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
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!

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...

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.
https://docs.google.com/file/d/0B-f4fsQKNhx4ZzE3Q1I4bEYza1k/edit?usp=docslist_api. Unzip folder. Turn usb debugging on on your device connect phone to computer go unzipped folder. Double click on lg root script in folder. Let it do its thing it will reboot your device . When your phone boot the command window will say can't find your phone id number or something like that and will ask you to go into download mode. Power phone off when completely off hold volume up and connect the usb Cord to phone. Then let the script do its thing when prompt to click n to reboot . when device reboot on you should be rooted. Hope this help someone the other way i couldn't figure out how to do my pc.

yups, works perfectly on AT&T H950 10d.
Please install LG Drivers first and the tool does everything automatically.
I successfully rooted my H830 2 days ago, but today I followed this thread trying to get some adoptive storage, http://forum.xda-developers.com/lg-g5/how-to/enable-adoptable-storage-t3368207 and it bricked my phone. So be careful to modify your build.prop file.
Update: the boot problem was caused by build.prop's permission, I did the change in PC and copied it back to Android, but I forgot changing the permission to 744.
Anyway, it also gave me an opportunity to try some method to unbrick my phone.
1. First I tried LGUP and stock TOT file, I got an "unknown model“ error when opening LGUP. It worked fine 2 days ago when flashing the modified TOT file. And there's no driver issue, in device manager I can see "LGE AndroidNet USB Serial Port (COM3)". I guess LGUP need to recognize the phone when it's up for the first time.
2. I also tried LG flash 2.1.0.6, this one totally not work on H830, it failed to load the TOT file.
So please share the information with me if you know how to work around the LGUP "unknown model" error or any other way to unbrick LG G5 H830. Thanks in advance.
Are you able to get into TWRP? If so, you could try editing your build.prop through the terminal using vi. Maybe revert the changes you made?

1. First I tried LGUP and stock TOT file, I got an "unknown model“ error when opening LGUP. It worked fine 2 days ago when flashing the modified TOT file. And there's no driver issue, in device manager I can see "LGE AndroidNet USB Serial Port (COM3)". I guess LGUP need to recognize the phone when it's up for the first time.
2. I also tried LG flash 2.1.0.6, this one totally not work on H830, it failed to load the TOT file.
So please share the information with me if you know how to work around the LGUP "unknown model" error or any other way to unbrick LG G5 H830. Thanks in advance.

If you simply changed a line in your build.prop i doubt you are hard bricked. As the other user suggested boot into recovery (vol down + power when you see the lg logo let go of power and quickly press and holding power again. then select yes) once in twrp plug your phone into comp and adb push a stock build prop. you will have to ask someone to pull theres for you.

Are you able to get into TWRP? If so, you could try editing your build.prop through the terminal using vi. Maybe revert the changes you made?

Yes, you both are right. The problem was caused by build.prop's file permission. I did the change in PC, and copied back to android, but I forgot changing the permission to 744. That's why I cannot boot.
I just boot into TWRP and correct the permission, it all works now.
Thanks both for the help.

I did not try it myself since I was able to solve the problem by changing the file permission.
Where can one find the stock buildprop file for the Tmobile G5?
Hello All, I think I hard bricked my phone.
I cant seem to connect to my phone with LGUP directly with all USB and DLL's installed. I had to use Uppercut
I tried to use Uppercut+LGUP and downgrade my OS to the previous version, however it always fails at 11%.
Failing which, My phone seems to be a brick.
When I power on my phone the only thing I see is...
LG Logo. then immediately, Firmware Update
If I plug in the power to charge, the phone shows the same thing.
LG Logo. then immediately, Firmware Update
If I trry to boot into recovery (vol down + power when you see the lg logo let go of power and quickly press and holding power again.)
Same thing...
LG Logo. then immediately, Firmware Update
Any suggestions?
Thanks.

SInce you're already in download mode, I would just use LG Uppercut and load the 20A rom. Let me know if you have any other issues.

Hi! Could you please link me to a working 20A ROM please?
Have you done any aftermarket ROMs yet? Kind of want to try cynogen/lineage but still need to unlock first.

put this .dll in the common folder, let's see if it happened by chance. https://mega.nz/#!qV9WzQSQ!Z0Zkpm-m3LJ01tLthzfE9puNmYlbsOoZR5N-f2VS_mw extract and rename LGUP_common.dll

Does lgup recognize it? What drivers do you have installed? Let's see if I can help.
If you remove the battery and put it back, does the phone turn on?

Thanks for the reply. From all my problem descriptions, and with picture of the phone still turning on to download mode...
I installed,
LGUP_Install_Ver_1_14_3
LGMobileDriver_WHQL_Ver_4.4.2
LGBridge_Setup
UPPERCUT_1.0.0.0
...and despite changing to different usb c, the phone is not any visible to pc nor lgup or device manager.
The main problem i'm facing now are the errors on download mode.

if it works, install the latest version of android 8 for your model with lgup not with uppercut, run the lgup exe.

I already placed the common dll for f800k prior to flashing oreo which is the same file and oreo kdz i used to update from nougat.
still, pc isn't making any sound of connection of phone been connected
Also the LGflashtool from the second link i already tried earlier. COM41 is not recognised since the phone doesnt communicate with the ports, so not visible to Device manager

If you remove the battery and put it back, is the phone still the same? The cell phone cannot be turned on, so it is a brick. I will go looking for possible solutions, and consider the possibility of using another PC or try to install updates for your PC if it is not already installed.
When i remove and reinsert and then using the vol- & power button combo the phone is still entering download mode with the Unknown / E / L / RO error
Maybe i'll try another pc and give back reply soonest Thanks
I think I have a similar problem that I solved. I wanted to try to flash the root on 9 android, but it didn’t work, the smartphone stopped showing in download mode and in the device manager, but it was detected in fastboot mode. I'm not sure that I showed the same errors, since the stripes on the screen did not allow me to examine the text. Flash recovery https://androidfilehost.com/?fid=11410932744536982447 through fastboot mode, and in recovery-> format data, flash firmware in zip format from 995 https://forum.xda-developers.com/v20/development/vs995-verizon-lg-v20-stock-oreo-rooted-t3845669. After that, the smartphone was detected in download mode and I reflashed it. (I have f800l)
I guess i'm quiet unlucky now in my own case because i am not rooted and no fastboot stuff.
I'm only able to get to Factory Reset menu using the VOL- and POWER BUTTON and releasing the power button and press again POWER BUTTON once lg logo appears.
Also I'm able to get to a SELECT MENU that contains MA-USB(WIFI) DL, POWER OFF, PHONE INFO, BACK by tapping the VOL- or POWER BUTTON like 6 to 7 times repeatedly while in download mode.
Neither of those helping the situation
yet the value of B kept on decreasing now on B59. May that is for the battery? Unknown BATTERY59
