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)

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
Good Luck

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 )
Edit : I can help via team viewer if you want.

[GUIDE] [P720/725/720H] Resurrection Guide (Let´s get those brick´s fixed)

Hello Guys, i have to show you, how you can recover your LG P720/725 and 720H. It´s very simple. Since i have my LG P720 i have reflashed my phone so often by this step´s
there give´s 3 methodes to bring your Smarthphone back to orginal
First what do you need.
First off all you need the KDZ from your Phone and the *.cp and *.ap also the binarys
----------- S/W MODE --------------
Plugged your Batterie out of the Phone. Wait 3 seconds.
Bring it back and insert your USB Cable to the Phone. Then Hold the Volume+ Button for 6 seconds. Your S/W Mode will start.
Now Connect your Phone to the PC, maybe you must install the Driver. (There are in the LG Flash Tool Package included)
If you didn´t flashed your Phone and it´s bricked automaticly , you can use the First Methode
--------First Methode ------
Connect Your Phone via USB to the PC and bring your Phone in the S/W Mode.
Start your LGMobile Support Tool and start the Emergency Mode, it will download the KDZ and flash it new to the Phone.
You have flashed a wrong Bin or KDZ to your Phone? Or Your Bootloader is bricked, also Bootloop ? Use this Methode
---------- Second Methode-----------------
You need the "LG Flash Tool Package" and the full working "LPG720 DLL" you can get the FlashPack here p92x.acidhazardrom.com/ccount/click.php?id=15 . This Includes all relevant Drivers, install it.
Here in the Post you find the LG Flash Tool 1.2 without Drivers
and the DLL are from here http://forum.xda-developers.com/attachment.php?attachmentid=1937519&stc=1&d=1367761284
The SmartFlash Tool http://hotfile.com/dl/143853325/ed430ad/SFT.rar.html Password [email protected]
--If You have a Behavior Blocker on your PC, disable it ---
Install all Drivers from the LG FlashPack.
Bring your Phone to the S/W Mode, install the Drivers.
So after you installed it, go to your Device Manager on the PC and change the Comport under connections > LG Modem ..... to COM41. Disconnect your Phone.
Install the FlashTool, then Start the LGFlashTool.exe from the LG Flash Tool 1.2. Then Select Manual Mode, choose the DLL and add your AP.bin and CP.fls. Press OK. Goto the COMConnector Button and Choose the Port 1. OK. Click on the Arrowbutton , the Program will be ready. Connect your Phone in S/W Mode now to the PC. It start´s automaticly and flash´s your device new.
After your Phone is ready, check your Mobile Network, if its false,"No conenction" you have to reflash the Baseband.
Use the Smartflash Tool, bring your Phone Back to S/W, start Smartflash and connect your phone. Goto the Register Rom Copy D/L under CP Bin use the *.fls binary. Click the Button "Start" now the Smartflash flash´s the Baseband new.
Now Your Phone is NEW.
---------------------------------------------------------------
My Smartphone is Permantently Bricked, bootloop, flashtool can´t flash anything(but i have used it correctly), Kernel Error or anything else
----------- The Third Methode-------------
So Guys, this is complicated for noobs.
You need the OAMP TOOL, download it here http://forum.xda-developers.com/attachment.php?attachmentid=1937574&stc=1&d=1367763391
Now unplug your Batterie from the Phone, and connect it via USB to the PC. Now he will install the Driver, make it manual and choose the Driver from the folder usb_drv_windows, includes in the Package your downloaded.
So now if you have installed the Driver, start the "start_fastboot.bat". Choose your Phone and press the Button on your keyboard, the Tool will bring your Device to the Fastboot mode, if its write to start the mode "Pls wait 5 secondes " is now in the Screen read. Plug your batterie back to your phone.
then choose "install orginal bootloader" and follow the Steps. After you have to all, bring it back to the S/W Mode and follow Second Methode.
------------------------My S/W Mode is Gone-------------------
Follow Third Methode, but hold your vol up button permanetly , this will bring your Phone to the S/W Mode.
----------------------- Nothing goes, i think my Device is Bricked permantenly, fastboot can find any partitions or any thing else--------------------------
After i had this Problem, i fixxed it. So start Omap, choose your device. Hold permanently your Vol up button, plugg the Cable to usb and insert the Batterie. Omap brings your phone back to S/W.
Now flash your Stock Image with FlashTool, maybe 3 Times.
It works for me
----------- Other Mode KDZ_FW_UPD ---------------
i have forgot to tell you this mode. For this you need the KDZ File.
Download http://forum.xda-developers.com/attachment.php?attachmentid=1949514&stc=1&d=1368135582
Its the same methode with the LG Mobile Support Tool, but offline.
Bring your Phone to S/W Mode and connect it to the PC.
First you have to edit your hosts file. Open it and insert this 127.0.0.1 csmg.lgmobile.com
then start kdz server, start windows enabler. See at the Tryicon click on it and make it ON.
Then open UpTestEX_mod2_marwin
On the rigth side, click on select kdz file. Choose your KDZ.
On the Bottom start "normal web upgrade test"
Then Upgrade Start.
The Mobile Support Tool opens and flashs the KDZ
This was a short Guide to bring your Phone back. If You have questions so ask pls =). Btw sry for my bad English, but i hope you can understand it
Added CWM for P720 maybe P920

Hi,
How do I get the binary files?
Also, the SFT.rar file is asking for a password.
If I have the KDZ, .bin and .fls files, i can use this method to upgrade to later version of software as well ( I am on V10C on P725, I can use this method to upgrade to V10F as well)
please help.
schubeir

ok if you read the Guide you find
The SmartFlash Tool http://hotfile.com/dl/143853325/ed430ad/SFT.rar.html Password [email protected] <<<<<< Passwort
the Binary files are from the KDZ, you musst extract them with LG Extract Tool
you can Use SFT or LG Faslhtool to flash you binarys.
If You have only the KDZ Use KDZ_UP......

Good Job !!!

Dear MasterTobi, hello!
I am trying all these methods, but I can't unbrick my phone! I can enter 2 different screens for S/W Upgrade, one by normal mode, another by OMAP boot mode, bu tin anyone my phone goes live... Do I have to select the port 41 in LG Modem in Device Manager, and after this, port 1 in the LG Flahs Tool? Is it correct? When I try to do this, I got the message "Downlaod Fail" each 20 seconds in the port 1 field at the LG Flash Tool.
I tried the methods in this post and another ones, but anyone works for me. Do you have any idea?
Thank you very much!

Connect Your Phone via USB to the PC and bring your Phone in the S/W Mode.
Start your LGMobile Support Tool and start the Emergency Mode, it will download the KDZ and flash it new to the Phone.
You have flashed a wrong Bin or KDZ to your Phone? Or Your Bootloader is bricked, also Bootloop ? Use this Methode
---------- Second Methode-----------------
You need the "LG Flash Tool Package" and the full working "LPG720 DLL" you can get the FlashPack here p92x.acidhazardrom.com/ccount/click.php?id=15 . This Includes all relevant Drivers, install it.
and the DLL are from here http://forum.xda-developers.com/attachment.php?attachmentid=1937519&stc=1&d=1367761284
The SmartFlash Tool http://hotfile.com/dl/143853325/ed430ad/SFT.rar.html Password [email protected]
--If You have a Behavior Blocker on your PC, disable it ---
Install all Drivers from the LG FlashPack.
Bring your Phone to the S/W Mode, install the Drivers.
So after you installed it, go to your Device Manager on the PC and change the Comport under connections > LG Modem ..... to COM41. Disconnect your Phone.
Install the FlashTool, then Start the LGFlashTool.exe from the LG Flash Tool 1.2. Then Select Manual Mode, choose the DLL and add your AP.bin and CP.fls. Press OK. Goto the COMConnector Button and Choose the Port 1. OK. Click on the Arrowbutton , the Program will be ready. Connect your Phone in S/W Mode now to the PC. It start´s automaticly and flash´s your device new.
After your Phone is ready, check your Mobile Network, if its false,"No conenction" you have to reflash the Baseband.
Use the Smartflash Tool, bring your Phone Back to S/W, start Smartflash and connect your phone. Goto the Register Rom Copy D/L under CP Bin use the *.fls binary. Click the Button "Start" now the Smartflash flash´s the Baseband new.
Now Your Phone is NEW.
---------------------------------------------------------------
My Smartphone is Permantently Bricked, bootloop, flashtool can´t flash anything(but i have used it correctly), Kernel Error or anything else
----------- The Third Methode-------------
So Guys, this is complicated for noobs.
You need the OAMP TOOL, download it here http://forum.xda-developers.com/attachment.php?attachmentid=1937574&stc=1&d=1367763391
Now unplug your Batterie from the Phone, and connect it via USB to the PC. Now he will install the Driver, make it manual and choose the Driver from the folder usb_drv_windows, includes in the Package your downloaded.
So now if you have installed the Driver, start the "start_fastboot.bat" follow the Steps. BUT we choose press now the the Button 1 on your keyboard, the Tool will bring your Device to the Fastboot mode, if its write to start the mode "Pls wait 5 secondes " is now in the Screen read. Plug your batterie back to your phone.
then choose "install orginal bootloader" and follow the Steps. After you have to all, bring it back to the S/W Mode and follow Second Methode.
------------------------My S/W Mode is Gone-------------------
Follow Third Methode, but hold your vol up button permanetly , this will bring your Phone to the S/W Mode.
----------------------- Nothing goes, i think my Device is Bricked permantenly, fastboot can find any partitions or any thing else--------------------------
After i had this Problem, i fixxed it. So start Omap, choose your device. Hold permanently your Vol up button, plugg the Cable to usb and insert the Batterie. Omap brings your phone back to S/W.
Now flash your Stock Image with FlashTool, maybe 3 Times.
It works for me
----------- Other Mode KDZ_FW_UPD ---------------
i have forgot to tell you this mode. For this you need the KDZ File.
Download http://forum.xda-developers.com/attachment.php?attachmentid=1949514&stc=1&d=1368135582
Its the same methode with the LG Mobile Support Tool, but offline.
Bring your Phone to S/W Mode and connect it to the PC.
First you have to edit your hosts file. Open it and insert this 127.0.0.1 csmg.lgmobile.com
then start kdz server, start windows enabler. See at the Tryicon click on it and make it ON.
Then open UpTestEX_mod2_marwin
On the rigth side, click on select kdz file. Choose your KDZ.
On the Bottom start "normal web upgrade test"
Then Upgrade Start.
The Mobile Support Tool opens and flashs the KDZ
This was a short Guide to bring your Phone back. If You have questions so ask pls =). Btw sry for my bad English, but i hope you can understand it

Dear MasterTobi, hello!
I am trying all these methods, but I can't unbrick my phone! I can enter 2 different screens for S/W Upgrade, one by normal mode, another by OMAP boot mode, bu tin anyone my phone goes live... Do I have to select the port 41 in LG Modem in Device Manager, and after this, port 1 in the LG Flahs Tool? Is it correct? When I try to do this, I got the message "Downlaod Fail" each 20 seconds in the port 1 field at the LG Flash Tool.
I tried the methods in this post and another ones, but anyone works for me. Do you have any idea?
Thank you very much!

Sorry, but if I use your DLl, I got the message "Model Name is different! Chel phone or DLL!".
Also, I tried the smartflash tool, selecting the ap and cp. At the ending, appears a mesage "Magic number doesn't concide".
And finally, I tried the "Normal web upgrade test". This one looked as my phone would return to life, but not...
In any of methods I could turn on the phone. I don't know what I can do know. I am very, very afraid...

This guide is for P720, right? not Optimus 3D.
@wellington, which phone do you have?
Karim's guide is not for 3D Max, right???

My guide is similar to the Resurrection guide which supports 3D MAX, the difference is that I've added some different steps and a slightly different method.

My phone is a 3D MAX, a P725.
Tx!

Ok then, good luck!

Never mind.
Sent from my LG-P720 using xda premium

oh guys...............
so you have a magic number ........ strange, there is only the error if you have a wrong version
you have to download the LGP720AT-00-V10e-EUR-XXX-JUL-17-2012+0_AP this is for the P720/P725 alias 3D MAX

Success!
Hey people! I got success! After many days trying, I unbricked my phone! I will tell you what I did.
- My phone is a P725. I don’t know exactly where is it from. This information (P725) was very important for me in the unbricking process.
- I used the LG Flash Tool 1.3.77.21 (http://forum.xda-developers.com/attachment.php?attachmentid=984864&d=1333650043).
- Now, the two cheats that helped me to unbrick my phone:
1st: I didn’t use the .dll from the first page of this post, and I didn’t use the .dll, .bin and .fls extracted from the KDZ gotten from the IMEI of the phone. They didn’t work for me. I googled for these files for P725AT, which was the model that LG Flash Tool was telling me that is my phone. I found the following files:
http://freakshare.com/files/e6xssy95/BIN_LGP725AT-00-V10b-ARB-XXX-MAY-08-2012-0.zip.html
http://uploaded.net/file/v6orqts2
2nd: At the flashing process, there is a pause at 80% telling that the phone will reset. In some cases, the reset really occurs, but in my case, the reset didn’t occur. A lot of errors appeared (see the image), but no problem. I just turned on my phone, and BINGO! It was working again.
It’s important to tell that I had to put my phone in download mode using the OMAP TOOL, that can be found in the first page of this post (http://forum.xda-developers.com/attachment.php?attachmentid=1937574&stc=1&d=1367763391). Don’t forget to change the LG USB COM Port to 41.
That is my history! I hope that this help someone. I would like to thank everybody who wrote about the brick of this phone (MasterTobi, Karim Kahale, Eklovya Dutta [I'm not certain of how to link for them, sorry!] and anybody else), I believe that is one of the worsts bricks in smartphones…
Good luck for all!
EDIT:
I forgot to tell: all the process was made in a Windows 8 64 bit. It gave me some difficults to install all the drivers, but it is possible, Google it and found how to.

[Q] Help me.. My Lg optimus one p500.. BRICKED ???

On instalation with kdz file show me KDz Error and i ll removed a battery in emergency mode....And now my phone won't turn on..
Help me....
hard bricked my LG Optimus One when i remove a battery after kdz error..
my phone can't Connect on PC i have instaled USb drivers properly....After removed a battery in kdz error on emergency mode phone won't turn

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.
