I was having some 4G connection drops with my phone, so I tried to do a Factory Reset using a KDZ file, I was on version 20t Android 6.0 Official Rom, with LG UP I tried to flash the 20t KDZ file, but I was not getting past 9%, so tried to downgrade to Lollipop 10C firmware, it seemed that it was going well, but got to 21% during the System flash and and error occurred and the flashing process stopped, so removed the battery, plugged back in and now the phone only boots to Download mode, tried installing all the LG UP files from here and the LGUP_8994_DLL_Ver_0_0_3_23.msi file as well, to no success, also downloaded the 20c ROM and got to 23% but failed again, last resort tried the old LG Flash Tool 2014, but again did not even start to flash the ROM, so I'm stuck now =( and not sure what more to do guys, any help/ideas would be awesome =)
[FIXED]
Simple solution, connection to LG Bridge did it, detected the phone even in download mode, downloaded the proper software and that was it, flashed without any issue =) Me Happy =)

Hello. This is my first time actually visiting the Optimus One forum although I have had my phone for maybe 2 months. I was not going to root my phone, in case I need warranty, so I was using the stock rom, although it was a little slow.
So I thought MAYBE there is an update on LG website, so I went on there, and found out that I can update by connecting to the computer. So I did download all the files they required (at least I think I did), and I followed the instruction, and started updating. Here comes the first problem encountered: While the phone was n Emergency mode, during the updating was in process, it said Phone and PC has problem communicating or something like that. And there was a restart button. It said disconnect the phone, and remove battery and connect again, and then press restart. So I did. Then now after that the LG software update tool doesn't recognize the phone. It said connect it and press OK or something. I think this is the point where I bricked my phone. A NON rooted phone. So I don't even have a custom recovery to flash anything! I hate LG right now. They are so stupid. I don't know what happened..
I tried the method here:
http://androidforums.com/optimus-one-support-troubleshooting/237642-bricked-lg-optimus-one-help.html
But I couldn't download the right KDZ firmware for my phone, that is available in the link in that link above. I'm in Canada and my phone is from Koodo and the model name is P500H.
So I got a random KDZ file that's for P500 from internet, but the in the KDZ_FW_UPD emulator, that's in the link above, it says my phone is NOT detected! I reconnect the phone and restarted the software so many times. I think they want me to connect the phone while it's Turned ON, and press the "Connect to USB" button. I'm not sure though.
***PLEASE*** Help me! I really need to unbrick this..
Sorry for the long post. And Thank you!

Thank you SO much for your reply. I was searching for HOURS, and Finally found out how to make the KDZ update tool recognize my device. A LOT of people can't get it to work, but I saw someone in this post http://forum.xda-developers.com/showthread.php?t=1015332&page=4
that you need to remove sim card and battery. So I did, and restarted the update, and YES! It worked! I was on Foryo, but I got Gingerbread Rom from
this forum http://mobilesyrup.com/forum/showthread.php?t=21446&page=2
And I'm actually on GB now!
OMG, I have so much homework, but have been doing this for the WHOLE day! Wow..
Thank you so much for your help anyway!

Chapter 1: The Foolishness of the User
Hi, I have the korean version of the optimus one(KU3700). It was on gingerbread(2.3.4) stock. I was trying to root it by downgrading it. I entered "adb reboot recovery" and I'm stuck. I tried to reflash it by going to emergency mode with the button combinations using the KDZ updater with this
"csmg. lgmobile. com:9002/swdata/WEBSW/LGKU3700/AKTFBK/KU370040_00/KU370040_00.kdz"
and it worked without any errors but when it when it came up it was still on recovery mode. Is there any way I can change the phone mode to the regular mode
Chapter 2: Journey to Salvation
For anyone who has this korean optimus one, after days of searching, I've found a web site that gave me hints to solve the problem. I just needed a different kdz file and I got it here:
h t t p://sirospace.tistory.com/category/Android%E2%97%86
popped it in google translate because I'm Filipino and can't read korean.
Downloaded the froyo kdz and flashed. I hope this can help other people stupid enough to play with their phones by typing random commands without knowing what it does, like me, LOL...so happy, now it's time to root
Chapter 3: False Hope
OK so I have successfully unbricked and rooted my KU3700, now The problem I have is installing a custom recovery on this phone, none of the images I try work.
Recovery images I have tried are as follows:
recovery-RA-GNM-thunderg-1.1.0.img
recovery-RA-GNM-thunderg-2.2.1.img
recovery-RA-GNM-thunderg-3.0.6.img
Every time it finishes and reboots, it gets stuck at the LG logo.
Chapter 4: Wisdom Within
Found the problem. The images above are for the P500.Even if the KU3700 hardware is similar to the P500, flashing firmwares made for the other model will result in errors. The same holds true for custom recoveries.
Chapter 5: The Plea to the Gods
I've contacted drellisdee and submitted the files needed for custom recovery creation for the KU3700.
Just waiting for the flash image now. Thank you everyone
Chapter 6: The Forgotten
It seems drellisdee is busy right now. I'm a windows user and knows nothing about programing. So if anybody can help I'm sure the KU3700 community would be greatful. I've attached the files I think are needed to make a custom recovery.
Chapter 7: Quest for the Custom Recovery
I got tired of waiting. So as a windows user with no experience in programming, I did a lot of copying and pasting, I managed to port clockwork mod using virtualbox following this website:
h t t p://www.koushikdutta.com/2010/10/porting-clockwork-recovery-to-new.html
So I have got a bootable and flashable custom recovery but nothing works yet. I still need to configure it according to the device.
I have uploaded the image and the build files. Please help me configure it and tell me what's wrong. I really don't know that I'm doing
PS: you can try flashing the custom recovery by doing "fastboot flash recovery /Path to/recovery.img and you can go to recovery by using android terminal and type "boot recovery". It will boot, but that's that LOL. Take out the battery to boot to normal mode.
Chapter 8: The Holy Grail
LOL, I found the answer again. I was so frustrated that I kept squishing the phone in recovery and found out that it was just a button configuration problem. A bit of research and I found out that I can toggle it by pressing volume up and volume down at the same time. WOOHOO!!! Custom Recovery at last
Chapter 9: Invasion of the ROMS
And here at last, the user is retired. But the adventure is far from over. It is foretold that the creation of the Custom Recovery will begin a new era. The key to open the gate has been found. So our hero will await the invasion of the ROMS<background music...> END

Thank you for the reply but as I said, I can flash fine without errors it's getting back to regular mode I have a problem with. Rebooting and reflashing does not take me out of the recovery screen(it's just a opened box with an orange arrow and the android logo).

This is just a shot in the dark because i didn't understand what you did entirely : have you used the combination to actually recover the stock rom after you flashed with KDZ ? (Home+VolDown+Power)
Yes already did. The computer can see the phone whenever I connect it except that I can't access adb. I may have to take this back to the store

Are you sure you flashed the right rom for your phone? There's an application that downloads the required rom for your phone according to your IMEI/SN, but i don't know if it works with the korean version.
Yes it's the KDZ file, unfortunately it's the only KDZ file out there for ku3700. Shouldn't have settled for this korean version
why you wanna downgrade the latest version?
Dude I have the same Korean edition as you.
Actually why you wanna downgrade the latest version.?
My phone had 2.2.2 and I did upgrade it into 2.3.4 I did it officially and I can tell you How to re-install 2.3.4 if you want.

Thanks for the reply. I wanted to downgrade it to root it. And now I'm rooted. My only problem now is installing a custom recovery. I've already tried several custom recoveries:
recovery-RA-GNM-thunderg-1.1.0.img
recovery-RA-GNM-thunderg-2.2.1.img
recovery-RA-GNM-thunderg-3.0.6.img
but I get stuck at the LG logo when it reboots. I think it's because it's for the p500. So if you have a custom recovery for the ku3700 please help
I dont get it ,p504,p505,p506 are versions of p500??? And why some of our roms work on those phones?? So by logic this stock work on p500???

this method worked for my working KU3700 when I'm using my 1st KU3700 I also was struck as you and finely I realized there are No custom roms for Optimus one Korean edition (KU3700/SU370) and I had to connect my phone to an Octopus box (lg softwere box) via software box installed the official firmware. if this method not working you have to connect to a software box.
connect to the internet your PC and 1st install Driver and 2nd install the LG update tool. after installation connect your phone to computer and wait a five seconds for comport installation. after install your phone Run LG Update application.
it is connect to the server automatically indicating red line and after search for latest firmware.
if you can Update your phone it is shows Update butten.

Thank you all for the quick answers, but I already have a rooted ku3700. All I need now is a working custom recovery. If someone has the same phone, please tell me which image is compatible
you can appear the emergency mood with android logo.
it means you have an Empty phone. your Os was been erased. You have to connect your phone to Octopus software box and box server has you original Os for your IMEI. this is the only solution. if you will able to solve this problem without a Software box please inform me. we can open a New Thread for Korean edition.
(ku3700/su370)
I already got out of the emergency mode without an octobus box. It's really simple, you just need to use a different kdz file. The hard part was looking for the kdz file. I have 3 kdz files. KU370017(froyo), KU370033(gingerbread-rootable), KU370040(latest one from LG, gingerbread-unable to root). Just flash with the KDZ updater. I'm on the second firmware because I can't root the latest firmware. To root it, I used super one click(latest version, use zerg rush option). Now I'm just waiting for a custom recovery from drellisdee so I can use custom roms. When I get it, I'll ask him if I can post it so we all can have uber phones LOL

If you have flashed a working clockworkmod you can enter into clockworkmod via ROMManager (search in google play aka market). In ROMManager you have "reboot to recovery" option in case you want to go to recovery to flash something. Also you can try to flash from ROMManager a custom recovery (5.0.2.0 for oldBB or 5.0.2.7 for newBB), try to choose to phone model LGP500 oldBB, try and test if it's working. Wish you luck.
Thanks but I already have a working recovery. I just need some ROM makers now

Have you tried CM7.2? if your phone is very similar with Optimus One i doubt it isn't compatible with your phone.
If your phone use 2.6.35.10 or 2.6.35.14 kernel you can give a shot to try CM7.2 on your phone, but before try this make a backup first.
Check this thread Post Your CyanogenMod 7.2.0-RC1 Nightly Questions HERE!! for CM7 custom rom.
yep, it doesn't work. Is there a tutorial for building cyanogen for unsupported devices? All I can find are tutorials for supported devices. I've already got the source code from LG. The problem is just incorporating it in the cyanogen mod. I wish this phone had more users LOL
so I managed to root my device without bricking it
and now I needed the twrp recovery thing so I could install cm 10.2
now I followed some tut on youtube that told me to use flashify which I did and I then downloaded some old version of twrp with it
when I rebooted my device it said safe reboot error or something.. and now it does nothing (freaking out here)
it won't turn on even when I try to reboot into recovery when I put it in my pc it shows like 10 storage devices that I need to format
pleasse help me (I had this phone for less than a week now))))))

First step: Don't panic!
Second step: Tell us which version of the G2 you have (carrier) and which update you had on before things went south, and also which version of TWRP you have.
Third step: Please explain what you mean by it not turning on but plugging it into the PC shows odd things.
Does that mean you CAN still get into recovery? Can you get to download mode? But either way, just stay calm. I just helped my buddy with the ATT version fix his phone from a similar issue a couple of days ago and I have also played with the Sprint version quite a bit and am familiar with LGs in general. Lemme know these things and I can help get you back on the right track.
Can you get into recovery mode?
If you can, try the factory reset and reboot your device.
Does your phone connect to adb?
If so i guess you could flash a fresh rom from there.
Correct me if i'm wrong, i am a new user with slight experience.
Same Thing Happened to Me
I'm freaking out a bit as well. I tried the Flashify method of installing TWRP and got the error message followed by a blank unresponsive phone. Got there via a "Phone Tech Kid" video explaining how to install TWRP. Plugging it into my computer results in being able to open a "drive" with one folder titled "image". The image file that I flashed is 2.6.3.2-g2vzw obtained via a link from this video:
Has anyone come up with a solution?

Probably would be best to start your own thread. However, what update were you on? I'm hoping that you do have the Verizon version of the G2? What error is on the screen? But generally speaking, you should be able to boot to the software update mode and re-install the stock OS with the kdz file, for most G2 things. I haven't worked on a VZW one though, only Sprint and T-Mobile ones and they're all a bit different.
At this point i'm desperate. I flashed my lg g2 with it's original firmware and rooted my phone. Saw the OTA download on notification but didn't touch to install as it said. However, I did restart my phone and I got stuck in a bootloop. Did a factory reset and use twrp adb terminal to write this command: dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota. However, I get an error saying memory full. So, I tried download mode and tried to reflash my phone that way, however it gets to 4% and then I get hit with a wparam error. I been searching the forums and trying everything with no luck. Anyone in the metro area NYC that can help? I will pay you a 100 bucks if you can get this thing working for me again.
Were you using a custom recovery before bootloop?
I followed this guide and was successful in flashing the phone to it's original state http://forum.xda-developers.com/showthread.php?t=2432476 Then I continued to follow the the tut and root the phone, which I was also successful. I continued the follow the tut and flashed twrp and noticed I had the OTA notification. I thought nothing would happen because I didn't touch the notification to install it, however when I flashed and restarted phone I got the lg bootloop. I tried the adb commands that could be found here on xda but I get the error that states something about memory. I then tried to reflash the orginal firmware using the above tutorial but I end up getting a wparam error at 4%. At this point I don't know what to do, adb won't recognize my device so I can't go that route either.

It's time for you to contact customer service of your telecom provider.
In download mode it shows that my phone is rooted. Also, doing a reset takes you to the twrp recovery. Will tmobile be thorough enough to go through all these steps to try to help or will they just switch out the phone for me? I got it back in mid March.
Which phone variant do you have and what ROM did you try to flash?
Tmobile D801, didn't flash any rom. I just flashed the kdz file that was in the tut I linked above. Then I flashed twrp and restarted phone, then bootloop. Saw the OTA notification, however I didn't touch the button to install.

Can you mount a usb stick in twrp via otg? If so you could flash a Rom from there.
if you can enter download mode try the TOT method and make sure you take all the OTA's before rooting it again.
So after reading and searching I finally found out the problem and was able to reflash the firmware. It was so silly but I wanted to thank xda user kimitza for mentioning this in the guide posted in this hread http://forum.xda-developers.com/showthread.php?t=2498102
All I had to do was use the usb port in the back of my pc rather than the front one. I know it's silly but up until now I have been doing everything from the front usb port but never in download mode. I was able to flash the firmware originally from the front usb the only difference was that I was always in the android os and then it would restart my phone then put me in download mode.
In any case, i'm glad I got my phone working and wanted to thank everyone who took the time to send messages offering help as well as the people here in the thread.

Lucky for us, you don't read. He managed to restore it to working condition.
I know this thread has been posted millions of times, nothing at all works for me
Ok so I rooted my phone yesterday and thought I'd try Cyanogen Mod. After following every step in the Wiki, it had me install AutoRec and reboot, and now I'm stuck at:
Fastboot mode started
udc_start()
- reset -
- portchange -
fastboot: processing commands
When trying LF Flash Tool, it says phone is disconnected, I can't go into download mode, or do anything like that, only fastboot mode. When trying to go into download mode it works for a second before going into fastboot again. Hardware factory reset does not work either.
I've tried MANY threads/videos/etc (B2CApPSetup; LG United; some Fastboot tool; LG FlashTool; SO many more) and none of the programs work. I really need my phone and I desperately need any help. I have ZERO clue where to go from here. I thought about just trying to install CM again through whatever means possible but I can't even seem to be able to reset the phone to stock.
If factory reset isn't taking you to the recovery, it sounds autorec didn't work? I don't know, I don't have a VS980, but in your position I'd make sure the LG driver package was installed, make sure Windows is actually using the fastboot driver when connected in the device manager (Win 8.1 here, I've always had to manually tell it what driver to use), then I'd fastboot flash a twrp img, which would hopefully allow factory reset to take me to recovery. If that works, you'll probably have to adb push a Rom over.
Hopefully someone with a little more insight can help you further / better.
It's not really bricked at all. You most probably downloaded AutoRec for an other variant, next time read more carefully.
You'll need to flash the stock aboot, boot and laf images back using fastboot.
I know you said fastboot doesn't work, but it has to work. Try updating your drivers, use a different PC or something. You can download said image files from here, BUT I'm not familiar with your variant, so I have no idea which version you should download, it would be the best to use the ones you've just overwritten with AutoRec; if they are on the linked server, good for you, if they aren't, you might better extract them yourself from the kdz.
I followed some link to tell me what kdz to get, its' called VS98026A_00.kdz. How do I go from here to just reset my phone completely?
This is pretty much my problem:
Reddit r/lgg2/comments/2b7tob/installed_autorec_and_stuck_at_the_boot/
I'm amazed I got this far. I really need all the little details I can get lol.
gyazo.com /56a5a1ff9b071f8505b883c753dcf6d9
Ok so I tried LGFlashTool once more after doing fastboot with LAF.img and says it can't find phone.
Sounds like you should update your LG drivers.
If you can't get download mode to work, flash these images the same way you flashed that laf.img one. I think you'll be able to boot to system just fine. I included a laf.img in the rar as well, you can skip that one I guess.

I flashed boot.img then restarted and it was stuck at LG icon. I restarted it and got it into firmware update and it seems to be frozen at 0%. Was I supposed to do aboot before fastboot reboot? Thank you so much for your help btw, I have no idea what I'm doing really.
Sounds like you put a different version of a bootstack your vs980. I've seen too many people screw their phones using autorec. If you can't get it fixed by doing a kdz restore and are still under warranty, call vzw and get a warranty replacement.
Then use my Freedom Tools made only for the VS980 to get a custom recovery on your phone to flash roms.
