Sorry for late response i was answering an pm First follow that download mode thing, I will later post the fastboot way if download mode doesn't work for your own safety cause fastboot is also dangerous :good: If you can't enter download mode at once, Try it several times.
Download the LG usb drivers if you haven't done that yet,
Since you probably aren't gonna use the android SDK but only to use fastboot/adb download this:

I have the same problem, no download mode on my G2 (European version, stock kitkat without root, bought it a week ago).
Just to be safe, the way I tried to launch it into download mode was:
1. Powering off the device.
2. Holding the volume up button.
3. Plugging in the USB cable (while still holding the volume up button)
The LG logo shows up for a while, after which the charging animation shows ups...

Your phone must be turned off
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
that is the known method for G2 unless you flashed a custom boot-loader or changed the keys to enter download mode or recovery etc .... now try to enter a hard reset mode but don't apply it or all your data will be gone i say again don't approve it it is power+Vol down
if it works i think the keys combination are still in default then try to enter download mode again
if it didn't work return the mobile to be fixed or changed
Thanks for your reply!
The method you described is the same as the one I used, unfortunately it doesn't seem to work. I can't seem to get it to boot into recovery either...
I believe this reddit post describes my problem:
https://www.reddit.com/r/lgg2/comments/2n4gqa/unrooted_lg_g2_on_stock_android_442_kitkat_will/
The OP's conclusion is:
So I rooted and installed AutoRec and that got me Download Mode. Afterwards I used LG Flash Tool to flash the stock KDZ file onto my device to unroot it and to see if Download Mode is still enabled which it was not.
I believe this is LG's way of preventing users from upgrading to unofficial/unreleased firmware.

I managed to fix the issue by performing an emergency recovery using LG software. It must have been caused by one of the OTA updates.
I have international D802 where I have installed a custom rom based on android 4.4.2. Yesterday I wanted to upgrade it to an android 5 rom and and mistakenly installed a new custom rom that was builded for F320S. After reboot only the fastboot mode was displayed. Then I’ve tried to repair the download mode by flash the img files, but as I’ve verified later they was not intended for LG G2 D802 32Gb version. So now if I try to enter either the download mode or the hard reset / recovery I see only the LG logo with security error.
I’ve tried a different button-combinations. Please correct me if it was wrong.
For power off I’ve pressed the power button for about 15 seconds, wait until the logo is displayed then hidden then shortly displayed again and then the display is black.
For hard reset / recovery I’ve pressed press volume down button and power button together until the LG logo appears on the screen. When the LG logo is displayed, un-pressed the power button, but keep pressing the volume down key and then pressed once more the power button. Then the LG logo is displayed again, and then below was the security error displayed.
For download mode, I’ve pressed and hold the volume up button and connected the USB cable. But after some seconds the security error was displayed and the device manager in windows didn’t showed any changes.
Is it possible to recover the phone from the security error state? Any help would be appreciated.
EDIT:
Solved in following steps.
1. Open the phone like described here: LG G2 is UNBRICKABLE NOW!
It was not hard and you don't need any special tools, only a small screw driver. Look first this both videos https://www.youtube.com/watch?v=15krGmydqgQ&feature=youtu.be and http://forum.xda-developers.com/show....php?t=2582142. The do the steps till you can access the processor chip. Ensure the battery is disconnected. By disconnecting the both left and right plates be sure to separate it from the surface.
2. Connect the phone to the PC with USB cable. Open the device manager.
3. Short the test pins on the chips, see the https://www.youtube.com/watch?v=FiofVOqfnxw with e.g. bent paper clip till you'll see the new QHSUSB qualcomm 9006 connection on COM port. Then you'll see a lot of windows messages about to format the new founded partitions. Close them.
4. Flash an images, like laf.img,aboot.img, boot.img from your phone model using export very partition see https://www.youtube.com/watch?v=_d5b_osUTug for details and files.
5. Now the download mode is available. Remove the usb cable, enter the download mode and flash a original stock rom for your model using the LG Flash Tool 2014.
Now your phone is unbricked!
Any questions?
What is the security error on LG G2? Is it a common way to reset some settings to reset it?
Added solution in the first post. If you have any questions, please post.
Ive done till step 3, only one window poped up, and i don't get step 4, i still got the security thing...
Help I guess?

You've shorted a wrong pin, please try again step 3 untill you will see the qualcomm 9006 and not 9008 or another number.
Hello all, I have been tremendously stupid and think i've buggered up my lg g2 d802. I was flashing stuff, made a mistake then went back to stock with the tot then kdz method to get to KK, then i tried to restore a twrp backup (gloudy g2 3.2) which has left me where i am now.
- previously download mode was working so i could just use the tot/kdz method
- but now neither download mode nor recovery mode work. it boots to lg screen whatever i do, then within 5 secs, reboots
- this is despite me pushing vol up + plugging in cable, or via vol down power then release and go in again on lg logo
- when i plug it into my pc, nothing changes on device manager, and there is no sound notification that a device has been plugged in
Is this it for me and my fairly new G2??
Hoping someone can shed some light. Rushing to root phone again to send back warranty replacement, in my haste my laptop died mid flash and now can only boot in Fastboot and Crashdump Mode.
I am attempting to restore to factory via the MSM tool but cannot for the life of me enter EDL mode.
With phone powered off and pressing the vol up and down keys while plugging into the PC, it only enters Fastboot mode
I have tried to do it with phone off, rebooting from Crashdump mode, from fastboot and it seems that no combination allows me to do so.
I have also tried just vol up and vol down. App loaded at the flash screen, not loaded, etc.
Thanks in advance

What I did when I was in Crash Dump Mode was,
Press and Hold Power Off and Volume Up button and release when the screen goes off. Now your phone is switched off. Now to enter the EDL mode you need to press and hold volume up and volume down buttons at the same time...and then connect the mobile to pc while still holding the buttons. Done. MSM tool will detect your phone.
NOTE : Also keep the Device Manager window open on the PC while u connect the phone to pc and check if it shows up there.

It always seems to take me several tries to get it right. I think if I don't hit the vol +/- keys right at the exact time that's the problem. Just be patient and keep trying. The first time I did it, it took me what seemed forever. Thought maybe my phone was broken.

Hello Folks. So i have found myself in this situation as well. MY phone wont go off and keeps restarting to CrashDump Mode. As such can't seem to get into EDL mode inorder to flash. Any tips? I have tried all the above methods nothing seems to work. Is there a different key combination or a fastboot command i can use to achieve EDL? Help a brother i'm going nuts. Device IN2020

You just need to keep trying it. Make sure you hit vol+/- at the same time and hold for a few seconds, plug in the USB cable, then let off the vol keys. It's difficult to do and get right with two hands. Recently did it again as I wanted to upgrade to the 11 beta from a clean system. Seems like it took me forever to get it this time but eventually I did.
Use usb 2.0 port.
After using 2.0 instead of 3.0 and the phone connected stable for a while (after many tries)
able to finish the msm operation successful ..
But phone not booting .. getting black screen after 1+ logo
at this point I thought to clear cache but My phone is locked I cannot use any recovery .. I cannot even go into oneplu recovery LOL .. It seems like I am doomed
For me personally I could only get it to work on USB2.0 ports. On USB3.0 it just puts me back into fastboot mode or when it does go into EDL MSM tool just fails with a communication error immediately.
I kinda bricked mine as well messing around with GSI ROM's and flashing too hastily and to the wrong partition lol.
It has always worked for me with USB 2.0 port and non oneplus cable.
originable cable would not work for me on usb 3 or USB 2 port, but 3rd party cable start immediately with USB 2 port.
I've had the issue where EDL mode works..... for a few seconds, then the phone reboots.
Very frustrating!
The MSM Download Tool does spot the phone, but since the phone seems to reboot, I don't have enough time to do anything!
Any ideas why this is happening?

You need to already hit start on msmtool BEFORE plugging in phone
1- start MSM tool (prepare the settings and choose the right oos)
2-keep the cable connected to one end (I prefere to keep it connected from the phone side first)
3-keep holding volume up/down for 3-4 sec and connect the other end of the cable to your PC
4-your device will be connected directly stop holding volume up/down and in msm tool press start wait for ≈300 sec
5-now your device should work as it was before

This is a royal pita! I remember when it used to be fun....
Anyway, I've been trying every trick in the book, and then some, but shiznit just isn't going right! The holding of the up and down buttons would be easier if this was the pixel, but it is a tad hard to not mistakenly hit the power button on the other side.
The device manager shows the Qualcomm QDLoader and the msm Downloader is showing the infamous waiting for device... I've been at it for 8 straight hours and if there was a local OnePlus store that sold the international version of the OP8P, that's where I would be heading in a few hours.... It's really frustrating to say the least.
Anyway, when I'm in the bootloader, the device manager shows the Android phone, so I'm thinking that maybe I am in the edl mode when the Qualcomm port shows up, but like I said, the msm is waiting....
tried everything and it is constantly booting into bootloader. I even tried an adjusted fastboot script to boot into EDL but it still boots into bootloader. I have booted into EDL before on a OnePlus 7T, and I have tried multiple times by pressing the OnePlus 8 pro volume buttons at the same time, but always bootloader. Just to check, I tried doing it on my OP 7T again and it worked perfectly fine. Help????
I have had to flash stock 4 times because I land in crash dump mode and it has always been a tricky situation to get into edl.
What worked for me 100% of the time was following the steps in the youtube guide below.
From 2:30 onwards
Hope it helps
I had the same issues, but fixed once read comments as per above. Let me summarize what I did:
1. installed driver Qualcomm HS-USB QDLoader 9008 (I'm using Windows 10) - driver in a cab file should be unpacked using command expand (with proper switches) to preserve folders.
2. launched MSM DT and had it configured and then pressed Verify\Start, as EDL is available only for very short time - 2-3 secs with screen turned off.
3. as my phone was stuck in booting loop I was just keeping presses Vol+/- waiting for EDL to be entered, MDM will find the phone and start uploading data.
Just don't give up trying.

Try different ports. My usb 3 port would force it into fastboot but usb 2 was fine.
What to do if the device doesn't have any usb 2.0 port?
