You need to shut down the device. Afterwards, press and hold the VOL UP button while connecting the USB to the device. Keep the VOL UP pressed and it should enter Download Mode.

Reflash 4.4.2 - takes a couple of attempts sometimes. - Also don't flash any custom kernels cause they are not set up to run with KK's new BL yet

Did you manage to root? Do you mean you re-attempted to root 10-15 times?

For me on Verizon Note 3 this worked, but the button combo is different. It's the same as ODIN/Download mode:
Hold Vol down, Power, and Home... then Cancel ODIN/Download mode using Vol Down.
I had this same problem where I'd got myself in a "recovery" bootloop from Baja KK ROM... I had a custom power menu that allowed you to choose recovery as a boot option as opposed to selecting it at startup (I know, so hard). I would have the Galaxy Note 3 "Custom" screen then say Recovery mode in the upper left corner in blue, then reboot, etc... Anyway this seems to set it back to normal boot mode.

Bricked vs980 can't access recovery or download mode

I have the latest TWRP installed. Flashed CloudyFlex 1.3 and noticed that if my phone was in a 3g area, it showed I was roaming. I found this thread: http://forum.xda-developers.com/showthread.php?t=2647122 and flashed the vs980 flash zip. Can't get the phone to boot. It shows the LG screen and then it fades away to black and nothing. Tried getting into download mode but it won't do anything. Tried booting into recovery and it won't go. Any help is appreciated, but it seems hopeless at this point..
Update: Interestingly enough, there's hope. For some reason, the usual way for entering download mode didn't work (hold volume up and plug in USB) I was able to enter download mode by plugging phone in first, then holding volume up and power. At this point the download process is stuck at 0%. If I get this thing unbricked I'll keep posting updates as to how

Downloading the tot file now. It'll take about an hour to download. Thanks!
Phew...it worked!
It's odd that I couldn't get into download mode holding volume + then plug in USB. It works everytime if I plug in phone first, then hold volume+ and power. I see LG screen first like normal bootup, but if I continue to hold volume+ and power, it switches over to download mode.

I'm having the same issue. I can't get my phone into download mode or recovery mode. I tried to plugging in the phone first and hold down vol + and power. But still nothing happens, the red notification light blinks when I continue to hold the buttons down. Can you help me out with this?

Rooted via Kingo - Phone boot loops into recovery mode. Unresponsive.

Recently attempted to root via Kingo after backing up date with Kies.
Upon completion of what appeared to be a successful process, phone began rebooting continuously into recovery mode, powering down and then repeating. Attempts to boot into recovery mode (Vol up, home, power) fail as phone is unresponsive. I'd really like to hope there's a way around this.
Repeat: Phone is unresponsive to key press and does not boot long enough to recognize via USB on PC.

Pull battery, put back in and boot to download mode. re-flash stock rom then flash cf-autoroot (make sure it's the right one for your version of Android).
Don't use Kingo app again...

[Q] Dead LG G2 Sprint

I have lg g2 sprint version. I have unlocked it by following a tutorial on youtube. On the ui there was a message that there is software update and i tapped to install it, but it was stuck on fastboot mode started udc_start() so i followed tutorial from a forum and fastfbooted boot aboot recovery and laf, but forgot to run fastboot reboot and turned off and on the phone. Now when I try to start the phone it shows the lg logo and after that only the led is flashing no matter if it's charging or not. Any ideas what to do? I have plugged it in to power it, but I am not sure whether it's charging now.
I can enter in download mode by pressing volume up and power button, but I don't have pc near me to try to flash to stock.

The situation after a couple restarts is:
When I put to charge the lg logo appears and the led is flashing from yellow to blue
if I hold down and power button it says "Recovery mode. Loading..." and nothing happens
If I hold up and power button it enters download mode
Can I charge the phone in order to flash it to stock?
p.s. I am turning it off by holding the power button for ~20 sec

Cannot enter recovery mode after updating CM13 nightly

Hey guys,
I feel totally stupid for writing this post but I'm actually out of ideas how to get out of my situation. Also I didn't find any comparable topic here on xda. So let's hope you can help me and a big thanks in advance!
First of all i have a flashed D802 running TWRP and CM13, which worked well the last weeks. I thought about updating to the todays nightly as it is already a few weaks since I did my last update. I downloaded the nightly via the CM downloader and started the installation with running phone. It rebooted into recovery mode and installed the nightly without any problems. After the installation was completed the phone automatically rebooted and this is where the problem starts.
I am stuck in "bootloop?" at the CM logo. It is not automatically restarting after a while but just loading and loading and nothing further happens. I am not able to enter the recovery mode via the factory reset (Pressing Vol Down + Power, releasing after the lg logo appears, pressing and holding the power button again).
This never happened to me and as I am not able to enter TWRP I am not able to install a previous release or a backup. What am I doing wrong this time and what can I do?
Thanks for your support!

Actually I don't really know how to do this when I'm not able to enter the recovery mode? Is there a certain way to do this?
In the meantime I managed to enter the recovery mode / TWRP via a mode I don't know how it is called. I pressed vol down + pw btn, released after the LG logo appeared and pressed vol up + vol down. I guess my userdata is deleted by now, which shouldn't be a big deal but I am getting redirected to the recovery mode. I tried to install the yet working CM13 nightly but it has the same problems now.
Now I have two questions:
Does anyone know which part of the system is broken now / which part I need to update in order to get my phone back to life?
Is the download mode working if my phone is rooted? I am able to enter this mode.

yes you can enter the download mode: turn down your phone, press and hold volume up button and connect the usb cable, release volume up when your screan shows dowload mode.
then follow this tutorial to restore your phone back to stock http://forum.xda-developers.com/showthread.php?t=2432476
