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!
Error: 00000064
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.

Nope, we can still extract a copy of it with root, we just can't flash over it

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...

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.

Thanks. I tried that too and got "model information check fail." I used these files:
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:
http://forum.xda-developers.com/showthread.php?t=2772199
But I had to use this dll file:
http://forum.xda-developers.com/showpost.php?p=63266194&postcount=84
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

1. Download kdz file from here: https://docs.google.com/uc?id=0B3R77elw9JjNSmVsVjhjbWdLcEU&export=download
2. Download lgup from here: https://drive.google.com/file/d/0BzRiXiP57hD7bnpaVkJJUUFLQnc/view?pref=2&pli=1 and install both file in it. After that Copy the "common" folder in the zip file to "C:\Program Files (x86)\LG Electronics\LGUP\model"
3. Download and install LG Bridge for drivers. http://www.lg.com/us/support/product-help/CT10000026-1438110404543-preinstall-app
4. Turn off your phone, hold volume up button while plug your microusb cable, It will set your v10 to download mode.
5. Run lgup executive file, chose upgrade, in bin file select the kdz downloaded from step 1, then CLOSE lg up.
6. Reopen lgup again, chose refurbid, the kdz file still linked in bin
7. Press start and wait. When it finished, u're on stock MM v20e.
Perfect! Thank you. Do I need to relock the bootloader after that or will lgup do it for me?
I used lg bridge and clicked recovery button on bottom right then locked bootloader. Worked like a champ for me

Nobody reads anything anymore. The thread that was linked literally has a pdf in it called "how to unroot"
When these unroot methods are applied, do they get rid of the "your device software cant be checked for corruption" prompt on bootup?
I think only relocking the bootloader removes that message.

I ask because I'd like to trade in this phone for the V20. I just don't want to embark on all this effort and still have a phone with "root evidence" making it un-tradeable.

flash the phone with root stock and then while in fastboot mode run the following command: fastboot oem lock
That will lock the bootloader and get rid of the annoying message.
And with that, i can only flash the phone using what's local since i cannot connect via usb, and i'm also stuck on lollipop and want to upgrade to MM. Is there a zip that i can use to flash to MM, and still keep root at the same time?
Any help is greatly appreciated.

Use your computer to put files on a micro SD card. Put card in phone.
OR
Use one of many wifi file transfer apps on play store. Sambadroid is a good one.
The issue is not getting the files to the phone, i can use google drive, etc... once there how can i upgrade to MM, because the usb port is fried and i cannot hook a cable to it.

You can use Eliminater74s rom and just flash it using TWRP. There's a Part 1 & 2.
Read his OP on what to do and dont mix V20E with V20J ... Read before you flash anything. If you have any doubts then ask or re-read everything again.

That's the bad part. You can't boot with root without 'fastboot oem unlock', which is done with a usb cable. For more info read up on the root process of the first MM update, 20e. (http://forum.xda-developers.com/tmo...1v20estock-customized-t3360240/post67328874). To me it sounds like you are stuck on LP to stay rooted.

The upgrade to MM relocks the bootloader (either .zip or .kdz), to unlock the new bootloader you unfortunately need a usb cable. Early updaters that used the .zips couldn't boot locked bootloaders with root. Unfortunately (for you) to use MM with root you need to unlock the bootloader with fastboot all over again.
Sent from my LG-H901 using XDA Labs
theres no wireless adb or fastboot? i've unlocked and rooted in LL - so you're saying it relocks in MM? Also i can't follow - which do i need, lhave a v10 and can't find info on whether i have a E or J. If this is in waste, i may buy a new phone, issue is whats comparable these days?
so in current state, if i flash MM V10_H901_V20E_Stock_MM_Rooted-signed.zip (i assume this is just a stock whole package, during this process it will relock the phone, and because its mm, i will not be able to use the phone, or can i still use the phone maybe go into twrp and run the unlock command?i mean if there is no way, then i'm stuck @ 5.11, and time for a new phone

That file is only part2 of the V20E zips. V20J is just the second MM update from LG. I am in the middle of resetting up my V10 after my own upgrade from LP to v20J MM, and yes i needed to use fastboot with a usb cable to re-unlock the bootloader as instructed by the part1 zip. So to say lightly, your V10 is stuck on LP, unless you send it somewhere to be repaired. If you want MM WITHOUT root you could flash the kdz, which will also leave your data intact if done as an upgrade, or wipe if done as refurbish. (rooting a kdz flash can only be done with a usb cable.)

I have followed this method, and got rooted without issues.
I've trird using mfastboot, sdk tool, abd/mfastboot.. Nothing seems to be working. I'll get most of the way thru. When I try to flash the twrp, thats where the problem starts. It just won't flash. I've used the necessary drivers for my T-Mobile LG V10 H901. But every time, it just will not flash. Do I need a flash tool kit? Serms I'm missing something.
