Hello, my attempt to KDZ flat out failed early on 5%~ and now i can only enter the LG Boot Logo Screen and System Recovery Screen, Download Mode no longer shows up, and offmode charging has not been able to establish a percentage, anything else i can try? or should i take the chance and walk into a verizon store? (Just got the phone on the 7th of January)
[Verizon LG G3] pacedrum69:
Just did this finally. After having driver issues, I reinstalled, and it worked perfectly
[Verizon LG G3] jkbane:
SOLVED

I cant seem to get the tool to work. It keeps saying USB not connected. I tried to change ports and cables. Still no luck

It's working.. Just let it do its thing... Watch the phone, not the comp screen. Your phone should start updating after about 5 minutes. Same happened to me

Does this method work for downgrading from vs98512b to 10 on Windows 8.1

Firmware update

switched out the USB and it worked well.. its still going for me
[Verizon LG G3] Jake Lessley:
Ok shoot me or help me... so I was go impatient to just let the LG flash tool run its course when saying, "usb not connected please plug in device" while trying to flash back to vs98510b Aperenly it kicks in after about 5min after learning that I jumped back on the laptop & went to flash back to 10b & let it run after saying I wasn't plugged in & now it's saying there is 2 devices plugged in via usb to unplug one & retry??? I'm so flustered with this whole ordeal if u were rich I'd give someone a million dollars to figure this out for me. Lol

Is there a mirror for the KDZ file? Download keeps failing...

Well...found the mirror. Not usually this dumb. *crawls in hole*
[Verizon LG G3] abexman:
Argh. OK, I am getting a "Connection to Server Failed" error. Is this a setting in the tool somehow? I am using a virtual machine and reloaded my VM from scratch so I don't this is related to playing with the tot - this VM does not have that tool installed. I saw some prior messages in this thread regarding a "communication to server" error - I assume this is the same error?

I don't know what else it could be. I checksummed the kdz successfully. The device manager installs except for the MTP has a yellow flag. I have the phone on COM port 41. I did switch the dialogue in the flash tool to English. The phone itself always stays on "Firmware Update" at 0% thru the whole process. Is that working right? If I unplug the phone the tool definitely gives me a different error. I did install both the drivers (generic and vzw) - since a poster earlier said he did this to overcome the comm to server error.

Maybe I need to use a newer version of the generic driver? I could not find an original source online but did see some 3.12 versions of that - though it does seem like maybe I am not supposed to need the generic driver, only the vzw version? Do I need a certain reboot sequence? Should I clear out my registry or something?

Some suggested waiting beyond the message - but nothing happens - the tool itself simply stops and asks if you want to retry. Is that deceiving?

[Verizon LG G3] annoyingduck:
There are several users showing the same error in the original modified flash tool thread I linked. The predominate reason for the error appears to be driver related. I simply just don't know why there are so many errors, there may be a problem with current drivers and the tool "may" need to be updated.?? (just a guess), I'd go ahead and post in the original tool thread for some clarification.

Also, OP updated with mega link mirror.....sorry, forgot to add that to the before!
[Verizon LG G3] cjchevez:
Sometimes when the flashtool has been acting up and left me

With a phone that never finished flashing the LG mobile support tool

Has been a life saver. I believe u can chose update device or driver (forgot)and

Will flash the phone when the flashtool failed me . Its worth a shot!
[Verizon LG G3] roirraW "edor" ehT:
^ What I was going to say.
[Verizon LG G3] abexman:
What's the best way to get that tool? I saw another thread on the Optimus where they said the tool was hacked and had a virus?
[Verizon LG G3] IaKnightHawke:
Do a Google search for it. It is a PC tool. Not found in the play store. Hope this helps.
[Verizon LG G3] abexman:
Every step I am rebuffed! There does not seem to be a vs985 option to intall the driver at least when selecting Verizon as a carrier. Am I to use the tool's recovery or upgrade mode?
[Verizon LG G3] cjchevez:
Your phone needs to connect first man, try updating the lg and verizon drivers.

Then make sure youre connected via usb, maybe try another cable.

Try the tot method, u got nothing else to lose

Edit

Did you lose download mode?

There was a adb way to get the g2 to regain download mode using fastboot commands. http://xdaforums.com/showthread.php?t=2582142&page=7 , do some research for the g3 it maybe similar to the g2.

If you still have download mode keep trying youll get it.

Worst case you can buy a used motherboard and swap it.

Good luck
[Verizon LG G3] annoyingduck:
*OP Updated*

Official 12b kdz file added to allow OTA compatible restoring. A few notes:

-This WILL allow OTA updates, as this is the current 12b firmware

-You CANNOT currently root or unlock (bump) while on this firmware

-You CAN downgrade back to 10b if you flash this

-You need to use the 10b file for rooting/unlocking
[Verizon LG G3] abexman:
OK made progress here. I think my USB virtual machine USB settings were wonky - even though I had only the LG plugged ino the laptop; there were two other USB devices unknown to me which seemed to be "blocking" the right connection to the G3. I noticed the connection which was hanging in the flashtool became active after I activated one of the other USB devices. So abandoned it rather than tinkering more, and used a new laptop with kdz tool - and success! Mission accomplished. Thanks to all the helpers here! Viva la kdz!
[Verizon LG G3] roirraW "edor" ehT:
Glad you got it working. Indeed, trying to do these kinds of things through even professional VMs such as VMWare Workstation is risky and unreliable.

[Verizon LG G3] Gil81:
Thanks all..worked like a charm..after a little hiccup. It stalled at 7%. I just ran it again a good to go. Have root now, so looking to twrp. Thanks again.
[Verizon LG G3] GhostStache:
I get to "S/W Upgrade is in progress" and it sticks at 4%, then jumps to 10%, and after 5 more minutes will go to 11%, and then my phone will be at 1%, and then it times me out and gives me a retry message. I've done this 10 times now and spent hours trying to get it to work but none of the solutions in this thread have worked for me thus far.
[Verizon LG G3] jasonrusso77:
A little confused

Please forgive my ignorance, and if I missed soimething please point me in the right direction so I can read it myself.

I have a G3 on 12b. I fully understand how to back-flash it to 10b. Run stump-root, TWRP, etc. After that is all done, am I supposed to update it to 12b with the file I downloaded here? Will it keep root and I have to disable the OTA updates?

I'm new at this so if I need to read something somewhere else just point me there.
[Verizon LG G3] annoyingduck:
Not quite, but there are several ways to do it depending on what you ultimately are looking for.

1: The easy custom way (recommended): use the 10b kdz here, root it, flash current bumped recovery (twrp preferred). Now your ready to flash whatever you want on it and you don't have to worry about OTA's because they will fail anyways due to the custom recovery and other reasons noted in this thread. From here if you want to be on "stock" 12b you need to flash the 12b radio that's in both of the skydragon and jasminerom threads, then there are 3 stock based 12b roms you can flash skydragon, jasmine, and eclipse. Nitro (eclipse) has a pure stock 12b deodexed rom on his afh page here: https://www.androidfilehost.com/?a=show&w=files&flid=23585 which is closest you'll get to stock by manually flashing. Oh yeah, and all aosp and future rooted stock LP builds....

2: The other custom way: use the 10b tot method, root, flash recovery, same as I just posted above

3: The stock way: use the 10b tot (not the kdz, because our 12b kdz will not take ota's), root, do NOT flash custom recovery, take ota's up to current. You'll be rooted, odexed, on current firmware/modem, ota vulnerable, but you can freeze "system updates" if you don't want future updates.

4: Alternate method: use either kdz or tot to 10b, root, flash recovery, flash each system partition you want individually using the methods covered/linked here: http://xdaforums.com/verizon-lg-g3/general/reference-stock-img-files-t2966958 end result is pure stock, root, custom recovery, ota vulnerable

-Flashing back to 10b/rooting then flashing the 12b kdz in normal mode will cause you to lose root, hopefully that answers your questions
[Verizon LG G3] jasonrusso77:
Is there any reason to upgrade from 10b to 12b? Anything noticible?
[Verizon LG G3] annoyingduck:
It's smoother, few new features. I would. Definitely flash the modem either way.
[Verizon LG G3] jasonrusso77:
The "modem" is the radio, correct? You said in your previous post to flash the radio.
[Verizon LG G3] annoyingduck:
yes, same thing
[Verizon LG G3] jasonrusso77:
And I can do that through recovery after I install TWRP, correct? I'll probably go to 10b, flash the modem, then flash skydragon.
[Verizon LG G3] annoyingduck:
Second post updated, as I have had some time to play with windows!! I found several of the issues users were having since I clean installed Windows last week. Anyways, I manged to figure it out easily. This is not rocket science, this tool just works. The main issue is definitely driver related.

*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.
[Verizon LG G3] evocop:
Thanks a million... I received my replacement with 12b. Followed instructions and boom, back to 10b, rooted with ioroot, bumped with twrp. !!!

Can I flash 12b kdz as normal flash and maintain root? because, Like stated in op , I can't take otas from this 10b kdz.

Also I have a twrp backup from 12b transferred to my new devices storage but when I tap restore in twrp, nothing is shown, is this because the backup is from 12b and I am currently on 10b? Or because my twrp backup was from twrp 2.8.5 and I currently have twrp 2.8.0?
[Verizon LG G3] annoyingduck:
root will be lost if you kdz up using normal flash. Just flash twrp 2.8.5 in recovery, and be sure you transfered the backup correctly. Or just make a backup, then transfer your backup to that folder under the new id
[Verizon LG G3] roirraW "edor" ehT:
No.

You'll have to download the 12B boot, modem and system (and recovery just in case for the future) .img files and use [MENTION=2684188]autoprime[/MENTION]'s Flash2 zip files to flash them.

Might as well update to the latest TWRP first.

Don't know for sure, only trying will tell (upgrade TWRP). Did you tap on TWRP to change between internal storage and your MicroSD card?
[Verizon LG G3] evocop:
Ok I flashed twrp 2.8.5, still no sign of my backup when I tap restore. I did change directory from internal to external.

I will flash 12b files as directed (flash2 zip) and see if the backup appear then. I'll let you know, thank you for the direction.. It will be later today when I get off work.
[Verizon LG G3] roirraW "edor" ehT:
More than likely, @annoyingduck's advise is what you need to follow. It makes sense. Flashing the 12B files won't make the backup appear. As he said, they're probably just in a folder that's named differently than TWRP will name it now (because of your device ID). You don't even have to create a full backup. Just backup boot, for instance, to internal. Then use a file manager like X-plore to move the backup from whatever folder it's in to the folder on your internal that was just created.
[Verizon LG G3] evocop:
yEEEAa! It worked, I could not copy my backup from external into internal twrp backup location, for some reason it failed halfway, I tried to delete the failed copy and it would not delete either. I am using root explorer (yes with root access.) I went into twrp and used the file manager built in and deleted the failed partial copy, recopied from within file manager to twrp backup location, it copied successfully, I crossed my fingers and restored! After a longer than normal (almost scary long bootup), my restore was complete! Let it settle for a few minutes and super smooth just like before. Thank you fellas , I didn't think about the backup having a specific device ID. Can't thank you enough
[Verizon LG G3] roirraW "edor" ehT:
Nice! Glad @annoyingduck and I could help. That was good thinking about TWRP's file manager. Have fun!

Oh, I always use Titanium Backup to restore my previous device ID each time I flash a new ROM or anything like that. It automatically warns when the device ID is different the first time you run it on a "new" ROM.
[Verizon LG G3] raceguy23:
I followed all the directions and went back to the 10b software, and I do not have root access. Am I missing a step?

---------- Post added at 05:32 AM ---------- Previous post was at 05:08 AM ----------

Is there another step after this rollback to gain root access? I was able to rollback successfully, but root checker and titanium backup say I do not have root access.
[Verizon LG G3] roirraW "edor" ehT:
Any stock build isn't going to give you root, you just have to be on 10B before you can root. Stump is what will root your phone under 10B.

im flashing the 12B atm and my phone has COM6 in green and the progress bar is stuck at 17%

also had a popup saying "the exception unknown software exception (0xe06d7363) occourred in the application at location 0x7543c42d. im gonna click OK...

also the widows with ????? all closed out before it poped up. the only thing that wasnt "?????" was "USB"

when i first started the driver for LGE Android phone or LGE AndroidNet for VZW USB Serial Port COM5 failed, so when i tried to manually install, i didnt see it, so i re ran the driver file, and yeah...

okay, well, i re ran it, and all the ??? turned to words, and i discovered exactly why it stopped at 17%.. a pop up popped up and it was all ???? and i just clicked ???? thinking "yeah i needed to do that", but no... it canceled it. but now im good. it booted, but however it froze at 99% and said it stopped working, and then it just closed out, but it booted up, reset, and now im at the setup wizard... HERE I COME LOLLIPOP!

I just bought a g3 with the 12b version and I want to use bump can someone please tell me if I'm in the right thread to do so that way I can have root and a custom recovery I know you can on 10b but what do I need to do to get the 12b to be able to use bump Thanks
[Verizon LG G3] phillymade:
You are on the right track. Follow the OP and flash back to 10B, then root using Stump Root, then using Flashify (Google Play Store) flash Bump! TWRP (now you are rooted and unlocked). On completion it will boot you into TWRP. Here you can flash whatever 12B or ASOP rom you like. I would also recommend you flash the 12B Modem as well. (this is a one time flash to update the radio to the 12B radio)

For Stump Root go here: http://xdaforums.com/lg-g3/orig-development/root-stump-root-lg-g3-sprint-verizon-t2850906

I absolutely cannot figure this out. I have literally been trying to get this to work for 4 hours. I have installed the drivers and followed the instructions to the strictest detail. The error I'm getting is attached to this post. This is getting very frustrating and I very much thank anyone who can help shed some light on what's going on here.
[Verizon LG G3] roirraW "edor" ehT:
Hi! Reboot the computer, try a different USB cable and USB port. If he USB port you are trying is USB 3.0, try a USB 2.0 one.
[Verizon LG G3] AgentJohnson:
I've tried all the above. I've switched ports, uninstalled/reinstalled drivers, tried different versions of drivers yet nothing seems to work. I've even tried the same process on a different computer with the same results.
[Verizon LG G3] roirraW "edor" ehT:
I wish I knew what else to suggest. :(

You let the driver's load all the way once you plug the phone into the PC, right? Check in Device Manager all the phone-related entries don't have exclamation points on their icons?
[Verizon LG G3] tgoods24:
is this normally a long process? Time Elapse at 17 min and phone says 3%. Im using the original cable my computer has a i7/ssd.
[Verizon LG G3] annoyingduck:
Ate you sure you didn't install the verizon lg package that it prompts you to install when you first connect the phone. Your symptom is that of having other lg tools installed.
[Verizon LG G3] AgentJohnson:
Yep. The phone is showing up as the android net device like one of the other posts stated.

I uninstalled everything involving mobile drivers from add remove programs and installed the specific Verizon/LG driver in the OP. It' recognized in device manager as the correct type of device. It has to be conflicting with some other software installed but I can't find anything else.
[Verizon LG G3] roirraW "edor" ehT:
Did it ever progress? It should normally be maybe 10 or so minutes, I think.

Sent from my VK810 4G
[Verizon LG G3] annoyingduck:
I'm guessing that there are many factors that will determine the overall speed of how this works. For me, it's approx 3 min from start of tool to reboot.... I haven't experienced the long delays.
[Verizon LG G3] zakkyzombie:
I actually got stuck at 17% because I couldn't read what the thing was saying due to all the "???", but when I re-tried it was in English and there's a popup saying it connect to servers and wants you to cancel. Don't click ok. It stops the flash and you get stuck. Just drag it away.
[Verizon LG G3] netookska05:
Its in English the second time when you interrupted it the first time bud!!! You should have let the phone do its thing such as restart!!!

[Verizon LG G3] tech_head:
I tried KDZ on my phone and could never get it to work.

I switched to the TOT method and was able to be done in about 15 minutes.
[Verizon LG G3] XxCrockxX:
Just an FYI, I had it connected via a USB 3.0 Port, to which it said COM4, not COM5, and was crawling at about 1% every 15 minutes.

So naturally I decided to ignore the warning, pull the plug, put it in the USB 2.0 and presto, COM5 and done very snappily.
[Verizon LG G3] rspong:
So bottom line, I can simply kdz straight from 23a to 10b? Knowing I will loose data? Im very interested in skydragons new offerings...
[Verizon LG G3] Syzergy:
Can confirm this works from 23A to 10B. I didn't see it anywhere on this thread and wasn't too sure about it. Its working fine though. Time to root!
[Verizon LG G3] Edde3d:
Just curious about something. I was on 12b then rolled back to 10b and rooted with stump. All is well now but from what I have noticed I'd like to be back on 12b. My phone is now telling me there is an ota update which I'm sure will get me back to 12b. But will the ota wipe my root? And should I just go about it by 10b to 11c then 11c to 12b. Thanks
[Verizon LG G3] bweN diorD:
it is very rare to loose root on the way to 12b. you should be fine just taking the ota's.
[Verizon LG G3] annoyingduck:
The ota will fail unless you use the tot method. Best bet, flash Nitro's stock 12b. Only thing different from stock is it's deodexed (nice) and has the external SD patch included (nice). Get it here https://www.androidfilehost.com/?a=show&w=files&flid=23585
[Verizon LG G3] Edde3d:
Awesome thanks. It's been a while since i have flashed anything really. This method above can be done thru twrp and just select the rar right? And i want to wipe everything?
[Verizon LG G3] Mettlegear:
LG G3 VS98512b

So I just bought this phone yesterday and found out the 12b is unrootable currently. This is the Verizon version and i am wondering if rolling back to 10b is still possible using this method?
[Verizon LG G3] annoyingduck:
Read the op. Your answer is there
[Verizon LG G3] Edde3d:
I just had to do exactly what you asked Mettlegear. Yes it works.
[Verizon LG G3] Mettlegear:
Thank you! I would have taken the statement "works on all variants" as fact but over the past two weeks I have read so many posts that later say "oh yeah doesn't work for the Verizon one" :(
[Verizon LG G3] Javayes:
I used this thread to successfully go back to 10b from 12b then root, installed twrp....cm12. Thanks.

I also flashed the 12b modem and that fixed LTE. But what about the other 12b partitions? Like rpm and tz? I ask because I had to do that kind of stuff on my old galaxy s3 to solve some bugs. The only thing nor working on my lgg3 is wirelees charging and I wonder if having these very old 10b partitions could cause the problem. Does anybody know? Did a nobody try to flash the 12b tz and rpm or other partitions other than the modem without losing root or bricking?
[Verizon LG G3] bweN diorD:
you dont need those other partitions updated really. i ran L roms on 10b for months without issue.

wireless charging works on 0 non stock based roms. has nothing to do with the partitions, its a kernel issue.
