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?

Did you install the drivers in the post? You might want to reboot the pc after install. What windows are you using?

just Google 'enable com ports in windows 7 device manager' and follow the instructions

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.

[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.

Did you tried this?

yes I did, that's where I got the "Model Information Check FAIL!" error

And what about this guide (if you can enter download mode):

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.

Hey thank, I haden't tried this but just gave it a go and the program is giving me errors when I try to restore update error. I don't think it's connecting to the phone.

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
Let it do its thing.

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

Hey everyone...it ended up being a stupid fix, I just tried flashing it on another computer and I didn't get the error? I have no idea why it worked.

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 .

one way :
there is a separate software that will download the firmware for you. Lg support mobile tool i guess (or google it) plenty of tutorial on how to install it from then on.

Yes it wont show. Its normal as your cell phone is not turned on. download the firmware manually by entering your imei or serial number/model no. Then install it. I dont have my pc and cannot recall the exact steps but its easy to figure out. Stay with the software use the available option . in doubt just google. You r just 10 mins away from fixing your problem. But downloading the firmware may take a while.

hold volume up and connect to pc -- download mode starts up?
if not -> connect to pc and see what happens -> also open up device manager if you´re on windows machine.

i did succeed, thanks to these!

Help! LGUP Unkown MODEL LG G4

Hey all, I think I broke my G4 h811 , but not at all because I can access to download mode, the problem is that when I try to open LGUP or LG flash tools, my LG appears as UNKNOW MODEL, and because of that I can´t install the kdz file, I tried to re install all the drives and so on, I am working in a win 10 laptop. Someone that can help me. Thanks!!! I will be waiting for a answer.

Enable usb debugging mod in settings>developer options. And also make sure that you have all the lg drivers installed and working. I am sure you will be fine.

Try using LGBridge and clicking the update error recovery.
You are coming from an international rom right?

change port number. or task manager adb kill

So using the hardware buttons, and clicking yes through the factory reset confirmation does not boot you into recovery mode? Did you format your internal memory?

using hardware buttons and clicking yes the phone just restarted and that´s it. I didn´t format my internal memory. I was trying to fix my phone by using kdz files but the problem is that the programs as lg flash tool and LGUP don´t recognize the model of my lg g4.

What firmware were you on? What message did LGBridge say when you tried error update recovery?

I have the same problem with my H815 and Windows 10. All drivers are set up correctly. In device manager, I can see the device and ADB Device, but LGUP won't recognize my G4. Obviously, LGUP is buggy...
Is there any better tooling to upgrade to a more recent ROM? Otherwise, I really would have to change to CM13 - upgrading is very easy and not any nasty USB stuff what in the end may not work at all...
