unknown key functions - G3 Q&A, Help & Troubleshooting

i have an lg g3 f400l korean model
while trying to go into recovery i pressed both the volume up and down then the power
i got into a screen to my problem in korean
what i did notice that there were 3 options
can anyone tell me to which screen i entered and what are the options?
i did go into recovery by pressing the volume down and power, does anyone know EXACTLY at what point the keys must be released and at what point EXACTLY they must be pressed.
it seems like a trial and error until you get into the recovery, it took quite a while can anyone be more specific
thanks
please no jokes or snotty remarks or guys telling me they have a d85CADILLAC and they get into recovery just by staring at the phone or doing a spok memory touch

Download Mode?

I am think about trying some different ROMs on my phone and I wanted to be sure I could get into Download Mode before I tried any Flashing. Can someone point me to directions how to find out if I can get into this Mode before I try any thing else. I have AT&T Captivate if that matters.
Thanks

i think its pressing the Volume up and down when you power it on, you could try google tho
You do it by holding down the volume up and down keys while the phone is off and plugged into your computer after the download screen comes up you can release the buttons , thats how I did it for odin after I bricked my phone. I also just tested it.
Everything I have read and works for me personally, hold both volume buttons then plug in the usb cable with odin already running on your computer. Also, you will need to know how to boot into recovery. If your phone has 3 button recovery, hold both volume buttons, then press and hold the power button while still holding the volume buttons. Hold all 3 buttons until you see the at&t screen the second time and release all the buttons and you will enter recovery mode.
Download Mode
Hello,
Can anyone here please help me determin the method used to activate Download Mode for the LG VS750 (Fathom)?
All I can find over at gsmhosting is for the older units.
Also, still looking for a solution for cooking a ROM for this unit.
Thanks to everyone.

LG-F400K Steps to boot into recovery

Everyone knows the general steps to boot the general LG G3 into recovery, but at the very least the F400K variant is different.
1: Power + Volume up until LG logo appears
2: Release both and immediately press and hold Volume up + Volume down
I purchased my phone used and already rooted with recovery installed so maybe something was changed with mine but I don't think so as I have seen a lot of people complaining about this
Edit: As stated by itsbighead below, you can use a program called flashify as well. Thanks itsbighead!
Anyway, hope it helps someone!

Why not just boot to recovery using flashify?
Its so much easier
Some people just like the old fashioned way

I had a similar issue but was able to get into recovery mode and restore a backup.
Can you get to recovery like this
Power Down the LG G4
When Off, Press and Hold the Volume Down and Power Buttons at the Same Time
Continue Holding These Two Buttons Until You See the LG Logo
When You See the LG Logo, Let Go of the Volume Down and Power Buttons for 1 Second
After 1 Second has Passed, Immediately Start Holding the Power and Volume Down Buttons Again
Continue Holding These Two Buttons Until You Boot Up into the LG G4 Recovery Mode

i told you nothing work i cant go in recovery mode with this option . and hard reset doesnt work too ... im blocked
Hi I'm sorry if you've already said you can't get into recovery mode or anything but when i bricked my g4 i used the lg flash tool to flash h815 10c stock and then instead of flashing the latest twrp (the blue themed one) i flashed the one before it which is 2.8.6.1 and it worked perfectly so if you manage to get into recovery or fastboot then try and flash that version of twrp instead , good luck buddy...

How did you "brick" (it's not) it? Kill switch is an anti theft feature, usually triggered remotely by the user.

This button combo you posted is wrong any way...you only release power for 1 sec and continue holding vol down and the re press power
I cut and pasted those instructions from another site. They held me back from fixing my phone for hours until I discovered the method you have mentioned. I haven't seen any site that tells us to do it like you said, I just was trying different ways and then hey presto!! it worked.

One click Root failure - stuck at LG logo. Can someone please help me what to do?

Hi
I'd be really really grateful if all of you clearly (more) knowledgeable (than I) could help me.
My phone is a D855 (32gb/3gb) international model which was running on stock v5.0.
I ran v1.3 of the one click root method. and completed the whole process (or so I thought ). However, after the process said it had completed, I removed the usb cable and now find that I am stuck at the LG Logo.
Pulling the battery makes no difference. Once reinserted and power back on, the LED on the top left blinks but no boot.
I have tried to enter download mode (by removing the battery, holding the volume up button and inserting the usb cable) but again, no joy.
Can anyone please tell me what I need to do recover the situation.
Many many thanks
Update: I managed to get into recovery by turning off the phone completely and then pressing and hold Power and Volume Down. When the LG logo appeared, release. After a split second, then pressing volume down and volume up. At the white screen asking you to reset, I pressed Yes two times using Volume buttons. Saw the screen that said erasing data but still stuck at the LG logo.
Can anyone help please?
Update 2: managed to get into download mode by powering down (took the battery out) then holding the volume up button and inserting the usb cable.
What do I need to do next?
hello, you need either the lg mobile suite software or lg flash tool 2014 and a kdz
I would go for lg mobile suite - it will offer an upgrade or select it manually
also -- see the guide from hyelton in g3 general (getting back to stock)

Question Recovery mode say no command.

Hi guys, I have a TMobile REVVL V+ 5G and I had it away for 2 months. I thought I reset it before I switched to my new phone and I want to go back to it because I miss the yuge screen.
If you're still reading, you probably know I'm here cause I forgot the code. When I boot into recovery it says no command and I've literally done the reboot like 57 or 58 times.
Please help. I'm a newb at this I only know recovery mode because I got locked out of it once already.
No worries, we've all been there with you. This is what I can verify works: Once your phone reads "No command" just press volume down and power button at the same time, and hold them just long enough to tap the volume up button. You can probably release all three at the same time, but I recommend letting go of the volume up button, then releasing the other two. So to be clear, you're just basically tapping volume up while briefly holding down the volume down and power buttons together.
