometimes the backlight appeard again. I don't know how to reproduce the backlight though.
adb can't detect the phone when connected to the PC.
As soon as I plug it in dozens of Partitions show up. Windows show an error message for each of these partitions. It says I have to format the volumes to use them.
After testing I realized that everytime i long-press the power button for a few seconds the windows errors start popping up.
When i long pressed the power button for 30+ seconds to completely shut it down the notification LED started blinking red 8 times in roughly second intervals. then there was a short break and the 8 blinks repeated.
Thank you for all help, it would suck to have a 1 day old phone broke...
You probably chose the wrong device in TWRP Manager. Choosing the wrong device can easily lead to a brick because TWRP Manager may attempt to flash to the wrong partition. The G2 does not have a TWRP Manager flash available due to loki, so you couldn't have chosen the right device.
Almost have the same problem... the only difference is my black screen is blinking continuously while it is connected to the mac... Seems like it tries to boot but gets blocked and retries in a loop. Tried around now for two evenings without any progress...
Anybody who can help?

Device won't boot up.

Sooo as the title says, my phone wont boot up.
i have a Samsung Galaxy Core (prime version) and i tried to root it with kingroot (because i used Kingo Root and it was really buggy) and while i was rooting a message was saying that the phone might restart and sth like that.
So my phone did, and restarted at 47% of the root and from then my phone wont boot up. (the Samsung logo keeps loading, not frozen)
I tried simply restarting (power+down volume button), hard resetting via recovery mode, wiping cache, rebooted through recovery mode, pulling out the battery.
Nothing.
I have also tried to connect my phone to my computer, and it finds my phone but i can't check my phones files.
So what else can i do?
i am kinda new to android phones so yeah :/
