Stuck on Google logo boot screen -- Bricked??

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

Brick Scare: Can't Access Recovery From Hardware - Only From Software

So I have this strange issue. I just tried shutting my tablet down so I can reboot to recovery to flash something. (Mind you, I haven't flashed anything in a few days)
So I shutdown and I can't access recovery. It just wont boot. Vol+, Vol- and Power at the same time. I tried going power first, then volume and vice versa but no dice. My volume buttons and power button work perfectly fine while in the ROM.
Now at this point I was like, "Screw it, I'll boot into the ROM" but no.... It wouldn't even turn on. I tried plugging it in and nothing (~70% battery when shutting it off). Then I plugged it into my computer and it showed "Device driver software was not successfully installed" with a device named "QHSUSB_DLOAD".
Quick Google-ing made me think I bricked the device. I ended up just holding on the power button for a good minute and it finally booted into the ROM. I'm still unable to boot into recovery via Power + Volume Buttons... I have to use an app to boot me into it.
Why? What happened / is happening?

I'm not sure with the N7, but with my SGS III that's what happened when it bricked.

Yeah... very strange. I'm able to get into the bootloader without a problem... only through an app.

Can you attempt to reflash your recovery?

Could you double check you are pressing the right buttons based on these instructions:
[Info] Guide to entering safe mode, bootloader, stock recovery
You are NOT supposed to press 3 buttons, Vol+ and Vol- and Power as you described, rather just 2 buttons depending on whether you want recovery or bootloader.

Well now I feel like a total dimwit.
I guess I was so used to my Galaxy Nexus... I did a Google search on how to access the N7 recovery but I guess I glanced over the instructions too quickly.
This thread can be locked, lol.

BTW sorry, I fixed the link.

[Q] LG G2 D802 can't get into download mode

My phone is completely messed up.
i got an update form LG.

I has CWM installed.
i but could and even when try to install new rom it was still in boot loop.
i installed manual via adb commands TWRP.

1 sec after i get few error codes and then black screen without ADB support.
i trierd to get into download mode after reading in forums that only this can help.
but I can't.
I powered down my phone in all possible methods:

Thanks
Ran :good:

sorry was wrong.
try turn phone off, add usb, then press volume up. I think that's it.

Hi
did no work also

I am having the same problem, went to lg service centre, they could not enter download mode as well. I might need to change the circuit board for $321 singapore dollars..

Hi
i think you have to use this fix: http://forum.xda-developers.com/showthread.php?t=2582142

This happened to me,
Try holding the power and volume down hold until lg logo, let go and press and hold the volume down and power again, it should get you in recovery.
It might get you into a screen called "Factory hard reset" Agree using the power button, and it should take you to your recovery, and try flashing a ROM along with the Gapps (if you want, which I did) and then I used a recovery file after booting back into recovery to restore it to my previous state.
Good luck :good:

Shut down phone
From what I got from this, you're having problems shutting down your phone, correct? It keeps booting back up after the screen goes black? If this is the case, hold the power button (and don't let go) until it goes black, reboots itself, then goes black again. Shouldn't take more than 2 seconds after rebooting to shut down. Then, you can do volume up + USB to get into download mode.

Stuck in recover mode and power button not working

Hello everyone
lately i entered to recovery mode through adb but my power button is not working and when i remove the battery and plug it in and turn on the phone trough the charger and the battery it keep booting to recovery mode is there any way to get out of recovery mode without using the power button your help is really appreciated

Doesn't the recovery have a reboot option?
In case, your volume up button might also be stuck. The device can't enter recovery just with the power button.
Either that, or your OS is messed up.

I used adb terminal and enter it by mistake and my volumes button is working but the power button is not

Fix bootloop Galaxy Tab A 10.1 [SM-T510]

Hi, my device is boot-looping forever. I cannot enter recovery (I have TWRP installed). I cannot even switch it off.
What I have tried:
- normal switch off through power button (device is not switching off). It always restarts itself
- reboot to recovery (Power + Vol Up)
- reboot to bootloader (Power + Vol Down)
- force hard reset (Power + Vol Down for 7 seconds, then Power + Volume Up)
None is working.
Can I enter the recovery, maybe issuing some commands from a computer?
Any other option I could try?
Thanks!

No, the PC won't help. The trick is to hold power and vol down and as soon as the screen blanks, switch from VOL down to up, while keeping power button pressed. You have to be quick when switching or it will just bootloop again. And the cable shouldn't be plugged in.

Thanks, this helped. I recovered from the bootloop.

Hi, I'm stuck in bootloop too. The fix above isn't working for me. Could somebody discribe the process a bit differently please? Maybe I'm doing it wrong? What exactly is the time to switch from volume down to up?
My bootloop shows the Samsung logo then a warning about unlocked bootloader with prompt to press power and then the Samsung bootlogo again. Inbetween the screen turns of for a few seconds.

I was able to go to download mode by connecting the tablet to my pc and pressing vol + and - at the same time. Then I installed the nexus rom by Magendanz. Made a factory reset and format data in twrp. Everything is fine now.
