The steps are okay (phone connected) but when it starts the update, it says communication problem between the phone and PC.

yes i got the same problem! Anyone with an idea?

A question:
What's you meaning for "emergency mode"? It's to put phone in original Android Recovery mode (push vol down+power)
It is the same thing?

Phone will not boot past recovery. Please help, major panic!!

Oh dear.....I hope I haven't destroyed my O3D....
I was attempting to install the V10D update, so used the backup I took right after rooting and installing ROM Manager to restore the phone to its status before installing the performance pack. If I tried installing the update OTA before this I just got an invalid package error.
So the restore went well and it rebooted fine. So I ran the update again, and it downloaded and appeared to install, but when the phone rebooted it just booted straight into the recovery. I tried to get it to reboot again, but again it just booted back into recovery.
Ok, nothing to worry about I thought, I just ran the restore again with the same restore point as before....but after it finished it's still booting back up into the recovery!!! No matter what I do the phone just seems to keep booting into the recovery menu. I've tried booting into emergency mode by powering the phone off, then holding the UP Volume key and holding power, but it doesn't seem to work.
Can anyone help? Please?
Lil update -
When powering off the phone and then connecting it to the USB cable, it automatically boots into recovery mode without me even touching the power button. At this point the LG Mobile Update detects the phone and advises me that there's an update available. I try to apply this, but after entering the SN and IMEI, it just gives me a message "Updating is not possible any longer due to a fatal error while the LG Mobile Phone Software Update". I get the same error if I use the recovery Phone option. This always happens at the download stage, so is it possible that it's just failing to download the update from LG rather than actually do anything with the phone?
Please don't tell me I've ruined my brand new phone!!

Unfortunatly, you've managed to do the same as I have... leave the phone for e a few days and wait for a rom that you can install via clockwork recovery, you'll have your phone up and running again. Dont do as I did and wipe the recovery from the phone, it will result in a total brick (or at least a brick till LG releaase a full rom update (could be months yet...).

Oh man, I'm panicking so much that I might have ruined the phone now.....

I'm not sure what I'm looking for there, I've looked through that thread but it doesn't seem relevant to the problem I'm having.

I have the same problem, if you put it into emergency mode you can update to 10d but then its even worse then you are stuck in the firmware update screen
tomorrow I leave on holiday and was planning for nice 3d pictures and movies but I am screwed...

Don't panic, I managed to totally brick my phone today and LG told me to send it back for DOA but I managed to recover it in the end.
My phone wouldn't show anything on the screen, it remained black so I can say your position sounds much better than mine.
What you will need:
USB Drivers - Download from here (Check note)
LG Mobile Support Tool (LGMST) - Download from here
Before you start: Disconnect the phone from the computer and totally remove the battery.
So here we go:
!!!REMOVE ALL THE LG USB DRIVERS FROM THE SYSTEM BEFORE YOU CONTINUE!!! Go to add remove programs, select the LG United entry and then uninstall it.
First install the USB Driver from the link above and wait until it has finished with the setup.
Then run the LGMST. When it starts and it says "Disconnected." then put the battery back to the phone and connect the phone to the computer.
Press ONLY the Power button and wait until something happens. If you see that the phones boots and the LGMST starts it by itself then wait till it stops with all the information gathering stuff.
Then regardless of what the program says of you having an update or not, DON'T START THAT UPDATE!
Click on alt on the keyboard and the from the menus at the top select Customer and then emergency(the last option).
Type in the phones IMEI (located at the box of the phone or on a sticker under the battery) without dashes, just numbers.
Finally click on Check and follow the instructions on the screen.
You should be ready as new after 10-15 minutes with the standard V10B firmware and you should not even lose data.
Tell me if that helped so if it didn't we can still fix it I'm sure
Note: I'm aware that 3.3.0 is the latest USB driver that it ships with the phone but for some reason I had only success to flash the phone using the older 3.2.1

That does not work for our problem, just a blank screen is better than stuck in firmware update mode :s

I'm afraid that didn't work (I think I'm gonna cry soon)
When I go to the Customer Support option, the last option isn't called Emergency it's called "Recovery Phone" and seems to launch exactly the same thing as it does if I click the big "Start Updating" button. There is no option named Emergency at all. Does that mean my phone isn't/wont/can't boot into Emergency mode?
I don't even hold down the power button for my phone to switch on, the second I insert the battery it boots into Clockwork Recovery. If I power off the phone and connect the USB, I don't get the battery charging animation or anything, the screen just remains completely blank. Then if I press the power button (alone or with anything else) it just boots to Clockwork recovery.
The LG Mobile Support Tool seems to detect the phone in this state, but as I said, when it tries to do the download, I just get an error saying "Updating is not possible any longer due to a fatal error while the LG Mobile Phone Software Update". The version of the Mobile Support Tool that it's installing is 1.5.1.8 after downloading from your provided link, just incase you need to know that. It seems the tool automatically updates itself on every launch.
Someone also seems to have posted the actual ROM in this thread, http://forum.xda-developers.com/showthread.php?t=1155874 would installing this perhaps assist? Is it even possible to install this when my phone wont boot up past the recovery manager? If it is possible can someone perhaps advise me how?

Unfortunately the phone wont boot into Emergency mode. The clockwork Recovery mod seems to have taken over all of the boot options. If I hold the volume up key and press the power button, nothing happens. If I hold the volume down key and the power button, it boots to clockwork recovery. If I just press power, boots to clockwork recovery.
Is there any way to strip off Clockwork recovery and restore the original/stock recovery onto the phone? Or even just remove Clockwork recovery so that it just hangs on the LG boot screen? (See reasoning for this below)
I can still select the USB mount option in Clockwork recovery and the PC still picks it up as a storage device and I can browse around.
The phone is only 7 days old, so I'm almost tempted to just delete the internal memory so that clockwork doesn't show up, then take the phone back to the store and say it wont boot up and try to get it replaced.
Or what would happen if I renamed the clockworkmod folder on the phone's hard drive?
(Just another note, I don't have an external SD card in the phone, just the internal memory)

How else can I put it into Recovery Mode? How can I tell if I've done it right?
I managed to hold the up volume key and hold down the power button, and the LG Mobile Update detected the phone whilst the screen was blank. I thought that meant I was in recovery mode?
I should point out that the LG Logo wasn't flashing up however. I only ever see the LG Logo before it boots into Clockwork RecoveryMod

I also got that fatal error thing when i bricked my phone. For me the phone would start flashing but it got stuck at 17% and then an error followed saying that there was a communication problem between the phone and the pc. My solution was to switch from my desktop computer to my laptop and the procedure ran smoothly after.
You said that the phone powers up directly after you connect it to the pc and while having the support tool running?
You can try to shut it down so it shows a black screen as you said and then try to boot into emergency mode with the vol.up+power button.
The windows sounds might help you on that. you can listen from the computer when the phone connects/powers up or not.
EDIT: Just read your post, if the phone remains black is a good thing.

if your update fails or goes into clockwork recovery etc you will need LG mobile update on your pc and install the lg p920 drivers
turn your phone off take the battery out leave it for 10 sec, connect battery and usb cable hold power and volume up hold it for 10 sec let go then do it again for 10 sec
now run LG mobile update click customer support > recover type your imei let it update once finished power up phone now you will get a screen on the phone that says updating let it update

Well I'm not sure what I did differently. Not sure if I wasn't pressing the button hard enough or my finger was slipping off, or if I've just somehow tricked the phone, but the LG Phone Update from the Phone Recovery option is now running.
I've been doing the same thing I was doing before (or at least thought I was doing) and I'm not sure what I did differently....but....fingers crossed..... the download will finish in 40 minutes (on a crappy connection at the moment) so I'll be able to see what happens then....
UPDATE -
Progress, though not quite yet success.
The LG Mobile Support tool downloaded the software and applied the update succesfully, though my phone didn't automatically restart. I pressed the power button however and it loaded up and not into Clockwork Recovery Mod. It's not however sitting on an "Updating Firmware" screen and the progress bar doesn't seem to be filling at all.
How long does this part of the process normally take?
Does the phone need to be connected to USB for this part of the process? The LG Mobile Support Tool says the phone is disconnected so I'm guessing there's no active data connection between the PC and phone, just power.
Does this normally take a while? Or should I perhaps try the recovery again?

This is only supposed to happen when you apply the OTA update. Try to reapply the stock firmware in emergency mode. After the program applies the firmware, it should boot up the phone by itself in android and give you a success or finish message on the computer.

Is applying the Stock Firmware not what I did with the LG Mobile Support Tool when it downloaded that huge 300MB+ file?
I have contacted the customer services for Carphone Warehouse, and the guy advised that if the phone seemed to have developed a fault and wouldn't start, then since it's within 28 days of purcahse I can get a like for like replacement. Might have to go ahead and do that this evening.

Flash KDZ or use LG's recovery to go back to normal. Boot it up on download mode for this.
This is what happens when you start flashing crap from 2X.
Probably since partitions are different, you've just formatted what you shouldn't have.

tnk everybody but it don't go in download mode! or maybe i wrong something....how should i try to go in download mode? with key combination it don go! please help

Try this:
1. Remove battery
2. Press volume up
3. While it is pressed, insert the usb cable
Should enter download mode I think.
If it doesn't, try the same thing but with volume down.
Afterwards, you can let go of the key, and go to LG mobile tools and on the menu click recovery. It'll ask for your IMEI, put it there and press ok. Wait for the process to finish.

but...KDZ is a us odin is for samsung? this is the first lg i have...maybe the last too

I try but after i inpout emai and product code, the download never start and a error messege appear

Try to flash a KDZ then.

how to flash a KDZ? what sw do I need?

I've try to flash a kdz but the problem is the same than before. the pc don't see the phone. I've try without battery pushing vol up and plug usb but it begin to feel the phone andg give error message sound continuosly like a loop. if i look the hardware in PC proprity it appear snd disappear with the sound tha i told before. it is like if I plug the phone 1 time for second...the pc reveak and reject it...I'm in a **** situation

Did you install the drivers?

yes of course..as I wrote on first message I've had allready root the phone with oneclick when everything happened...so the pc was allready pared with the phone...I really don't know what to do! that's a bad day for me

Connect usb cable, the telephone start automatically.
Press and hold power button to shutdown the telephone (ca 5 seconds)
Press Power button and volume up (hold the key for 10 seconds).
You can hear the usb sound from your operating system.
Repress power and volume up for another 10 sec.
You can hear usb sound, don't remove finger from two buttons, waiting another sound.
Now you can use lg software to try to restore the original firmware.
The problem for my telephone is the "upgrading firmware" page don't start... any time I power up the telephone I see the upgrading firmware page but the progress bar don't move.
I hope you have more lucky

I have the stock v10c ROM on a 'Rogers' LG Optimus 3D.
I had been using the Google+ Android client and pushed the power button to put the phone tosleep (with the G+ screen still being displayed). About 15 mins later I pulled the phone out of my pocket and it was dark, but the touch countrols were all lit up.
I know that usually isn't good news.
I pulled the battery and tried to re-boot. It gets to the Rogers bitmap and then boot-loops, with a flash of the Rogers scren each time it restarts a cycle.
I did vol+down+Power and the it booted into a recovery (3e) menu that only offered me the chance to wipe all user data. Ok. I did that. The phone then presented a triangle logo and the green android and sat there.
After about 10 mins I pulled the battery again and did the Vol+down+3D button+Power boot to the REAL recovery menu.
I then did a factory reset. I have assumed the Home button is the enter button (BTW).
Again the triangle and the green android appear. They are still there 10 mins later.
Not sure what to do now...the phone won't boot and the factory reset won't fix it. But it isn't dead. I can still get to recovery, so in theory this is fixable. I just don't have time for it right now.
I was wondering if maybe the phone had updated OTA in my pocket and i didn't realise it and I may have messed up the process. But I have never seen a phone do an OTA update without first notifying the user and seeking confirmation...so I that probably isn't the case.
Very annoying.
I'm posting this here in case anyone else has the same experience.

[Q] Can only boot by plugging charger????

Hi
Can anyone help please? Also, are there anyone having similar issue.
Issue: Pressing the power button is not starting my device. In order to power on I have to connect charger (not usb with PC) and then press power button. What I have noticed is that once I switch off my phone it gets in to "emergency/recover mode". I came to this conclusion because after I switch the phone off, take battery out and put back in and then connect usb cable with my PC. I can see OMAP driver loads and also in the PC's Device Manager I am able to see LG CDMA.... under "ports".
It was not like this until i started several attempts to flash baseband.
Sequence of actions
Here is the sequence of actions I went through and end up having my phone at this stage
1. Followed the procedure (http://forum.xda-developers.com/showpost.php?p=17177547&postcount=2) step by step using LG flash tool. The application was constantly crashing (PC is running on XP pro). Before flashing baseband I flashed GB hence I lost radio.
2. To bring back my radio I had to reflash 2.2 following the same procedure (emergency recovery method) in the link given in baseband flashing.
3. After finishing the recovery flash I could not start my phone using power button. I started thinking that I bricked my phone. I left it for a day. Then I thought that the battery is fully drained and is the reason for not powering on. When I connected charger I started seeing LG logo and also the phone was started. I was more excited and happy that my phone was not bricked. After this point I need charger connected everytime when i want switch on my phone. so, I am scared to swtich off my phone unless I have charger handy to me.
4. I removed all the application (LG flashing related) including LG drivers I installed before. Now I reinstalled all the necessary app and drivers for baseband flashing. This time baseband flashing was done successfully (though at 22%). Then I flashed GB rom and everything works fine.
The only issue i have is, I can not switch on my phone without charger connected.
If anyone knows solution please help me.
Thanks in advance.

I used to have the same problem,
I think its a problem about boot,
when I use lg tools it always gives error, because phone wont boot without charger, so it cant continue upgrading
I try flasing original kdz file from lg flash tool, and use emergency rescue mode,
I dont know but it somehow repair the boot
you can fix permissions before you use lg tools.
what error do you have while using lg tool?
can you post the screen capture

After i uninstalled all the drivers (incl. LG tools) and reinstalled and I am not seeing any more error while using LG tools. I even flashed GB baseband twice but no use. The link you have given explains the same issue I have.

I think you have to install froyo version of baseband and firmware first,
then try

STUCK AT LG LOGO:
with factory reset!
1) Start LG Mobile update
2) Power off your phone without USB cable
3) Connect the USB cable and wait for the LG logo and the annimation battery
4) Pressing Vol.up + power 6-7 seconde wait for the LG logo and The screen turns off
5) Again pressing Vol.up + power 6-7 seconde and wait until the drivers are installed (LG Mobile update detects your phone and the screen is always off)
-If this is the first time the driver install redone the item 5).
6) Click on User/Support then emergency mode, insert your IMEI and click on check
7) Wait for download and upgrading (15/20 min)
