[Q] help with downgrade to VS985 10b - G3 Q&A, Help & Troubleshooting

Okay so I'm trying to downgrade from VS98512b to VS98510b
I've tried both the tot and kdz methods
Tot problems:
I connect the phone in download mode and have to manually "update driver" there are a lot of options for manufacturer and model when I install the driver.
this leads me to my first question: Which driver do I install?
there are 3 separate "devices" my computer recognizes (1) a MTP USB device (2) a LGE Android Phone and (3) a CDC Serial. (All of these devices have the yellow exclamation point)
what I have done is chosen the "CDC serial" device and installed (and tried to use) the drivers titled
"LGE mobile USB serial port"
"LGE AndroidNet for VZW USB serial port"
"LGE AndroidNet USB serial port"
this removes the yellow exclamation point from the serial port but none of these drivers have worked. and When I say "not worked" I mean that the lg flash tool readys up, and I unplug and plug the phone in, and it says "Waiting for connection." It then does nothing. I've stared at it for as much as 25 min before I've given up. and before anyone asks I've followed all the directions and set up the com port to port 41
SO....
Do I have the right drivers?
Do I need to install drivers for the "MTP device" and/or the "LGE Android Phone"?
if so which drivers do I install for those?
KDZ problems:
I have less info on this because after I select "start" the installation window has only question marks as text. but basically I get stuck in an endless loop where I hit the "???" button and the loading bar goes to 4% and it stops and I have to hit the "???" button again.
just for s**ts and gigs I tried hitting "read phone information" before I hit start and it says something along the lines of "imei empty imei auth fail... please check imei value"
Any help is appreciated!

If anyone knows how to solve this could you please help me. thanks
Is this the driver package you installed?...
LGUnitedMobileDriver_S51MAN312AP22_ML_WHQL_Ver_3.12.3.exe.7z

And no disrespect intended Matt, but you're in download mode when viewing the device in Device Manager?

[Q] VS98512b downgrade with FlashTool stuck in "Waiting for connection"

I am trying to downgrade my LG G3 VS98512b so I can root it. I am running Windows 7 Professional Edition in a VM on an elementary OS host. I am following this guide: androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html
I have gotten to step 19, but I cannot get past the "Waiting for connection" stage. The device manager tells me "This device cannot start. (Code 10)." It does this shortly after FlashTool starts waiting; before that, the device is working fine.
I believe I have correctly installed all of the drivers I need, and I am using the LG connector that came with my phone. I have no idea what the problem is. Please advise.
I had that problem when you get to waiting for connection unplug usb lead from phone then reconnect it and it detects it and finishes the job.....
Sadly, that isn't working. When I try unplugging/replugging the first time, I get the waiting message. If I try again while the message is up, some more messages flash by and FlashTool says "Download FAIL!! (0 sec)." The other messages are
Code:
PID: NULL
IMEI: NULL
Model :
DLL : VS985
BIN : VS98510B_03.TOT
SWV :
SWOV :
Model Information Check FAIL!
00000000
This all happens within about a second of unplugging my phone. I've tried using a different USB port on my computer, and I've tried waiting varying amounts of time between unplugging and replugging my phone. While this is happening, my phone doesn't change at all; it just keeps the "Firmware Update" screen. I'm also using VirtualBox version 4.3.26, if that makes any difference.
I have the same problem !
Did u fixe it ?

[Q] LG G3-D850 Not Recognized By PC, Need HELP

When I plug the USB into my G3 I get "Other Devices - Android". If I try and install the drivers from an install of this: LGUnitedMobileDriver_S50MAN311AP22_ML_WHQL_Ver_3.11.3, I go and tell Windows I will select the driver it onl;y gives an option as an ADB Device. But there is no selection for an "LG Android Composite Device" (or something along those lines).
I am stuck with Fastboot Mode Started and can't do anything about it.
Anyone have any ideas?
On your Phone go to Settings > More Settings. Chose USB utilities and tap Connect Storage to PC. You might be asked to unplug and plug your Android device in order to install necessary drivers. After you've completed all the steps, check if your Android phone is recognized.
Check LG G3 Manual- guideusermanual.com/product-name-lg-g3-manual&po=134051&lang=English for more support.

[HELP] G3 Hardbrick Help! URGENT!

Here's my case:
I've got a LG G3 F400L (Korean LGU Variant), its on Marshmallow(6.0), and for all I know I used the Autorec program for Lollipop, and apparently got my bootloader corrupted; No led flashing, no display. But the Qualcomm 9008 serial port is shown on the device manager and I can use Boardiag to detect it. I know, irony and idiocy made this dilemma.
Diagnostics:
I've used Boardiag 2.99a by willcracker and yes I've checked "AP check" and "EMMC TEST" and both are tagged as "Pass", but when it comes to the "SDRAM TEST" it throws off an error indicating that there is a flash error on partition "boot" along with a 0x3000 and I can't progress beyond that, I've also tried to use the "Restore Device" option to revive it but still the later error still persists.
I've also tried Smart Boot Diagnostics but the problem is that my device's AP Chip doesn't exist on the current version of the tool.
What I would like to press on:
I would want to resolve this on my own and that no amount of suggesting on sending this to the service center would yield fruit. Please do understand, I would also like this to be a thread that can help me and other on resolving their corrupted bootloader units.
Please, can someone help me on my dilemma. Thank you very much. Any amount of help is appreciated.
Try using board diag with the battery unplugged.

Already tried that but still nothing works.
Current situation:
Alas, I've accessed fastboot and had wiped the boot partition, but now the USB is detected as "LGE AndroidNet USB Serial Port."

You need to short with a cable internet connection I do this last night and changes for Qalcomm USB in the same time...After that, you need to open BoarDiag and do the process. If you canĀ“t enter in download mode, you need in BoarDiag pass the USERDATA
I follow this link: http://open-freax.fr/guide-unbrick-your-lg-g3/

OP3 not recognized on Win10

My oneplus 3 isn't found in com/ports on windowsill 10. It's unable to load recovery and won't boot to system. Fastbook still works and has a unlocked boot loader. Trying to install stock firmware to restore the device for se again. Any help would be greatly appreciated.
Try loading drivers, have no issues here. Also run cmd prompt by right clicking on cmd.exe and selecting "Run As Administrator"

Ok. Thanks. I'll try that once I'm back home. But the drivers have been installed several times with no sucess.
Also make sure USB debugging is enabled in the developers settings and you have the correct USB mode enabled (not charging)

If you have still have no luck it may be worth showing whats seen in device manager when OP3 is plugged in. (Possible unknown device)
Don't have any issue with WIN10 myself along side OP3 but have had numerous driver related issues on other devices with WIN10

here is the device manager
setup driver and try in twrp
A few pointers:
Is this a "home/personal" computer - USB devices can be prevented from connecting via registry hacks and the Group Policy editor ( wonder if some av software could require authentication???).
With Windows 10 you should have native "Microsoft" drivers and no external drivers need to be loaded,
It should be detected when the usb connection is "charging" and you should see/hear Windows "changing" drivers as you change the usb connection to MTP,PTP,Midi.
I presume you've tried different usb ports and if possible alternative cables
If you plugged in the OP3 powered off and then switch it on then it should be detected by Windows before Android boots - otherwise you could never connect a bricked device or follow Oneplus.net flashing instrutions (connect device booted in recovery mode)
Try running USBdview from http://www.nirsoft.net/utils/usb_devices_view.html Note 32 and 64bit versions!!!! The program will show all usb drivers that have been used and show which ones have their device connected. You can select and delete drivers. You can see which drivers have been used for the OP3 by looking at the Vendor and Product Id's (VID/PID) columns . OP3 has a VID of 2A70 and a PID of 9011 (may be others). If you have in the past connected the OP3 on the computer then look at the Hub/Port columns this shows the USB socket that worked.
In Device Manager I would expect the OP3 "out of the box" to just show up under "Portable Devices" as "ONEPLUS A3003" and with usb debugging enabled as a second entry either as an ADB device under "Android devices" or as "ADB interface" under "Universal Serial bus devices" You said that "Fastbook" worked - Did you mean Fastboot? - if so then the device should be showing up somewhere in Device Manager. Try "fastboot devices -l" for any clue.
Thanks. I'll give those a try tomorrow. Just to mention in case I wasn't clear with my info. The OP3 can't boot into recovery. It'll say oneplus powered by android then a blank screen. And yea, I did mean fastboot lol. Thank so for all the info also. I'll post what I discover asap.

One more thing. Connect the phone to a USB 2.0 port and not a 3.0 port. It may not be recognised in a 3.0 port.

This is what I found on USBDeview. There are two other versions of the OP3 on this list. But they do not show as being connected while the phone is in Fastboot. Im unable to access the OS to enable anything that may help with it being seen on my computer.

This is what shows up after the one plus boot logo appears.
I had similar problem. I was rooting my 1+3. I went to device control settings in WIN 10 and removed 1+3 drivers. Next time when i was in fastboot mode windows installed drivers. :highfive:
I used the ones that came with 1+3
