hard reset - G2 Q&A, Help & Troubleshooting

hi guys, i just installed unbranded UK 20d to my handset, the phone boots up but when android loads i get lots of errors and the handset is unusable.. so for the last hour i have been trying to hard reset my handset.. this is the method i am using:
1 power off device,
wait 7 seconds
press vol down and power button together
... as soon as lg logo appears release power button then press and hold the power button again.
how ever i have done this 50 times and it does not work any idea what im doing wrong?
LG G2 802

In 20d reset button combination changed to once device powered off:
-Hold volume down+power button
-Once LG logo appears there are two combinations to try:
--hold volume up+power button
or
--hold volume up+down+power button

It's cuz you're not doing it correctly.
Yes, you're supposed to depress "vol down & power" but once you see LG logo, let go of both buttons and then immediately hold down only the "power" button.
After a few secs, a white factory reset screen will appear. Ignore the warning and press power button. I know, its kinda scary at first, but then phone will load into recovery.
Does'nt function
I have an lg G2 f320k model, and I press two buttons (power and vol-), and depress both when I see lg logo and press only power button again, and after few seconds, lg restarts again (reset). Any convination with power button pressed do the same: reset! please, someone can help F320k owners?

Fully power off phone and try the following one should work:
1)with phone powered off hold volume down+power and when lg logo pops up let go and quickly press again
2)with phone powered off hold volume down+power and when lg logo pops up let go and hold volume down+up don't touch power
This will lead to factory reset menu press power button 2 or three times and phone will boot into custom recovery

according to many reports the hard reset button combination was removed in 20d
Also people say(and I've tried it..works)
1. hold down power + volume down untill the lg logo appears(now usually you would let the buttons go and press them again untill the factory reset menu appears but... look 2.)
2. let the buttons go and pres volume up and volume down and hold them..

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

Can not able to enter recovery mod

all the instruction are same.
1. press and hold the power button + volume down button at the same time.
2. when see the lg logo release them.
3. then push them again and hold (or hold only volume down button)
4. then I will enter in the recovery mod on lg g 2
but unfortunately this instruction did not working for my lg g2!
how will i do now?
i have put wrong knock code and then i need to put the backup code but unfortunately i have forgotten the code. there is no internet connection on the phone so Google recovery doesn't working. what can i do now?
still i am not able to enter recovery mod, so i am not able to hard reset
The key combinations are different for every bootloader.
If you are rooted and you installed custom recovery menu then you have JB bootloader and the key combination specified by you should work.
But if you are on stock firmware (with stock recovery menu) then you have KK bootloader and the key combination is different:

With the Kitkat update the process has changed:
Power OFF by holding long the power button till black screen!
Press and hold power and volume down until you see the LG logo then release and press and hold the volume up and volume down buttons until reset screen appears.

Do the instructions you said, but don't release volume, just release power button at LG logo and then press it again right away.
