How to boot into stock recovery

I'm trying to clear my caches because my battery is doing some funny stuff every since I got the tablet. Just constantly being used up, even over night it drops 25% when I'm not doing anything. I've only downloaded a few apps but it says "Android OS" is what's taking 50% of the battery.
So I get into Recovery by turning off the device, holding power + Vol. down and then I select Recovery mode.
But all I get is an image of the Android with it's belly open and it says "No command."
How do I get to where I can run everything?
Please help!
Thanks!

Is your bootloader unlocked and have you rooted the device yet? The only way I know how to clear the caches through recovery is by doing that first and installing a custom recovery like twrp. If you aren't rooted yet and don't want to root the device I would suggest doing a factory reset first and see if that helps. To do a factory reset go to settings --> backup & reset.

You can do a factory reset like the previous poster mentioned.
If you want to get the stock recovery menu from the android fallen screen, press volUp.

Here is your answer if you cannot get in to the os. The commands will not show up unless you do a two button combo. You can get in to stock recovery by doing the following.
When powered off
Hold power+vol down
When bootloader screen comes up
Use volume down to select recovery and then hit the power button
It will then go in to recovery but only show an android with exclamation point.
From here to see command you have to press power + the middle of the volume button (There is a middle button here) Saw the button in the teardown.
From here you can do a factory reset of the device also.

Yeah this didn't work. I know I got into recovery once without being rooted, but that was on a different device.
I did a factory reset so we'll see if that helps. But it isn't looking like it....
No apps downloaded, only on wifi, brightness is all the way down, turned off location services and the "Android OS" is still taking the battery. It's at 96% after an hour and a half of literally not using it at all...

When you get to the screen with the android and !, press and hold the power button and then press the vol up. No other combination will work. You can not press the buttons at the same time.

There is writeup on how to enter recovery here:
[Info] Guide to entering safe mode, bootloader, stock recovery

[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... :/

I'm probably not the best person to help, however if you put a new post up with more details on what you have access too, the community will be able to help out.

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]I might have messed up somewhere Stock Recovery

So I downloaded the Stock Recovery from Mr Hofs Collection of Stock Recovery thread in General Section.
I flashed stock recovery, all went well. I attach picture of command prompt to show.
After I flashed it though and went to recovery it just gave me a black screen with a little phone in the middle, in the middle of the little phone was a red triangle with an upside exclamation mark. It was stuck like that for the better part of half an hour(pressed volume down with power, held power alone for minutes on end) nothing. No writing on it nothing.
Luckly as I was busy starting this thread now it just rebooted on its own and went back into the system. Is it totally fixed now or will it give me problems when I go into recovery? Should I go into recovery again?
How do I check if stock recovery is fine now or if there are any problems? I don't want it to hang and/or brick now.
Please if I made a mistake somewhere, tell me what I did wrong for future reference, I don't think I did anything wrong with commands
You can see at bottom of command prompt to, I even tried fastboot devices / adb devices to see if it picks anything up because I get the sound the computer makes when it's connected to USB so the computer at least picked up something.
Should I sell the phone now? lol

Boot again into recovery using the method you described. Once you see the android with red triangle image press and hold the volume up key and then press the power button while keeping the up button pressed. You'll enter the stock recovery.
This is the normal way of booting into stock recovery. You are fine!

I tried going back into recovery, got to the screen with the triangle and and pressed volume up and power button like you said. Instead of then taking me into stock recovery, it just vibrates and then reboots the phone.

hmm...i am running TWRP on GPE so i am not able to test this directly. Let's try one more time, but this time follow these steps:
- go back to recovery and wait for the red triangle screen
- wait for 5 - 10 seconds (don't think this is necessary, but try it anyways)
- this time press both volume up and down keys, and while holding them down press the power button
hopefully this will work. Otherwise i can try on a friends phone in the morning and give you the right combo.

Same thing, just vibrates and then reboots

What are you hoping for? You have stock recovery installed now. You seem to have discovered why there are custom ones.

With no recovery options, is that right though? It doesn't show me anything written on the screen and when I press "up volume and power" this should take you to some options, it gives nothing, it just reboots.
Not right then? Or will it still work fine just as it is now for OTAs?
P.S I have tried all methods given by umsheikh, I downloaded quickboot to try it, I did an adb reboot recovery to see if I can go through there, did it manually, shut off, wait a bit, turn back on go to recovery press power, wait 10secs press up and power, nothing, all of them just reboots the phone. It's bugging me lol
If you say it's right though and there is no need for me to actually see the options that it gives and I'll still receive my OTAs etc then fine, I'll leave it then, but I don't think it's right, is it?

Getting into the options is fiddly, but it sounds right. Try fastboot erase cache

Thank you, clearing cache worked, I see options now in recovery :good:

Delete update

When i try to boot into recovery, my phone tries to install the update and it won't go into recovery. is there any way to delete the update file ?

bump

Do you have an MOFD_UPDATE file on the root of your phone or SD card?
If it's an OTA, it should delete after the update runs.

wipe cache

Hold power button and press volume up key a few times or until you get to recovery menu. I got stuck like this for a little while too until I realised I'd skipped a step to get to recovery...

Oh, I was thinking that it actually started an update, then errored out or actually ran an update.
Yeah if it's just the dead Android icon, that's normal. That's what happens when you boot into stock recovery on these phones for some reason.
As stated above this post, just hold the power button for a second, then press the Vol-Up key. Once you get the timing down, it'll be really easy to do, but you might have to try a few times to get it to actually kick into recovery.
Don't hold the power for 5 seconds or it will reboot. Make sure you let go of the power button after you press the Vol-Up key.
This will happen every time you boot into recovery when you have stock recovery.

It actaully starts an update. thats the problem. i get the fastboot menu, select recovery and it trys to install update and fails

It's not actually updating. That's just what it does.
When the dead android shows up, hold power for a second and press Vol-Up while still holding the power button. Then release power when the recovery menu shows up.

[Q] I am at the bootloader and my power button won't let me select

I took my phone in for a cracked screen and when I got it home I found out the volume up was not working. So I booted into recovery thinking I could check in recovery to see if it was a software or hardware issue, but the volume up did not work there. So I rebooted and now my GPE edition rom is stuck at the spinning dots. When I go back to the bootloader I cannot select recovery. My volume down button make the selection go up, my volume up button does not work and for some reason even though I can reboot with the power button, I cannot select with it. Is there any other tricks to wipe and reinstall?
ADB does not return a device list.

I had the exact same problem, but opposite. Vol down didn't work. Bootloader problems were the same.
Your issue is that you vol up is stuck.
The way i fixed it was to pull off the volume rocker and put it back on my own. I DO NOT suggest you do this.
When you took it for repairs, the reassembled it incorrectly. Take it back and have them fix it.
