Download:

Credit to @hyelton for the original write up in the General section here.
Install:
1. Install the LG drivers downloaded above.
2. Install LGFlashTools v1.6 (but don't run it)
3. Extract the TOT and .DLL file from the ZIP
Drivers initialization:
1. Put the phone into download mode. (Turn off device PRESS VOL UP while plugging in the micro usb cable. If this doesn't work, try holding both volume keys instead)
2. Let the phone initialize and install the drivers. Once done, in Device manager, you should see the LG phone listed under COM ports (something along these lines).
3. Find that LG entry in Device Manager, click on Properties, Advanced and then change the COM port to COM41 and close/save.
4. Unplug your phone! Important step.
LGFlashTools:
To get this tool to work, you'll need to do a few tricks.
1. Set the computer's date to some time in July 2012 or before.
2. Disconnect the internet
3. Find a serial number or register key from somewhere on the web (a google search for lgflashtools serial will yield some results). Can't help you here and please don't share any keys in this thread or get us in trouble.
4. Execute the LGFlashTools. It should ask you for a key, put it in. Now you should see a dialog where you can load the DLL file and the TOT files that you extracted earlier. Put them both in here. Click ok
Flashing:
5. There is a yellow arrow on the top left. Click on it to initialize the process. Once done, it should say "ready/finished" or whatever.
6. Put the phone in download mode again, and plug it into the USB port. LG FLash Tools should start flashing it automatically. When it's done, it'll automatically reboot into your stock AT&T rom and all of your data and internal sdcard files will be gone.

I believe you can flash this from D80010o. I think I did it once to verify, but it was a long night. There is no root or recovery unless you count the stock one.Yes and yes.

@srk_srinivas, this does wipe your phone, so be sure to backup first. I know it's been said before, but I've seen people miss that point many times.

I'm looking into getting the 10q update. So like you said. We can root 10q and the take the OTA D80020c update and hopefully keep root.

Before you start any actions to modify the phone, you should get it repaired by the vendor. Its not even a year since the model was released, so you should have still guarantee on it.

Bump! unlock your bootloader, then you will be able flashing roms via recovery. BUT its really risky if your phone has no working USB port as you cant flash the stock firware if something goes wrong.

Just follow my LG G3 back to stock guide if you wasn't already.
That error usually means your using a USB 3.0 port. Make sure your using a USB 2.0 port only!
The tot method is the ONLY back to stock method for AT&T LG phones.

Sounds like you need to place the lg g3 megallock.DLL in the lgflashtool directory.

Wait what? Flash tool won't even open if that's not there. So it's not that. Also it's a generic megalock file. There's no exact model megalock dll.

Was hopi that wouldn't be the case. The reason I did that was becasue TWRP was not seeing my 64gb card so I could do a Nandroid(not enough space on internal).
Guess I have to wait until I can get home to find my old 32gb card so I can then download the ROM again and then flash.

Ended up having to reintsall rom and do a complete wipe because even after dirty flashing, I kept getting an error saying Home had stopped.

[HELP!] GPS not working after updating to Marshmallow!!! - D850

Right after I updated my D850 to MM, my GPS doesn't get a fix on location properly. Sometimes it just does not work and sometimes when it does work it points me the wrong way. I've never had this issue before, the GPS also does not seem to be live too, meaning that it doesn't update constantly. Instead it jumps every 10-15 seconds. Am I the only one with the issue? :crying: :crying:

I can definitely see this being a software problem with marshmallow. Ever since downloading it on my LG G3 D850 it can barley read sim cards anymore, and since D850 (as far as I know) can't downgrade I'm screwed.

If it can barely read SIM cards that's a hardware issue. Software wouldn't cause that. What do you mean you cannot downgrade? Yes you can.. You just follow my guide and use LGUP and flash kitkat.

Lg G3 d850 Marshmallow boot loop.

So I recently updated to Android 6.0 and it worked perfectly. So about 1 month later (today) I get prompted with a message stating there is an update going to install in30 sec. I let it do its thing setting the phone to comeback right when it's booting up(or so I thought) instead it's the boot loop going on over and over. So I remeber the flash tool so I decided to go with that but it didnt work. Is there any fix for the Android 6.0 boot loop on LG g3 d850?

USB debugging is for software that's not required in download mode and doesn't have anything to do with download mode. What was you running before? As custom roms will make it show up unknown. And not sure on a fix for that
