If you did something like install custom recovery on your lg optimus one and failed, you would get a black screen saying..
fastboot mode started
udc_start()
If this happens...
Relax.. Your phone is not bricked.. There are many ways to fix it... This method of unbricking should be done as a last resort because it erases all your data...
Charge your phone before proceeding even if the backlight is always on while charging..
Things required:
Kdz updater:
Stock ROM:
Required- 1. USB cable 2. Windows PC with administrator account 3. LG united mobile drivers
1. First Go to My Computer> Right Click & go To properties> Thern Go To Device Manager & disable all LGE modems under modems from Windows device manager in the Control Panel.
2. Make sure you have LG united mobile drivers installed & you have restarted Computer once after installation of drivers.
3. No the trick is here…. press and hold both the back (return) button and the volume up button and simultaneously connect the USB cable.
The phone should light up and say Emergency mode!! in a green background.. If it goes to Emergency mode, it can be fixed... If it doesn't I'm sorry, search for an other forum or give it to the LG service center...
4. Now decompress the KDZ file you downloaded using WinZip, WinRar etc., install msxml.msi from the uncompressed directory and runKDZ_FW_UPD.exe (With administrator rights by right clicking and selecting run as administrator).
In the dialog box, select Type : 3GQCT and PhoneMode: DIAG, select the kdz file and flash the stock ROM... It would take about 15 minutes.. If the kdz updater crashes, change compatibility mode or restart the computer and phone or do something till it works (Retry retry retry)...
For most of you it would probably say PHONE WAS NOT FOUND!.... If so, then follow all the steps said above, again retry for endless times or restart the computer or check if any modem drivers are active or try it in an another computer...

We had the same problem. It bricked my phone and sadly it was out of warranty. I had to pay to have it JTAGged to function again.

What. do you not read? people on this thread are telling the OP to not use KDZ. plus he can't even get into emergency mode. so this won't work ? USE LGDMP! DON'T CONFUSE NEWBIES.
AND STOP PASTING THE SAME GUIDE THAT YOU COPIED FROM SOMEWHERE ELSE

Thanks a lot for the reply.
I tried but nothing happening..its not detecting as usb to change port to 41.
Is there any other way?? Also for flashing when i insert battery and press volume up and then connect it starts and shows LG logo and goes blank.

It is not showing in PORT in device manager when connected pressing volume + button

Does the phone go to download mode ("S/W upgrade mode ) ?? By insert the battery while you hold vol+ ??
You will see two arrows like the sync symbol in your phone screen . And then the phone will still connected with the PC .
Your problem is easy to fix . Just try to enter download mode . And every thing will be fine .
Good Luck

You hardbricked your phone if it doesn't go into download mode.
But no panic there is always a solution;
http://forum.xda-developers.com/showthread.php?t=1942836
Follow the guide above. (and I mean every step , however small they may seem)
ICS roms are now pre-rooted so you don't have to root.
Flash Xbsall's Ported custom ics (The one in the guide.)
Then install wkpark's recovery img. (Found here ; http://forum.xda-developers.com/showthread.php?t=1978543)
Boot into recovery.
Install Darkroom ICS Int. (It's the best in my opinion) or whatever rom you wish.
They are all pre-rooted.
If you can't i'll guide you through it.
Hope i Helped.
Cheers!

Thanks a lot for the help and i really appreciate your willingness to take me out of this trouble, Thanks again

Everything worked fine till step 9..But still not showing anything in Ports

Make sure the drivers are correctly installed. Especially omap4430...
Start the script that has been referred to in the guide.
Shut down the phone , remove the battery , plug usb cable and when you see "waiting for 5 seconds" plug in the battery. That should work.
Keep me posted.

That may mean you have a bad cable.
But if you restored it , it's probably sometimes bad or you changed it or you used the front panel which is a hub (divides bandwidth , slows flashing process) and it's bad for ya.
Since my real name is turkish and hard to spell i'll give one better ;
Call me John.
If you must know my real name is "Dogukan".
And yes i can help you with that although it's relatively easy now that you got a hold of it.

Thanks a lot Dogukan..
Are you into android development? Am a real noob in this and you helped me coming out of really difficult situation.
Now i want to root my phone and everytime its showing 'error no device find'

I'm not into android development... my skills lie in networking so there is not much i can do for android.
But those are common knowledge...
I bricked my phone several times to learn those.
You don't need to root. Follow wkpark's recovery installation and flash a custom rom (Darkroom int is great)

Sorry,I can't able to understand.

How to flash?
Can anyone lead me to flash a ICS?

No bro keep the cable as it is just download ics and then the drivers in the flashing thread any other drivers won't work .so uninstall current drivers then install the drivers in the thread...after that download LG flash tool and crack it then take out the battery and simcard memory ..and hold volume up and connect the cable then keep holding the volume up and count 3 seconds and put the battery in u should see s/w on your device in Korean release the volume up..this is called download mode now go to device manager and change the port to com41 then disconnect the device and open LG flash tool and choose only the bin file and download the DLL update file for your device and select as well and hit OK. Then change the LG flash tool port settings ( just watch the pictures in the flashing tutorial) after that hit the arrow button and u should see a ready sign ..then just put you phone in download mode and it will start flashing automatically it will stop at 80% -85% that's OK then the device will boot ice then just flash the base and ( fls) that works for your country

Fisrt Welcome to our forum ,, I hope you will see what you want .
you are new , you must understand many things before that .
1- this tool you are using is to solve problems or update phones .
But "LG Optimus 3D" did not has an official ICS rom so the developer "xbsall" port it from "su760" it's the korean version of our phones.
2- This program will put the system in your phone any way and it will work with it . BUT WITH OUT a signal .
3- To get signal you must the baseband that is work with your country.
4- your phone will enter "S/W Upgrade mode" some called it "download mode" or "emergency mode" ... in this mode the phone will connect with the PC and then you can copy the system into it by lg flash tool .
5- when your phone in "S/W Upgrade mode" your PC can't recognize it so you must install drivers .
6- after your phone enter the s/w mode and the PC detect it . And lg flash tool is ready . Then you can flash your new rom ICS.
Any question ,, we are waiting for it ..
About the dtails do what "alphatia" said . No need to repeat
At first you will see it hard because it is too messy .
But after you do it you will see it too easy

Help needed

hi have been trying to update to 4.0 via flash tool but ive tried everything and cannot get it to work......ive been trying for 3 days and ive pretty much had enough of trying on my own so i though id would ask for help.
ok firstly i am on gb 2.3 im running custom cm7 no probs but i wana take the next step 4.0 so....i have all lg flash tool etc and fast load etc all nessacary files needed but for some reason my phone wont connet and flash its doing my head in. i have it into download mode, battery out etc but after that nothing i cannot progress further its like the program wont connect/register the phone.
im running win7 i even looked into other post and thought this maybe the problem but i have already installed these when gone into download mode as said here If you plug your Phone on PC without battery, OMAP4430 device appeared for seconds and then disappeared in your Windows Device Manager
(check arsen4oo photo guide in post #3)
On windows 7 sometimes OMAP4430 flashes too fast so you cant install driver.
There is a a windows feature that will help you install the driver easier.
To view devices that were once installed but are no longer attached to the computer, open a Command Prompt window using the Run As Administrator option and enter the command:
SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
Then, from the same command prompt, type devmgmt.msc to open Device Manager. Choose View, Show Hidden Devices. The new instance of Device Manager will show “ghosted” entries for devices that were once present. This technique is especially useful for fixing problems caused by leftover drivers after replacing a network card or video card—you can easily delete the ghosted device or update the OMAP4430 driver.e
i just dont know what im doing wrong
cheers in advance

HI,
Please uninstall all LG drivers, and start again. If you are using WIN7, run it with WINXP SP3 compatibility mode.
Getting the Software upgrade screen is tricky, the timing needs ti be just right for the screen to stay, else it blinks and the OMAPP difficulty starts.
You need to listed to the connect disconnect sounds carefully.
Its not difficult, just that the timing needs to be right for the battery to be inserted.
all the best

Make sure all the drivers from the guide are installed. (including omap driver)
Load the DLL and the rom to lg flashtool.
Listen to the port with LG flashtool's port settings. (One is enough , The icon with a printer cable that's the port settings)
Take the battery out but be ready to plug it back in.
connect the usb cable.
Hold volume up
You're gonna hear sounds from windows in this order ;
1.Connected
2. Disconnected
3. Connected (Again , when you hear this plug the battery back in)
If you did it right then you're now in download mode.
Go to the device manager , find the LG device (I don't remember the name , but there is only one so you'll see it.) and go to properties , advanced and port settings.
Change the port to com41.
Flashtool should take over and start.
For extra guidance , see xbsall's thread ;
http://forum.xda-developers.com/showthread.php?t=1942836

To enter download mode .
Your phone in your hands without anything :-
1- Pull out battery .
2- hold vol+ and keep holding .
3- Connect your phone and you are still holding....
4- Now the phone is connected and you are holding vol+ . Insert battery and keep holding for about 3 seconds . Now the phone in download mode (there are some korean words on the screen) .
That's all

Because you're flashing the baseband before you flash the ROM. Change the sequence , ROM first then baseband. (Just remove the baseband you added on the flash tool ".fls file" then add it again it's gonna be flashed after the ROM )

Help me....

There is an emergency mode you can try as long as you have the software on your computer to flash factory settings on to your phone.
Toemergency mode:
1) Take out the battery
2) Have a usb cable already connected to the computer.
3) Hold the power button + volume up + back button AND then connect the usb while holding those buttons
Yellow screen will appear with the words emergency mode in the middle.
At this point, do some forum searching, find some kind of stock image file and LG program to flash stock system on to the phone.
**I DONT OWN THIS DEVICE** but i had a few cases and this should work for you too

Your device is hard-bricked. Your only bet in LG. Go to LG and tell them you turned it off, and now it doesn't start up

That thing happened to my phone a year ago. You can't do nothing at home. Go to a service.
