I am trying to go to download mode with my G3 ( mobile is working fine ) but when I press and hold Volume up and connect USB cable to PC, the phone turns on and boots normally.
I noticed even in normal situation if I turn off my mobile and try charging while it's off, it turns on automatically!
Any comments how I can go to download mode?
I have lost the original USB cable coming with the device. Can it be the reason? Is LG G3 usb cable special?

I use a diferent cable from the original and dont have that problem, can you try a diferent usb 2.0 port?
Is your G3 stock or does it have a custom recovery?
Try this:
Hold vol up button while connecting your phone to your pc

owh sorry I thought he said that he connected the usb and then pressed vol up :/
It's so weird to me. This is my first mobile phone with such a problem. I've tried all possibilities. USB 2.0, different cable, different pc, different OS. All I get is a restart when I hold down the up key and connect the cable! I have bought this D855 from Hong Kong and it's on rooted stock 10b and all I get from my 4G sim is E (EDGE) while I have activated lte in mobile network menu. So, trying another official rom is critical to me.

It's on stock as without download mode, I can't flash any rom or recovery.
It's more weird when even ADB can't send phone to Download mode. When I enter "adb reboot download", mobile is only rebooted.
By the way, I wonder if it's also so for you that when phone is off, if you connect charger, device is turned on! I remember when I had Samsung, when mobile was off and I connected charger, a battery icon showing the charge progress appeared only.

I asked about what recovery you had.. cous I had a similar problem with my samsung s3.. when phone off and conect cable the phone starts up. That depended on some bad recovery. Also on my old Htc desirehd things like that happened. But i dont have any deep knowleage about this..
Have you tried to use Lg's official update tool. Under that app you could update phone after a bad update. (Via the menu in app) It would be my next try.. that resets the whole phone but it could be the cure. Take a backup of the internal sd first.

Are you referring to this tool? http://www.lgtool.net/site/download.html I downloaded this and when I run it, it asks for a missing smartcard!!
If not, please offer me a link to your mentioned tool.

No.. Go to the lg website. Go to support and navigate to lg pc sync app. Dl that app.. About 200 mb.
Install and look for the earlier mentioned option.
You can also reflash the download mode partition with dd if you are rooted.

Hey everyone. I was hoping you could help me.
My N7105 was softly bricked to I downloaded a firmware and flashed it, but I didn't realize it wasn't the right (Portuguese) version. Therefore I had no cell phone service.
I now have the right firmware, but the phone is no longer recognized by the computer
I've reinstalled the drivers and Odin and I've tried USB debugging. I've also tried another cable and it won't work. The phone simply isn't being recognized by the computer!
I have no way to flash the firmware and I don't know what to do
Help, please...
Thanks so much

This worked for me. Hope it works for you.
Go to download mode. Plug into USB port. Remove the battery when plugged in. And reinsert it. Odin should recognise the phone.
If your mobile switches off, retry a couple of times. If it still doesn't work, you might have to use some other computer.
Press thumps up if you found this suggestion helpful

Thanks for the feedback
Unfortunately I've tried that and it didn't work. I've also tried installing everything on another computer and trying there. Still no response.
Any ideas?

Try to flash your firmware using mobile Odin. It should do the trick. As far as I can tell it seems that the cable or port of ur phone is damaged.
Hi, I tried to flash 20b through twrp tonight.
I did factory reset, then flashed the bootstack, then flashed the system. But after that, my phone won't power on. I tried to remove the battery, holding power button for a long time, or power+volumn down.
The phone just does not respond at all. Can anybody help? Thanks!

take the battery out and put it back in and try to power it on. Repeat a few times, if that doesn't help we'll try other things.

when I had that problem I figured out that it was the battery that was making the phone act weird. Since LG sent me another battery when they had the promotion I used the other spare and that fixed it for me.
This happens right after I flashed the new system, I doubt it is the batter problem. If I plugged into the computer it still won't power on.
(If I remove the battery and plug into computer, the screen of the phone does show some symbol, probably regarding missing memory).
Let me try to see if I use kdz flash to reinstall the system. Thanks for the help.

No it just shows regular LGE com port and I am not able to flash anything. You are right, it's hard bricked I am not sure what went wrong with my twrp flashing procedure though. Will contact with LG for repair.

This is why You don't flash the boot chain unless you absolutely must. I was running 20B with the old boot chain (other than rpm, that was updated) and it ran just fine. If you get a bad flash on the boot chain your sol.
I have a D852 (Koodo) that just refuses to get into download mode.
The issue is that "download mode" flashes on the screen for a second, but instantly the screen goes black and the phone reboots, leaving me to believe there is some sort of file system error. However, I can't fix it by flashing stock .kdz because of no download mode!
Have tried, so far;
Different USB ports and cables, both 2.0 and 3.0
Reinstalling drivers, different computers
Restoring with LG PC software (failed)
Question is basically, is there a way to reset it without download mode working?
Any suggestions? Phone works completely fine otherwise. Is flashing a .kdz doable with adb commands?
Thanks in advance!
Having same problem.

Completely forgot how to enter download mode on LG G3. Power off , hold volume up and plug usb in pc.
I flashed Fulmic rom for my G3 D855 today. Everything was well when I discovered until I discovered, that camera app is not showing. The fix was to download the fix from Fulmics app and flash it via TWRP. I downloaded the fix and rebooted to install the fix. After reboot I got stuck in bootloop, when I try to access recovery, it goes to TWRP first logo and stays there. Nothing happens. When I try to access download mode, it shows the first download mode logo and stays there. Computer detects the phone in device manager as "LGE Android MTP Device". LGUP shows model as "Unknown". Cant do nothing more. Every help is appreciated.
Are you sure you flashed the fix ? Because it seems like you flashed something else that messed up your device

I downloaded the fix, then tried to install it via twrp. But twrp didn't start. So I ran AutoRec again to reinstall TWRP which seemed to go well. Forgot to mention this on first post. After reinstalling TWRP the problems occurred.

Can't enter twrp, just shows TEAMWIN logo with blue background and stripes. Nothing more happens.
Download mode text shows up, pc makes connection sound but I dont know what to do after that. I tried using LGUP but that showed that model is "Unknown".
Ah, try lg flash tool 2014 or lg flashtool (and a tot file), find a thread by hyelton (lg g3 get back to stock), this will help you

I have tried this method also. Every time at 4% it says, error, remove battery and then reconnect and turn on phone. After that, connection with pc is lost.
Also, when I try to get to Download Mode, it should go then to Firmware update screen to? Am I right about that? If so, then it doesn't go to Firmware update screen.
But I tried it with a kdz I had in my computer and had used before. Downloading .tot file atm.

Also it stays in download mode screen, not Firmware update screen. I don't know if this affects anything.
