Fastboot into recovery not working - Nexus 7 Q&A, Help & Troubleshooting

When i try to reboot into recovery from fastboot, I get stuck at the google logo and nothing happens. However, when I try to boot into recovery from android with the expanded power menu or usuing the toolkit, it works without a hitch? Does this mean I have a dodgy tablet?

Apparently this is an issue for a lot of people including myself. I haven't found a solution to enter recovery from the fast boot menu other than using an app like quick reboot from the play store.
If you find a permanent solution please share it here thanks.

This is an issue for everyone and it's a problem with the bootloader. The only way to get to recovery from the fastboot menu is to have your USB cable plugged into both the Nexus 7 and your running computer.

Cannot get to CWM

Greetings,
I have successfully unlocked and rooted my Nexus 7. Now I'm attempting to flash CWM to the device, and it seems to have successfully gone, however I can't seem to boot to it. I've used the Google Nexus 7 Toolkit V2 which says it successfully flashed it, but still am unable to boot into cwm.
After shutting down the device I hold the up + down + power buttons down and all it does is boots into fastboot mode. If I let go of the buttons when I see the google image then the device just boots normally. Can anyone clarify what I'm doing wrong here? Cheers.
From fastboot, if you hook up your nexus to the computer, with the cable included then select 'recovery' by toggling thru the choices with volume and using the power button to select, it should boot into cwm. It only boots when connected to a computer, it's a known bug Next time do a forum search, dont start a new thread.

same problem like you,
i install rom toobox from market.
in that app, use rebooter, then choose reboot into recovery.

how to boot into cwm?

I have rooted using the rooting toolkit.
Great toolkit by the way.
That gave me a cwm.
I installed ROM manager n choose the cwm touch.
Now I have a nice touch version cwm.
But I can only enter it via ROM toolbox or ROM manager in app option
The power + volume own combo doesn't work anymore.
Naturally I googled n search about this.
Is a common issue and the solution is usually this 2
Use adb, I have no idea how.
Plug a USB cable.
I love the USB cable idea but I don't get how it works.
There is no description on it.
I plug my USB cable, and try the combo,
I got into boot menu, I navigate to recovery, and it got stuck there
What should I do?
I'm worry to flash anything fearing I can't get back to recovery if my tab don't boot.
Well one way to get abound it is any CM10 Rom. You old the power button, click rebppt then select reboot recovery to reboot into it. It kinda is a problem if you don't want to flash anything though.........

dumb questions: did you plug it into computer? does adb work when you do so? If these two are true, I imagine the three button method should work when plugged in.
(But I'm just speculating, really.)
If adb does work, then worst case scenario you should be able to "adb reboot bootloader".

You don't have a computer/laptop?
Maybe you don't need adb, I was just speculating. I wouldn't know since I basically have adb all the time.
Choose boot into recovery in Tomorrow manager or grab terminal emulate of play and type

Thanks for the USB Trick
I manage to get it to work already.
Just plug the USB cable to the tablet, and connect it to a computer.
Then use the power and volume down combo to boot into cwm recovery.
Previously I tried the combo only with the USB cable, but not plugged to a computer.
why we need to plug in a pc???, my phone doesnt need....
just power + volume down!

How do you do it?
If I use that key combo,
It will lead me to a menu, I use volume button to select recovery,
The tab will then just stuck at the Google logo and never enter cwm.
It is a bug in the bootloader... many threads about it.
Simple fix use quickboot app. Press a button and you're in recovery. No keyboard needed.

I just went into Fastboot, Power, both volume keys then scrolled to recovery... worked like a charm... dunno why it wouldnt.
Unless set by CWM, Nexus 7 will automatically try to restore the stock recovery that's why you are stuck. Once in CWM recovery, there should be an option to block android from doing so.

It is really easy to get into Clockworkmod Recovery. Install Rom Manager vv5.0.2.1 from the market and Flash ClockworkMod Recovery. It should list recovery 6.0.1.0. Then choose Reboot into Recovery from Rom Manager. Done. Now you have the full CWM recovery with access to all the things you don't have in stock recovery.

is this normal for a bootloader ?

So my name is kinda weird. Sometimes glgps persists ans drains the battery. And I can't get into recovery. Here's a pic of my recovery. It seems like fields aren't filled in. (obviously i hid my serial) What gives?
thats normal, looks exactly like the ones I had, to get into recovery you have to hook up to usb
Your bootloader is still locked. You need to unlock to get into recovery.
Edit: Oops, my bad. You don't need to be unlocked to access recovery apparently.

It is a pic for your Bootloader (Fastboot Mode). Using Volume Up/Down, you can select wether boot the device, or reboot into recovery. When you selected what you want, press Power.
Also, yes the product name is fine : Grouper is the product name of Nexus 7.
first you need unlock

Sorry mods. Please move this to q&a.
Thanks to the replies. You have to have USB to get into recovery? No other android device I've ever had , besides the Xoom needed that. You just selected recovery mode from boot loader. All well. I guess all are different.

Plug into usb and use the volume buttons to select reboot recovery then power .. when the android with the red triangle comes up you hit power+vol up and the options come up, I'm talking about stock recovery not CWM pretty sure I read people couldnt get into recovery without it plugged up but I couldve remembered wrong

Cept mine doesn't. When I select recovery mode it hangs at INI (white Google on a black background)
If you think the recovery is borked and want to reflash it , download the factory image from here, extract recovery.img from the image and put it in your platform-tools folder on your PC in ADB and once you are in bootloader from cmd prompt type
fastboot erase recovery
fastboot flash recovery recovery.img
fastboot reboot-bootloader
that is how I go back and forth between CWM and stock

Guys,
@animal gets stuck on google logo, that means the system is also broken..
You got to flash back the whole stock rom.

Do yourself a favor and download the Nexus 7 Toolkit from the Development section - it's allows you to do anything you need to via nice, easy to use menus (including downloading and reverting back to stock Google ROM). It's a *great* tool for the Nexus 7.

Try using a Nexus 4 Toolkit. It makes things a lot easier for you if you wish to install a recovery.
For the bootloader problem. I'm not sure whats causing it.
The android laying down with exclamation mark is the stock recovery. What you can do is;
install twrp through GooManager. Install GooManager from market, Press menu then install openrecoveryscript.
Then you need to overwrite the stock recovery. Go in the system with root explorer go into system and find the recovery-from.boot.p and change the name by adding .bak to it so you can get it back if needed. Then try reboot into recovery.
Hope this helps you out.

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
Sent from my Nexus 7
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?
