Do you have a windows 7 PC? if you do, then you should not have any problem.. Phone will show up under com ports in device manager bit the com ports are hidden by default.. Further, you don't need to reset dates for lg flash tool, just search for megalock.dll file , google it...also google how to enable com ports in windows 7... You should be good to go

First of all, for that procedure and for the pc to work you need to get your phone on download mode (hold vol down button and connect phone to pc via usb cable). Are you still in bootloop? can you get to recovery?

just Google 'enable com ports in windows 7 device manager' and follow the instructions
Sent from my LG-E980 using Tapatalk

Try this.
In the part of the instructions where you disconnect the phone for 5 seconds, try disconnecting the phone, pulling the battery, and re initiate download mode (by holding volume up and volume down while plugging the USB cable into the phone). My green bar started moving immediately when the plug inserted into the phone. I've been trying to get this to work for the past 3 days. I hope it helps.

Root again, maybe you use restore backup app but not Rooted before.

Root it using "Root tool" application. Then install optimus G recovery apk from the forum...and reboot recovery . then use 3 wipes and reboot. After reboot connect usb cable.

I faced the same problem with my F180s.
To fix this annoying bug, just connect your phone via a USB hub.
Change your connection to anything like [MTP] or [LG software] (I prefer the later).
Then unplug and plug your cable between USB hub and PC, do this a few times and your phone will vibrate, which means that your phone is now connected.

now the phone full rooted, but the USB still cant connect to my computer. ady try other cable/computer, reinstall driver. it only detect slowcharging, not MPT option (ady change in setting-pc connection+enable debug too)

[Q] My G3 is Softbricked - $20 to the first person that can help me fix it!

I'm going crazy here and I need my phone to work!
I have an LG G3 on Verizon.
I rooted it and edited a part of build.prop to change the DPI which got the phone stuck in a boot loop and kept popping up "the process com.android.systemui has stopped.
I tried clearing cache
I tried booting in safe mode
I then did a factory reset
My phone boots up to the Setup Wizard screen but I am STILL getting that systemui error and a com.android.phone and I can't get any further than that screen.
I then tried to use the LG FlashTool to just wipe the entire ROM and replace it with the stock one from Verizon.
This gave me a "Model Information Check FAIL!" error but I DO have the right ROM for my phone. There's only one for the Verizon G3 as far as I can tell
This led me to realizing that there is something in the build.prop that's making LGFlashTool think the proper rom actually isn't right.
I then installed the Android SDK so I can ADB into my phone. but whenever I run "abd devices" nothing shows up in the list.
I was told USB Debugging needs to be turned on in order for this to work, I don't remember if it's turned on or not with my phone and I can't get past the Setup Wizard to edit anything. I wonder if ADB is even running properly on my phone or if these errors are stopping it?
I will gladly paypal someone $20 if they can get this working for me.

8) When the firmware is downloaded, boot your LG G3 into Download Mode. To do this, press and hold the Volume Up key and then plug the USB cable.

One of my friends saved his phone by this guide

Download mode - LG PC Suite - Restore update error.
1. Remove battery
2. Boot phone into download mode
3. Open LG PC Suite - restore update error
This method have saved me a few times.

Will adb work in one of the recovery modes even if it wasn't enabled in the full boot mode? If so, start there.

Regarding your USB debugging question, you would have had to turn it on in order to root the phone originally, right? If so I imagine it would still be on unless you unchecked it. You have the proper drivers set up? Anytime I've encountered issues with adb devices not returning any results the issue has been drivers.
Good luck.

What do you mean recovery modes? You mean like Safe mode? I actually haven't tried that. I'll give it a go.

I believe I have the proper drivers, I installed drivers and the phone is showing up in device manager as Alright.

Try hooking it up to the lg support tool and select uprade recovery.
Download and install support tool
Open tool
Plug in phone with phone on.
Top right select options/upgrade recovery

When you looked for phone in device manager did you change the port to com41? I forgot to do that and got the error in LG Flash Tool

Bro your motherboard is done with take it to service center

Oh man should've told you that. Sometimes its just a driver acting up and you have to manually delete them in the device manager. Sometimes there marked with a symbol .

No Download Mode!!

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?

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.

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.

d855 bricked?

I'm in a bit of a pickle...
Phone is dead, I'm unable to wake it using any method, however PC sees the device being connected. I have tried to restore TWRP backup which was completed correctly but then phone stuck and failed to wake up again. I have tried to unbrick it using the LG flash tool and dll +tot files however this method fails each time -with factory model check error - and download fail notification. Right now im waiting for kdz file to download (im using the tool checking my imei to select correct one) but it takes ages with my internet.
Anyone has any ideas? Am i doomed?

Hi
Happened to me also. I got out of it by using LG flash tool and clicking on options and selecting restore recovery. It puts it back to stock and you then need to reroot etc.

Options? On mainstream there isn't any. Is it on the 2nd screen after adding the kdz?

Current progress
Phone:
No download mode
No boot on the phone
Device acts dead - only visible on my pc (serial port LGE)
PID and IMEI not available to read using LG flash tool 2014
Tried
Loading KDZ file - connection failed
using tot and dll with flash tool - Failed to connect to device
Read something about laf.img using adb... Anyone has any other ideas? Funny enough when I was searching forums I was not able to find more info about cases when device is not waking up at all. but now i see few very similar threads around? Possible flaw somewhere?

Thank God it is showing a serial port, try flashing with LG tools 2014, let me find a fix for your download error...
EDIT: Is your phone by any chance plugged into a usb 3.0 port? If yes then please plug it in a usb 2.0 port and try again...

I hope you are right. Screens hots should be updated same link:

It might be the PC (work pc at the moment and some IT limitations on it) however drivers installed ok, software confirms that I have latest software on my device - when phone is connected to the pc. After running Recovery Upgreade, it gets problem with comunication between the pc and mobile. in troubleshooting asks to power on the mobile (which I cannot do) before retrying. Also I have installed LG usb driver from outside as options coming with this software seem to be for really old models?

A thing I tried with another G3 was to connect the phone to the PC without the battery and then insert the battery, disconnect from phone and then remove battery again then insert and hold volume up and connect the USB to the phone again and it went into download mode and allowed the use of LG support tool as before.
Its worth a try!!

No dice... so far. I'm back home in 2 days when i can try all of this again making sure that PC is not restricted from any functionality... although it does sucks to not to have a phone until then. If you get any ideas I'm happy to try it as well.. as not like i have anything to lose at this point.
