Right now I'm following a guide to unbrick an Optimus G. Downloading the FW is the first step. It doesn't seem so difficult. If I manage to unbrick it, I will share step-by-step guide here.
I'm f***ed up! Nothing works. Who can help me really I want to kill myself.

While pressing both volume up/down together, connect your phone to pc via usb. Open LG Mobile Support Tool. From options, choose upgrade recovery.

As I recall, last time I tried, it can't find my E988 through USB.
I did install driver before I connected the phone.
Any other setting required?

As I told you, you need to be on download mode. Follow these steps:
1) Pull out the battery. Your phone will be turned off
2) Insert the battery but the phone shoud stay turned off. Plug usb cable to the phone but not to the pc
3) While the phone is off and battery is in, press both volume up and down buttons together (Do it with your single hand)
4) While you are pressing the buttons with your hand, plug the usb cable to the pc with your other hand.
5) You should see phone gets into download mode (DOWNLAD will be written on the screen)
6) Now the pc should recognize the phone.
7) Open LG Mobile Support Tool
8) You should be able to see that it recognizes the phone. If it doesn't, repeat the first 4 steps when LG mobile support tool is open.
9) After your phone is seen by the pc, choose Upgrade Recovery from Options.
10) It will check the FW from internet by using the imei Number of the phone or you can enter E988 and your serial number manually
11) Then it will download the FW and recover your phone. It will take time according your connection speed.

Thank you. Finally, Mobile Tool detected my E988 and is downloading the firmware now.
Something wrong with my Win7 , it just can't find the driver for E988.
Then I open XP mode in my Win7 and try again. The phone was detected and Mobile Tool open for action.
Thank you again. My E988 already bricked over a week.
I need fast help pls.
How I can update firmware via USB on ma P6?
Device is now dead, everything I have is recovery but I cant install firmware from SD card because it doesnt work.
I want resolve this problem until my baterry dead.
Can enybody help me?
Hey Salonko
You could try downloading Odin (you can find it on google) and a stock firmware (if youre not findi g anyone just pm me cause i live in cn). Then you bring your P6 into the Download Mode by pressing Volume Down + Power Button. Then just connect your P6 over USB and Odin will find your phone. Then you select the Datas from the Firmware and flash them to your phone and Voilá! Your Phone is brand new!

I'm rooted and have made a have few changes to my phone in general, but now it won't start up. It gets past the LG logo but then gets stuck at a black screen with the LED's cycling colours.
I've tried to factory reset it but it still gets stuck at the black screen. How do I fix this?
I has this a few days ago.
To fix it you will need LG mobile drivers and LG PC Suite installed.
Power off your G3. Then start it in download mode by holding the volume down button and connect a USB cable to your phone. The screen should show download mode. Connect your phone to your computer and start LG PC Suite. Don't worry if PC Suite doesn't recognise your G3. Go to the mobile device menu and select restore upgrade errors. PC Suite should download the latest firmware and install it. You will be back to a factory reset but your G3 will be working again ☺

I tried to fix the update errors but it said this update is not supported by Mac OS. I don't have a windows PC to use so what can I do now?
I don't have a Mac so not sure if this will work but search the G3 forums for advice on flashing a .kdz firmware directly to your phone. Make sure you find a .kdz that matches your G3 variant i.e. 16 or 32gb. Sorry but don't know if there is a Mac tool to do this. Good luck.

Thanks, Ill check that link out.
I'm finally on a PC and went into download mode but now my phones stuck at 0% doing a firmware update. It says don't disconnect the USB until the process is complete but I think I'm going to have to
When I did click fix software errors it said there were no errors to fix but I don't think I have all the drivers installed yet.
When I try go to download mode it keeps taking me to the firmware update screen and stays at 0%. Also the drivers aren't fully installing on this computer for some reason.

Install the LG united mobile driver first then LG PC Suite. Might be useful to reboot the Windows machine after that. Try having PC Suite running when you connect your G3. PC Suite might nag you about being unable to connect to your G3. Just cancel that and select restore upgrade errors. PC Suite should download the latest firmware before it flashes it to your phone. Check that your G3 is in download mode before you connect it to the Windows machine.
I'm assuming you've checked obvious things like turning off any firewall software that might block outgoing connections...

Tried those things too...for some reason the pc could only download 2 out of 4 drivers. Also my phone wont let me stay on the download mode screen. It comes up for around 2 seconds then just goes to a firmware update screen.

There are drivers and PC Suite for Mac on the LG website. That was all I needed to recover my G3 on my PC. I would try installing the unified drivers and PC Suite again. Start up PC Suite. Put your G3 in download mode and connect it to your Mac.
If that doesn't work and the unified drivers and PC Suite won't install on your friends Windows machine then I would run chkdsk and the system file checker.

I've got the drivers and PC suite for mac but anytime I try to 'fix update errors' a message comes up saying 'cannot run updating. Check device status and retry'. Then when I update the suite to the latest version, the 'fix update errors' option disappears from the menu. Ok I'll try those out on my friends PC when I have the chance.

I've got an LG G3 by US Cellular (US990) that I'm trying to downgrade using LG Flash Tool. The problem is that it's not being recognized by Flash Tool or by LG PC Suite for some reason. When I plug it in in normal Android it recognizes it whether it be charging, MTP or PTP. But when I go into download mode these programs do not recognize it and so I can't flash anything. Anyone had any similar problems or anything I can try? I have installed the drivers multiple times and I'm on Windows 7 64 bit. Any help or suggestions are greatly appreciated, thanks!

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.
