how to boot into cwm? - Nexus 7 Q&A, Help & Troubleshooting

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.

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.

recovery possible without vol-down?

i was reflashing my DHD to fix some issues i was having with it, but the reflash (from cm7 to virtuous unity) has left me in a boot loop and i'm not sure how to get out of it as one ofthe recent problems with my phone was that the vol-down key isn't working.
is there a way to boot into recovery and reflash again without the use of the vol-down key?
i've tried abd, but the phone restarts before a point where abd with pick it up so i think i might be a bit stuck.
any ideas?
thanks in advance.

as i understand, he is stuck at bootloop.
try to use something like pen or toothpick to press vol down button(if you dont have cover press) and then try to boot in recovery.
If you can turn on your phone, download 4ext and touch recovery

you could always just try running an ruu, it will continue retying adb commands for a set period of time. so just start running through it while the device is in the boot loop.
was stuck in a boot loop that was occuring before abd could see the phone with a non-functioning vol-down key so i couldn't boot into recovery.
However, it turns out that i was able to get a pin under the vol-down key and lift it enough to use the pin to press it during power on and was able to then get into recovery and do a full reset and re-apply a fresh firmware and it's working fine now (minus the vol-down key still), but thanks for all the tips and suggestions.

Can't Enter Stock Recovery

I tried unrooting my phone, but it got stuck in a boot loop.
When I try to enter to recovery mode to factory reset I get an android lying on its back with a red triangle.
I've tried a bunch of combinations of buttons, but the phone just turns off if I hold power + volume up.
In cmd prompt on the PC type: adb reboot recovery. That should work.

that is the stock recovery. what you want to do is flash the factory img via the bootloader/fastboot.
You have the buttons right, but you don't really hold the two down. It's a bit tricky but once you figure out the exact way to do it, it's easy.
Press and hold the power button then immediately after press volume up. Then let go. The menu will appear.

Your device should be called Nexus 4 and not Samsung. Install the drivers from here http://forum.xda-developers.com/showthread.php?t=1996051, after that connect the phone through usb, look in device manager and delete the device. Reconnect again and choose manualy wich drivers to install and choose the driver you just installed. Now your device is called Nexus 4.
your stock recovery over wrote your custom recovery and that made the little android with the triangle come up. all you have to do is reflash a custom recovery using fastboot.
go to zedomax channel at www.nexus4root.com and he gives you video instructions using the cmd on your computer
Try this:
Go into bootloader and recovery
You will see the android with the red triangle
hold power and press volume up (tricky part)
wipe cache
If this doesnt work try doing a factory reset instead

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.

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] LG G2 Stuck in TWRP & Device not recognized

Someone please comment with help! My phone was rooted and I flashed TWRP and saved a restore rom of "Stock Root". My phone must have gotten warm and now it only boots into TWRP. I have tried flashing my recovery (Doesn't work), using ADB Sideloader (Never Finishes running), Using Terminal Command (how do I navigate to Start Folder?), and using ADB commands to push file. The big problem I am seeing is my computer is saying that drivers aren't installed. I re-install the drivers I used when I rooted but still nothing. I run adb devices and it is not listed. I just want to get back to my stock root or be able to flash a CM stable. Please help!
I have been all over this site and it is always helpful but this time my searches have not led to sucsess...
Download and install koush adb drivers and then pc will see ur phone and I guess u know the rest.

Re: [FIX] Installed TWRP and now you're stuck after OTA?
chakra said:
OK
1. Turn device off by holding power key down until bootloop stops.
2. Hold power, down volume and where the home key would be.
3. choose yes factory reset, should take you back to recovery....

Here is the original directions I followed. Saved my phone. Only works if you have flashable ROM in recovery.
The key thing here is hold the power and vol down and then where the home screen is normally on your blank screen hold down all 3

Need help - possibly bricked?

Hey guys,
So my Verizon G2 was on the stock rom with root. I wanted to install TWRP on it and flash a rom but couldn't get to that due to the fact that I couldn't get TWRP running after I tried flashing it with Flashify(I did this after having the first OTA). Another OTA came up today and I legit accidentally hit install now. I'm currently stuck at fastboot and I can't even get into download mode or anything. Hard factory reset doesn't work either, I just get :
[2950] Fastboot mode started
[2970] udc_start()
and nothing happens. I really hope I didn't brick my phone.. Please help!
Thank you!
I was given a G2 that was bricked, all it would do is sit on the LG screen forever. I followed this guide: http://forum.xda-developers.com/showthread.php?t=2448960 and put the factory firmware on the phone. I never took any of the OTA's cause the phone wouldn't even boot up, but I would think its close to the same situation. The guide posted above worked for me

Damnit-- I am in the same boat. Vol down or up when plugging in does nothing-- just a glowing black screen after the LG logo. Device manager is only seeing it as a qhusb_bulk device even though the lg drivers are installed. None of the tools recognize it at this point. Almost ready to give up and call it bricked.
Did you make sure the phone is completely off? If you hold power and volume down buttons, it will shut off. Once its completely off you hold the volume down and continue to hold it while your plugging in the USB. I believe the drivers have to be installed as well.

Listen, to power off the device press and hold the power button, it may take up to 10-15 sec but it will power down.
Go to this thread and follow the instructions.
http://forum.xda-developers.com/showthread.php?t=2448960
If you follow them exactly as stated, it will flash you to 100% out of the box stock, you WILL lose root and SD storage FYI.
I did this last night and it does work, just don't move to the next step until you are 100% sure you've completed the last.

I was able to finally get TWRP onto my phone last night, so I'm no longer stuck at fastboot. However, I'm not just stuck at recovery. Even after flashing a custom rom, I keep getting sent back to recovery. I did notice however, if I go to backup, the data partition is at 0mb, despite formatting data and cache already. I tried the dd commands in the link above with adb, and I get nothing(file doesn't exist). I'm at a loss. What can I do now?

Lg Flashtool may work for you, but it didnt for me as it couldnt validate cdc serial. I downloaded LG update recovery tool from LG, and i have a phone agqin. But you are now going to be updated to VS98012B, and you will not be able to root again. Hope this helped....

Thanks for the help, but do I type that into the command prompt on my computer? Do I go into the terminal command option in TWRP? Totally confused on how to do it...
I know it took me all night...im kinda noobie...
Ok bear with me...use the second option from thecubes link, when in TWRP, go into terminal command, it will open a bunch of file options...ignore those and hit select on bottom right. That will start the command which will give you two sets of 6 figure numbers beginning with 6 and an out of memory error. Again ignore....hit back arrow till back to main screen and try what i said before. Again I am kinda a noob, so if my directions are confusing be patient and i will try to help.

To enter download mode power off phone, hold up volume only then plug into pc. Once there you should be stuck at logo screen but now lg updater will recognize your device.
