Ok so here's the jist of it. Was trying to downgrade from 46a to 10b. Couldn't get LG flash tool to come up "Ready", so I tried the terminal emulator method. Seemed to work until I rebooted. Now I get unsuccessful boot error with the LG screen. I don't have twrp as I hoped, only stock recovery. So I've tried for hours with many different methods to get the Flash tool to pick up my phone when its in Download mode. Tried disabling driver signature at boot, downloading different drivers, changing com port to com41.
Nothing
I am on Windows 8 and could get as far as the actual flashtool previously. Now I cant even get that far. Stayed up until 5am and have been back at it since 1.
Any help would be awesome!

So, I can get the my laptop to pick up the phone and show the port. Also says connected mpt device. I just cant get the flash tool to see it. Would it be safe to say that my phone is wiped and therefore does not currently have a "version" (46a ext) and would allow me to flash a kdz on the 2014 flash tool?
Trying to think outside the box seeing I've gotten no leads....

If by terminal emulator method you mean my thread about manually downgrading partitions, then yes, that's another effect of downgrading them, that you can then flash any KDZ you want.

Ok, I'm gonna give it a try. I'm hoping that I'll already have the flash tool up and it will see my phone in download mode.

Ok guys I finally got it to work! Ran the older 2014 flash tool. The trick I found to make my Asus i7 recognize my phone was a little strange. When i would let my phone boot up it would flash the led red and blue. Once I held the volume button up it would boot to a blank screen, but the phone was still on. This was the only time my laptop would download and install the correct drivers. From there i powered off, went into download mode and connected, then used the lg tool to flash the 10b kdz file.
All rooted and twrp'ed! Flashing 47a and I'm done!
Hopefully, sometime, somehow, this will help someone else with the same problem.
Thanks road warrior for the advice. Been a long 2 days...

About that error, I've read in some threads they said it because busybox. Try to install latest version or replace it with working version. You can find more info by searching.

I think the easiest way is to use LG mobile support tool. refer to this member post http://forum.xda-developers.com/showthread.php?t=2456558&highlight=encrypt
- Boot you phone to S/W update mode
- Run LG mobile support tool (B2CAppSetup.exe)
- Select recover you phone from menu and wait for about an hour
- *Dont forget to comment lg server that you add in host file for offline flash
There're also other way to fix it, if you can boot into Stock recovery by Holding vol- + ... (I can't remember ), but this combo may hard reset your phone if you don't have stock recovery. In stock recovery mode you can use adb to push and replace busybox. I don't try this myself but some member unbrick their phone by this method.

You're on JB rom? Try to flash ICS u-boot/x-loader using Lelus tool first and try again. But for LG mobile support tool it should go pass 15% even if you flash it or not. May be you don't install latest lg usb driver?

Hi guys - I've been an intermediate rooter / tinkerer since the (HTC) G1 days, so I'm feeling very noob right now.
i have a stock rooted vs985 (Verizon G3) on 12b with TWRP recovery. I'd found a link that said Cloudy G3 was working with this version, so i tried installing it, unfortunately in the aroma installer I think I selected the int'l variant. Now, all my phone does is go to recovery. I've tried flashing other roms, restoring back ups, wiping everything and doing the same, no luck. I can get to TWRP and download mode, but I don't have a viable computer option to go the way of LG Flash Tool or the like.
Any options I can use ON my phone via TWRP?

Hopefully someone else will correct this if I'm wrong, but without a computer, no - I don't think there's anything you could do to fix that. Maybe you would be able to use a computer at the library, or use someone else's? You really need to flash the 12B KDZ, or 10B KDZ first if you want to root again after.
Sorry for the bad news, hopefully you or someone figures something out.

In the meantime, have you checked to see if it will still go into Download mode? With the phone off, press and hold the power button and while doing that, plug a USB cable that's already plugged into a (PC normally but maybe it can still be tested with a charger adapter?), plug it into the phone and the phone should turn on into Download mode. If so, then hopefully flashing the KDZ will sort it all out.

My God, man, you're a savior. Used Terminal Command in TWRP. Worked like a charm. Granted it put me on 11C, but at least my phone's working. Not sure why I didn't come across this in my 2 days of searching.
I owe you a craft beer, my friend.
So I rooted and installed TWRP and tried to install the recovery using the app. TWRP said it was successfully installed but will boot to a red and blue flashing led.
I can still get the phone to boot up using power and the down volume button but cant get into recovery anymore. Help would greatly be appreciated.

what firmware are you running? I know anything past 10b or 12b it's kinda a pain to get twrp on it.
35b
I'm sorry but I don't have any experience with trying to get twrp onto 35b. But I know it can take a while but you can tot back to 10b with 35b dll, and then root with stump root then use the twrp app to install twrp recovery

Glad you got it fixed. You *can* put TWRP on from 35B and higher but it's a little painful and some had problems that resulted in them needing to TOT to fix it anyway. I haven't had any problems the 2-3 times I've tested the method. If you're curious you can take a look, it's the second link in my signature below titled "[VS985][TWRP]Install TWRP/flash older KDZs on stock 35B-47A, works for 'ks error'".
But I always recommend the TOT method first.
So I am continous trying methods to downgrade my VS990 (LG V10 Verizon) back to Lolipop so I can get root and change my APN Settings to allow Straighttalk Access. I am using LGFlashTool.
These are the steps I took:
1. Downloaded LG Driver and Installed It (https: //goo.gl/cvsjM4)
2. Downloaded Flash Tool and Installed It (https: //goo.gl/gygzcG)
3. Plug in VS990 and changed Port to 41
4. Ran Flash Tool
5. Selected Manual Mode
6. Under DLL file put LGUP_8994.dll (https: //goo.gl/u2Cr1g)
7. Under S/W put rootedsystemvs.tot (I couldn't find the stock TOT so I put this one) (https: //goo.gl/Sh20Pr)
8. Selected UPGRADE DL and BOARD DL (Same Outcome) and Clicked Ok.
9. Clicked Start.
10. Removed device from USB for 3 seconds and plugged it back in.
11. Let it do its job till it FAILED.
Im just updating what I tried. Maybe some DEV can use this. I would love some help!

The bootloader was updated. You can't downgrade. Even with root, you can't downgrade. You would need a completely custom bootloader, or the old bootloader.

Interesting. Im guessing obtaining the bootloader is impossible since Verizon thinks it has the ability to keep hold of open-source material. Ridiculous.

Tried with an older computer 32bit with usb 2.0 and it did the same thing. Toolkit said "VSB98546A is not supported," also tried the toolkit to instal twrp and it gave the same warning. LG flash tool fails because of model check. When you scroll up next to model is blank.
I also tried flashing a kdz using lg flash tool 2014 and it was jsut question marks. The status bar would go across on screen then nothing. Nothing ever changed on phone.
First things first. With the phone in download mode and connected to the PC via USB, when you look in Windows' Device Manager, do you see the phone listed in the Modem section?

The only KDZs you can flash from stock 46A are 35B or 47A. If you want to get to where you can easily root and install TWRP, you'll have to flash the 10B TOT using the .DLL that's extracted from the 35B KDZ, then root using the Stump app and use TWRP Manager from the Play Store to flash TWRP. Then you can flash whatever bootstack and ROM you want.
You can get the 10B TOT and 35B .DLL from my Android File Host link at the bottom of @annoyingduck's stickied return to stock thread in the General section. You'll have to Google for the software to flash TOTs.

LGVS985_20140620_LGFLASHv160.dll Is this the right dll file?
VS98510B_03.tot
I did more reading and it seems not using an LG cable can cause this. I tried with many brands but don't have an LG cable. If those are the correct files I guess my next step is to order an LG cable.

I can't tell by the filename alone if it's the right file. You can compare to what I have on Android File Host (link in the thread I mentioned).
The TOT file is likely correct. Yes, I always recommend using the original USB cable for flashing. Hopefully that's your solution.
Thanks so much for your help. Looks like I was using the wrong dll file. I used the one in this post below and it worked right away.

I had the same problem and was able to flash an old rom using the LG flashtool, here is a guide:

But I had to use this dll file:

After my phone reset during the flash it displayed 2 on the screen and did not pass. Just go into your PC's device manager and recheck the com port and change it back to 41. Mine changed as the phone reset during the flash process. Once I changed it back to 41 the flash resumed and the displayed 3 on the phone and the computer said pass.
MY Problem Has Been Recoverd By Flashing 35B KDZ using LG FLASH TOOL 2014. Easy and not need of any DLL file. Now i am on 47A using KDZ.
Thanks everyone
