I unlocked the bootloader and flashed a custom recovery. I then rebooted the device. Now it is stuck at the bootloader (white Google logo on black background) and I can't get it to do anything else. I've rebooted it a bunch of times including with the vol + and vol - buttons held down to no avail. I've also let the battery run out and then tried to boot it up again and the same thing happens. adb nor fastboot see the device and it doesn't show up in the logs on my machine (Mint 13) as coming online at any time.
Most of the times I reboot it with the power switch it reboots to the Google logo even without me letting go of the power button. Sometimes I can get it to fully power off but I haven't figured out what combination of vol keys and reboot does that.
Anyone have any ideas what could be wrong? Any help would be much appreciated!
You are not bricked if you can still get into the bootloader.
Download the factory image from here, and flash it with fastboot. If you don't know how to do that, read this thread.
I wish I could get fastboot to see it then I could definitively flash that img.
I can't get into the bootloader and can't get fastboot or adb to see it. It's stuck at the Google logo now and when i hold the power key it reboots back to the Google logo with the unlock logo at the bottom.
Thanks for the help
You've tried holding volume down+power for 10+ seconds? That should power off the device, then hold both vol up+down down and power up
Ya I've tried to hold vol + and power for 10+ seconds and it reboots back to the Google logo even if I don't off the power key. Same happens with all the other combinations of keys being held with the power button. I can't get it to turn off now unless I let the battery die
Press and hold power till screen goes black. Then quickly press power+volume down and HOLD.

Tried that and still stuck at the Google logo. I have to go to work for a couple hours and then will hack on it when I'm back. Hope I don't have to deal with Googles rma process seeing how disorganized the rest of that company is

No luck with any button combos but the vol + and power actually turned it off. All out of ideas over here. I'm thinking it really is bricked
I'm in the same spot. I can get it into recovery occasionally but once there it locks up after trying to flash or clear the cache.
I'm wondering if a contributing issue is CMR v6.0.0.6? I updated it from 6.0.0.4 that was running fine. But no fastboot or adb so that is doubtful.
This is frustrating and not a great start with this N7.
thank you

this worked. you have to be fast. as soon as screen goes black release power button then quickly, very quickly repress along with vol up and down.
You will still be able to get into the bootloader! Force kill the tablet by holding the power button for ages. Then hold volume up and volume down and the power button together, which will boot to fastboot.
It looks like a CWM bug as I feared. Anyone in the same boat try here - http://forum.xda-developers.com/showthread.php?t=1782932
Nothing has worked and I've literally tried everything that those three buttons can do. Thanks again for all the help guys. Had a great time trying to resurrect it but guess it's time for it to go back home
Just as I suspected. Google puts out buggy junk once again.
I just wanted to report a similarly event. I have a rooted, unlocked Nexus 7, with TWRP recovery. I have previously rebooted without issue. Tonight I booted into bootloader mode to check something and the hit power button to choose start. I got stuck on the boot logo. After finding this thread, I started with the simplest combination and held power button until screen went dark, then added volume down and once again in bootloader. This time choosing start led to a regular system boot. It's as if the device froze and needed a hard reboot.

I was attempting to boot into recovery and kept getting the 'Google' logo (I am unlocked/rooted with twrp recovery). I wasn't aware that one had to be plugged in via usb in order to *not* hang....
Any way around this?
Once I plugged it in and attempted to boot into recovery it worked fine.
I had a similar issue after using the Nexus Root Toolkit to flash to nakasi 4.2 with CWM recovery - just got stuck on the nexus boot screen, flashing in a loop for over 15 minutes.
I ended up powering down the device, holding power for about 5-10 seconds - then QUICKLY holding both the power and volume up+down keys, it then went into the fastboot screen.
After it was there, plugged it into my PC.
Now, this should work for you - assuming you have all the fastboot/usb driver stuff installed.
I extracted the contents of nakasi-jop40c-factory-6aabb391.tgz into the same directory as the fastboot.exe provided by WugFresh with his Nexus Root Toolkit (google search or xda search for this if you dont have it, i dont think i can post links due to my low postcount) - typical filepath: C:\Program Files (x86)\WugFresh Development\data
By the files in there, I mean drilling down inside the tgz to where the image files were inside so that files like bootloader-grouper-4.13.img, image-nakasi-jop40c.zip etc were extracted into the directory and sitting alongside the fastboot.exe - NOT in a subfolder.
Once its all here, running flash-all.bat (this is provided by google in the nakasi-jop40c-factory-6aabb391.tgz) from the command line or by double clicking on it from explorer should kick off the process. After about 2-3 minutes, it was complete, and my Nexus then booted up within about 3 minutes after that.
Also worth noting, device remained unlocked, but I lost root/root binary

Ive tried the volume down and volume and power but it wont work.... Any suggestions?
You are sure your phone is off and you:
Hold down the volume up and down with your left thumb and make sure there is a click feeling from both buttons and use your right hand to click on the power button?
I'm having the exact same problem. Have tried about 25 times to boot into recovery. Just does not work.
Pull the battery after every failed attempt took me about 2-3 tries. Before you do anything shut off phone pull battery then attempt to boot into recovery.
Yes, I'm doing that. The samsung screen comes up and if I release the buttons it does the normal boot up. If I keep holding the buttons the black screen with "vibrant" keeps coming on and off.
So far I discovered that it works perfectly if you hold the power button until after the Vibrant logo appears and then release the power button while still holding the both volume buttons. If you release the power button before the logo appears it will FAIL.
Only after the logo dissapears you can release the volume buttons.
In other words:
1-Press and hold both Volume buttons
2-Press and hold Power button
3-After Vibrant logo appears release Power button
4-Wait until Vibrant logo dissapears and then release Volume bottons
5-You should now be in recovery
Pito
Wow, I followed your directions step by step and still no luck! I wait till I the Vibrant logo to dissapear to release the volume buttons but it just boots up like normal. Thanks anyways! Is there another way of rooting my phone?
What I do as well is hold until the first logo dissapears and as soon as the second one appears release buttons. Then its in recovery.
Ive tried everything you all have said so far and I still cant get my phone into recovery mode. I was able to do it on my wife's vibrant but not on mine. Any suggestions?
Try getting quick boot from the market. It had an option to reboot into recovery. If your problem is just getting the button push right (i had real trouble with it at first) then this should work.

I was trying to do the 4.2.2 upgrade via CWM 10.1 Everything seemed to be working ok but that the radio was working and could not connect with AT&T. Tried to go back to 4.1.2 with Nesux Root Toolkit. Now it will just sit there at the Google screen. I can't get into the bootloader at all. When I use fasttboot devices there is not list. Looking in device manager nothing is there. I've d/l'ed and re-installed the windows (7) drivers, re-installed Java as well as the SDK.
The only way I can get it to shut off is to hold all three buttons down. Not really sure where to go from here. I'd be happy to just get it back to stock.
UPDATE: I've not been about to get into it no matter what I've tried. I've held down VOL+DN Power for over 10 min. Nothing. VOL+UP gives me a black screen. I've tried different usb cable and different ports. Now, having it plugged into the computer and doing VOL+DN I hear it make a sound after about 30 seconds going up like da-TA than right back down like TA-da.
Not really sure what else to do at this point. I have no problem with opening it up at this point.
I've re-installed the win 7 drivers, system still will not see the N7. Should I just throw myself on the mercy of Google and send it in for repair/replace? What will they do and what will it end up costing me? I would just buy a new one, but I keep hearing that the second Gen is coming out in just a month...

Hi, aklesh3...
The Google Logo (white text on a black background, with an unlocked padlock symbol if unlocked) IS the bootloader.. as is the white battery charging animation whilst charging.
You're just not in FASTBOOT mode....
From a fully powered down state... press and hold VOL DOWN, whist holding press the POWER button. Your device should now boot into the bootloader in FASTBOOT mode.
If you can't get shut the device down (eg. it's wedged/bootlooping), press AND hold both VOL DOWN and the POWER button for a good 30 seconds or more... the device should boot into the bootloader in FASTBOOT mode.
From here...
Code:
fastboot devices
...should yield a serial number indicating you have a FASTBOOT connection. You should now be free to run whatever FASTBOOT commands you like.

Sorry if this post is redundant, but the methods I've seen haven't worked, so I can't be alone. Here is how to boot into TWRP if your phone is boot looping/soft bricked. (info pulled from here, of all places.)
1. Make sure phone is completely powered down.
2. Press and hold the Volume down button and the Power button.
3. When the LG logo is displayed release the Power button only then immediately press and hold the Power button again.
4. Release both buttons when the Factory Hard Reset screen displays.
5. Press the power button three times, like it says. Even though it says it will delete everything, it won't (I can confirm that if you are at least on v2.6.3.2).
6. After a "factory reset processing" appears, you should get the TWRP flash screen, and you are good to go.
Hope this helps someone besides currently frustrated me.
I LOVE YOU! I honestly didn't think this would work but it does and i'm so happy.
just about to make a thread asking how to do this. Glad I searched. way to make you jump through hoops tho.
thanks for this. for me the phone didnt even have to be completely powered off.
i wa sin a sleep of death so i held down power and vol down until lg logo appeared let go and then pressed power again. pressed power 3 more times and it booted into recovery

Hello,
I unfortunately dropped my VS980, cracked the screen, and the digitizer only works on the bottom portion of the screen. I have a new screen coming, which should fix this issue, however I would like to get my data off my phone (pics), but I can't as I have a password (draw a line/shape kind) and without being able to enter this in, it will not connect to my PC as mass storage.
I was hoping to be able to boot into recovery with hardware buttons and get my data that way, not sure if that is possible either, but at least try it. This I found to work to get me to the factory hard reset screen, but I am skeptical to push the power button and have it wipe my data!
I am open to other options to get to my data if anyone has any, including android device manager which is something I have thought of, but not sure if I can reset the security to nothing, or maybe as the bottom portion of my digitizer seems to work, I can enter in a space or a period for a password and enter that in.
Looking for any guidance!
Thanks!
Got it!
Redid the password with android device manager, which got me in, but I didn't even need to do that as I had the brainwave to plug a mouse in with a usb adapter. Works flawlessly, got my data, now just waiting for replacement screen!
Strange Problem
I am using F-320K[G2], Cloudy G3 Rom, when I hit boot into recovery it does bring me to TWRP but hardware buttons doesn't work. It just restarts the phone.
Vol down+Power till LG logo up, release and press and hold again and after few secs it restartsand came back to LG screen. If I continue to held it it just repeat restating.

steps to enter recovery that worked for my Sprint LG G2 on ZVC firmware.
1) hold power and volume down button till you see LG logo -- quickly release these buttons and
2) immediately hold power and volume up buttons to enter into factory reset menu.
Then 3 presses of power key to confirm wipe and enter TWRP recovery. :good:
I was going mad trying to enter recovery for an hour. It appears like different models/software versions have different key combinations for entering recovery mode.
My phone was stuck at lg logo screen and i didnt have nandroid backup of the phone. so couldn't try the TOT restore method too as i waned my phone data.
Another way to get to Custom Recovery

The way that let me get into custom recovery is different.
I hold 'vol up+power+vol down' to start from turned off state and keep holding it[Don't leave just keep holding the 3 buttons]. It doesn't show factory reset screen, it get me into TWRP[Custom Rom] directly. I heard 3 buttons gets u in safe mode IDK but I got into proper working TWRP.

I have a F320S.
Hold Volume up and press the Power Button,when comes Lg Logo release the Power Button and start the TWRP
if anybody's looking for the information in this thread like i was, and the posted method doesn't work (it did not for me):
1. Power off
2. Hold volume down and power
3a. release both at logo AND press BOTH at logo right after releasing
4a. Enter recovery
You should enter recovery, but if not...
3b. Keep the buttons pressed (your phone might continue into the start animation, but if you keep the buttons press it will return)
4b. The first logo will appear. Release both and press BOTH
5. Enter recovery

Just wanted to contribute here in case anyone else had tried everything listed in this thread and still was unable to boot into TWRP.
I'm on Sprint, stock, rooted ZVE, and I have TWRP 2.7.
1. Power off phone, wait a few seconds to make sure phone is completely off.
2. Hold power and volume down.
3. As soon as LG logo appears, KEEP holding down power... BUT release volume down and SWITCH to holding volume up.
4. After a few seconds, screen appears saying "Recovery mode" and TWRP opens up after that.
I went to factory reset my completely stock and never rooted Nexus 10. It rebooted in to recovery and started "Erasing". It did this for a few hours. If I power it down, it will power back up and go right back to "Erasing" and never erase. If I hold power and volume up on this Erasing screen, I can see "Erasing /data", but it never shows any other status. I cannot boot in to recovery, it will only go to the Erasing screen - I never get the recovery menu. I can boot in to fastboot, but I cannot get the fastboot cli program to recognize the device. I've tried installing drivers for it multiple ways with no success. I figure if I can get in to fastboot I should be able to fix this device, but I'm stuck. Can anyone help?

I know the Nexus 10 takes longer to do stuff like that than other devices but I have never had it stuck on erasing for hours. If you hold down the power button long enough, will it reboot? If you can time it right, you should be able to hold the Power + Volume up + Volume down and hopefully get into the recovery. I think it has to be all three buttons. Not just Volume up. At least that takes me to the bootloader screen.

If I hold in power, it will reboot. It does not stay powered down. And when it comes up, it goes right in to "Erasing" again. I thought volume down as Fastboot and Up was Recovery (or maybe the other way around). I will try holding in both volume up/down at the same time instead. I might have tried it in my rage when this happened, but can't remember, so will try it for sure when I charge it back up again (it eventually stops because the battery just dies).

I've always held all three buttons with my Nexus devices and it takes me to the bootloader. You could be right about volume down being Fastboot and Up being Recovery but I'm not 100% sure. There should be a way of getting out of that though. If you just did a factory reset, I don't think it would have messed with recovery or anything.

From https://source.android.com/source/running.html#booting-into-fastboot-mode
Booting into fastboot mode
During a cold boot, the following key combinations can be used to boot into fastboot mode, which is a mode in the bootloader that can be used to flash the devices:
manta Press and hold both Volume Up and Volume Down, then press and hold Power
Hopefully, this thread is still followed....
So, about 6mos ago, my Nexus 10 stopped working and I couldn't get it back working...eventually moved onto a new tablet, which now I hate....
Anyway, I figured I'd head back to my N10 because I loved it. However, one of the reasons I left it was because it was stuck in bootloop and I was pretty sure it was bricked.
The bad news, I have followed MANY, if not ALL, of the suggestions on getting it back, I just cannot get it to boot. The good news, fastboot connects with the tablet. So, some specifics:
The tablet WILL boot into fastboot and I can send commands and the tablet is unlocked (also, I believe someone said they had issues because they had an older version of ADB and Fastboot. I'm pretty sure I downloaded the 'most current' version 1.4.3). So, with that, I was able to do the fastboot erase functions, such as cache, userdata, system, etc... and then also load the bootloader (mantafm01) and also send the stock .zip file (image-mantaray-....) and the tablet appears to load everything fine. Thumbs up, right? However, when it reboots it stops at the 'erasing' android bot and will not pass that. I left the tablet in that state for a few minutes all the way up to 3 days...no success.
I also tried the above using Wugfresh only to have the same thing occur. So, basically, I am stuck at 'erasing' and I don't know what to do. I feel confident that the tablet has the ability to be brought back to life, I just cannot figure out how/why all of the attempts lead to the same issue.
What I can also tell you is that while fastboot 'sees' the tablet, the tablet does not appear as a device in "My Computer" like it normally did when connecting via USB. I am using the original USB cable and have tried on multiple computers, all to no avail. I've downloaded/installed the drivers, as instructed on many links. Also, while I can get to the 'Recovery Mode' by pressing Power, Volume Up, Volume Down, if I choose "Recovery Mode" on the tablet, it reboots and goes to the 'erasing' screen. I have tried flashing TWRP on the tablet using fastboot as well. And, sometimes, not all the time, the TWRP blue/black screen appears but it will not progress past that screen (i.e., it doesn't go into recovery).
So, if you can, please help. I believe I have followed all of the instructions, but I have to be missing something or not following something correctly. I'm stoked that it looks like it's only soft-bricked, I just can't get it un-bricked.
Thanks in advance!
Hello everybody,
I hope somebody can help me to save my N7 (2012).
I installed TWRP without problems and after that I tried to flash a custom rom - which, for some reasons, didn't work.
After reboot my Nexus is stuck at Google logo with an opened lock at bottom...
I can't get to fastboot because when I power on while pushing VOL - button it just get stuck at the same logo screen.
If I keep power button pressed for about 10s, it shuts down but after a few seconds it boots again just to get stuck again at the logo screen...
The only way to shut it down completely is to keep VOL+ button pressed while pressing the power button.
My Windows 7 computer won't recognize the N7 at all anymore, but when I shut it down completely (Power & VOL+), windows says "Unknown device".
Is my Nexus still to be saved or I can throw it away?
Thank you in advance for each advice.

Hi, Conrad-007...
This is very strange - your Nexus 7 is clearly 'bootable' (sort of), with a functioning bootloader, ie., it's not hardbricked... or you wouldn't be seeing the Google logo.
In the distant past, back when I used to experiment with custom kernels on my Nexus 7, it sometimes required the POWER BUTTON+VOL DOWN buttons be pressed and held down for a good 30 seconds or more, to generate the necessary 'interrupt', and force the device into the bootloader.
My first instinct, is to suggest you may possibly have a problem with your VOL DOWN button, and maybe it's stuck somehow or not making contact.
It also occurred to me, that you might be able to access the bootloader with...
Code:
adb reboot bootloader
...or possibly...
Code:
adb reboot fastboot
...and even...
Code:
adb reboot recovery
But unfortunately, I'm pretty sure you need to be running fully booted Android or booted into a custom recovery (eg., TWRP) before you can issue ADB commands. I haven't tinkered around in this area of Android for a couple of years now, so my memory of the specifics is a little hazy.
Anyhow, here's a fairly comprehensive listing of Nexus 7 button presses/interrupts, which maybe of some use...

Anyway, just some thoughts that might give you some clues/ideas, that may resolve your problem.
Good luck, and I hope you find something that works.

Thanks Ged for the detailed answer.
Unfortunately it seems that my Nexus is not booting complete (not finishing the booting sequence due to corrupted bootloader?) and so I cannot send to it any adb or fastboot command...
I read in the meantime that holding the VOL up button while powering up the Nexus, it will bring it in the APX mode (whatever this mean) and indeed, my computer recognize it as "APX" device.
I hope at least that this is a good sign and a first step to bring my Nexus back to life... but I have no idea what is the APX mode and what can I do in this mode to attempt to save my device...
Do you (or somebody else) have (has) an advice or tutorial for me concerning this?
Regards,
Conrad
Hi Conrad.
I'm in exactly the same situation (I've mistakenly posted a duplicate thread here https://forum.xda-developers.com/nexus-7/general/bricked-tilapia-t4005149). Let's continue here. So:
1. I spent 4 hours trying all possible button press combinations, including VERY long presses. I didn't notice any APX device or Uknown device connected to Windows. I might have missed it, you gave me hope. I will check again.
2. APX mode enables low level access to the chipset via nVidia tool nvflash. You probably came accross these threads here on xda:

I haven't so far, as I was not aware of the visibilty of the tablet in Windows. I will check again.
Well, I must have been blind not to have seen all the posts here on xda and everywhere else. I went through the threads and now I know:
1. I can see the tablet in APX mode in Windows. Possibly I could correctly set up the driver.
2. This would be totally useless, since I hadn't backed up necessary blob.
I have a new paperweight
