Nexus rebooting to recovery repeatedly - Nexus 7 Q&A, Help & Troubleshooting

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

Just start again, sometimes it messes up, but you generally just start again with flashing the clockworkmod. Make sure the download wasnt corrupted by doanloading everything again though, although ignore the bit about adb rboot bootloader, you need to start the phone manually by use power + volume-down key combination to get into bootloader when its powered off and continue from point 5.
Thanks, I will give that a try

Relac, its actually pretty hard to completely bust these things. Dont quote me on that though lol
Don't freak out. I'm sure you're fine.
Unlocking the bootloader on my N10 caused me to hang at the X. Wiping data fixed it for me. Try the following:
1. Reboot into Fast Boot
2. Select Recovery using volume rocker. Hit power to select. You'll get the android mascot with the red exclamation point.
4. Press Power and Volume Up at the same time.
5. Choose to wipe all data. Confirm the selection.
6. Reboot.

So I didn't originally flash the recovery image, just booted into it. So I tried that again, but there is nowhere to find the SU_BusyBox_Pack.zip. I tried the sideload method, but ADB can't find my device any more. It shows nothing when I do adb devices.
what else can I try ?
Were you able to try wiping data through the stock recovery?

I got stuck after just booting into recovery as well and immediately exit. Just use the volume key and change it until you see recovery, without going into it, I just fastboot flash recovery recovery.img from pc, then factory reset.

[Q] How to reboot into recovery?

If you get stuck in a boot loop, is it really the only way, is to hook the n7 up to a pc? It's not exactly like you can pull the battery....

long pressing(10-20 seconds) the power button will reboot the device. if you also press and hold the volume down button when it reboots, it'll take you into the bootloader. from the bootloader, press the recovery option.

update your bootloader. you should be able to get into your recovery with the recovery option if you connect your device via usb to your computer.

I tried connecting the device to my computer via USB before selecting recovery. When I do that, volume up/down and power do nothing! So I have to reboot by holding power again. What do you think now?
I didn't realize I had to update the bootloader I was in the process of updating my ROM from SmoothROM 4.1.2 to Modaco 4.2 and it did not flash properly. So at this point, I cannot boot up. I'm stuck here.

while in the bootloader, connect via usb and use fastboot to.. fastboot boot recovery recoveryname.img

Can't get into fastboot/bootloader, bricked?

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.

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?

[Q] Stuck at Google log, can't access recovery

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?

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?

[Q] Help please !! Autostart f bootloop "Recovery Booting screen" after flashing Twrp
Long time xda lurker here,
I have just thrown my t mobile note 3 into an autostarting bootloop that i dont know how to recover from. I have successfully used this same process 4 times on 4 devices, S 3, tab 2,galaxy light and lg volt. Although this time i used mobile odin as the flash tool.
I flashed twrp to the note 3 because it didnt have any recovery at all. Ive had this phone rooted for about a year without a recovery. After flashing twrp now it constantly autostarts to the logo screen and in top left corner it says recovery booting then it restarts with the same result. Ive tried leaving the battery out for an hour but when i reinsert it, i dont even have to push power and it starts bootlooping again. I cant get in download mode,safe mode, recovery mode, anything mode. Im at a loss. Any advice,any at would be appreciated. Is there any way to fix this.

If the phone turns on by itself when you put the battery in then it's almost certainly the Power switch on the mainboard or the plastic Power button (which is what we interact with).
If that's happening on your phone the first thing to check is the case (if present), to make sure it's not pressing on the Power button.
Next would be to take the phone apart and gently pry the plastic Power button off (there's two legs that hold it in - be careful not to snap them off).
Finally, the Power switch itself - it may just be gunked up, in which case you can try compressed air or electronic contact cleaner (be sure to remove the battery first!) and exercise the switch to get it working.
Otherwise you'll have to replace the switch.
I am going to give that a look right now but it wasnt stuck before flashing twrp. Mobile odin said it was going to restart then it immediately started doing this.
Ok going to check power button now.

I've had this before and in my case the Recovery is in place but the boot loop will not let you access it.
Try forcing the phone down by holding down power for >8secs. Then as soon as it goes off, press Vol Up + Home + Power to go to Recovery. If it works, Factory Reset and see if it starts.
If that doesn't work, (Factory) then try flashing a ROM from your extSD if you have one, or flash the TWRP Recovery from there.
If that doesn't work either, remove battery and as you put it back in, have Home + Vol Down + Power pressed as you push battery in - just have battery sitting ready to push in with 1 finger holding it, press the 3 buttons and push battery home. Go into DL mode and Odin a firmware. Get the TWRP .tar file from TeamWiz and flash it from Odin after the ROM. Take the tick out of 'Auto Reboot for both processes. Take phone down, restart in Recovery and flash SuperSU.
Ok journeyman16,
Trying those 1 by 1 right now. Hopefully 1 will work, thanks for reply.

Nothing stops the "recovery booting" bootloop. Although for some reason i now have to actually push the power button before the power comes on after a reinsertion of the battery. But still same bootloop. Idk getting really discouraged with this one.
By the way, I do have an ext SD card with 2 nandroid and a titanium backup but they are useless with what it's doing

That's strange. It might be a timing issue where you aren't doing the DL mode buttons quick enough. DL mode should be available if it gets far enough to try Recovery boot. Did you try having the 3 buttons pressed and holding them down before pushing the battery in? (as in Vol Down + Menu + Power) I ask because it can be awkward to do it all at once - and it takes only a split-second lift of a finger to miss the boot.

Yes i have tried it a hundred times at least, lol. I was holding the buttons then pressing it against my leg to insert the battery fully.
I dont understand it either. Im at the point of just leaving the battery out for about 8 hrs then trying again, basically a hope and a prayer situation.

After my 2 1/2 hrs of sleep i put the battery back n and it went in download mode thankfully.
Tried to start it normally but it just loops to logo without recovery booting on thr screen.
Guess i wiped it somehow with mobile odin. Idk.
Thanks for all the help.
Ill be using regular odin when i get home to restore it.

Note 3 is working better than new
As an update, I ended up putting the tweaked ROM with custom kernal on my device and it just purs along at lightning speed now.That's an absolutely wonderful ROM. I highly recommend it. Only problem is if the battery dies it goes into a bootloop but as soon as I connect the charger it boots up. Not a ROM problem I don't believe though. Oh well thanks for the help guys.
