Are you sure your friend has an original LG G4 and not a knock-off?
Could you post a picture of what he has in backup and restore? Also, while trying to get into recovery mode, could you record a video? I'd like to see what's happening in each of these cases. To me, it sounds like it's not an LG G4 from LG. Could be a knock-off or something like that. It's very strange that those two things wouldn't work... One is independent of the OS he has installed as booting into recovery is very basic, and the other sounds like a customized version of the OS rather than LG's default. But I also have a European model, and I don't know where his is from... Where is it from? It seems strange...

the phone is Origin from LG and bought from CLOVE in UK. And it's already got a FOTA update last week and the rom is a stock one. posted 2 pictures. Now I realized two more things when I double knock on the screen it gets me directly to the home screen and not to the lock screen and only the back button of the home touch screen buttons is working.

These are what I have. All I can say is that the HW is opposite side of mine. Hmmm

Boot it on recovery mode to do a factory reset. To do that. Turn OFF the phone, HOLD Vol- and Power button. When LG logo shows up, Release the power button for 1 second and hold it again. (keep holding VOL-) Keep both held until you see the factory reset option. Use Vol up or down to select Yes or No. Press Power and wait for it to reset.

I tried this at the begining but it didn't work. the last thing that I tried through LG bridge to"restore update error" and after the update when the phone boot up still I had the same mistake and no factory restore. I turned off the phone and tried the recovery mode as you discribed and this time it worked and reset my phone.:good:
Thanks a lot guys for your help.

[Q] How to enter recovery mode using key combination?

I can use "adb reboot recovery" to enter TWRP 2.7 recovery mode, but I want to use key combination, please tell me how to that.
Hold Power + Vol Down > Wait until LG Logo pops up and release from both buttons > quickly hold Power + Vol Up + Vol Down again
It will pop up with some message about reset to factory settings, but it's all a bluff.
Hit Power x3 times to confirm and you'll get to TWRP recovery
Thanks, it works.
actually I enter this factory reset mode before, but i just don't know it a "fake".
so will this erase all data or not?

That will depend on whether you've installed TWRP or not.
If you've still got the original recovery it will wipe it like it says it will, if you've got a custom recovery it will take you to it.
The standard recovery isn't a recovery like you're expecting it to be, if just has a way of resetting things to default without allowing you to do anything extra. OEM don't like giving people options but want a way to reset to defaults that the customer can use before needing to return a faulty unit which might not be faulty. If that makes sense.

From what I can tell, it's not a "bluff". It seems that the stock recovery partition would just automatically do a factory reset, so it warns you before booting the recovery partition. Seeing as you're non-stock, it just boots into TWRP/CWM. It's a valid warning that's simply set up in a weird way.

You don't.
We'll you might be able to but you're going about it the wrong way.
First you need to find the right forum for your device, then you read, followed by more reading.
At some point you've hopefully discovered that you should have done all this reading before you reset your device.
Also before pressing the post button on your next post, read it first to make sure it makes sense.
Thank you very much, I tried other combinations found on some web pages that failed. This one worked!
Issue remains.

I got myself in a pretty bad situation. I have the stock rom. I am trying to get that back using recovery but it's not working. Only factory reset screen. This tablet stopped working in 2015. It cannot write ANY data ANYWHERE. Can't take pics, Can't take screenshots, Can't download apps. Nothing. I really want my tablet back... :/

Install LG software on your computer first. Then with the tablet completely off, hold VolUp and plug the tablet into the computer. That will enter LG download mode. Use the LG software on your PC to install the latest firmware available for your device. From there you can use the guides on this forum to go custom if you so desire.

[SOLVED] How do I boot into stock recovery?

From a full power off, how do I boot into stock recovery? I've tried multiple button configurations and none work.
EDIT:
I called T-Mobile and they said:
1. Power off
2. Press and hold the Vol - and Power button until the LG boot screen appears.
3. Release the Power button ONLY. Do not release the Vol - button.
4. After 1 second, press and hold the power button again. You should see the white recovery screen.
Use the Vol+/- to navigate and Power to select.
This brought up a Factory data reset menu on my H815.
Brings up factory reset on T-mo version H-811
That is the LG factory recovery.
thank you this worked
With a Verizon model, I had to keep holding both Power and Vol - until the recovery screen appeared. If I released and then re-held Power, as described above, it did not work.
When I hold down power and vol down, it boots to an IMEI display screen. It shows a long barcode. Can't get to recovery with the hold, release and hold down again the power and volume down buttons. Frustrating.
I love you so much right now. It boots into what appears to look like a default LG G4 factory reset page. For me, i clicked reset, and then yes, and surprisingly it brought me to where i wanted to go. TWRP Recovery.
THANK YOU!!!

I never clicked "Yes" in the Factory Reset phone option because I thought it would do just that. Instead it took me to TWRP!!

The difference was that you have twrp recovery and he didn't. The question pops for both, but for those that have the original recovery it will do the factory reset.
worked
worked for me, but the first screen is the one where it ask if i want to factory reset, i had to pick YES, then again confirm, and then i was in TWRP

And I get a factory reset as well on my H811, even though TWRP was already installed and working on the recovery partition.
Something else funny going on, the OS seems to kill TWRP after the next one or two boots tho. Maybe I need to set the TWRP option to allow change of the system partition to read/write? (Since apparently it writes something there that prevents the OS from killing the custom recovery after it's been installed)

I've learned a lot with LG phones over the past few weeks.
The biggest thing is.. when you first flash over TWRP, you HAVE to reboot into recovery before you try rebooting the system, or else the bootloader will overwrite the TWRP install and replace it with the factory recovery.img. (You probably already know this.) To make sure it boots into TWRP first, since fastboot doesn't have a "reboot-recovery" command.. I just pull the battery then do the button combination to boot directly into TWRP. Doing this allowed me to say "YES" to the question "Do you want to factory reset the phone".
I don't know how many times I've wiped my phone because of this:
1. flash TWRP.
2. reboots (tries to hold the finger combo but failed - and didn't know it)
3. gets asked question - "do you want to factory reset the phone"
4. I hit YES expecting it to take me to TWRP - but instead it wipes the phone and puts stock recovery back on.
Just do this:
1. flash TWRP.
2. PULL THE BATTERY
3. Use finger combo to boot recovery.
4. When asked "do you want to factory reset the phone" - hit YES
5. TWRP boots in like 5 seconds.
This has worked now for my G4 and my V10 since they both have this issue. The V20 however does not (my current phone) - so hopefully LG is done with this crap!!
Good luck!

What was happening on my H811 was that it was either corrupting the recovery partition afterwards or just invalidating it or something because instead of getting back the stock recovery, I'd get the scary "broken robot" screen when trying to boot into recovery.

The technique I've learned to appreciate (which apparently is a new thing, and is now the suggested method for installing via fastboot according to the twrp.me website) is to load a copy of TWRP into RAM to do the flashing and rebooting. ("fastboot boot [TWRP_IMAGE_NAME]")
I try to avoid battery pulls as much as possible but I have never relied on them on a phone the way I have done over the last week (just had my G4 for about a week now) due to these funky mechanisms that LG has for getting into recovery/bootloader/download mode.

TBH I am fearful of even trying it now. (Especially since I just read about how a nandroid backup done from TWRP doesn't backup anything on the /data partition, either.. )
Which makes me even more appreciative of LineageOS's "advanced reboot" power button menu. :good:
One of the problems in my view with this LG system is that it can be very difficult to reliably press both the power and volume at the same time on this phone due to it's unusual placement of those buttons. Much harder than on a phone with those buttons on opposite sites of the device. Not to mention this silly "press both these, then release one, then 1s later press that one again" stuff.
And due to the way they designed these sequences, which among other things often have no way to easily escape them (can you imagine having this on a phone with a non-removable battery?? ), but worse, have defaults that progress to another state without any user interaction (because of the limitations of this control logic - eg, if you boot to bootloader but can't escape and don't do anything in 2 minutes, the device automatically reboots), I personally have to wonder if this doesn't make a significant contribution to the infamous bootloop issues that lots of people are having with recent LG's like the G4, G5, V20, etc.

[Q] touch goes crazy after test mode

i have tried go back to test mode, more i dont know how to reset to somekind of factory test mode

Factory reset can be achieved by holding down volume + power buttons at the same time.

Enter recovery on 20B?

Hi, I'm having a major problem getting into recovery via the power-on+vol-down key combination on MM (20A/20B) - under no circumstances can I get into recovery from cold boot - I can reboot into TWRP recovery when the phone's booted, but recently I've had a couple of bootloops which never enter the OS and so I'm stuffed - both times all I could do is use LGUP to reflash 20B kdz and then re-root etc etc. I'm assuming under MM the key sequence has changed, or is it because I have an unlocked bootloader the sequence is different? I've owned a G2 and G3 and know the "normal" sequence of hold power+vol-down, wait for the LG logo and release then power+vol-down again, but this doesn't seem to work on a Marshmallow G4 (I've tried 100 times with different wait periods on the release etc)....
Its a real PITA not being able to cold boot into TWRP/recovery so can someone advise what the sequence now is (and PLEASE don't reply to tell me its "hold power+vol-down, wait for the LG logo and release then power+vol-down again"!).
Thanks!
I have the same issue and I had been running into same situation to entirely reflash my phone in order to get it boot again. The key combination never worked for me while on 20B; really frustrating if you run into whatever problems requiring to recover through TWRP and not being able to do so.
key combination working me....
If not
adb reboot recovery
Or if phone rooted.

And it never came to your mind, that maybe the entry to recovery might be different to an LG G3 or G2?
The way to enter recovery is:
Hold Vol- and Power until LG Logo appears
Release ONLY Power button for 1 sec
Then press it again and hold it
Recovery entered
I guess google can save lifes And nerves!!!!
Cheers bro
EDIT: Btw this has nothing to do with Marshmallow, Lollipop etc. It's the usual way to enter recovery on a G4 And I didn't read the OP entirely. It seems like you just had the wrong sequence. This one works for me on Masrhmallow 20B!

Thanks for your heads-up. Unfortunately if i try this combination a screen appears "Factory data reset" asking "No (Exit)" or "Yes".
Now I would assume if I enter "Yes" it would boot into recovery, but I am not sure whether this will completely wipe my phone.
Can anyone confirm that I´m on the right path here?

Hold on. There are 2 options. If you installed recovery properly (I bet you did), indeed, clicking on "yes" will boot you into recovery. If you're a monkey, just like I was, and DIDN'T install recovery properly, yes, it will just wipe your data.
But that's the usual way to hardware-button-boot into recovery
How did you install it? There's an easy way to check if everything is set up correctly. Use this app to boot into your recovery from within android.
If it boots you into recovery then everything is set up straight and you can boot into recovery with hardware buttons a 100% by clicking "yes" and "yes" in the "stock" recovery.
EDIT: I know that's an awkward way, but it's the right 1 Cheers

LG G3 Fall Down and now is in reset loop

Hi
I have LG G3 which fall down and now is in reset loop.
reset and then load android after 1 second reset again and again.
I have data and picture on that.
How can i get backup from data and pictures and how can i change ROM?
BR
Seems like a hardware failure due to the drop, thus why you cannot power it on.
If you have a custom recovery (TWRP) try booting into that (if you're not sure then you probably don't have it), it would be able to get your files off to a PC. Though (again), if it's a hardware failure I doubt it's going to work.
Unfortunatly I get the same issue.
The LG G3 was only working properly when connected to the Power AC/DC.
It was an issue with the batterie (try Amazon with the BAtterie reference not that expensive ~15 Euros).
Cheers

Try boot to safe mode
1. Turn off your LG G3 phone.
2. Now boot the phone.
3. Once seeing the LG logo appears, long press on the VOLUME DOWN key until you see the home screen.
4. Your home screen will have Safe mode in the lower left corner.
