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.

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?

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] LG G3 without connecting more !!!

Hello friends,
I come across this forum as conceptualized ask for help to solve a problem I'm experiencing with my LG G3. I have a LG G3 D855 asiatica oringe and how much like customizations made ​​some changes, nothing that had not already been done on other devices I've ever had and never had a problem. Once you have downloaded the root Xposed, and some modules framework, using usually came after that, more to my surprise when making a frustrated attempt to install a font that I downloaded from this forum and try to install the app IFont, I realized that the machine began to take much to restart and the worst is that this delay was increasing and even though I desistalado some applications and the source itself, I realized that this delay only increased. Just to give you an idea, the last time I tried to restart took 48 minutes. I tried to go into recovery mode in various ways, in no more managed to get him into recovery. I tried to restore factory settings through and he was not called for more black screen and only the LED flashing blue and red. Please if anyone can help me I earnestly beg you pass me an email: [email protected] or answer right here.
Grateful.

try to get into recovery by powering the phone off. remove and reinsert battery. plug USB lead into USB 2 port on the computer. press and hold the volume up button. keep the button pressed while you plug in the usb lead to the phone. that normally gets in to recovery. (does not always work with a USB 3 port for me).
then flash kdz in "normal mode" using the instructions in another thread. or use the LG more support tool. (sorry, not able to search for the correct threads at the moment, need to log off for a couple of hours...)

Even following the tutorial restoration via KDZ not had success, catering to more starts in less than 2% of a message to retry, or my device is stuck without being able to restore even via KDZ, does anyone here know of one restuara hint how the recovery mode LG G3?

you might want to do a clean reinstall.
Download the KDZ file (V10h or V10j) and try with the CSE flash option in LG flash tool.
boot into download mode (hold power up and insert USB into PC) and then hit CSE flash.
even if the tool says it's done, just wait - do not click Exit. The phone might still do the upload (check the progress on the phone itself).
Be careful about the version of the KDZ file you download - do not use a 16 GB version if you have a 32 GB phone!

Well folks,
I have an LG G3 D855'm having a problem during the restore process via the LGFLASH TOOL, follow the tutorial step by step over when it will begin restoring is no more than 2% and always the error message "retry", has changed the usb cable and the error still persists, you will not have to help me?
Grateful.

maybe you can try this?

an extensive list (albeit not complete) is here http://forum.xda-developers.com/showthread.php?t=2791761
I haven't seen any Brazilian ROMs and I'm not sure if flashing another region would affect 4G reception or not.
Your best bet is to try via the LG PC suite (link with tutorial in my previous post) or get the KDZ for you phoe from LG site:
http://csmg.lgmobile.com:9002/csmg/b...2.jsp?esn=<IMEI HERE>
You just need to replace the red text in the link with your IMEI (it is on the box or invoice).

Can't use LG Flash tool

I tried to flash latest 10L firmware, but I always get the messages Problem with communication between cell phone and PC. I did everything as instructed, selected Normal flash, but it won't work. I installed needed drivers, but when I reboot to Downloading mode, there is Exclamation sign in device manager. What could be the problem?

Did you change the port to com41?
Also are you using windows 8? If you are you need to disable signature verification.

I don't know how to change port to com41. I am using Windows 7.

It's in the guide that you said you followed. Open your device manager in windows and right click on the lg device that shows up. Next hut advanced and change the port to com41 and then click ok.

I did that, and it still shows the same message.

Bump.

Did you install the latest LG drivers for your phone? I don't know why this didn't occur to me earlier but that plays a big part in the PC seeing your phone.

Yes, I have driver. PC Suite works, everything works, but Flash tool doesn't.

Could this be connected with bump twrp. Maybe it is blocking this somehow.

You've got to boot into download mode and then use the LG FLash Tool 2014. There's one error stating there is an error with a connection, just ignore it and watch your phone screen! If it tells you stuff like the current version and the version it is about to install, just let it sit and wait till it reboots automatically.
The reason I am saying is because you say "Problem with communication between cell phone and PC" and it looks like the error that is supposed to show up.
Could you please re-do the process, maybe re-install the LG drivers and use LG FLash Tool again. If you encounter any error either make a screenshot or type the EXACT error message in here.
Good luck

I solved the problem.

For all who is experiencing the same thing problem is in 64bit OS but it is not a rule. People reported that they were succesfully flashed their devices on win7 x64. If you want to be sure use x86 windows and it should be working.

Help! I think I bricked my LG G3 and now I am in a boot loop!

I decided to downgrade my LG G3 D851 from Lollipop 5.0.1 to the stock firmware.
I followed all of the steps of to downgrade my LG G3 D851 to the tee.
Towards to end, you have to restart your phone at the blue screen, this is what I did by taking out my battery when the big red "3" came up. It looked like it worked fine in the video right? But, to my luck, it just created a boot loop that I cannot get out of.
The reasons that I cannot get out of this boot loop are:
1. Because the LG G3 is so messed up, my computer will only recognize it as an unknown device even with the drivers installed.
2. The only way as far as I can see right now to fix it would be to follow the steps of the SAME video that caused this.
Any solutions guys?
Sorry if I am being vague, I'm kind of new around these parts and to rooting. If you need any answers I can surely provide.
Thanks!

Okay see if you can cancan get ti download mode. Take out your battery, put it back in, then hold volume up and plug in the USB. You should see a firmware update screen. Once there use lg flash tool to flash back to stock via kdz or tot.

Hey! The reason that the boot loop was created in the first was BECAUSE I tried to flash back to stock. Also, even if I did try to do this, the PC would not recognize the device and would register it as an "unknown device" even if I have LG G3 drivers.

Do you mind sending a screen shot of what you see in the computer? Does your phone still go to download mode anyway?

Do you have access to a computer with windows 7 or possibly 8. From what I know WIndows 10 is not supported by lg drivers yet. This could have resulted in your brick, however you can try to uninstall the drivers and re install them.

should try running the lg suite on your win 10 machine in compatibility mode for an older windows
