So i discovered a strange thing from my G3 while trying to upgrade to 10E. My phone is unable to enter download mode to flash the update. I have done the procedure a in the flashing thread:
-turn off phone
-unplug USB
-hold down volume up
-plug USB
i can head windows play the device connected sound then proceed with the phone just displaying the normal charging display.
also, adb reboot download does not work, adb reboot recovery does.

I had same issue, just make sure that you plug in the USB cable fast after you hold the volume up and also make sure you continue to hold the volume up.

I tried a thousand times but every time it just start up mobile phone instead of going to Download Mode.
Remove the battery for a few seconds and be sure to plug into usb 2 and not into usb 3 port on your pc
I tried that too. Removed battery for seconds and connected to USB 2.0 but same issue. I wonder it connects to PC and LG Pc Suite without any problems. I'm sure all rivers are already installed but wonder why it can't enter download mode.
I lost LG original USB cable and use other cables ( I tried many ).
What's wrong then?!!! I even tried Windows XP and 8.1 but both same issue!
I'm having the same issue only I think it's because I really bricked my phone, not able to boot up or anything.
My gives me an error saying fast boot and a couple of commands with a black screen, Unable to get to download mode
Dear xda-developers-community,
I'm trying to get a phone of a friend of mine working which just reboots whenever the phone is started. The resulting boot loop can only be interrupted by taking the battery out or wait until it is depleeted.
In order to fix this soft-brick I first tried to use recovery by pressing VOL - & POWER. In the menu, I could select and confirm to recover to factory settings, but after some seconds the boot loop appeared again with (seemingly?) no change having been made. The error kept appeaing over and over again.
After trying recovery mode, I attempted to start the phone in download mode by pressing VOL + on the (switched off) phone and connecting a USB cable. The respective menu also opened, here, showing "Firmware Update" and "Do not unplug the USB connection until the process is complete". According to many tutorials I found on the internet, when having installed the required drivers (I used LG United Mobile drivers from here), this procedure should allow you to flash a recovery image through LG's flashing tool (which one can also find on that page).
However, when I connect the LG G3 (D855) to a computer the driver is installed on, there is no new device shown in the Device manager. I tried this out with Windows 10 x64 and Windows 7 x64 and disabled driver validation on both systems and enabled test signing on Windows 10, respectively. Additionally, I followed these instructions, but in this case the screen stays dark and the device is not detected either. It seems like there are not so many people experiencing this error, but I hope we can find a solution.

This may sound like a dumb question, but have you tried a new battery yet? If it is one of the original batteries it could have gone bad & started bootlooping...like mine did a few months ago.
As far as the PC not recognizing the phone you can try downloading USBDeview and uninstall anything that has the vendor ID's of 1004 & 18d1(pretty much anything that says android or LGE in the description) & reboot the PC. Hopefully it'll recognize your device and install the drivers the next time you plug it in. If it doesn't find the drivers automatically for you then install LG drivers manually.

Link for LGE drivers: http://www.lg.com/us/support/software-firmware-drivers
Good luck :fingers-crossed:
I'm currently trying to follow this guide on how to install Magisk: https://docs.google.com/document/d/1fdeO9jmm8ewwRX_G0MaGHsVfIVtxgh0yRK0-Yypcl_E/edit"]https://docs.google.com/document/d/1fdeO9jmm8ewwRX_G0MaGHsVfIVtxgh0yRK0-Yypcl_E/edit (I can't make the link clickable since it's my first post) but it's in poorly worded English and I'm not sure if I'm doing it right. I've gotten into download mode by turning the phone off, holding volume up, and connecting it to a PC via a USB cable. As far as I can decipher, the guide says to reboot into bootloader through ADB from there. Thing is, ADB doesn't detect my phone being plugged in, but I know my PC detects it because LGUP detects it just fine. I've also tried booting into the bootloader by holding volume down while plugging into a PC, but that just turns on the phone. Doing adb reboot bootloader while connected and on just restarts the phone. If it helps, I did manage to get it into recovery mode through adb reboot recovery, but all I get is a 'no command' error.
If any of you Android wizards could help me out, that would be great!
You should reflash firmware ULM11g to bring back fastboot; after that read carefully before do something
Hey everyone!
So, I've got a HD1903, 8GB RAM 128GB ROM. I updated to OxygenOS 11.0.02, but it was still buggy as hell, so I decided to downgrade. I also had rooted the phone, and decided to get rid of that too. I went to the stock fastboot roms page, downloaded the 10.0.13 ROM and used 'flash-all.bat' file to clear everything. But halfway, it reboots, goes into recovery, then goes to Qualcomm Crashdump mode. That's it. No code or anything, just Qualcomm Crashdump mode, in Blue and Red letters. I tried to hold vol-up, vol-down and power to get into fastboot, but it just loads the fastboot splash screen, then goes back to the same qualcomm crashdump mode screen. Even if i try to hard reset it, by holding vol-up and power, it still goes to the same screen.
Anyone know what to do? I have no idea how to use the 'MSM tool' that everyone talks about, so any guiding advice would be great!
Thanks!
DM me here - https://www.facebook.com/prantor.khan.16 I'll help

I didn't install TWRP, this was all on stock recovery. I also cannot get into fastboot mode.
Msmtool does not need twrp or fastboot--just the software, rom image, drivers, and button combo pushes and holding
OK, so I got it working again, thanks to the advice of reddit users, discord users and the latest msm tool and some googling. I held the vol-up and vol-down buttons for 30 seconds, then connected it to the laptop, with msm running, to a usb 2.0 port, and pressed start. hey presto, it worked. Thanks guys!!

Hello
Using the MSM tool is very simple, you just have to download it from this link.
https://drive.google.com/file/d/12y3lO0wIgb2_LSDeVw9x_2C_HjbgZlb_/view?usp=sharing
NOTE: only works on Windows PC
1. Unzip the contents of the RAR into a folder.
2. Run the MSM application
3. Click Start.
4. Connect the cell phone in EDL mode (volume up + down button)
5. Wait for the process to finish (it takes a long time, please be patient)
6. The phone will restart automatically and a message will appear informing you that the equipment is damaged (don't be careful).
Note: The phone should automatically boot into fastboot mode and display a menu, but if it doesn't and instead boots to the T-mobile screen, you need to force shutdown with the power button for several seconds and then manually start it in fastboot mode. (volume up + volume down + power button)
7. Now you need to unlock the bootloader with the command from a Windows CMD window, but you need to download this ADB tool first.
https://dl.google.com/android/repository/platform-tools-latest-windows.zip
-Unzip the tool into a folder
-Open a Windows command window, in administrator mode and direct it to the path where you unzipped the ADB tool.
8- Execute this command while the cell phone is connected in Fastboot mode.

9- A question will appear on the phone in which you must allow the unlocking.
-With the volume keys select the option to allow it and press the power button.
-At this time your bootloader will be unlocked.
10. Copy the ADB tool files into the folder where ROM 10.0.13 is and replace everything.
11. With the phone connected to the PC, on the command line, run the flash-all.bat file
12. When the phone restarts and the yellow and white letters appear informing that the phone is not safe because the bootloader is unlocked, repeatedly press the (volume down) button until a menu in Chinese appears.
-PC will detect the phone again in fastboot mode and continue to flash
-Leave the phone and PC still until the process is finished.
-In the command line it will indicate that it cannot find files or partitions (ignore it)
13. Finally, the computer will restart automatically and you will be able to use it normally.
Notes:
1. If the phone after the flashing process with MSM starts up and shows the T-mobile logo, don't worry, just turn it off with the power button and connect it in fastboot mode.
2. Do not try to use it with the firmware that I install with MSM, as it will not work properly.
3. Before locking the bootloader again (if you plan to do so) first update via OTA, to the most recent version of Oxygen, otherwise the system will crash again and you will have to repeat the whole process.

Oh wow that was a long and well defined post. Thank you for taking the time to type it out.
As it happens, I fixed my issue already (IDK if there's a solved flair for XDA or something?). I downloaded the latest (10.0.15) MSM Tool from the XDA page, held the vol-up and vol-down for 30 seconds this time (as per advice from discord users) got the phone into edl mode, connected to a usb 2.0 port and let msm tool do it's thing. Everything is working perfectly now.
I've got the same problem but even with holding vol up+down buttons for 30 seconds I can't get into edl mode. It boots into qualcomm crashdump mode. I don't have fastboot working, I only see fastboot splash screen for a sec and then qualcomm crashdump mode appears. Could someone help?! As soon as usb cable is connected phone boots into qualcomm crashdump mode. no matter what I do.
Also do service centers undertake servicing for such phones which bricked because of badly flashed roms.

If they're going to just change the motherboard, I wonder what the EDL mode is meant for. Anyways, I won't go for motherboard change one can buy a new and better phone at that kinda price.
Anyways, I Fixed it through EDL method, you have to hold vol up and down simultaneously and immediately connect to windows (while still holding both buttons) via original USB cable. Check with Device manager if your device shows up, it's easy enough but you might have to keep trying to you get it right. Thereafter, disable driver verification in windows and if Sahara communications failed message appears in msm tool, turn off phone and repeat the procedure again.
The repair peeps only fix hardware and not software. It's more cost effective for them to swap out hardware faster than messing with msmtool like us

OK, so you won't get any confirmation that you're in EDL modem you just have to wing it. What I did, I first opened the MSM tool on my laptop, connected the USB side to the laptop at a USB 2.0 port, and kept the USB-C side within easy reach. I held the buttons down with one thumb for 30-35 seconds, and while still holding them down with one hand, i connected the cable to the phone and clicked enum in MSM, it showed connected so I let the buttons go, and it didn't restart. I clicked start, and it worked for me.

You don't have to hold buttons for that long, you can immediately connect it to PC. There is usually a sound to indicate that a new device has been connected to windows, you can also keep device manager open for confirmation. This video really helped.
After receiving a " qualcomm crash dump" , I was able to boot into recovery. Then I had done a factory reset.
Phone turns on fine, charges as well.
Although, On my Laptop / Desktop it does not see the phone within MSM, ASs well as ADB, Fastbootd or device manager.
I have the correct drivers downloaded.
Ideas ?

Tried both, my desktop would always connect, adb, fastboot, etc.
I had just just freshly installed oneplus drivers including qualcomm on my laptop. Device was not recognized before driver installation or after.
Figure id try on my Mac, and linux laptop. no dice.
ADB is enabled.
Here are the drivers that are installed on my PC ( I enabled hidden devices, in order to see them ) These were recognizing prior to " qualcomm crash dump" . Not phone will not even be seen
