Okay so I seem to have run into a little problem I was planning on updating cleanrom up to 1.2.5 but was on cwm. I had managed to switch over successfully to twrp 2.2.0. I went ahead and used goo manager to download the updated zip of 2.2.1 and tried flashing it thru twrp. Now I am stuck in google bootloop and cant get into recovery or more importantly bootloader. I have been trying last 30mins to hold power and both volume buttons but it either keeps rebooting back to the google screen or not doing anything at all just have to repress to to turn it off but it will turn back on automatically. I tried hooking it up to my usb and labtop but it looks like it wont even recognize it. I just fully charged it so I am good for now just a little worried cant get out of this mess.
I ran into a problem like that with clockwork recovery it kept on rebooting in recovery but I could still go into download mode I was at work away from my computer so I had no choice but to keep trying that three button magic until it finally restored a backup I had on my external card.just keep on trying to pull the battery then try to go into recovery. You might 've gotten a bad download

problem is I cant get into recovery. or the green screen to get to bootloader. It just completely stuck in a bootloop on the google screen mocking me... I am really contemplating opening it up and taking out battery but is that a good idea? Or is there anything else I can do?
so I pulled off the back cover but really dont want o disconnect the battery might mess something up but I cannot get the device to shut off.
disconnecting the battery does nothing it shuts it off and keeps it off but when I connect it to the charger the battery symbol pops up for a second and then goes completely blank. I went ahead and tried again to boot into bootloader pressing power vol up + down and all combinations of power vol -, power vol +
power turbo press vol +/- but no luck still in google screen.
If you're in a bootloop you need to connect your Nexus 7 to a computer. Then you will be able to access recovery via the Power button and volume buttons.
is it going to make a difference that everytime i try to reboot it just the black google screen? I have tried it connected to the wall charger and connected usb to the labtop but nothing.

It's supposed to do that when you're trying to go to recovery from bootloader without the USB cable plugged into a computer, may need to have the drivers installed on said computer. It's an issue with the nexus 7 bootloader and every one of them does it. What your experiencing is perfectly normal if you tried to go to recovery from bootloader with the bolume buttons and then got the google screen bootloop.
If it doesn't work when you plug it in and try, then try unplugging it, manually rebooting with it plugged in first, or vice versa
Update: I can get on Team Viewer and remotely reboot you into recovery through the PC if you want, or at least give it my best shot.
ok so i disconnected battery and have the device off. I should then try connecting it to the pc and try booting up holding down all buttons?

Have you installed the right drivers on the computer you're using, for ADB and the device drivers, when you unlocked and rooted?
Answer to your question is yes try that. But I wouldn't be disconnecting and reconnecting it, I can't recommend that and then learn tomorrow that static zapped something important.
yea I am getting nothing by connecting to pc. I have all the drivers adb and fastboot installed when I rooted and unlocked couple weeks back but it looks like device is not being recognized or read at all by the pc.
connecting to the pc holding the volume + button gets it recognized for a second and tries to install a driver apx but unsuccessfully.
I am not making any progress whatsoever kinda sucks starting the weekend like this. I have gone thru some bad stuff with my atrix but nothing like this were I cant even access my bootloader boot into recovery or even fastboot. Should I try and get it to just stay off and see if overnight it works its own magic? Hate going to sleep witht his on my mind but I think with a clear mind in the morning something good will happen.
I can get it to stay off by holding both vol+ and vol- but trying to turn it off with just the power button just keeps it turning back on/off...
so I slepted on it thru the night let the tablet rest but went back this morning and I still cant get into bootloader or recovery. Is there anything I can do?
Has anyone else had this problem where they cant boot into recovery or bootloader? It's like the power button and vol keys are unresponsive even though they still work to turn on the device.
are you sure that you flashed the right recovery? but you should still be able to get the bootloader. are you pressing power + volume down(volume down, not both volume buttons. i noticed you wrote both volume buttons) to get into the bootloader?
I think I chose the right recovery the first version downloaded thru goo manager but it was the 2.2.0 version. I had the option on the of downloading the 2.2.1 zip or the .img but i downloaded the .img to just to flash with the current version of twrp that was working. There have been times were I have not been able to get into recovery on my atrix or htc but I've always been able to get into the bootloader this is the first time I've been locked out of my device kind of got me scared its not even a month old. So you say to get into bootloader you dont have to hold down both volume buttons? I will try again to power back up using the volume down and power button at same time... Wish me luck

yea, only power button and the volume down button.
quick question before I connect the battery does it make a difference whether or not I have it plugged in charging or connected to the PC while trying to boot into bootloader?
Okay so i was watching a video on youtube on how to get cm10 on my nexus 7, i bought the nexus 7 off a friend who rooted it for me and he had clockword recovery or whatever you call it set up on it. So the video said to download rom manager and then i went to download and downloaded the stable cm10 with gapps. Then it rebooted and what not and now its been stuck in the cyanogenmod spinning circle start up for about 2-3 hours now. So i held the volume and power button to get to the fastboot thing and shut the nexus off and then i restarted it and then.. the google sign came with the unlock icon and then the cyanogenmod circle came again -.- Please help if you can, sorry if any of this doesnt make any sense im new to all this. Thankyou in advance.
Power off fully, then hold the Vol+Pwr buttons down until it goes to the fastboot menu. Vol down to select recovery. I would do a factory reset and reflash the ROM + gapps.

Yea i did that right, it goes into the fastboot menu and i go to recovery mode. And when i click the power button, all that happens is that the black screen with google and the unlocked logo show up, and it stayed like that for like 2 hours again -.-
Do you know why that happens?
If you reflashed the rom I'm guessing a bad download.
ETA: Did you make a nandroid before installing? If so restore that.
Oh okay. So u suggested to do a hard reset. How exactly can i do that? My nexus wont load past the load up screen, on some occasions it goes past the google and unlock logo but then a cyanoggenmod spinning circle thing comes and then that just stays there.
Go to the bootloader (vol dwn+pwr), and plug into computer. Then select recovery mode.
Do a factory reset from there. Then reinstall CM10.

Oh okay, actually im really glad u just said this because i just tried this way. I powered off my tablet, then turned it on with vol dwn and power to get into the bootloader. Then i plugged my tablet into my laptop and now the volume keys wont let me scroll down to recovery mode. Pretty much the volume button becomes useless to scroll. Any help?
If the Vol buttons aren't working I'm out of ideas besides: try again? Otherwise you're going to have to wait for someone smarter than me. Sorry.
ETA: Found this guide: http://forum.xda-developers.com/showthread.php?t=1907796 Maybe it'll help you.
wait do i have to have the latest drivers for nexus 7 installed on my pc b4 i plug it in? If you do know, let me know where i can find them. If you dont no worries ill wait for someone else, thanks for your help so far.
Hey don't know if you got your Nexus working again but I saw this thread about the buttons not working. Not sure what version bootloader you have.
http://forum.xda-developers.com/showthread.php?t=1840675
Make sure you wipe the Cache and Dalvik Cache!!
When I first flashed CM, I got the infinite boot animation as well. I rebooted into recovery, did a wipe of my caches, and it was fine from that point on.
Also, when going from one rom from another, you gotta do a factory reset if you didn't already.
Yea I forgot to clear all the data.. nvr again but I can't get into recovery thats the problem. I have the 3.34 bootloader and it doesn't go to recovery and I tried plugging into my pc and then the volume rockers become useless. Any help plz?

I had the same problem this morning. After about an hour of messing with stuff I used mskip's toolkit to uninstall then reinstall the drivers. I
then rebooted into the bootloader without a cable and then connected the cable and the buttons were still responding. After that I updated
the bootloader to the latest release and I was about to boot into recovery.
I was using the Nexus 7 Toolkit, and used the option to boot into a recovery without flashing, on CWM 6.0.3.6. The device already had TWRP installed, but would not boot into it.
Now, I am stuck at the CWM screen with a "Warning: No file_contexts", and no commands available to me.
If I try to use the power/vol up/vol down combo to boot into fastboot, the device reboots, shows the Google splash screen for a second, and goes right back into the "busted" CWM. This happens regardless of the button combos, even if I just hold power for a while to try to boot normally.
Even though I'm partially in CWM, it's not recognized over usb via ADB, and I obviously can't get into fastboot to get it recognized that way. It was recognized correctly before.
If it matters, I had PA and TWRP installed before this happened.
Help!
Update: I let the battery drain itself dry overnight. After a re-charge and power on, still boots into the non-functional CWM. No fastboot/bootloader, even with the right key combo.
It's like I need to find some way to clear out of this temporary recovery that the toolkit created.
Similar problem
Does anyone have any insight on this one. I have a similar problem. A tablet was brought to me from a friend that is doing this. His son was "rooting" it when it developed this symptom. Looks like he was using CF-Auto-Root. When powering on you get the google screen then this auto root android screen and it loops. See screenshot.
I have been unable to boot the device any other way. Have tried fastboot and recovery many times with no success. When trying for fastboot with holding power, Volume up, and Volume down you get the Google screen once then black screen then Google again and it kicks back into the loop. Same as above poster every combination of button press/hold with or without USB has no effect other than the double Google screen as stated.
Device is not recognized on USB at any stage in this loop during my many attempts at fastboot or recovery.
Same as above if I could get it to do anything other than the loop like fastboot or recovery I think I can work it out what he has done.
Any help would be greatly appreciated.
Bump, anyone have thoughts on this? If I could just get into fastboot I'd be good, but the normal key combos do nothing, and I can't issue a reboot fastboot command since the PC won't recognize the device.
And yes, I'm sure I have my drivers set up correctly.
Anybody? What causes a device to not be able to boot to fastboot or recovery. If I can't fix it I would like to know why.
Looks like we might be hosed here. Don't see to many post on here that don't get some suggestions.
Yeah, even after letting the battery drain completely, I can only get into the hosed recovery mode, with no functions available. Fastboot key combos do nothing. I'm still stuck.
Can't anyone shed some light on this? Am I hardbricked? Would a picture of the recovery that I get into help?
Here is the only screen I can get into, regardless of key combos held during start up. This first happened after booting into temp recovery.
Help! About to have to throw my Nexus 7 in the trash!
does nexus use hibernation in place of shutdown, because sometimes i suspect my nexus does not shutdown? have u searched from this angle

I wouldn't think so; I have let the battery drain to dry by leaving it on that recovery screen until dead, and it just boots right back into it regardless.
removing battery connections maybe??

Yes. It doesn't get recognized/doesn't connect via adb, so no commands work. And I'm positive it's not a driver issue.

I was on 4.3 PA and tried jumping up to CM11, this appears to have happened to me. Interesting...
Are you unable to get into fastboot by holding down volume up volume down and power? I did this, then used the root toolkit and was able to flash stock 4.4. Back up and running now.
No, vol up + vol down + power does nothing for me except get into this recovery.
Bumping this one more time. Anyone have any ideas?
After flashing CM 11, I haven't been able to get past the phone set up (instantly crashes). After downloading a CM 10.1 ROM on to the phone and wiping the phone, I also deleted the ROM. Then the phone restarted itself and now I'm just stuck at the Google logo, and cannot access recovery. I remember having a similar issue on the Galaxy S, but don't remember the solution.
Trying to turn the phone off by holding the power button down for ten seconds just restarts the phone in the same state.
Any ideas?
Try to turn it off completely, start the phone in fastboot (bootloader) mode, and then flash the factory image
Holding down the power button for 10 seconds just restarts the phone. Is the battery removable?

That worked, thanks!
You just saved me a lot of time waiting for the battery to die
Just out of curiosity, does flashing the stock ROM keep root and CWM or do I have to install these again?

Is it a flashable zip or are you flashing a factory image?
If your flashing the factory image and you're using the flashall.bat yes you will have to reflash root and a recovery
It was a factory image. Is there a need for a custom recovery or is the default fine?

So after trying to boot to recovery, my Nexus 7 wifi keeps rebooting . What it will do is it will boot to the bootloader, then immediatly go to recovery, I have CWM 6.0.4.3. The recovery begins to load, however befor options apperar it reboots and restarts this process. It is unresposive to the power and volume buttons. I am not sure how to get it out of this cycle, other than perhaps waiting for the battery to die. Any help would be great, thanks in advance.

Crack the back casing open and wedge the battery terminals out with something plastic. If you don't feel safe, why not hold power and down to force your way into the bootloader yourself.

Even after forcing the nexus off, whether by using the power button, letting the battery die, or removing the battery, as soon as it boots it does the same thing, even if I am holding volume down + power.

Ah, I see. What was the last thing you did before this started? Before flashing recovery, I mean. Did you check md5 before flashing recovery?

I haven't reflashed the recovery in a while, so the recovery itself *should* be fine, in theory. The last thing I did was flash Xenon HD latest, then franco.kernel, via recovery. For whatever reason, Xenon HD would bootloop, perhaps it is incompatable with franco. I then forced it off and used power + vol down to boot to fastboot then recovery, the recovery didn't load all the way, and thus the cycle began.
I have a same problem after flash xenon hd

The incompatablility with franco or the recovery loop leaving the device entirely useless?
I got the same problem after flashing XenonHD on my grouper,
I had checked for two weeks and finally I came over it by this way:
1- make sure you have proper ADB drivers on your windows
2- create an executable batch file (eg. boot.bat) with below contents:
:loop
adb reboot-bootloader
goto loop
3- connect Nexus 7 via usb to PC
4- run boot.bat
5- power it on and press Vol - key several times and with erratically, keep trying. it worked for me.
6- after unknown cycles of recovery bootloop finally it enters to Fastboot mode.
7- flash your recovery by desired one (I recommend TWRP) and run your recovery and wipe everything and flash a good ROM
8- good luck
