Bricked my phone :(

I have the ATT model of LG Optimus G Pro E980.
Today, I rooted my phone and everything went smoothly as it usually does. Everything seemed fine until i tried flashing this http://forum.xda-developers.com/showthread.php?t=2428207
Now I can only boot and get a LG screen and then it just turns black. I got into download mode maybe once or twice but I can't repeat it and the device doesn't seem to show up on my computer either way. I booted into CWM maybe once by smashing keys and it just randomly popped up but its also not repeatable . Any suggestions, I'll honestly try everything.
Thanks

At the moment I'm only able to get to the lg screen and a screen that shows a battery (plugged into the computer)
Any suggestions?
Oh and also I'm able to get to factory hard reset.

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.

The Support Tool does recognize the phone, but I am unable to upgrade recovery. It goes all the way to downloading software, but the time elapsed stays at 00:00:13 (13 seconds). I do have the firmware installed on my computer though, and I am now able to access CWM. Help?

Search for G3 unbrick here in xda or google. There's a few threads about how to "unblock" the phone.
I've done it twice already because of tests on it...

This thread is supposed to also work on the G3. Thought it might help:http://forum.xda-developers.com/showthread.php?p=50775936

First remove your battery then insert battery dont power on mobile . holding the volume up, plug in a microUSB cable into your phone.
Make sure the USB side is already plugged into the computer
You should start to see "Download Mode" for a few seconds and then it will show "Firmware Update". You are now in Download Mode!
Open LG Flash Tool and Put your dll and tot files in and use Board DL (Very Important)
after u success
It should boot into MiniOS just hit ok. Push power button plus touch the screen where it says Normal boot+(power)
done

This is not working for me. it says waiting for connection, please help
i am frustrated !!!

Try unplugging and plugging back in and ensure you are on PORT41 for the device driver. After you do that and in Download Mode, then unplug and replug USB.
Also do not use USB 3 and try another port if you still have issues.

I have same issue in my LG G3 D850 I have apply your procedure Thanks It works ... first time the setup screen completes but when i powered off mobile and insert the sim and then powered on its again going to miniOs again i Normal boot+(power) but now boot looping auto ... what can i do now ???

For me who had the same issue, I just rebooted the device back into download mode and the LG flashtool resumed automatically. (I did not close or stop the process from the LG flashtool when I got this message).
Once the process resumed automatically, I still got download fail.
I can see whenever the device reboots, the modem disappears from within device manager after getting to the "Factory Reset 2" screen.
Any advice?
Update: I tried about 7 times to get it flashed. I ended up just restarting the phone in normal mode and strangely voila it works perfectly. Even though the software said the flash failed, it still worked. Thanks anyway!

I just got a LG harmony and as i soon turned it on it went to factory reset status and I tried to bypass but it keeps taking me to Factory reset, I also tried the download mode which took me to firmware update for hours it has still been at 0%. Taking forever

If I remember correctly (please check threads here, it's been a long time since I've used this device, so memories are fading), download mode is activated when you press Volume Up (or both of volume buttons) and insert USB cable. I know that E98x has some strange button sequences, like rebooting to recovery is a two step operation (Volume Up + Power until navbar blinks, then power button twice, that's the only way mine wanted to boot into recovery), so please check around.
As far as USB connection issues, don't use USB3+ ports and if you're on Windows 8.1+ and later, run with Administrator privileges. I never experienced that one (used LGFlashTools from inside VirtualBox running Win XP for all my needs, I'm not a Windows user), so can't really help much but forums are full with explanations how.

Thank you very much...now the phone is back to initial state. This what i've done:
1. Download LG Flash tool from http://lgflashtool.com/
2. Download LG USB Drivers from http://lgflashtool.com/
3. Install LG flash tool and LG USB Drivers
4. Plug usb cable to phone
5. Hold volume buttons and then plug the usb cable to PC (i use win 10)
6. Voila, the Download Mode icon is showed up
7. Run LG Flash Tool (Administrator privilege) & follow the instruction (i use e988 v20c stock firmware)
8. Phone back to normal (only if you use the correct stock firmware)
A very big thanks to ShadySquirrel
Hopefully this thread can also be used as reference for anyone who has the same issue as i had

LG G7 bricked

Hello. I tried to install Android Pie on my LG G7 ThinQ and it failed. When turning on the phone it's showing only one thing (attachment). Tried to enter to download mode, but it's going back to this screen from attachment. Tried LG Up but it's not recognizing device. Can somebody help me? I don't want to give it back on warranty or to support.

hello, the same thing happened to me, I wanted to flash the 9.0 with lgup and when I reached 98 I launched error, my lg g7 now only enters fastboot mode and with the cmd I can execute commands like fastboot boot and fastboot devices, but lg up not recognize. Someone to help please ??

Here is picture

You can try with usb connected, press and hold volume up before restart to download mode to LGUP flash again (try with 8.0 or fresh download fw).

Same with me when cross-flash from HK region to EU region, always to flashboot or recovery mode.
With usb cable connected with PC (your G7 always in fastboot mode) force restart by press and hold volume down + power until screen turn off, release two button and fast press and hold volume up before LG 7 logo. My G7 boot into download mode.

hi
- While holding Volume Up key connect your phone to PC using USB Cable (Don’t leave volume key while connecting)
- Release the Volume UP key as soon as the phone goes into Download Mode.

Guys, I called you in one message as it seems we all had experienced the same drastic issue with the phone got bricked on the update process. We all probably used LGUP and on the update somewhere on the %'age progress (in mine it was 91%) the process stopped so we needed to force reboot and after that we got only fastboot menu.
Once trying to enter download mode, upon connecting to USB, the download mode title frame blinks for a split/second and it goes all way into fastboot only, correct?
Having said that - I believe it is vital not only to update how you resolved (or still resolving) the issue but how it happened we stepped in that deep sh!t overall...
On my particular case - I had bought the phone with branded oreo software, what I wanted was to (a) force-upgrade to Pie (as the brand operator is still very late with the Pie update) and (b) unbrand to open or brand Orange as I wanted the VoLTE and VoWiFi working. I used the LGUP 1.14 and tried uppercut but it did not work in my case (probably because of antivirus software something was permanently blocking) so I found the common_dll file which resolved the issue and the progress started. However, as mentioned - at 91% it stopped and phone died. I moved it to LGE service, they replaced the mainboard as it is under warranty. I suspect I used some sort of invalid DLL file, probably that caused the process crashed.
As a postmortem - I regret that in panic I force-rebooted the phone, it was certain the system won't start and now I realize it was also a high risk it will be bricked but you know... just tried to resolve instantly. I wonder what would happen if I would not reboot but leave the phone in download mode (still hold on 91% but still alive) and in that state would connect the phone back into LG Bridge software or LGEtool - possibly it would be recognized by the firmware auto-flasher inspected or fixed and it would reboot itself properly into download to resurrect...who knows.
I am looking forward your status guys - where are you with the fix and actually how did you go into that trouble - so what flash method you used ? You know, to avoid that scenario in future...

I investigated the problem of why it stopped at 98% and it is because of the issue of the ddl file, before any flash by lg up it is better to prevent and replace the common ddl file, which I did not do. just in case, I still have the phone in fastboot mode, I have not been able to find a solution yet.

So.. Ive actually managed to get outta fastboot and into quallcom9008 mode.. (Deliberately..) But.. Cant do **** ib that mode just yet.. Software not available.
Now i read about resetting while in thar mode via test points. Will let ya know if there comes anything from that..
(Btw... To get into 9008 mode.. Hold power and vol down while in that gawd aweful fastboot tutorial menu.. And tap the vol up button fast and repeatedly.. If it resets and you have a blank screen.. Ya there..!! If it just resets to.. Well. Fastboot.. Ya didnt rap fast enough.. Do it again.
To exit 9008 mode.. Just hold power and vol down till bootlogo comes up..
It aint much. But maybe some1 more clever can use that info and get us outta that gawd damn menu.. plz..

If you are stuck in fastboot loop see this post:

I hope you fixed your issue but if anyone needs it here: go into edl mode and flash laf_a and laf_b. these are download mode files. I will attach these files later today
