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!

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?

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?

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.
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

It won't do anything when you hold the vol down and plug the usb in?

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.

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?

Big ups to thecubed, but I found I needed a few more steps. When you get not enough memory message, hit arrow button back to TWRP home screen. Then reboot, shut off again, then go into download mode. 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.

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.

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
I dont know what happened but I rebooted my phone today and it booted into fastboot.. I cannot in any way get it to boot normally. The buttons are not being held down and I have tried to pull the battery.. I dont get it, anyone else have this issue and fixed it have an idea??
Was it stock (including recovery) or modified?
I would try to fastboot the TWRP over and then boot into that (Power & Vol+). But then... I seldom run stock.

Phones boots into fastboot mode in two situations
1. Pressing vol up and power button simultaneously for rebooting
2. Your phone doesn't have recovery AND any OS installed
I guess your vol up button is constantly in pressed state.
Second situation cannot occur unless you wipe your system and recovery manually. So you are in the first situation
Your phone's vol up button is constantly in pressed state or electrically shorted may be due to water entering the case
Solution: You will have to open your phone's case and clean the area near the volume button. I guess you had opened the case/body and didn't fit it properly.

Reinstall twrp from fastboot & install rom
hello and thanks in advance. I recently installed twrp on my device and somehow deleted entire os. while in twrp I was informed of this but as luck would have it experienced a power outage, phone died and now adb is not finding device. since deleting os is it possible to get comp to locate it? all I get is the blue led and if I try to volume down power to boot recovery ligts go out. I do get a chime saying something is connected to comp but I cannot locate it. any advice would be great.
Have you tried to follow instructions to reflash TWRP? Can you put the phone in bootloader/fastboot mode?

Maybe missing something here but if can get to TWRP, power off then on holding volume up, you can flash any rom. Not volume down on my phone to get to TWRP, is volume up.

No way if you don't have adb working. Again, if you hold volume up button while pressing power on button, then release power on button as soon as you see boot screen, do you get recovery screen?
No screen reaction at all. Only the led when connected by us to computer it seems to charge and led stays lit blue after fully charged and red when still charging. I was hoping maybe there was a shell comand that would maybe push data enough to get into recovery at least.
