No download mode on stock rom? - G2 Q&A, Help & Troubleshooting

Hey guys,
yesterday I bought a used LG G2. The G2 was rooted with a cloudy ROM (G3 Port). I wanted to bring it back to the Stock ROM an unroot it.
So I made a downgrade with this guide http://forum.xda-developers.com/showthread.php?t=2625044
It works! After that I was on 4.2.2 and after all the OTA Updates I am now on 4.4.2 (D80220f-EUR-XX). Everything works.
My problem is now, that I can't go into the download mode. If I try Power Button and Volume + after a few seconds the red LED glows and no download mode.
What happened? Is there any (other?) way to go into the download mode?
Sorry for my bad english, I am not a native speaker

I tried Power and Vol Up. I tried also only Vol Up. It does not work.

Anyone else?

Something similar happened to me, I was trying to enter to Factory Reset Mode and I had read it was turning on the phone using Volume - and Power Button, then release them and press them again. But it was not working. Then I read that it had changed a little in KK. It was pressing Volume - and Power Button, and when the LG logo appears, release both buttons and press Volume + and Volume -. Maybe it helps.

Unable to get into Recovery

LG G2 D802 Three (H3G) KK 4.4.2
Hi all, I've checked out this forum and also watched a few videos. I've tried the volume down + power until the LG logo appears and then release and re-press them but all that happens is that the phone powers off after the second press after about 10 seconds. The volumes buttons work fine. There's clearly a trick to this but after about 20 attempts, it has be beaten! Any clues to the magic sequence needed?
TIA
EDIT: Yes, I can get into download mode no problem.
when the lg logo appears try releasing power and volume down and then pressing volume up instead

Thanks for the reply.
If I just use volume up after the LG logo, the phone reboots normally. If I do a power + volume up after the LG logo, it just powers off after 10 seconds.
In fact every test shows the phone to behave exactly as if the volume up and down buttons have been disabled during boot up.
Tried a few times again - no recovery. Maybe it's something that has been blocked in the stock KK OTA update?

I think what he meant is when phone powered off, press volume down+power and when you see lg logo press volume up+down don't touch power

Update: I can get into recovery using adb. Maybe H3G have disabled getting into recovery via the hardware buttons only leaving download mode available. Bit of an odd thing to do though.

D'oh! That was about the only combo that I didn't try. Yes - it works. Many thanks to both for the help. Just curious: this alternative key combo I didn't find anywhere; is it something some carriers have done to their phone? (Or did I just not search hard enough? )

lg changed the combination when they started releasing the knock code update, I have no idea why but now it just means some people need to use volume down+power while others have to use volume up+down it just creates more trouble for us(people who help others) because if people don't mention whether they have knock code update or not we just have to guess what update they are on

I have the same problem, no download mode on my G2 (European version, stock kitkat without root, bought it a week ago).
Just to be safe, the way I tried to launch it into download mode was:
1. Powering off the device.
2. Holding the volume up button.
3. Plugging in the USB cable (while still holding the volume up button)
The LG logo shows up for a while, after which the charging animation shows ups...

Your phone must be turned off
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
that is the known method for G2 unless you flashed a custom boot-loader or changed the keys to enter download mode or recovery etc .... now try to enter a hard reset mode but don't apply it or all your data will be gone i say again don't approve it it is power+Vol down
if it works i think the keys combination are still in default then try to enter download mode again
if it didn't work return the mobile to be fixed or changed
Thanks for your reply!
The method you described is the same as the one I used, unfortunately it doesn't seem to work. I can't seem to get it to boot into recovery either...
I believe this reddit post describes my problem:
https://www.reddit.com/r/lgg2/comments/2n4gqa/unrooted_lg_g2_on_stock_android_442_kitkat_will/
The OP's conclusion is:
So I rooted and installed AutoRec and that got me Download Mode. Afterwards I used LG Flash Tool to flash the stock KDZ file onto my device to unroot it and to see if Download Mode is still enabled which it was not.
I believe this is LG's way of preventing users from upgrading to unofficial/unreleased firmware.

I managed to fix the issue by performing an emergency recovery using LG software. It must have been caused by one of the OTA updates.

[Q] Stuck at boot after Nandroid restore

Hi
I installed FluffyRom (which is based on Simple Rom) on my D802 and everything was ok.
I was not happy with the ROM so I did a Nandroid restore of my previous install which was BlissRom
After reboot I can see the LG logo, which then flickers a bit and fades away and then black screen.
If I connect to my Windows PC I can see the internal storage. If I long press the power button, something vibrates and if I tap the screen I can shut it down so I assume that the rom is running but I do not get the visuals.
I would like to have it working again, what can I do as i don't have an idea... the only thing I found out is that the baseband has been changed by the Simple Rom install ...
BlissPop need JB baseband:

Have you tried either of the following:
Download Mode
Power off your G2.
Hold Volume Up and plug your G2 into PC via USB cable, keep holding Volume Up until your G2 displays "Download Mode".
If in Download Mode follow this tutorial.
Recovery Mode
Power off your G2.
There's 2 possible options to access Recovery depending on your current Bootloader.
JellyBean Bootloader
Hold Power+Volume Down, when the LG Logo appears let go of Power+Volume Down and again hold Power+Volume Down.
KitKat Bootloader
Hold Power+Volume Down, when the LG Logo appears let go of Power+Volume Down and hold Volume Up+Volume Down.
Yes, to power off your phone, long press power button for 15sec.
Then enter recovery with vol down + power like @d00lz say.
(Hold Power+Volume Down, when the LG Logo appears relaise Power+Volume Down and press again Power+Volume Down.)

Can't boot into recovery mode

I tried to update my LG G2 D802 from CM12.1 to 13 using the following steps:
1. reboot into twrp (2.8.7.3)
2. full wipe (all but internal storage)
3. installed bootstack-d802-CAF-signed.zip
4. installed CM13
5. reboot system
so far it worked fine, so I went back into recovery mode, installed the open_gapps-arm-6.0-stock-20151203.zip. After reboot, the phone keep throwing error messages "google service is closed" and keep repeating. I thought it may be an error in the gapps so I went into recovery again and tried to install another gapp version. I did a full-wipe again, but then I accidently did a system reboot. Now the phone is stuck after showing the LG logo and won't start properly. I try to go back into recovery mode:
1. turn off the phone
2. press power + volume down until the logo shows
3. release and repress the both button, which should bring me into recovery mode, but it didnt work. tried it numerous times, but always the same, if I release and press the both button after LG logo, the phone would just restart after few seconds...
can someone help me? Since the phone doesn't start, I can't install anything. Is there another way to get into recovery mode? Or can someone explain to me what I broke?
Don't press and release the volume down and power button at the lg logo. Just hold it until it goes into recovery.
If you can't get in, try to TOT back to stock. I would recommend you stick with rooted stock before you hard brick it(if you haven't done so already). Not only is cm buggy ass hell on the g2 but MM will be even more so since it's so new. Good luck.

+1 to this method, i have been using this when I was not able to get into recovery easily. My issue is unrealted to yours though.
I had a similar issue trying to enter Recovery on my phone. I've tried a lot both methods, so I turned off the device, waited something like 5 minutes, then tried the vol up + vol down method and it worked. I don't know why, but that's not the first time I have to wait a bit longer to try the key combination in order to enter Recovery. Just in case you can't turn off you phone completly, hold power button till phone turns off, keep holding it, wait for the LG logo to show up, when the screen goes off, release the button. Good luck

It's not working for me. I got excited for a minute since others had luck with it, but it was a no-go for me. I know this is an older thread but....
It seems like being rooted, having TWRP and CM13 and Flashify, between all those, something should freakin' work, besides goofy hardware button combos. :crying:
