Unable to enter download mode - G3 Q&A, Help & Troubleshooting

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

[Q] Download Mode / USB Drivers not working

Hey there,
I press volume up + insert the USB, when the LG screen appears I let go of the volume button and leave it. After roughly 1 minute it says Download Mode however it only stays in this mode for roughly 20 seconds and then it goes into Fastboot mode saying "reset" and "changed port". I got the correct ROM for my IMEI and LGFlashTool however I think the main problem could be the LG USB drivers. When I try install the official drivers the installer says success however windows says not successful.

I have tried uninstalling all LG drivers/software, restarting etc.
I am fairly sure I can flash if I can just figure out how to successfully install the drivers or connect the phone to the PC. Anybody have any ideas? I can use linux or try any suggestions/alternative software.
Kind regards,
Desperate G3 owner
Just an update that I was able to manually apply the LGE PORT/COM driver in device manager however the PC only recognises the device when it is in Fastboot Mode. When it starts in Download Mode as stated above, nothing happens, but after ~20 seconds it will automatically switch to Fastboot Mode and then the PC will detect the phone and says Fastboot Commands.
I have tried using adb.exe devices and fastboot.exe devices in cmd but nothing shows up, any ideas?

PC does not recognize my phone, and can't enter download mode [Cyanogenmod]

I recently installed cm12 on my phone after a long time thinking it was bricked. However, I want to switch to stock firmware now, but I can't make my pc to recognize the phone, and I can't enter download mode, so that means I can't flash it back using LG flashtool. I've installed LG drivers several times, tried 2.0 and 3.0 usb ports, native and others usb cables, but nothing seems to work. As for download mode, I press the up button while the phone is off, and when I connect the usb, it shows the battery image, and it stays there.
Any thoughts?

G7 detected by LGUP while in download mode, but not detected by ADB

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

Question Oneplus 9 pro bricked, impossible to get to EDL

Hey all,
So i've unlocked by bootloader, flashed a custom recovery to then proceed with LineageOS flashing. However it went completely wrong as on reboot i'm stuck with the bootloader unlocked warning and then a blackscreen.
I still have access to fastboot mode however it's impossible to flash a customer recovery ("No Such Partition") and also impossible to directly "fastboot boot recovery.img" as the phone simply reboots on the warning and then blackscreen.
The only solution seems to get the device to qualcomm EDL mode and reflash all with the MSM tool (which I have as well as all the drivers) however I cannot get my Oneplus 9 pro to EDL mode...
I've tried all the fastboot commands (fastboot oem EDL, fastboot reboot EDL, none of them work) as well as the combination volume UP + volume DOWN + plugging the cable (it just boots the fastboot mode.
Honestly would greatly appreciate any help as it is the first time in a decade I hard bricked a phone like this as it seems all the partitions are broken.
Make sure you have it unplugged when you do the button combos, as it will just start to boot while it's plugged in. Also, if you can reach fastboot, you can almost definitely reach EDL. Try unplugging and holding power+vol up for a bit which forces it to completely power off. Then try getting into EDL through the normal button combo/plugging. This is what I had to do since once it got into the booting/no-booting cycle I couldn't get to EDL.
1] Make sure you have it connected directly to your computer via USB port rather than via a USB Hub, I've seen that cause the device not to show up in the device manager.
2] You might have to restart your computer with driver signing disabled, check here for instructions for that
3] I've uploaded the Qualcomm drivers here
4] Make sure you use POWER + VOL DOWN + VOL UP and watch your device manager to see if the device is there
5] Make sure you choose the correct MSM tool from here for your region/provider
6] Remember to use MsmDownloadTool V4.0.exe, choose "User type : Others" and choose the correct device/region under the top "Target" dropdown.
7] If you don't see any COM device showing connected then try changing USB port or rebooting the device back into EDL mode.
Good advice above.
Last time I couldn't reach EDL with my previous phone, it turned out to be an issue with the drivers I had installed. I uninstalled all Android-related drivers including some generic thing that showed up in device manager when plugging in the phone, then reinstalled the latest Qualcomm drivers.
Also possibly try a different USB cable if you have one. My OP9P didn't show up when the cable it came with was plugged into my USB-C port for some reason, but it worked fine with a generic Type-A to C cable I had sitting around.
Thanks a lot for the different guidelines !
i'm 100% sure the drivers are working. I have another oneplus 9 pro that is detected when booted on EDL mode on the PC. The faulty one however cannot reach it. Also it cannot get any charge as whenever I plug it on it just goes on a boot loop. Tried to leave it to charge for a full night but still shows the "out of battery logo" with the red cable.
When plugged to the PC while pressing VOLUME UP + VOLUME DOWN I keep getting the windows sound of device plugged/unpluged, etc etc...
To be honest I think the flashing messed up the partitions as it is now hard to do anything with this device...

Can you help me too, I have exactly the same problem…
If you use Windows, you need to see "QDLOADER 9008" in Device Manager > Portable Devices.
When you got this it will work, 100% .
It worked for me a few days ago. My laptop runs on Windows 11 x64. And only have usb 3.0. NO usb 2.0.
was having the hardest time as well, it's not that the device wasn't going to EDL mode, it was but it had the wrong driver installed, thus making MSM tool not detect it in time, it is a very small window that you have where the device goes into EDL mode and the MSM tool detects it, makes a handshake with it and starts the process, but if you have the wrong driver, MSM tool will not detect the device and the device will just turn back into fastboot mode, I'm attaching a picture of the device manager where the said driver is under "Ports" ( COM & LTP ) make sure you download the above mentioned drivers, if there is any other driver under Ports, uninstall it and whenever you plug in your phone with the VOL + VOL - combo, you will see the device appear under PORTS, upgrade the currently installed driver for the one called qcmdm.inf which you'll find after you extract the .cab file that you downloaded previously, after that open MSM Tool and hit start, the port number should match the one on the device manager, now unplug the cable from your phone, power it off and do the button combination and then plug in the cable, MSM should instantly recognize the device and start the restoration.

Yeah make sure it's exactly the same name of that driver - worked for me on oneplus 9
If you have access to fastboot still. Try switching slots. Then going into EDL

Thanks a lot man. Saved my Day. First 9Pro successfully restored ;-) Thank you and merry Christmas to all.
Guys I do not need to use the MSM Tool Anywhere until I reach the step where my device is being successfully detected as "QDLOADER 9008" in my windows device manager correct?
Or does the MSM Application need to be running when I reboot to EDL mode?
I am following this guide.
Please help
I always have phone powered off, and while holding both volume keys I plug it into USB cord(that is already plugged to pc) and then click on enum(button in msm screen) until it says connected then hurry and click start. Once it starts I can let go of volume keys.. Also more than likely u will need to click the box to "use lite firehose" or "Sahara communicaion" will keep failing.
make sure you have oneplus 9 pro drivers and " qaulcomm incorporated - Ports" Driver) and ("qaulcomm communications inc-Net" Driver) so your phone in edl which will be already most likely be running before you plug it in. just hold down both volume buttons and plug in to the usb port to your pc and release once plugged in and start the msm tool and hit enum it should say connect provided that you have all the necessary drivers above so the pc usb port will be able to communicate/recognize you device. its never usually A 1 and done type of thing. everytime i brick my phone its always the 100th try before i get a com port connected and the software communicating successfully, so just be patient and take your time. you will get it back up and running,
Hey, I wanted to ask in here instead of starting a new thread.
Right now I have an OP9p that wont boot to EDL (Only fastboot or Corrupt page)
I tried the fastboot commands but it won't work and it won't shut down, I have fixed multiple phones using MSM and know all the small issues and how to get around them but it's the first time finding a device that won't shut down and will keep rebooting tried volume up + Power for several seconds tried holding only power or the three.
Nothing it keeps rebooting and won't shut down for me to get into EDL.
Any ideas?
Thanks

Well you have a corrupted boot.img or you would not be trying to edl. Also you probably are holding down multiple buttons to power off to your phone and your either not remembering or forgot that these combination of buttons are booting you into other modes fastboot, recovery or system.

Question Need help unbricking -> EDL not accessible for MSM

[SOLVED see post below]
Hi all,
Just bricked my Phone and can't access MSM. Hope you can help me. I will try to be very clear on the steps I took to get to this point.
Device: EU OnePlus 9 Pro
What is was trying to do: Go from rooted C.47 to Pixel Entended ROM
What I did:
Code:
Unrooted using Magisk uninstall option
Updated to c.48 through OTA
Go to lineageOS page on how to ensure all firmware partitions are consistent
very stupidly did not flash dtbo and vendor boot partition
did adb reboot fastboot in stead of abd reboot bootloader
Download the "lineage-19.1-20220701-recovery-lemonadep.img" and tried to temporaryly flash it by
fastboot flash boot <recovery_filename>.img
This resulted in the device getting stuck on the 1+ boot logo.
I can still force turn it off by holding Volume Up + Power.
When I try to access EDL by turned off and Vol UP + Vol Down + Plug and release, My PC makes a connection sound and the screen stay black for a while. After +- 10 seconds, the PC makes a disconnection sound and the phone boots up and gets stuck again on the 1+ bootup icon.
Also my phone won't stay turned off when plugged in the charger or pc
Yes, but what is it presenting as (i.e. EDL, fastboot, ADB, UMS...) when it connects?
If this is Windows, UsbLog.exe is handy to identify things popping up (as long as they have drivers installed).
For a list of devices that have ever tried to connect, try "enumusb.exe /l".
Both available here: https://www.temblast.com/windows.htm

I will try this
I found the issue:
> EDL exits after 10 seconds if it is not captured by the MSM tool.
> The MSM tool only monitored 4 of my 10 USB ports
> So it was not captured because I was plugged in to an unmonitored USB port and rebooted after 10 seconds
> I have successfully used the MSM tool now
Oh! A bit off-topic, but I have never understood why EDL is commonly used over a "serial" port.
The interface that EDL presents is a generic USB bulk interface with two endpoints. You can use it just like that.
But no. They have to use a Qualcomm driver that makes it look like a "serial" port and then you can connect to that.
Me? I use a generic "WinUSB" Zadig driver. I have an EDL client that just connects to that fine.
So does the Python client implementation.
Also, I've never run into that 10 second timeout.

Your phone needs to be in OFF state mode when you're using EDL.
So, very simple:
Enter bootloader mode by holding both volume buttons with the power button together till your phone restarts and enters the bootloader.
From the bootloader screen you can use the volume buttons to navigate through the choices and you can select "Switch off".
When you complete this, you need to hold both volume buttons, and while holding them connect the cable (PC).
If you don't have or you don't have the correct Qualcomm EDL drivers installed, your phone will reboot or start to boot, it won't stay in EDL mode for longer than 10 seconds.
I also got the correct drivers for you, but you need to install the drivers manually while your device is in "EDL" mode, so, you need to be a bit "fast".
I have even a video for you, but need to upload it to YouTube so you can watch it.
I'll share you here the drivers just in case if you're familiar with a manual installation of the drivers.
