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
Hey all,
I have a CWM backup of my current rom and have backups of apps and data but am stuck at a bootloop.
As I have read countless articles, it seems my error is because I have a locked bootloader(not actually sure). Though, I only tried to flash
clockcycle's wiped v20d cwm backup file. It failed part way saying it couldn't write to /system.
Since then, I haven't been able to fully enter CWM. just see the red triangle with the droid guy on his back.
I have read Cmahendra's unbricking guide but it doesn't work as I have installed JB and even the tips to unplug, wait 10s and reopen the program to flash again it still won't work. Still stops at 15% saying error connecting to the phone.
There is a similar thread which had this exact problem which said to
use the online method to recover your phone since I had already installed JB. I edited the hosts file to remove the fake offline server and opened up the b2CAppsetup.exe, clicked on customer support,
entered my model LGP769BK and my S/N and it began to start the process and 'analyze' then crashed and said "updating is not possible any longer due to a fatal error while the LG mobile phone software Update"
I've tried to search this out myself and not waste any space but I'm at loss here. If anyone has any help, it would be much appreciated
as I don't have a phone while this is not working.
I've tried all the ways to to hard reset, master reset and still I get the droid guy on his back. I can get to S/w mode like all the other posts say to do but none of those fixes seem to work for me. Am I missing something?
Do I have any options here? I have kind of read that I should just unlock the bootloader but I don't think that applies in my case as I can't turn on my phone fully.
edit: for the online method(LG support tool), it basically cancels when it goes to the 'downloading' phase --> this is what I've seen as most of the answers but doesn't work
Upon further reading,
many seemed to need to replace their u-boot and x-loader
I did so and installed fastboot using Lelus' script here:
http://forum.xda-developers.com/showpost.php?p=41768774&postcount=1
I used option 6 which allowed me to flash the u-boot and x-loader from p760(works with my 769 and others as it says in the options) for JB
I'm not sure if I needed this as I don't have an unlocked bootloader.
I'm not sure of commands in fastboot but I ran
fastboot devices and it showed something
I also ran: fastboot flash recovery recovery.img
and I put one of my cwm backups in the "yours" folder
After I activate fastboot, it brings me to the C:\fastboot\yours folder
I assume this is for me to put my intended files in but I'm unsure if I should use my cwm backup or something else?
After it flashed the recovery img, I sent a fastboot reboot command
but it still went back to the droid lying down with a red triangle.
As some of you may see, I'm not too great with this but I feel like I'm close. Does anybody have an idea of what I should be doing?
should I flash an update.zip?
I don't know many commands but hopefully this gets me going in the right direction.
PLEASE HELP ME!!!!
I guess your cmw restore formatted your system but couldnt load the new system
the recovery you run with a locked bootloader uses a technique called 2nd init which i think is somewhere stored in the system partition. so when the recovery formatted the system, it lost itself too.
I've had a similar problem. the way out would be booting into the SW upgrade mode--switch off the device, remove the battery, remove the usb cable. press the volume up button and connect the phone to the computer. wait for a couple of seconds and then insert the battery.
you should be in the SW upgrade mode
now use the B2C client. if it gives an option to upgrade, use that otherwise, go to the customer support menu and press recovery phone
I have already done earlier. It may have gotten lost in my frenzy of information. I have put the phone into software mode, as you said, and it won't work either; There's no option to click upgrade because it's JB(V20D) and when I click recovery phone and enter my imei, LG mobile support tool(B2capp.exe) analyzes and then has a 'fatal error'
Since I flashed the new u-boot and x-loader my screens are all backwards/mirrored. Maybe the tool flashed an unlocked u-boot and x-loader if that's possible.
Is a recovery possible by fastboot?
I have a clean and full copy of my cwm recovery as well as apps and data backed up, I just need to get this phone in working order

If you fastboot flash the u-boot and x-loader from p769(ICS) it should go thru with the offline flash detailed in cmahendras guide.
http://forum.xda-developers.com/showthread.php?t=2085344
Use the KDZ_FW_UPD.zip from this thread
Or try this
Remove all of the stuff you have downloaded for this. Download the original B2C client from LG's site and use that

I have the updated kdz fw upd .zip from the unbrick and root thread as well as downloaded a new, official B2C client but they all still hang at the download part during phone recovery.
Tablechair, that did the trick.
Is this because the tool we use to flash for the offline method doesn't recognize the x and u-boot loaderse of JB?
After I installed the ICS boot loaders, my software upgrade mode wasn't mirrored anymore.
I did as tablechair and flashed the V20D.
Does anyone understand why this problem happened in the firstplace? Maybe I didn't get a full copy of clockcycle's backup cwm
or should I have not flashed his recovery in the first place since I didn't have an unlocked bootloader?
Again thank you for all your help and if anyone can provide answers to my other supplemental questions, that'd be great.
Off to root and probably unlock bootloader to be sure.
edit: I can't find the thanks button. but thank you very much tablechair. much appreciated. Hope this can help someone else
p.s. also big thanks to those who made the fastboot program for p769(Artas182x and sguerrini97). really an invaluable tool as I now know.

Things don't always go according to plan, maybe his Clockworkmod backup was made from the touch version and he didn't have artas182x second init recovery installed. So when the cwm failed the first time, did you try to restore your cwm backup?

Not yet. having problems flashing a kdz again. I've tried the 2 different software modes, as well as setting emerg and diag but still getting stuck at 15% again.
Do i have to replace my uboot and xloader with the ICS ones every time I want to use the offline flash method?
edit: yup, after replacing with ICS loaders again i'm able to flash using software upgrade. will update on whether I can restore cwm

I realized I misread your question. When I flashed before the incident, it failed to write to system and I didn't restore my other folder. I rebooted and it was all missed up. Anyway, now that I've got everything back and now with an unlocked bootloader, i was able to recover my old image. However, data isn't working so I have to find the radio to flash as I recall reading in other threads.
Can someone explain in laymen terms why this is? recap, i was on unlocked bl rooted jb and I flashed my old cwm backup when I was rooted but had a locked bl. My apps and messages were all there but the radio was different. I'd understand if I was going from ICS to JB but I was on JB both times. The only difference being a locked BL. It's got to be something about the Radio from p760 or V20B that didn't work on my earlier backup or something like that because the layout status bar is different with a "data" button and showing H instead of 4g(which are the same afaik).
Since, I restored to my backup from after my bootloader unlock and root so data is working showing 'H' with the different layout
Also, I had problems backing up and restoring until I noticed that it works better when I power off the phone and do the manual commands to enter recovery as opposed to using the app to send me to recovery(where I incurred /system backup errors).
My last question is which cwm recovery should I use? I currently have the one for a locked bootloader installed as per Artas182x's website. On that post he has a link for an unlocked bootloader recovery on the xda forums but that thread was updated to not working. Are there any disadvantages to me using a locked bootloader cwm recovery?
I don't think I have any option but to try it as I want to flash CM10.1 for p769. I also read that if your bootloader is unlocked, you can download the cwm from the googleplay. If this is true, can I just install over or should I uninstall the Artas182x locked bootloader one????
update: have to remove l9 recovery by deleting the appropriate system folders and then flash the appropriate .img through adb commands
Help.

Although I might be late, I have the same problem and the same phone and I really need help. I have a soft bricked phone lg optimus l9 and I had the same problems that you had exactly... Which is weird exept I don't have Clock Work Mod or anything ... If you get this I would really appreciate some help. Thanks
yup me too
I finally got software upgrade to work with my lg p769 that was security error cuz i still haven't unlocked the bootloader, if i knew what a good job lg and T-Mobile did in locking it i would have waited and got a g3 that my buddy rooted in like 5 min and unlocked the boot....
What worked for me is this LG FLASH TOOL 2014 THREAD ON XDA
http://forum.xda-developers.com/showthread.php?t=2797190
flashed both the 20H and 20D successfully i uninstalled everything lg in the control panel first though.
Hope this works for you cuz i was struggling on and off for a month to get this far lol
the 2014 tool ultimately worked for me too, once I fixed a couple things. I had rooted and forgotten to unlock, so it was at Security Error, and it would also disconnect at 15% .. in the 2014 tool, I had to install all the updates even though I'm in windows 7 or it would keep doing it. All good now.
I have been trying all these methods and I am still not able to get in the S/W upgrade mode. The only thing I am getting from the device is being able to put it fastboot mode (The inverted one). I really want to revive this phone
Thanks in advance for any help given

Hey, it's been ages since I have done any of this but IIRC, if you can get into fastbood mode u can still get into software mode,
- turn phone into fastboot mode
- open the software upgrader thing as you normally do
- maybe switch emerg to diag or something like that
- this part is where it's slightly different than the normal way(same program but u select a different option than the default 1st option on
I think if yoiu look through the tutorials it does mention an alternative method for getting into software mode
in one instance in my past, i had to reflash the ICS boot drivers so the software installer would recognize that
the flashing of the ICS boot drivers is done through fastboot. Should be a post in my history where I asked a question regarding this.
Sorry for the chaos but maybe this will help you get in the right direction since I don't know any of your phone history and what you've done etc
best of luck mate

Hey, I have been trying it with the fastboot but it keeps timing out and not allowing me to finish. One thing I should let you know is that, ever since I had put the device in fastboot, I am not able to get back the S/W upgrade mode. Dont know if that will help in seeing what my problem is or if you want me to explain everything from the beginning again, I am more than happy to.
Have you followed the steps that I linked to in the first 3 posts of this thread?
Follow the steps to flash the ICS bootloaders in fastboot and then you can do the fastboot trick for getting the software to recognize your device.
Right now your phone has the JB boot loader on it and is thus not recognized by the software.
recap:
step 1: flash the ICS bootloaders in fastboot (look at the linked thread in post 2)
step 2: use the software in emerg or diag mode but sitll follow the same steps as the tutorial. I think my earlier posts should explain precisely.
if you dont flash the ICS bootloaders, it won't be recognized by the KDZ installer
Updated 2/3/16 Master Download Link Added at Bottom of This Post For All Old and Current KDZ's
This method is confirmed working 100% for devices running 10b/11c/12b/23abc regardless of root/unlock state. While the .tot method is also working on Windows 7, users with Windows 8.1 are having difficulty using that method. Myself and @autoprime obtained a 10b KDZ file that has solved the issue for +10b updaters that couldn't flash back to 10b, so please send him some love for his help and for hosting the file on Team Codefire's servers for all to download. A big shout out to @quangnhut123 for creating the super sweet modified LG KDZ Flash Tool 2014 that makes KDZ flashing an absolute breeze!! He deserves some love as the previous KDZ flashing methods were anything but fun - especially on Windows 8. And another shout out to @deathsquad737 for initially testing the method for our device.
-Please this post and second post FULLY before asking questions!
-First remove any of the .tot flashing tools/programs that you may have already installed as they will conflict with the KDZ flashing tool.
-Download and install the latest LG drivers for your phone here (FYI I am linking the LG site directly instead of the file to ensure that you download the current up-to-date drivers): http://www.lg.com/us/support-mobile/lg-VS985-Metallic-Black
-Download the VS985 10b KDZ: Downloads Located Below
-Download the LG Flash Tool 2014 from this thread here: http://forum.xda-developers.com/showthread.php?t=2797190 and be sure to thank @quangnhut123 for his efforts. Also read that thread a bit so you understand how to fully use the tool exactly, but I will outline the process below.
-Extract the .zip folder to wherever you wish to keep it (desktop, downloads, etc).
-Copy the 10b KDZ file (or whatever KDZ your flashing) into the LG Flash Tool folder
-Power off your phone completely, hold volume up, plug in the usb cable, wait for any drivers to load, and you should then be in Download Mode
-Run LGFlashTool2014.exe (you may need to run as administer as its not an installed program, rather an executed one from wherever you saved the folder).
-You may need to install Visual C++ Runtime Library. If so, refer to the LG Flash Tool thread for more info on obtaining that.
-Select CDMA as your type
-Select Diag as your phone mode
-Select your KDZ file that you copied or pasted into the folder
-Choose the option of CSE Flash (this is a full wipe, you will lose your data). Do not choose Normal Flash when performing a downgrade, nothing good will come from doing that!! Another screen will open, just leave everything the way it is.
-Click the Start button and yet another window will appear showing a language selection screen. Just leave everything the way it is as Korean and hit OK. Don't worry, the tool is already set to flash in English.
-Wait until the Flash is done 100% and unplug/reboot... and that's it - now enjoy your corrected mistake and stop taking OTA's!!!
KDZ files rock, and are nice and easy to flash. No separate DLL files or changing ports either with the tool linked. If any other KDZ files become available in the future I will add them to this post along with any tool or flashing method changes. This thread will be solely kept for KDZ flashing for the VS985. I will also help as much as I can if you run into trouble, though I am not a Windows expert and actually only boot into it when I have to run programs like this....Linux MInt FTW!!

New download link to all KDZ files thanks to @roirraW "edor" ehT https://www.androidfilehost.com/?w=files&flid=35484
-For reference, here's @ins5736 thread for restoring using the .tot method: http://forum.xda-developers.com/verizon-lg-g3/general/restore-verizon-to-stock-t2827878 .
-Also there are reports of the tool deleting the KDZ you copied to the Flash Tool folder after the flash. I cannot confirm this, as it did not happen to me, but to be safe make sure you copy the file to the folder instead of pasting it so that you don't have to re-download the file for future use.
-Please note that the KDZ file we have is build # 10B.01, while the .tot file available is build # 10b.03. The only difference between the 2 files is that the .03 build is the actual released build that shipped with the phone, while the .01 kdz build was obviously a pre-released build. Its most likely some minor last minute changes/bloat added. We can't find any noticeable differences between the 2 builds.
-OTA's WILL FAIL USING THE 10b KDZ FILE WE HAVE due to a signing error with it being a pre-release. The purpose here is to downgrade, unlock, and flash whatever you want. This is NOT to return to an official stock state. You'll need to use the .tot file or the official LG Flash Tool that downloads the current build automatically in order to be in an official "stock" state. The 12b kdz is official and will allow OTA's
*Error Update* So with this leaked LP image, I've been playing with kdz'ing quite a bit and with a new Windows install I got to experience a few of the issues being reported by others that I have never seen, along with trying to troubleshoot some others. Did I manage to fix them easily you ask?? Hell yeah!
USB Disconnected Issue: This is a driver issue. Very easy fix, just download the latest Verizon drivers from the link I posted above and install them without phone plugged in. Power off phone, hold up, plug into usb and WAIT for download mode drivers to install (as stated several times in this thread). Click the balloon to watch the progress, this took about 10min on an i5/ssd machine - be patient. This is the predominant issue I think people are having. The drivers while in download mode are:
-USB Composite Device
-LGE Android phone or LGE AndroidNet for VZW USB Serial Port COM5 (this is the important one)
-CDC Serial or LGE AndroidNet for VZW USB Modem (this will fail if you are on a rom with certain VZW items removed - not a problem, its not needed)
-CDC ECM LGE AndroidNet for VZW NDIS Ethernet Adapter
If driver install fails, manually update them by pointing windows to the driver file you downloaded. I am not going any further here, use Google.
??????'s In The Field: easy, don't change region or language from Korean as stated in the OP. Leave it alone, it will flash in English I promise you. Result = all fields readable in English while running
Connection To Server Failed: Simple, ignore the window. Just drag it away, but don't close it. This is an offline hack originally indented to run online, deal with the window!
Progress Bar: The tool will initially analyze the phone, then when flashing starts, pay attention to the phone screen which will now say COM5. The blue progress bar on the phone is the important one. At around 80% on the tool screen, the phone will reboot. The flash is over and the bar will continue to progress into the 99% while rebooting - then the program will crash. You can disconnect now, you've been successful.
Thanks for the help and the new guide

I'm getting a message saying "Path is too long or file problem" when adding the kdz. Any ideas?

Sounds like your linking the file path instead of directly copying the file right into the folder. Also try checking the file md5 with this one for the 10b kdz file: d228ba692ef0c4704cba0b00fad8b8ce
Don't Forget To Remove Previous LG FlashTool
When I first tried the method I was receiving a message "Path is too long or file problem". So I read through the instructions again. I failed to remove the previous LG FlashTool I was using. Once I uninstalled that program, everything went through without a problem. Thanks annoyingduck!!
I keep getting this and I installed all drivers. Any ideas? Thanks

Some basics to check first:
-Were you in download mode before executing the program?
-When you initialized download mode, did you wait to allow the download mode drivers to load before hitting start?
-Were all steps followed?
-Check cable, and try another one (this is very often the cause)
-Change usb port
-Don't use a 3.0 port, use a 2.0
Thanks for this excellent guide, Duck. Very simple to follow, well laid out, etc. I haven't actually done it yet, but I've got everything in place to do so (the flash tool, the KDZ file in the folder, etc.)
I assume once the downgrade is successful, just reroot with Stump, etc and wait for updates via the community?
Will future updates be available via this flash tool, or will they have to be flashed via TWRP? Sorry, I'm just now getting used to the LG G3 dev community, coming from an old GNEX.
Thanks!
continued error when trying ota
I have a problem. I was originally rooted without a custom recovery. I decided to try the ota and got the error message when trying to install. I then flashed this method (kdz) and got back to stock. I rerooted via stump and tried the ota again, failure. I then rewiped and kdz again, this time I did not root. Tried the ota again, no dice.
Any thought? I can flash the kdz fine and get phone to factory 10b but once I try to install the ota I still get the error.

That's odd... You chose cse flash, not normal correct? Normal would not wipe your device and could definitely be the culprit for the ota failing. While cse mode is a complete wipe prior to flashing.
Correct. I did cse, full wipe. I dont know what's going on. I tried atleast 10 times from scratch. I still cant get the ota to install.

After using the method here to downgrade back to 10b and root. I too wasn't able to then S/W update to 11c using survival mode in SuperSU. I perform the OP procedures again and this time didn't root and still wasn't able to S/W update, kept getting error. So I used ---> [GUIDE][HOW TO][VS985] Restore Verizon to Stock to go all the way back. I'm now able to S/W update to 11c and keep root with survival mode set in SuperSU. I most humbly say that there may be a very slight issue with maybe the files here. I truly do appreciate the ability to return to 10b using this method after updating in the first place!
Thanks, ill try the other method and report back. wish me luck. Either way, a huge thanks to duck for the easy way to rerturn. I just wish kdz worked for future ota. It may be a file issue allowing us to revert to 10b but not then allowing future updates.
Use the kdz method then factory reset the device and see if that works.
I tried that. No dice.

Sorry, I missed this question. Yes, any future kdz's that become available will be updated here, along with any changes in flashing methods. Though it's pretty hard to beat the current tool that's available.
And yes, the idea here is to downgrade to 10b and be able to root, unlock, and flash anything you want. Still unclear as to why some want to take the 11c ota, but that's for another thread. The kdz method here is working where the tot was failing for some, and I personally think it's faster and easier to do than the tot method.
The third step might be clarified. Do you mean something like, "Power off your phone completely, then turn power on while also holding the volume up button..."?

You should probably try it before trying to correct it.....
Nope, power off phone completely, hold volume up ONLY, plug in usb cable...it will auto power on into download mode
I have my LG GX2 F430L working perfectly with Sphinx ROM (it's from lgviet forum, sorry can not post link, I'm new). However then I found a guy posted a Lollipop ROM for it, so I tried it. Unfortunately it's a ROM built from Verizon VS880, and after finish updating there is no signal, also Knock On / Off is no longer working. Then I tried many ways to restore the Sphinx ROM but failed for 4 days already. Below is what I have tried so far:
- Root with Drake - Failed
- Root with LG Root Script - Failed
- Root with KingRoot - It said rooted, also rootchecker said OK but can not install SuperSu. Tried SuMe - Failed
- Tried to install CWM in many ways: apk file, flashing by adb - Failed - All the time after I tried Flashify or LG GX2 Recovery app and reboot - it says Boot secure error. As far as I know, bootloader locked and there is no way I can unlock it - There is no OEM unlock in developer option (tried the way with Nova - not worked), and when I tried fastboot oem unlock / fastboot flashing unlock - it said unknown command. Yes I did put my phone to fastboot mode.
So now please help - what could I do to give the Sphinx ROM back to my phone? Appreciate all suggestion as I tried many but still no hope.
Restore the original firmware then reinstall Sphinx.
Thanks es0tericcha0s, I for got to mention that I also tried to flash KDZ by LG Flashing Tool 2014, but always fail at 4%
Ah, yea, sorry, that makes sense since the build.prop has been changed, the flashing tool probably won't work right. Hmm. Weird that the posted this rom without root in the first place... How did you flash it? Via dd commands?
Thank you. When it was in Sphinx, I can use CWM properly and flashed the Verizon ROM that way. So now I guess need to get back to CWM to flash the Sphinx back :crying:
Does root work with Kingroot? If so, you might use a root explorer to change the build.prop to f430l and try the LG Update tool again. There's a new kdz flashing tool called LG Up as well.
Yes, it's rooted with Kingroot. So I'm gonna look for a F430L build.prop file to replace mine? Thank you very much, I will try this way!!!
You wouldn't need to replace the whole thing, just edit the appropriate lines. You could use the Sphinx rom zip one to compare. Make sure the permissions are set correctly or it'll soft brick.
Hello all,
In the process of rooting the phone and flashing careless i managed to flash a H901 ROM on a H960 phone. After noticing the horrible mistake i tried to get back to H960 using several methods but to no avail. Here's a list of what i tried so far, followed by what i think i can try next.
1. Tried getting back to stock using this tutorial. LGUP detects my phone as H901 and won't let me flash H960 kdz saying "KDZ file is invalid".
2. Tried using a hex editor on the KDZ file to change any H960 to H901 thinking it might trick LGUP into thinking it is flashing the correct thing. Didn't work either.
3. Tried flashing KDZ file with LG Flash Tool but it says it can't connect to server and stops.
4. Tried updating it with LG Bridge but that also failed (can't remeber the exact error message, but it wasn't anything specific, just something ambiguous about not being able and how i can try to reconnect the phone)
Now, the good parts:
- i still have access to download mode
- have TWRP installed and working
What i think would work is to get a flashable H960A .zip file so that LGUP will see it as it is. Another idea i thought about is to ask any of you who is willing to help me out with a TWRP backup from a H960 model.
If you guys have any other ideas, i'm willing to follow your instructions.
Thank you for taking the time to read about my mess.
Same problem here, really hoping to get it fixed too
Hex editing will work. Can you ss on how you edit it?
@devcon69 Sure, here: https://imgur.com/a/m5dMg are 2 examples of versions i modified in hex(from H960 to H901) all instances of H960 i found were replaced.
Hi all, i finally managed to undo the damage by editing the hex data on a different KDZ file. Either the first time i tried was on a wrong file or i did it incorrectly. The file i edited now is THIS one. I will edit the post with the modified file for H901 in case anyone else needs it.
Thank you all for the help and attention offered
EDIT: https://1drv.ms/u/s!AurbfgIx--Amk0Q7_l6fX60b0T0Y
Hi.i get Error: Error Code= 0x81300302, MD5 checksum error when i try with u hex editored file. Maybe i have to try to download u file again and try ?
Sorry my foult. Its okay now
Could you enlighten us as to the steps you took that accidentally loaded a H901 firmware onto a H960A device?
Loading H901 firmware onto other V10 devices has been suggested as a potential method for unlocking the bootloader of other devices. This seems risky, but I'd very much like to hear reports of success/failure.
Did your H960A have an unlocked bootloader prior to accidentally installing the H901 firmware?
Hi
Can u make a simple tutorial to how we can change the model in the tot file and what app u use to install the firmware?
i have H961N (Dual SIM) and need to install rooted MM but my model still not rooted, just lollipop, so need to install H960a or any other model has a rooted MM.
Thanks in advance.
What you've typed worries me. There are 3 spots in the file that you modified and changing the third could well cause oddities. I would suggest you try running the command `adb shell getprop ro.lge.factoryversion`.
What is the output of that command? If it is a string that begins "LGH960" then my concern isn't an issue. If it is a string that begins "LGH901" then you've still got a problem.
For folks who wish to get this done by computer, try the "chkdzdev" tool from my LGEtools. This is simply a tool to modify the fields mentioned and should make it possible to accomplish this task without a binary editor.
