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.

I had several android phones before
all of them had standard recovery which look like this one:
http://www.omappedia.org/images/b/b3/2011-03-22_19-27-25_273-II.jpg
but when I try to enter recovery mode with the GN I only get android lying (link in operation) with red triangle and exclamation mark.
there is no wipe or other options to choose from.
also the only thing I can do in this state is to pull out the battery.
SO...
where is the stock recovery?

It's right before you. You just need to hit a key combo to get past the warning screen. Perhaps the same one you used to get to the recovery.
if you just leave it, it will reboot by itself eventually

There is no combination to enter recovery directly.
I entered fastboot mode
and selected recovery.

I'd go ahead and try either volume down / volume up / or both at the same time to see if u get into the stock recovery once your at the exclamation screen

Yeah, that is pretty much what I meant by my post. there is only 3 keys.
so it's either:
up vol + power
down vol + power
up and down vol + power
I think it is the last one, since I think that is what takes you to fastboot. I don't have my Gnex just yet. so can't check.
I just tried again all the combination
still nothing
Press the middle of the volume rocker after you are in the fastboot menu and the top selection will scroll the boot options including recovery. Hit power when the desired option is displayed.
Thats what I did to get to the red triangle
I found out what the next combo is
first hold power then add volume up
Thank you
Thanks guys
Spent ages messing found ODIN mode and others then one search and up pops the ansa.
Wow lots of weird answers in this thread.....
In recovery, if you see the android with the exclamation point, press the power key and while holding it press volume up. This will reveal the recovery UI.

For the life of me I can't get the Vol Up + Vol Down + Power button combo to bring up any menu options in the recovery mode on my Galaxy Nexus. This is a GSM from the Play store. I'm running stock Jelly Bean setup. I was trying to unlock the bootloader and do the factory image install, but I kept getting a boot cycle. I tried to go into recovery to data wipe, but I couldn't ever get the menu options to come up, just have the Android on his back with the exclamation point. Anyone else see this?

press power and vol down and up and you'll get the menu.

Wait, let's see if you're not confusing things.
To unlock: with the device off, 3bc (3 button combo) power+vol up+vol down. Hold it until you see bootloader screen. Connect the device to pc previously set up with fastboot, and in a command line, type 'fastboot oem unlock'. Accept on the device.
When in recovery (accessable by using volume keys in bootloader screen, also allows to reboot bootloader, start system), press vol up (or vol up+power, can't remember right now) to see stock recovery menus.
Nevermind recovery right now, follow efrant's guide on flashing stock/unlock. Set up fastboot. Don't use toolkits.

Ok my phone is now flashed. But I still can't get anything to show up in stock recovery. I can get to bootloader and volume up to recovery then I get the android on his back with bang. No button combo here brings up any menu options.

Awesome, thanks! This actually works, not sure why the 3 button combo wouldn't get it every once in a while. Is the 3 button combo used for the CDMA VZ version of the phone? I even saw this used in a youtube video!

Nope. It's power and volume up to get into the recovery menu from the recovery screen. Power and volume up and down is to get into the bootloader.
I tried power and volume up. Nothing happened!!!
I flahsed back to stock.... and got bootloop. since I didn't flash data image.
Edit:
Ok got it. press power button first .follow by volume up.
So I messed up...
I flashed the new JB, rooted, and unlocked it(FreeGee) and it was working decently. For some reason (that I can't remember now), I had to go back to ZV7 using LGNPST. When I reupdated to ZVB, I think I forgot to unlock with FreeGee and debloated. (at this point, you're thinking "this guy is a complete idiot") After my next restart, I got the dreaded "security error" bootloop.
I didn't panic yet. I went ahead and tried to downdate to ZV7 again using LGNPST. At 85%, the phone rebooted as normal but after the boot screen, it froze showing the "4GLTE" screen at the end of the animation. I tried waiting it out but no luck.
When I tried downdating again, I'm getting the same boot screen freeze. Worst part is I can't access recovery; the phone just restarts and goes through the boot animation.
So now, I'm panicking. Anyone else encountered this problem and/or can enlighten me please?
Go to recovery and factory reset the phone.

I tried accessing the recovery (Vol up + power?) but it just starts the boot animation. Is there any other way to access it? Also, because I used LGNPST, it should open the stock recovery, right?
Power button 45 seconds
Hold the power button down for about 45 seconds. This will truly turn off the phone.
Access recovery using Vol. Up and Power buttons, then factory reset, and reboot.
You will be good to go.

No luck :crying:
As soon as I hit the two button combo, I get the red LG globe logo pop up for a second.
If I release as soon as I see the logo, it goes to the boot animation
If I continue to hold the buttons (and wait for the the blind menu on the bottom left), the screen remains black and nothing comes on...even after holding the buttons for 45-60 secs.

HOT DIGGGGIITTYYY!
It worked! Thank you so much!
I couldn't get into recovery last night either.
This is the simplest way, methinks (from command prompt with adb.exe in same folder):
adb reboot recovery
I'm trying to up date my parents Nexus 7 to 4.4.2 but it refuses to install.
The device advises that the update is available. It downloads without any issues. The device reboots and starts the install process. It reaches around 20% and displays "ERROR" with the android logo lying flat with an exclamation mark.
The device is brand new and has not been rooted etc. Does anyone know how to fix this? Any help would be appreciated.

When you see the android with exclamation mark hold down the power button and while you are holding the power button down press and release the volume up button. You are now in stock recovery. Use the volume button to highlight "wipe cache partition", press power button to select. Once that is done select reboot. Maybe wiping the cache well have helped. Try the update again. If that doesn't work, you have two choices that I can think of. Try a factory reset or adb sideload the update, for adb sideload you need a computer with adb setup on it. If it was rooted with a custom recovery there would be other options. Good luck!
To get to stock recovery... with the tablet off, hold down the power button and while you continue to hold it down press the volume down button until it boots into the bootloader screen. Use the volume button to select "Recovery mode" then press power button. Now you will see the android with exclamation mark again. Hold down the power button and while you are holding the power button down press and release the volume up button. You are now in stock recovery.

Hi, thanks for replying.
I have tried this to no avail. I do however have further information regarding this error. When I press the power button and up I can see that it says "/system/lib/libchromeview.so" has unexpected contents. Does this mean that the software is not suitable for this particular device.
This all seems very strange as it's a brand new device and I'm getting the software from google directly?

The OTA will check the "System" to see if anything has changed, if it thinks anything has changed then it will fail. The update should absolutely work for your device. If a factory reset doesn't give you the ability to do the update, and I have my doubts, return/exchange it. Don't wait too long! Otherwise you need to use adb and at the very least, flash the system image to fix the problem. I personally can't think of any other options that you have. I don't know for sure but maybe there was an app that changed "/system/lib/libchromeview.so." Maybe the Chrome Browser or Chrome Beta. Try and uninstall the Chrome updates and/or Chrome Beta if it is installed. Settings/Apps/All.

No problem!
There's no need to exchange for what's a relatively simple software fix. If you search the forums, you'll find easy-to-follow instructions for unlocking the bootloader, then flashing the stock recovery and latest ROM.
I no longer trust Google's OTA update process anyway. Flashing the full stock ROM ensures you'll start with a perfectly clean slate.
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!

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.

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
