You need to have the phone in Emergency Mode to be able to flash roms, hold down answer key + send key + power to get a green led light, then plug it in and start the program

Ok. Tnx ..
You can remove the battery IF YOU WERE FLASHING BASEBAND ONLY
then put battery back and press vol up + back + power and phone will go in emergency mode
disable all lg modems in device manager, then flash baseband again and it will work
I remove battery ~10 times, and phone always automatticly go in emergency mode when i back up battery, but device is not recognize by tool like a LGMDP-v1.5, lg studio kdz updater on computer.
1. remove battery
2. put battery back
3. press power button+ volume up button + back button together
4. keep buttons pressed and phone will go in emergency mode
5. now lgmdp will recognize device
@TheAndroidGeek

Disable modem drivers (LG) in Device manager!
In Device Manager is disabled only LGE Virtual Modem because he is only there. But error is still there in lgmdp.
Hooo ...
I back phone in life with this tutorial: http://forum.xda-developers.com/showthread.php?t=1197111
Thanks to xzet2 for that tutorial.
Now, i installed this ROM: http://forum.xda-developers.com/showthread.php?t=1818219
But i dont have service again (no signal - baseband is unknown). With android 2.2.2. is all ok (have service, baseband v10e is show and all work ok) but i want ics.
I trie to flash baseband to P500-v20G but lgmdp dont see phone when this ics rom installed. When installed android 2.2.2 lgmdp see phone.
In Device manager LGE Virtual Modem is disabled.
What to do?
Does ok to install ROM with android 2.2.2 and then flash baseband on v20g version and then install ics, or what?
And again hoooo ...
I start phone in emergency mode, run lgmdp and flash baseband. That all work 10 seconds, and wala ... now i have new baseband and ics rom.
Thanks!

Lost Access To Download Mode After Kies3 Initialization

I was in a bootloop because of a failed ROM flash, however i could enter Download Mode and i used Kies3 to initialize my device and that brought me back to a working system (COI9) But now I have a serious issue, I don't have a download mode?
When rebooting, holding the combination does nothing, just continues me into Windows (Volcume Down + Power + Home) Recovery is accessible, but its the stock Samsung recovery, the option to 'Reboot into bootloader' also doesnt work, my S6 just starts up normally.
Is there a solution for this? I need Root and Xposed back, what should I do?
If you can enter Recovery mode, you must be able to enter Download mode. Usually it is the other way round and people cannot enter Recovery mode. See if your buttons are working properly. Press all buttons (Home, Power and Vol UP + Vol DOWN) then when the screen goes black, try pressing the combination for Download mode.
I 'did' try everything, it was as if the boot loader access was blocked, the ONLY way I could get in was through the "ADB Reboot Download" command, and still then it wasn't the "full" download mode I was use to, it had no info.
I genuinely lost access to it, wasnt able to get in what so ever

You mean it goes into Download mode when you try through ADB but it has no writing, is the background still blue and still says something like "downloading target" or whatever it says in Download mode. If it like that, then try see if odin recognises it.
Yes I have succeeded now, its back to working, but in still baffled as to why and how it happened

I think I bricked my Samsung Galaxy S6 SM-G920I

Ok, so I tried to root my phone using odin and cf auto but at the end of the process when my phone got rebooted I was stuck on the logo screen for ages and this small red text showed at the top saying something like recovery is not seandroid enforcing. So after searching through solutions I tried formatting the phone but when I tried to go into recovery mode it just rebooted back to the logo screen. So I then tried to reinstall the firmware but after doing this Odin said failed and then my phone got rebooted and is now stuck on the message "An error has ccured while updating the device software. Use the Emergency recovery function in the Smart Switch PC software." But Samsung Kies and Smart Switch says my device is not supported and when I try to go into recovery or download mode the phone just turns of and goes back to the error screen. Can anyone please help me. This is a new phone and my parents would kill me if they found out I screwed it up already.

Put your phone in download mode and use odin to flash ROM. It will work.
Good luck
1) smartswitch or kies wont work at all because you already tripped your knox
2) recovery is not seandroid enforcing <- this text shows you have custom recovery installed.
3) you possibly didnt turned knox off. settings>lock screen and security > find my mobile> there will be an option to switch it off
now solution
1st of all you havent bricked it! its soft bricked and not hard bricked(hard brick wont even turn on)
what you can do is let the battery drain off totally charge it and try to put it in download mode > odin > flash stock rom first(important step).
from there try to turn it on if it does you great. and dont use cf auto root if you are not familiar with it download some other roms which are way better than stock touchwiz,pre rooted and way better than it(like the note5 rom for s6 by arter).
by the way keycombinations >
downloadmode = vol down+home+power to switch off download mode vol down+ power only
recoverymode= vol up+home+ power
if you can put it in download mode follow my steps and hopefully you can,just keep trying

My phone wont go into download mode. When I press the button combination, the phone reboots and goes back into the screen saying the software error again. And the first time I tried to flash stock the phone is how the error message came up.

Ok so I let my phone completely drain of charge, then the second I put it on charge, the phone goes to the software error screen. Download mode just reboots phone into the error screen and recovery mode doesn't seem to do anything. Ill see if Odin recognizes the phone though
Ahm probably you missed something that could help you resolve your issue in much less time.
1. Press Vol Down + Power Button for 5 seconds until it reboots. After the screen is off then quickly switch to Vol down + Home + Power button to access download mode.
It is the key combination to safemode but it your case, it will just force restart your phone. No need to drain your battery.
2. Maybe most of the newbies always missed this part before doing anything to their phone. Backup (either on smart switch or Nandroid*best option)
3. You need to have proper samsung usb drivers installed and check in odin if your phone was recognized.
The only thing I see from your first post is that the firmware installation (odin) was interrupted. Please let it finished installing before doing anything in ur phone. Check faulty usb ports/usb cables to ensure your pc/laptop works well with ur s6.
Let us know how if u still encounter any issues.

do as the guy above said in 1st step thats a key step to put it in download mode
Thank you guys
The phone is all good now. It turns out that the software error screen was also the download mode. So I flashed the stock rom and everything is fine now. Thanks for the help.

Even though knox is tripped you can use smartswitch.
I know this because I have done it.
I rooted my phone, installed custom kernel, etc.
I then broke the screen, and since it was a hardware issue, I got it covered by my phone provider. (I am in Aus, we have different warranty laws compared to the USA.)
But I had to return it to stock. So I used Smartswitch to do so, even with knox tripped.

LG G3 bricked. KERNEL CRASH, No download mode

-----------------------------------------------------------------------------------------------------------------
DemiGod Crash Handler : Kernel Crash! :
Press key to choose Dload Mode/Reboot
1)Volume Up: Dload Mode.
2) Volume Down: Reboot.
If you choose Dload Mode,
Please do following action.
1)Dload Mode. Please connect USB
2) Get the ram dump image using QCT's Memory Debug App
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000000b
------------------------------------------------------------------------------------------------------------
So I had my cellphone on charge, I take it off, turn it on again, text a friend, he replies back, i text him again. And then voila, this screen shows up.
I first take the battery out, again and again, turn it on each time, ends up in this mode. I press the volume down to enter recovery, it does, asks for a factory reset, i select yes, reboots and ends up in the kernel crash mode again, with a long error message.
I come across a fix that suggests flashing the stock rom using LF Flash tool using the tot method. I install the LG drivers and the computer detects the cellphone as an LGE AndroidNet USB device. I proceed, press the start button, but it always FAILS, with a MODEL VERIFICATION ERROR showing up. I have an AT&T LG G3, so I have the correct dll.
I also tried to enter the download mode but failed. The computer does not recognize the device at all. If, on the KERNEL CRASH screen, however, I press the volume up key, the LED light gets stuck, and it says *entering Dload mode*, and if the USB Is connected to my computer, it detects it as an LGE ANDROIDNET USB DEVICE. If however I try entering it using the regular method, the computer doesn't recognize it.
I'm stuck and do not know what to do. Any help would be appreciated. I'm desperate fellas.

Unable to boot, enter flash mode or enable USB debugging after 'succesful' flash

I use this forums a lot for info but in this case i can't find any leads of whee to go with this, so wondering if someone can chip in some ideas?
I flashed a ROM via flashtool but wasn't happy with it, so i thought i'd just go back to stock and so used flash tool AKA emma to flash one of the options given there.
First attempt to flash it said "flash failed" or something like that and had the "flashing failed, connect to computer" note in the phone when booting it. (I'm sort of making up the terms, not that much into the tech ). Anyway, i tried flashing the same FW again and this time it went through really quick being 'completed' in a few seconds.
Now when i try to boot it gets stuck in the 'Sony' logo. Can go into Fastboot but no Flash Mode (nothing happens using the vol down key), and USB debugging seems to be off now as well.
Emma only works in Flashmode so can't do anything with that. Flashtool doesn't offer anything useful in Fastboot and Xperia Companion recognises the phone when in Fastboot but asks that i unlock the screen and enter MTP...
Any help of where i can go with this?
Thanks
P.s. While keeping buttons pressed randomly it went once into flash mode, but trying to flash a ROM with flashtool it got stuck at "reding device data" and i haven't been able to enter the mode again. Is there an alternative key press combination that i stumbled on by chance? I think i just kept vol up and power held for a while and let go at a random number of phone vibrations
Just tried: Flashed twrp via fastboot and then rebooted into recovery. Same thing. It still opens to Sony splash screen and stays there
Ok, i'm kind of talking to myself here, but mild success and something that might help someone.
Managed to get back in flash mode. Don't know if it's a fluke, unique to this phone, or how it's actually meant to work, but the sequence is:
From the freezed up splash screen, and the USB connected, press and keep pressed power+vol up (hard restart/shutdown)
You get a single vibration, if you let go here it restarts. Keep pressing
You get a triple vibration, if you let go here it shuts down. Keep pressing
You get a single vibration, if you let go here it starts in fastboot. Keep pressing
You get a second single vibration, if you let go here it starts in flash mode.
Possibly a fluke but don't want to have to try again!
Anyway, i managed to flash the last working firmware and it's all good, yet this is the unwanted one. So issue is i still need to downgrade the phone to 7.1.1
