Are you sure you cannot get into download mode? Hole power til you see the LG logo twice, then release so it powes off completely... Then hold only Volume up and plug the phone into your computer while holding it.

What did you do or think you did to cause this? I would be easier to help if we knew what you were doing when this happened.

I had the same problem. Spent nearly 10 hours trying to figure it all out but never made any progress. I sent it to LG though and they are working on fixing it up right now.

i got an update after i installed it it didnt boot to system , went to recovery and after i restart it this happened . .
try plugging it in and use the LG software...I never done it myself but if you search i think there is a way you can fix it using LG software.

I am not sure if you this will help 100% but what I did was installed the recovery in my phone then I updated my phone. Which made my phone go in recovery and if I restarted it gets stuck in recovery. I wasn't able to get in download mode as well.
If you can get in "recovery" then you can use this fix
to get in recovery hold the vol- and power button until your phone vibrate and you are in recovery.
then execute these commands through adb shell
http://forum.xda-developers.com/showthread.php?t=2451696
Edit--- after executing the commands flash the stock rom--- using LG flashing kit. Search the xda and you will be able to find a thread that details how to do it. yes you will be able to get in download mode, i got there in 2 tries.

What kind of update caused this? You mentioned you got an update and then it was stuck dead.
Rooted/Custom Rom?
I was about to root my device and came to look at some instructions, this thread scared me...

Sorry, can't read the link, but by recovery, you mean TWRP, right?
So basically, after rooting we can still do an OTA update, and it's still safe, right? But once we installed TWRP, we should not do any kind of OTA updates?
For TWRP, is this method good enough:
http://www.youtube.com/watch?v=nTJI9ThY0mk
To Root, I will use this method:
http://www.youtube.com/watch?v=Y45SXPRb31o#t=149
Sorry if I am steering topic off-course but I just wanted to make sure others don't do the same mistakes and end up in same situation.
Your suggestion of not doing OTA update is really valuable, so I wanted to build on that.

The easiest and the way that really worked for me was to root it using "Vroot" http://www.mgyun.com/
but you should check which phone you have and which OTA version you have. As far as I know 11g and 11c for korean variant can only have cwm i am not sure if that is true for other phones as well. But be sure to check it. TWRP only works for 10x versions (where x is any alphabets) still dig deeper, I might be wrong.
But you should never update your phone after recovery.
and backup your IMEI number ... the thread i posted earlier try using google translate and download the apk to backup your IMEI by Hoang.

Hi everyone, i'm french so excuse me for any mistakes
I have a tablet, I passed under ICS due to a file update.zip downloaded from the site of Acer. Then I root the tablet and then I tried to install a ROM or I'v been warned that I had to first unblock the bootloader, so I follow a tutorial that seems to work but when I try to start my Tablet with the "POWER" button and the "Volume -" button it displays a robot with a red exclamation mark( !) . . . But she work normally when i don't try to do recovery mode....
I do not know what to do. . .
Thank you in advance !

Well then rip.
I got "td4310 1080p video mode dsi txd " panel and the above-mentioned recovery work's fine. You check ur panel Using any app like dev check or hardware info app and do a bit of searching for the recovery.
