[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.

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

Kindly do help i know about android i just read silently but this time i am unable to solve it.

What system do you have on the machine that you're trying to flash the KDZ file? Did you install the LG driver?
I had trouble to flash kdz on my device from Windows 8.1 64bit. The flash would freeze after some time and nothing would happen. Try it maybe on another computer but after installing all the needed drivers.
Which software do you use to flash the KDZ file?

thank you for replying

I used the LG Flash Tool 2014 to flash the KDZ file
here is the link: http://www.mediafire.com/download/b2z1etctmettop3/LG_Flash_Tool_2014.rar
Type: 3GQCT
PhoneMode: CS_Emergency
It took me a few tries to get it working, it always stopped at 10% giving some silly error. I dont remember exactly what it was but after few tries it all went okay.
Hope it will help

I'm sorry but I really have no more ideas on how to help you. I did not have similar problems, I had a problem when my phone didn't want to boot anywhere except download mode. But the flash went through after a few tries.
Maybe you should try to flash it on a different computer? Install drivers and everything again and try to flash again. There may be a problem with drivers or something

I got it, done it

Please get back to me! Im stuck.

[Q] F240L Stuck at Download mode

Hi all,
I just tried to flash Android 5.0.1 kdz on my LG optimus G Pro F240L. The flash was unsuccessful, and all I ended up was with a Download mode. Previously It was on stock 4.1.2. I don't have any recovery installed. Please help me recover my phone. I just bought it (used) yesterday I tried different flashing methods but all in vain

It gives if you are connected to internet. You need to dc from internet then run LG flash tool. Once it starts flashing (after 5%), you can connect to internet again.

well, I'm going to sell it now.. I bought it used on olx and yesterday and today I found that it's rear camera is replaced with a third quality camera.... I'll buy Nexus 4 then
Thanks for Your precious time

Secure booting error on LG e989_0608

I have an LG e989_0608 which has this error.
It was purchased on ali express, so i am not sure about the info.
here is an example listing:
http://www.aliexpress.com/item/E980...48d8365fb7cf716-1459179376583-05342-eub6yrrBy
I am not exactly certain which device this is.
Some said F240, some said e988.
enclosed below are pictures of the error and the device backside.
I tried several methods of flashing, and nothing seems to actually get anything going in Download mode.
is there a universal img file for CWM\TWRP I can put on there the same way we did on samsung devices ?

By your description you have an e989. Then, go to Hyelton's thread in the general section, download the files for the e989. There you will find the instructions to flash back to stock using LG tool.

I'm not sure that's the same, but when I need to return to stock, after the extraction of the kdz there's an error.
However, behind the error screen the upgrading process continues. Is that what happens?

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?

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...
