Stuck at bootup

I got my nexus 7 yesterday and straight away unlocked it with adb and flashed cwm and superuser. I've just tried to boot into recovery (turned off, held volume up + down then power, selected recovery) and it's just stuck at the black screen with Google in white and the unlocked logo.
Can't really do a battery bull on these soooo.... any ideas?
Edit: forget it, after about 20 minutes, literally after posting this, it booted back into android like normal <_<

Glad you got it working just a little tip tho cause I did something similar and I wiped data and formatted system to flash a new ROM, then I accidentally pressed reboot so I couldn't get into android or recovery cause as of right now you can manually boot to recovery , solution just use the one click method to root and it will take you directly to recovery the you can mount storage and flash a ROM

HELP! Bricked Nexus 7, cannot boot into boot loader

Hello everyone, I'm new in this forum and have just bricked my Nexus 7 .
I was not very happy with my Nexus 7 with JB version 4.2.1, it lagged and took long time to load apps etc. I used the Nexus 7 toolkit to unlock my bootloader, flash recovery and then tried a few custom roms. I eventually flash the official 4.1.2 firmware from google but the constant notification for firmware update annoyed me and I decided to root and get rid of the firmware update notifications by installing fotakill.apk.
But when I tried to root using the Nexus 7 toolkit, I chose the option to sideload the zip files for rooting automatically. It asked to flash my boot loader to a lower version (3.34, mine was 3.41) and afterwards it rebooted the device and eventually got stuck at a screen with these lines:
now send the package you want to apply
to the device with adb sideload <filename>
after a long time without anything happening, I suspected that things went wrong and pressed the power button for a few seconds and the device turned off. Now I cannot turn it back on, when plugged in it doesn't show the charging battery, also I cannot boot into fastboot mode by holding Volume down + Power button. The screen stays black the whole time.
I even tried to open the back power and pull the battery out and in again and try to turn on the tablet, nothing happens. I remember the battery level was like roughly 90% the last time the tablet was working, so I don't know what went wrong .
Hold power + vol down button about 30 seconds

I tried that but nothing happened .
Press all buttons on the side simultaniously untill fastboot/bootloader mode appears. This should work, no matter if your device is booted or not, or soft bricked or whatever. Then: http://forum.xda-developers.com/showthread.php?t=1907796 .
If it doesn't work however (like after 30-60 seconds), then connect your nexus 7 to your PC. Go to device manager and identify your device. Does it say apx-mode or something like that? Then your device is possibly hard bricked and you might find some answers here: http://forum.xda-developers.com/showthread.php?t=1879228 .
Your should not have used rootkits. Most of these topics appear after people using toolkit. Learn to use fastboot. It's the only program you'll need for the nexus 7. Yes, it's a command line tool but at least it forces you to think before flashing. For example, it was not necessary to downgrade your bootloader. I really don't get why you did that. Also, if you want to run a stable 4.1.2 without the annoying update messages, you can, for example, flash cyanogenmod 10. It's stable, very smooth, and way better than stock.

Thanks I did a search and finally found an answer. I was running fine on my N7 with PACMan and suddenly it got stuck booting up. So I booted into recovery and reflashed the ROM, and wiped dalvik and cache. When I rebooted it went to "Android is upgrading" like usual after wiping dalvik, then it got stuck there. So I rebooted again and nothing. Just a blank screen. Your suggestion of holding all the buttons down for 30-60 seconds awoke my Nexus. I'm going to wipe everything and start over.

Stuck on "Warning Bootloader Unlocked" Screen after OTA

I bought my first phone from Swappa a couple days ago, and figured I would go ahead and by a rooted/unlocked RAZR M and start messing with ROMS.
When I booted the phone, and got connected to my WiFi network it said I had an OTA, so I went ahead and installed it, (now I know that one should avoid OTAs on rooted phones), but now its stuck on the Warning Bootloader Unlocked screen. I do a hard reset (power + volume up/down), it boots, its done, I unlock the screen, it shuts down, repeat. I can't get it unstuck.
This is my first experience with any sort of unlocked or rooted phone, so I have no idea what I'm doing.
Please help

Which option am I supposed to choose (1-6)? I can't boot into it normally, its stuck on the Warning Bootloader Unlocked screen.

You need to be in fastboot, before connecting the phone to the computer and starting the utility. Brandon gave you the key combo to do it.
I got it fixed, and it upgraded to 4.1.2, then went to install Eclipse ROM, the install failed so I hit ++++ back+++++ and then rebooted from the recovery menu, and now it's stuck in the Warning Bootloader Unlocked screen again. Hard reset doesn't work, it reboots back into the Warning screen, and the utility that was posted earlier isn't connecting to recover the device.
What now?

Boot back into fastboot and use the utility again. The utility won't work unless you're in fastboot, and for heaven's sake, make a backup of your stock ROM, before flashing anything new. If you had a saved ROM, this would be easy. After Eclipse failed to install (it has been well documented that a straight install of Eclipse through TWRP or CWM usually won't install), you could have easily gone to the main menu in recovery and clicked "restore" and restored with zero issues.

always make a backup man, safe yourself some time.
I can get it to boot into Fastboot no problem, but when I go to run the script its not recognizing that the phone is connected. The phone says "Connect USB
Data Cable" even when its connected. I'm not sure which side is failing to see the connection, the phone or computer.

30min old Nexus 7 4.3 brick, not rooted! HELP!

I got a new 2012 Nexus 7 back from Asus service today. I logged in, checked android version which was 4.1.2, updated the pre installed Google apps and the 4.3 update appeared. I thought no problem as my old nexus 7 installed 4.3 fine.
I let it update, but near the end of the update, an on-its-back android figure with error appeared! After a few mins it restarted, but it won't boot past the coloured animated x before the user interface loads. I've restarted a few times with no luck.
I found a Google article to boot into recovery (when off, hold volume down and power on, select recovery with volume keys, then when no command shows hold volume up and power), but "wipe data/factory reset", "apply update from ADB" and "wipe cashe" does nothing.
I have not rooted my nexus 7 and I don't intend to (I didn't even root my old one).
Is my 30min old nexus 7 bricked?
What else can I try?
Just unlock it, restore all the stock factory images and then lock it again.

Got a full refund and brought the FHD Nexus 7. Kinda glad I had trouble with the first gen.
FYI, bricked = not powering on or responding at all. A device booting to Fastboot and Recovery is most definitely not bricked.
my nexus 7 1gen stuck on erasing data. i cant get fastboot mode and now cant connect to my pc too,
plz help

[Bricked?] Can't get to bootloader after trying to unlock with NRT

So I have a nexus 10 32gb that I got yesterday that I updated to 4.4.4 and I wanted to root it so I could get some apps that I love to use. Here's what happened:
Everything was going smoothly with nexus root toolkit. I set up adb and all of the drivers. Everything with that was working and I made sure to check nexus 10 with 4.4.4 in the drop down. I press the unlock bootloader button and the device says it's going into bootloader mode, but it just goes to a black screen. Then a message pops up saying I have to factory reset if i'm on 4.4.4, but that never shows up on the tablet, so I just hit OK. Then the device supposedly reboots, but now it's stuck in a bootloop and whenever I hold down the buttons to go into the bootloader the screen will turn black and the device will vibrate once after I hold the buttons for a while, then it tries to reboot again and gets stuck bootlooping. Then I try the factory reset method through the nexus root toolkit, but fastboot fails to see the device since I can't get it into the bootloader! It also doesn't show up as the correct device when it is bootlooping and connected to my computer.
Am I scewed if i can't get to the bootloader? I don't know what went wrong. I just got it yesterday and assumed it would be super easy to root since it's a nexus device. :'(
Any help/ suggestions would be great.
You are correct, nexus devices are super easy to root especially without a toolkit, most rooting issues I've seen on any nexus device has been due to the use of a toolkit so I would advise not to use it.
Currently you need to get into bootloader so you can flash a custom recovery with fastboot and then flash ROM of choice from there
Try adb reboot bootloader while in bootloop but I have a feeling this won't work. So if not try powering on holding volume down, even try with volume up, just keep trying button combos to get it to boot into bootloader.

Try power and both volume buttons at the same time if you haven't already.

I have actually been trying that. I just let it die while it was bootlooping, so hopefully when it gets a little charge I can try to get it to go into the bootloader again. I have a feeling there's a bigger issue than that though.
