Question in the subject. I'm just confused as to what download mode really is, and how one would use it. I know you can flash things via fastboot in fastboot mode, but what exactly is download mode and what can you do with it?

Download mode is for you to collect RAM dump with memory debug apps.
I believe download mode would use whatever tool LG uses to flash firmware. As long as you have a working bootloader there shouldn't be any need for it on a Nexus device.
Oh alright. On my old phone, download mode was used to upgrade or restore stock firmware (i.e. ODIN or Heimdall) since we didn't have any fastboot mode.

Yeah, I was confused as well. Used to have it on S II. Bootloader/Fastboot is the term here.
Fastboot is the main method of flashing, you send the files to the phone with fastboot, then the bootloader will write them to the relevantly specified partition.
Download mode allows you to connect via lgtool (the equivalent of Odin) as in you dump the files into an app. Then the app writes them to offsets in the nand.
Fastboot is much easier and safer to use.
The only reason you should ever need to know anything about download mode is if you have broken the bootloader (which I'm not going to say how to do because there will be some idiot who will try it)

Use fastboot commands to flash stock image....
Boot into fastboot and then connect n4 to your PC...run adb and type fastboot devices....
It will give you n4 serial no. And then flash stock image(Google how to flash stock image using fastboot commands)

Hi I've done stupid thing for myself:
i tried flashing 4.4.2 stock rom. coming from 4.2 (i think) did the usual format data/cache. then rebooted then it loops on google logo. I can go to recovery mode.
So are you rooted? Custom recovery? Looking to flash stock? What bootloader do you have? Ota flash? Fastboot flash?

I still cant get fastboot up. ive used minimal fastboot and/or SDK Package. also changed the path for environmental variables.
So more info will help, usually the more info you give the faster your issues can be fixed
Are you in bootloader mode? I take it your using windows, what version? Has adb or fastboot ever worked before? When you type
fastboot devices
You get nothing? Can you post a screen shot of terminal, of environmental variables? Are all proper drivers installed? Does anything pop up in device manager when tablet is plugged into USB while in fastboot, recovery or os? Are you using factory USB cable?

sorry about that.
im in fastboot mode with power and both volumes pressed. i can also go into recovery mode TWRP v2.5.0.0
also rooted and yes windows 7 64 bit. recovery mode or fastboot mode . it doesnt recognized my nexus.
not sure if i have the right drivers. i cant find any drivers to download for nexus 10
Does anything pop up in device manager when tablet is plugged into USB while in fastboot, recovery or os? - No
and yes im using nexus 10 OEM cable.
i really appreciate the time to help me out with this issue.
Its no problem,
The SDK should have the drivers you need, or you can install the universal drivers made by koush or a number of others as well. Just Google search or a search xda for terms like
Nexus 10 drivers
Universal android drivers
Android naked drivers
You will find many that will work just fine for you
If in cmd you type
fastboot
And you see a list of commands than you know you have it installed
When you type
fastboot devices
And you see your serial number your good, if just a blank line then you need to get tab to communicate, this is most often a driver issue. If you can't find ones that work let me know and I'll link some to you, also you may need to uninstall old drivers and than manually install new ones, windows doesn't always do the best job of picking the correct drivers

finally found the driver that works and now
i get R32D2009DAT
Im assuming thats serial number whats the next step
Google search
Android factory images
Here you will download the correct one, latest manta for the nexus 10
Then extract the contents of the zip
Now if you want to keep custom recovery that's a good idea but if you want KitKat you will need stock or at least update to the newest twrp (as you current one won't flash kk)
So if you want twrp then google search
Twrp recovery manta
And then find the latest image, 2.6.x?
Oh and its a good idea to check md5sum for both the zip from android source and for the recovery image, both will tell you what it should be in download screen and there are many ways to check, just google search
Windows md5
There is both official and none official, I personally use Linux command line and can't recall the name of the program I use for windows off hand
Also note that the following commands will wipe all from tablet, it is good to do this but if there is anything real important back it up first
Now from fastboot, enter these commands
fastboot erase system -w
fastboot erase boot
fastboot erase recovery
Now find the bootloader image you extracted from the android .zip
fastboot flash bootloader nameofbootloader.img
Now if you want stock find the system image
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot flash cache cache.img
fastboot flash boot boot.img
Now find the twrp recovery image
fastboot flash recovery nameofrecovery.img
Here you can boot to new recovery and install superuser or just boot to pure stock, or if you want one of the many great custom ROMs you can boot to recovery and use adb sideload to flash one

re install the adb drivers boot the phone into recovery , toolkit will detect your phone
Power off the phone, hold the vol+ and vol- button, press and hold the power button. This will take you into fastboot. Connect the USB cable and install the naked USB drivers.
Well, I ****ed up my lg g2 today, I wanted to modify the build.prop but now I ca't use my phone because error messages keep popping up. I can only boot into fastboot mode. When I try to boot in to downloadmode it redirects me emediatly to fastboot mode.
I tried this but I can't flash the laf file somehow. When I type: fastboot flash laf laf.img (or laf.bin becasue thats the actual files extension) in says that it cannot load laf.
Please help me, this is the second time my g2 broke down ....... Im beginning to break down I think =(

if you have download mod you can install the kdz in off line mode and it rebuilds the prop file.

try to push the power off button, when the boot logo comes push long immediately the power off button again, may be it helps to turn off the phone.

Make sure fastboot and laf.bin or img are in the same folder. Or at least put laf somewhere, let's say c:\ so you can run fastboot flash laf c:\laf.img
the laf and recovery were in the same folder as my fastboot and adb. But the extension of the laf is .bin and not .img Does that matter? because I was able to flash the recovery whn I typed: fastboot flash recovery recovery.img
But When I tried to flash the laf with: fastboot flash laf laf.img - fastboot flash laf laf.bin. Both the commands didn't work.
