Hold the volume up AND down button down along with the power button till the vibrant screen flashes once. the let go of the power button but keep holding the volume up AND down button untill it goes to the download screen

I just spent the afternoon recovering my phone after the OTA update.
I was able to get into download mode using the following:
With the phone powered off hold BOTH volume keys while simultaneously plugging the USB cable(that is already attached to your pc) into the phone.
Worked every time for me. Hope this helps.

Hi I have tried that and other buttons combination for the past 30 mins and found nothing. I have read into that any vibrant from the batch in august have been disabled for the download mode, is this true?

Pull the battery out first.
plug in usb
hold up, down and power buttons
reinsert battery with free hand.

That's how it works for me.
If I hold the power button while doing the above I only go into recovery mode.

i'm starting to get worry because i tried everything and nothing is happening. it is as if my phone has disable the recovery mode.

The volume up/down button thing never worked for me either. For me, the only thing that works is adb (the android debug bridge). Download/install the samsung drivers, and the android SDK (see messages on this board for links & instructions).
On the phone go to Settings -> Applications -> Development and check the USB Debugging box. Connect your phone to your computer via the USB cable, open a command prompt & type 'adb devices' w/out the quotes. You should get one listed device if you've done the above correctly. Then type 'adb reboot download' to put your phone into download mode.

[GUIDE] Entering ADB/Fastboot/APX mode instructions

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!

Hi @wha2do,
This morning I followed a guide written years ago instructing "-i 0x0B05" as part of a fastboot flash, which was a problem considering I used the latest fastboot available ...
Thanks to your guide, I removed that portion and it worked like a charm. Thank you man

Hardware button don't work in bootloader?

Hey guys. I just got LG G6 H870 model. Unlocked bootloader without much problems, but issues came later. While being in bootloader I can't do anything, hardware buttons seem to not work. The only way to get out of bootloader is to use "fastboot reboot" command, but that prevents me from getting into custom recovery after flashing it. Only entering download mode works (holding volume up and plugin in usb cable). Non other key combination work until I boot into system.
Can this issue be somehow resolved?

I had similar problem myself with entering recovery more and the reason behind it was that I didn't press the button combo in proper way. what you actually have to do is while you in fastboot mode you press down and hold power button and volume down button. phone reboots after a moment and you should still be holding these keys and when lg logo appears you let go of power button for brief second and then press it back again and then when a prompt on white screen appears just go yes two times and phone shall boot in recovery mode . I had watch a tutorial movie to figure that out. other easy way is just to have adb enabled and reboot it with adb reboot recovery command via USB cable

No, because I had G5 and I know the proper way to do that. Problem is I can hold the power button as long as I live and the phone won't reboot, regardless of pressed combination or power button solo.

and the adb command way ?

Well... Nevermind, turns out vol down button isn't working at all.

still good way around is adb reboot recovery

Im lost

was trying to root my lg stylo 2 Walmart family mobile(t-mobile) and i unlocked the bootloader and installed twrp but it just says no command when i boot into recovery.

Then you didn't flash the recovery properly, it's fairly simple. If you're able to get fastboot (shut off the phone totally, hold Volume Down and plug in the USB cable attached to a computer, it should go into fastboot mode almost instantly, if not then there's an issue someplace).
After that using fastboot with the recovery img file for TWRP:
Code:
fastboot flash recovery (recovery_file).img
Wait, if it says flashing successful then before you do anything else, type the following:
Code:
fastboot reboot (but do NOT press Enter yet)
Get the phone in your hand, still connected to the USB cable, and get your fingers on the Volume Down + Power button but don't put them just yet. Carefully tap the Enter key with a pinky or something to trigger the device reboot, press and hold Volume Down + Power till you see the LG logo, let Power go for a split second (still holding Volume Down) then press Power again and hold it till TWRP loads.
If that doesn't work - and I've done that hundreds of times - there's something going on with your device, perhaps the bootloader isn't truly unlocked - that checkbox in Developer Options doesn't mean it's unlocked, it just means it can be.

Cannot access fastboot or recovery

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.
