My N7 ran out of power and shut off. I immediately put it on the charger and it turned on for a minute (without me turning it on) and then powered off again. After that it booted to the White "Google" screen and continues to reboot into this screen.
I can get into fastboot (holding power and the volume down) where I have options to Power off, restart bootloader, recovery mode (which shows me the red triangle and says "no command"), or start.
I am not rooted and the bootloader is still locked.
I'm good at following directions and have tried what I thought were solutions but nothing seems to be working... or perhaps I am just retarded (no offense to people who are actually retarded) I think I have installed the correct drivers but I still can't get the cmd prompt screen to show my device when I type adb devices
How do I fix this? I don't want to send it back and deal with that hassle!
Thanks in advance and I apologize up front for what is probably a simple fix but I couldn't find any other posts with a solution that has worked for me.

In boot loader you use fast boot commands. Type "fastboot devices". If listed type "fastboot reboot". If its still stuck in loop try and taking back cover off and disconnecting battery for a few seconds, reassemble and power on.

Thanks. The battery pull didn't work however your tip on typing fastboot instead of adb worked and it recognized my device. Consequently I was able to flash the stock image and start over with setup and etc.. which sucks but it's better than sending it back in and all that mess.
Thanks!
I tried unrooting my phone, but it got stuck in a boot loop.
When I try to enter to recovery mode to factory reset I get an android lying on its back with a red triangle.
I've tried a bunch of combinations of buttons, but the phone just turns off if I hold power + volume up.
In cmd prompt on the PC type: adb reboot recovery. That should work.

that is the stock recovery. what you want to do is flash the factory img via the bootloader/fastboot.
You have the buttons right, but you don't really hold the two down. It's a bit tricky but once you figure out the exact way to do it, it's easy.
Press and hold the power button then immediately after press volume up. Then let go. The menu will appear.

Your device should be called Nexus 4 and not Samsung. Install the drivers from here http://forum.xda-developers.com/showthread.php?t=1996051, after that connect the phone through usb, look in device manager and delete the device. Reconnect again and choose manualy wich drivers to install and choose the driver you just installed. Now your device is called Nexus 4.
your stock recovery over wrote your custom recovery and that made the little android with the triangle come up. all you have to do is reflash a custom recovery using fastboot.
go to zedomax channel at www.nexus4root.com and he gives you video instructions using the cmd on your computer
Try this:
Go into bootloader and recovery
You will see the android with the red triangle
hold power and press volume up (tricky part)
wipe cache
If this doesnt work try doing a factory reset instead
I tried rooting my A500 this morning. I've done it before, but this time it didn't seem to go as planned. I was trying to root with http://http://forum.xda-developers.com/showthread.php?t=1546593. It didn't work, told me to reboot, and now I'm stuck with a black screen, the power button light is flashing like it normally does while it's powered on, and holding the power button down won't power it down. Help...?

Install adb.
Open up a command line (or *nix terminal emulator)
run:
adb devices
If you get a response from the device, you may have a chance. If not, there's always the fun way using APX mode.

Hey guys,
So I got my G2 today and rooted it using the recommended root thread(IOroot10). It completed successfully and installed SU onto my device. It didn't actually ask for any permissions when i opened it and when I attempted to update the binaries it fails because I never get the toast about granting permission. So I factory reset and tried again. It didn't work the second time either. I thought maybe it's because I didn't take the latest OTA, so I factory reset one more time, took the OTA, and am now stuck in boot. I can't get to any recovery or download mode.
The phone boots the LG logo then gives me a boot loader secure check real fast that it fails. After that it goes to a black screen and there's nothing I can do.
When I plug the phone in and let it get to the black screen, it creates a ton of virtual USB drives (16 to be exact). The first one contains a write protected folder named image which contains the files modem.bxx, mlserver.bxx, mc_b2.bxx, adsp.bxx, cmnlib.bxx, dxhdcp2.bxx, isdbtm,.bxx,
mba.bxx, playread.bxx, tqs.bxx, wcnss.bxx, widevine.bxx, where the xx in .bxx is replaced with sequences of 00 up to 26 in some cases. The rest of the drives it creates are empty.
Any sign of a recovery is completely gone, and I have no idea where it went
This is what appears in the top left of the screen when the LG splash pops up for a split second and goes black

Things I've tried:
+Completely power off:
-Hold Vol Up and plug phone in (doesn't work)
-Factory Hard Reset (doesn't work)
-Hold Vol Up + Down and plug phone in (doesn't work)
-Power on, press Vol Up at vibrate (doesn't work)
+The phone never makes it to a point where I can ADB into it. I get the splash screen(with error) and straight to the black screen.
+Completely drain the battery and plug it back in to charge up. I end up with the same issue.
+Fastboot will not recognize the device, so flashing the recovery that way isn't an option.
-Could be a driver issue, but I think the phone just never makes it to a point where I can use fastboot.

Perhaps I'm missing something in that thread, but none of it applies to me.
The link to the other thread for if you can't get into download mode only talks about having TWRP installed on the device, which I don't.
And the rest of it is if you have ADB access, which I don't as well.

To get into download mode the G2 needs to be connected to the computer and upon turning on immediately press volume up. Compared to other devices, it's a weird way to do and may take a couple of tries to successfully boot into.

I'm still having no luck. I've read nearly 4 different ways to enter download mode for the vzw version and none of them have worked yet.
Holding the power button itself just restarts the device and it heads right back into the black screen. If I continue to hold the power button after it restarts, I get the LG splash again and then it shuts off.
It seems like the stock recovery is completely gone, but I don't understand why I wouldn't be able to get into download mode because of that.

The device itself will not turn off without me holding the power+up button for around ten seconds. Holding the power button itself just restarts the device and it heads right back into the black screen.

Power off your G2, press Volume Up & Down key and then plug in the usb cable (enter to a download mode)

I have tried every button combination there is and still no luck It's really frustrating.
Try keeping USB plugged into both computer and phone. Hold power button down, as soon as u feel the haptic feedback from the reboot hold down the vol+ button.

truckroot, that does indeed work, I actually messed with my build.prop file today and it soft bricked my phone. It would turn on you'd see the LG logo and a black screen, man I was livid. So later I was going to to have it replaced under warranty, I called Verizon and what not and he told me to press this button combo and I got straight into CWM, holy crap that was quite an easy fix for me. Here is the key combo under "Alternate Method"

Yeah, I tried modifying an apk and got caught in a bootloop prior to button combo on recovery being available, so I thought I was screwed. Finally managed to get into download mode as I described and all was well.

Hi guys,
i have a G2 D802 rooted with TWRP recovery. My brother did accidentily the OTA update. After that my LG had a bootloop TRWP.
Nothing was working, then suddenly it went black . No Screen, no battery light while charging, no recog from computer, no adb, nothing when i plug it onto the Computer. i searched tons of forums and threads , i used every method, but my phone does not do anything
Several threads are for phones with working ADB or anything working , mine isn't working at all .
What can i do ? i can't bring it to the LG shop because they told me it was rooted and rooted phones have no guarantee in our country.
Please folks does anybody had have the same problem ??

turn your phone completely off: unplug it from the usb and hold down the power button for like 20sec. the phone should not be turning on or doing anything. then press and hold the power plus volume down. as soon as the lg logo pops up, let go of those 2 buttons and immediately press and hold power + volume down again. this should being up an all white screen with black letters. now press the power button 3 times til you get to "factory resetting". this should boot you into twrp. from there you can do whatever you want. this time do not take the OTA. hehe.
the drivers for your phone will be on lg's g2 site. make sure you've installed those with your phone unplugged from usb. if you have a previous driver installation, uninstall that. the lg drivers have the adb driver inside of it. also make sure you are using the most up to date adb.exe. if not then it may not be able to communicate with your phone. you can get that from android's sdk.

The fact that you see anything, is a good thing. Let battery completely die, and then plug into USB while booting to download mode. I had VERY similar issue and that's worked for me, then flashed to stock.

With your phone on, and in recovery (twrp), plug it into your computer.
Open device manager.
Look for a disabled/uninstalled (marked with yellow) device that corresponds to tour device (in my case all it said was D800).
Choose properties/driver/update driver.
From here, you have to choose all the manual options ("let me choose the driver to install"), not automatic, .
Finally Windows should show you a list of device drivers compatible with your device.
choose the LGE (or androidnet) Single Sooner ADB ...
Let it install
Test your ADB interface (ADB Devices).

Sounds identical to the problem I had. It's like a REAL slow bootloop. If you catch it just right, can you get it to factory reset? And then from there, it just does the same thing?
Ooops.
I saw bootloop twrp.
I missed the black screen.
What do you get when you hold the power button for longer than 15 seconds (force shutdown), then power it back on (hold power for a few seconds, then release)?
If you have a fully non-booting device, warranty it, of course blame it on the update.

turn the phone completely off. unplug it from the usb/charger. while the phone is off, hold down volume up then plug in the usb/charger. you should automatically see download mode pop up. if that happens then you can return back to stock by googling howto's. if not then you will have to take it in.
no devices when you plug it into computer in that state?
Hopefully none of that text at the top of the screen mentions root or modified system.
