I unlocked my N7 3G with WugFresh tool and then I rooted and installed a custom recovery.
Everytime I power on my device by pressing Vol DOWN + POWER ON my device is in fastboot mode. But If I try to run adb devices, no devices are found. While if I launch recovery and run the same command, my device is listed.
So I don't understand why I can't communicate with my device if I power on it in fastboot mode, but only if launch it in recovery mode or I power on it with USB debug on.
So I couldn't flash my custom recovery with this command:
Code:
fastboot flash recovery recovery-CWM-tilapia-regular.img
but I had to use WugFresh's tool to flash a custom recovery, in fact when this program launch command to power on device in fastboot mode, it works! I don't understand why I can't do it manually but only throught this software
Try using the command : fastboot devices

Adb has no access in bootloader for future reference, only in os and recovery

I am trying to root my Nexus 10. This is what I did, but it ended up bricked!
I installed the Android SDK on my Windows 7 computer, and downloaded the Android USB drivers and tools.
I turned on USB debugging, and checked I could see the device with adb list devices.
I downloaded recovery-clockwork-touch-6.0.4.3-manta.img, booted the tablet into bootloader, and flashed it
Code:
fastboot oem unlock
fastboot flash recovery recovery-clockwork-touch-6.0.4.3-manta.img
That seemed to work, so I went into recovery, but recovery had all sorts of errors - it couldn't find the sdcard, or mount most of the partitions.
Rebooting stops in the animated logo, apparently for ever.
I have since tried to reload the factory image, but the computer no longer recognises the device - fastboot devices returns nothing.
Help!!!
[Later] The tablet was running the latest O/S (if I could boot it, I could tell you the number!)
Things have got worse. Now, when I go into bootloader mode, the volume keys don't do anything any more, so I can't even turn it off now
Make sure fastboot is set up properly, may need to reinstall drivers or try another computer or try another USB

I have a feeling the recovery you flashed was corrupt in some way, did you by chance check the md5sum of the image first?
If your able to get fastboot to recognize tab
fastboot erase recovery
fastboot erase system -w
fastboot erase boot
Download latest twrp recovery
Check md5sum
fastboot flash recovery nameofrecovery.img
Then you will either need to flash stock system.img from fastboot or boot to new recovery and adb sideload a ROM
Hopefully your emmc is not to severely corrupt to all this, best of luck!

Thanks, that was pretty much what I did. The trick was to get it working in boot loader mode. I kept trying to reboot it, and in the end holding down power plus both volume up and down all at the same time for 2 beeps made it work.

I have the same problem, however I can't access my Nexus 10, fastboot devices and adb devices gives back an empty line, so I can't access the N10 with fastboot or adb, to lash a ROM. Factory reset from CWM doesn't work, ˛internal card can't be accessed from CWM ("E: Can't mount /sdcard).
How can I get out of this trouble? (Solutions in forums usually involve reflashing with fastboot or formatting the external SD card. These solutions don't work here...
Any idea would be highly appreciated...

Keep trying to reboot into bootloader mode, until it works. Hold down power and both volume buttons at the same time until it beeps twice. If the volume buttons then work to change the option on the left, but fastboot devices on the pc shows nothing, try reinstalling the Google drivers on the pc (via Device Manager, update drivers, have disk). (may have missed out a step in device manager instructions, but there are plenty of Google hits on installing add drivers if you don't already know how).

Sorry, I don't understand what you mean.
I can get into into bootloader mode after keeping the 3 buttons (power+volume up+volume down) pushed together (after two beeps). From there I can't boot the device. (Boot gets into the Google animation forever), so as factory reset.
Also device manager doesn't see the N10, so I can't update the drivers on my PC.

After some repeated turning off and on, now I can see the N10 from the PC (also updated the USB drivers to be on the safe side).
If I enter the bootloader, fastboot sees the N10 in a normal form, if from there I go into recovery mode, adb sees the N10 in recovery mode. Should I proceed from here by using fastboot, or rather adb?
Csaba
You should just use volume up + power (or the whatever the volume rocker button closer to power key) never had it beep to get there
To both of you, follow the steps from above, so long as it isn't a hardware issue this will get you working

Glad you have managed to make the device visible again (it's really scary when you can't, I know from yesterday!).
Go into bootloader mode (not recovery), and follow the fastboot instructions demkantor gave earlier in the thread.
Get your factory image from https://developers.google.com/android/nexus/images#mantaray.
Get TWRP recovery from http://teamw.in/project/twrp2/128.
At least, that's how I did it.

How do I check md5sum?
Use this for windows

Or terminal for Linux
md5sum nameoffile.extention

Thank you very much. Tablet is up and running again. :good:
Now, my next question, after being unsuccessful with CWM, I tried using TWRP for rooting the tablet, however it wouldnt start.
When I go from the bootloader into recovery mode only a laying android figure is displayed with a red triangle with an exclamation mark inside.
I have USB debugging enabled. What can be the problem?

That means you don't have twrp installed. That's the stock recovery. You can download twrp and use fastboot yo flash it or try the app twrp intaller which dies or fir you

hello
so I wanted to get my nexus 4 to complete stock mode and failed in the process.
I followed a guide that was posted on here and
1. locked the bootloader
2. put 3 files (rom, recovery, boot animation?) into the phone and went to flash them
3. rom installation failed but I went and installed recovery and boot
now the phone is stuck at google booting screen and wont go past it. bootloader gives me dead android with triangle and I can't get into adb because it says device is offline.
can anyone tell me a way to fix this?
Unlock the bootloader and flash the factory image in fastboot

If you have an unlocked bootloader and can boot into it, does it not recognize your phone or simply not allow you to run commands? My download mode reads as DISABLED in my bootloader and I can run fastboot commands. I think you're a little confused on terminology, too. You'd sideload software via ADB with TWRP or for an OTA, your stock recovery. You'd fastboot flash partitions via the bootloader.

I can boot into fast boot mode by hardware button combo pressed but its not recognising any fast boot or ADB commands when I connect it on my laptop
When connected by USB and in your bootloader, run 'fastboot devices' and if it doesn't show your serial # then it isn't recognizing your phone, likely a driver issue.

Do not try to do that. We have a lot of bricked devices (Including Mine) after we tried rolling back to Marshmallow. Just a warning. If you still want to take a risk, go ahead by all means.
Driver issue....resolved.....Working now!!...Thank you

No problem. I would listen to Indian84 and stay on Nougat until you can flash full factory images.
