Lg v20 download mode help - LG V20 Questions & Answers

Hi, my screen does not turn on, i can feel vibration when it is turned on, i am trying to put it into download mode holding VOL- button and using usb cable, but not working. (it worked before)
Anyone can help me with how to put it into download mode so that i can flash stock firmware using LGUP.
As screen is always black, i cant tell anything.

Did you check to see if it was detected by LGUP? Power it off, connect USB cable to PC, hold volume UP with phone still off and plug in the cable to your phone. Release a few seconds after the phone vibrates to be sure it got into download mode. LGUP should detect it if it made it to download mode successfully. I would also be sure your battery is charged before doing anything.
Do you know what caused the screen to stop working or remember the last thing you did before it stopped? Perhaps there's an internal hardware issue.

[Q] phone to pc screen :(

dont kno if im posting this in the correct section or not but can some one plz help? i was trying to flash the stock files for my samsung vibrant with odin, but it froze so i unplugged and tried to reboot my phone but the phone to pc screen came up. ive tried holding the volume buttons + power to get back to download mode, but it just reboots and goes back to it, can anybody help?
Did you hold the power button down till it disappears and then release the power button immediately as it disappears?
hadnt tryin releasing the power button right away but i just tried and still no luck
Johnz is right. To make sure, unplug & plug back in the usb cable, then hold down the volume keys & power, wait till the screen flashes to black, then release power.
Unplug and pull the battery.
Install battery.
While holding both volume buttons, plug in usb cable.
Have odin ready to go, it seems to help. The phone should power up directly to download mode, once odin sees it, hit start.
i dont get what im doing wrong because ive tried what u guys said but after the screen flashes black when it comes back on its the phone to pc screen. ive also noticed that if i pull the battery while the usb cord is connected the phone stays on at that screen until i remove the usb cord, is that normal?
i just read that if the normal ways dont work that means ur phone is hardware locked. looks like im gonna have to try to send it back to tmobile and hope for the best
Try the above, but also hold the home key. I did the exact same as you, and this enabled me to get back to download mode, so I could Odin.
1) Remove battery, SIM, and sd card.
2) Plug in USB Cable.
3) Hold down Vol +/- as well as home.
4) Press power button for 2 seconds, then release.
This should get you into download mode. Then you can Odin back to whatever you were intending to do.
thanx for all the help guys but nothing seems to be working for me
Just throwing out an update incase anyone was wondering, I got my replacement phone yesterday and it turned out to be hardware locked as well. Tried to flash the fix for it and it failed and bricked my phone! So after calling tmobile they will be sending me another replacement and hopefully that one wont be locked as well
I had the same problem trying to get into Download Mode, I got into download mode and using ODIN tried to flash update. The process was stick for 10 min.
So I unplugged USB and got this phone to PC icon. All I had to do to fix it was to go into download mode again by holding both vol +/- keys and pressing power button until screen goes black then release the power button as soon as the screen went black. If you hold the button longer it will go into recovery mode. Then open ODIN again and re-connect USB and ODIN will detect COM port. However you have to make sure that all samsung usb drivers are installed. That is it. Then flash the update and you all set. The phone will reboot and you are back up and runing.

there is another way to this method, that works on any vibrant i've tried it on and also the captivates, had to help a friend restore his yesterday.
remove battery, sd and sim cards
plug in usb cable to pc and phone
hold down the volume buttons only
pop in the battery
if it comes up to the battery charging icon, pull the battery and put it back in again, should go right into download mode.
again, this works on any vibrant i've tried it on, and the captivate as well, good luck.

You have to flash your mobile with correct rom.
Turn your phone completely off, then Turn it on by press vol down + power button then you will see download mode >> FIRMWARE UPGRADE screen then follow this method "How to go back to stock"

Unplug usb from computer.
Try to power off ( holding power button for some time. Don't leave power button again if lg logo appears.)
Phone Will be off now.
Now hold volume up button and plug the usb.
You should get download mode.
**your usb port may be loose.
Don't shake usb cable while flashing using lg flash tool.

I know how to get into the download mod problem that the device no longer enters no matter what way I do it
Did u select cse flash while flashing kdz file?
What do u get ?

Cannot unbrick [cannot enter EDL mode]

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

Thanks for your help, folks.

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?

Galaxy A40 infinite loop - impossible to turn on

Hi!
I have a problem with a galaxy a40 device, I flashed a stock ROM with Odin, everything went fine, green lights, PASS and all, but now the device just won't go pass the SM logo anymore. When I turn on, logo appears 2-3 secs I get a warning of the unlocked BL then logo comes back and after a second the phone restarts itself and the same goes on forever ( well about several hours, and after that it just shuts off somehow ). I cannot enter recovery mode or download mode at all. I keep pressing the combinations Power + Vol Down, Power + Vol Up, All three and every combinations I have just found on the internet so far. Odin doesnt recognize the phone, which is not a surprise since it won't start up. I have tried with adb but waiting for device is all I get.
How is it even possible that I cannot enter download mode at all? There was no problem with the physical keys, and the power still works, I cannot test the Vol buttons tho.
Has anyone ever had a problem like this? How can I come back from this? Is there a way to flash a ROM without download mode or turned off phone?
Thanks for any help!!
The download mode for this model is different from previous Samsung's :
IIRC, with the phone off, you need to hold VolumeUp and VolumeDown, then plug in the USB cable connected to a computer (you may need to press Power to power up the phone, I can't recall properly).
From there, you should be able to restore a stock ROM with Odin.
Let us know if it helped !

Here the same problem, have a40 in loop and never get rocgnized for computer, tryed many different cables, and installed a booring large amount of drivers software and nothing...
you need to power off device completely. let battery drain if you can't shut down. press and keep holding volume down + plug in usb cable for Odin3 (I doubt both?)

Generic answers, repeated 800 times why really need to waste a post with that? and that not was the problem:
1- For no usb recognition, is this phone bad design, in the back tap where is the battery in the samsung logo more or less if you push with fingers and charge is because the design of baterry is so crap and your usb port goes off when the under tap cable moves or just get little out of conection. If you can get working after push, usb on phone will do too.
