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:
http://forum.xda-developers.com/showpost.php?p=8651505&postcount=1
Stock ROM:
http://forum.xda-developers.com/showthread.php?t=865479
USB cable, Windows PC with administrator account,LG united mobile drivers(google for it if you don't find it in the "Add or remove programs" window in the control panel)..
First disable all LGE modems under modems from Windows device manager in the Control Panel..
Make sure you have LG united mobile drivers installed.. Or just google for it..
Then 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...
Now decompress the 7z file you downloaded using WinZip, WinRar etc., install msxml.msi from the uncompressed directory and run KDZ_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, but this time, shake the life out of your phone after connecting the USB till the lines "PHONE WAS NOT FOUND!" stops appearing... If it does appear again retry for endless times or restart the computer or check if any modem drivers are active or try it in an another computer...
From here on, follow any one choice:
Choice 1:
Note: There is a fat chance for this choice to not work and for you to go back to the very first line of this thread...
If you want your phone to have all the data before you bricked it, just disconnect the USB when the phone shows the charge screen as if you are charging the phone while it is switched off.. (This was discovered accidentally by me so try it at your own risk ) After disconnecting try to power on the normal way and it should work and the phone should be like it was never bricked.. If it doesn't boot, retry flashing from the start.. If it starts and all your data is restored root it, install titanium backup and backup all your apps and data and save the contents of sdcard\titaniumbackup to your pc.. Then copy all you want in your sdcard to your pc.. Then redo all the steps without disconnecting till the kdz flasher says FINISHED.. This is because if you disconnect the usb in the middle, only half the rom would be installed which is unstable.. After installing the full rom, root it, and install titanium backup and copy all the copied content back to sdcard\titaniumbackup and restore them using titanium backup.. That's it..
Choice 2:
If you do not want the data and if you need to do a risk-free unbrick, then flash with the kdz updater and wait till it says FINISHED.. That's it..
Now that you know how to unbrick, try installing what bricked your phone again but this time in the correct way... GOOD LUCK...
AND FINALLY.... ONE MORE STEP.... PRESS THE "THANK" BUTTON IF I HELPED YOU IN ANY WAY...

By (has administrator) I meant to run kdz with administrator user account rights..
And for your phone not found problem, did you uninstall everything that I listed? If so then you should shake the phone more vigorously from plugging your phone to usb till the phone is found, seriously. If it is still not found, review if you have followed my instructions without leaving a single one out and retry till you suceed... Best of luck... Any more help.. Ask me.

Ok if you can't run it as an administrator try skipping that step and try connecting your phone without admin till your is found.. Try SHAKING...
If it doesn't work.. Take your phone and equipment to your friends home which has admin rights...try till you suceed because it usually is a painfree process.. You can fix your phone if it goes to emergency mode... Dont worry.. feel free to ask for help...

I just picked up a used LG O3D P925 that has no connection to any network (well wifi works). When I tried to update using the LG mobile update tool. I had a no success detecting automatically so I clicked recovery and manually entered the IMEI and S/N. Soon I got a failure error. Prior to this I read a thread about OTA firmware updates but I have no button for OTA update.
I tried rooting using megatron (windows version) and installed the LG drivers but windows keeps detecting new hardware and wants me to install drivers. When I click run it just says "daemon started" and I wait for a couple of minutes and .... nothing. When I check the apns either none are listed or I get a message about "reorganizing internal processes. please try again later " ...
I contacted someone who had their phone replaced by carrier for same issue. Possibly the carrier has blocked the phone from network? ...O I hope not
.... Help !?
is it a stock rom goto play store dl get ril what does it say. sounds like bad based band
Post-:
Rom:
Baseband:
RIL:
GetRIL says "unknown RIL found" (gives me an md5sum)
for Baseband it says XMM6360
then there are 3 options to DL but since I don't have root I am unable to DL these updates ... says " no permission".
here is the info from about:
LG- P925g
Android Version 2.2.2
Baseband Version L6260_MODEM_SIC_01.1042.00
Kernal Version 2.6.35.7
Build number FRG83G
Software Version LGP925g-V10c-JUL-20-2011
ok I have succeeded getting root using Unlock Root. Now when I open getRIL and select a RIL to DL the "ok" button is "greyed out" or not available, just the cancel button. So after I cancel and select another RIL to DL & install I get the superuser permisson granted message followed by a message that says "The system partition needs to be writable.... and back to the greyed out ok and cancel choice.

I seem to get hung up on the step where you check the device manager for current active "COM" ports. When I connect the USB (holding vol up + power) I get OMAP4430 appearing for a second under ports and I get the "windows has detected new hardware" flashing on and of simultaneously. The phone doesn't seem to want to boot into download mode and it doesn't vibrate after 3 seconds.

On The Phone Goto Settings/Applications/Debugging/ Make sure ADB is ticked and then try flash it again try a diff usb port also make sure its not plugged into a usb hub. if it fails again i think the problem is with pc not the phone
Try connect device without battery and with holding vol up. Then after device is connected (wait 20 sec wile holding vol up) reinsert battery and start update.

if it keeps connecting and the disconneting try this. attach usb cable to PHONE only then take your battery out, then put battery back in and quickly press volume up button and then attach usb cable to PC. keep hold of volume up button all time dont let go and install all drivers omap, usb driver etc.
hope it helps
I have managed to make things worse ... :crying:
Now my phone is stuck on the AT&T boot screen. The only way I can power off is to remove the battery.Yes I tried flashing the v20P kdz after I thought I could do much worse.
I no longer have a problem getting my computer to recognize the drivers. I'm not sure if I flashed the v20C kdz without a problem or not. I thought I was able to root and things were ok except that I still had no network connectivity. I don't recall exactly what I tried next but I think I lost root somehow and some of the installed apps began misbehaving. I also noticed that superuser was not installed. I tried to root again but couldn't. I treid to flash a kdz again but again not very successfully. I also tried repairing the IMEI using this guide http://forum.xda-developers.com/showthread.php?t=1734330
I flashed the CP ? but didn't manage to restore the imei.
Now I when I power on I get the AT&T animation ... I tried to flash back to the 20C kdz without and luck. Now I have no idea where to go from here and would be grateful for some input.
try updating again but let the process fully complete http://forum.xda-developers.com/showthread.php?t=1244490
If you were stuck on the art boot screen after flashing v20p you should have don't a hard reset and wiped all data. I had the same issue when going from v10k to v20p. As far as the no signal goes I'm not sure but it could be a bad radio or it could have been stolen and deactivated by AT&t

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!

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.
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.

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.
