Hi,
i have a problem with rooting my nexus 10: After installing te recovery, i was to slow updating the drivers.
No i have a bootloop, my device dont boot the OS, it hangs on the animation.
I can enter the bootlaoder, so i assume that i dint brick the device.
What should i do? flash the factory image?
plz help
After fastboot oem unlock you need to do a factory reset... A userdata.img is included in stock images from Google at https://developers.google.com/android/nexus/images#mantarayjop40c
Sent from my Galaxy Nexus using xda app-developers app
so i have to flash this image in fastboot?
fastboot flash userdata.img ?
i just dl the factory image from here https://developers.google.com/android/nexus/images and run the flash-all bat but still a bootloop
fastboot flash userdata userdata.img
ok, i just hit this, letz hope it works, im a bit worried that i brick the device
edit : ok still a bootloop ;(
Do cache.img in the same way... See if that fixes it ( I did all this earlier too when I got a bootloop in the same manner)

ok. ill gonna try it, how long shoul i wait, until im sure that it is a bootloop? 2 min?
yeeaahhh ill got a boot
should i reflash the factory image just to get sure all ist stock again, and all what i do is reverted?
I didn't flash system.img on mine after updating to latest stock (mine arrived with older firmware than stock image)... especially don't do it if you want to keep superuser installed.

Bootloop and "Downloading-do not turn off target!!" in recovery
Hi there,
New here so please be gentle if possible Opened box, updated OTA firmware to latest 4.2, enabled developer mode & USB, used adb reboot fastboot and adb oem unlock to unlock. Confirmed unlock and now stuck in a bootloop. When I use Power+Down to go into recovery, I get the Android picture stating "Downloading... do not turn off target!!!". Fastboot and adb commands won't work, so I can't figure out how to get past this point. Any ideas? Thanks in advance.
It's a pain to get into the bootloader. Always takes me a few tries. Try holding down power and both vol keys. I have to do it several times, sometimes just vol - sometimes both. Eventually it will go to the bootloader without the downloading dialog.

Yes you are in Download mode not recovery or fastboot ...
Hold down BOTH volume keys and the power button to get to fastboot mode .. and you can get to recovery from there ...

Big thanks to both of you who replied with hints. I confirm that holding down BOTH volume keys and power brought me into regular fastboot. I went into recovery (then pressed up+power) and did a factory reset. The (unlocked) Nexus then booted properly after that. I have had no issues since. *fingers crossed*
i have the same problem right now. im using the nexus10toolkit and I have reflashed it back to stock and unroot it. Im still stuck at bootloop. any ideas?

Go back to fastboot. Once in fastboot, go into RECOVERY. You'll get android andy on its back with red exclamation point. Hold down POWER then briefly press VOLUME UP. You should then have the menus visible. Now just wipe your device. Reboot and it should work now. If not do the relock, unlock, relock and fastboot recovery and wipe data.

Sry for waking up this thread. I am in the same situation as this user, tried to use the nexus tool kit, reflashed the stock factory image and unrooted it and after everything was done its stuck at the google logo. If i try to acces fastboot i always go into download mode. It says downloading...do not turn off target !!
If i press the power button it restarts the device and again stuck in bootloop at the google logo. I cant unlock or lock because i cant get into fastboot at all.
Help?
LE: i havent manually booted in fastboot mode for so long that i forgot i have to press both the volume buttons for it, was only pressing vol down. Silly me, sorry for the post

I have tried 100 times to boot in fastboot mode. I've done every combination of power, volume up, and volume down imaginable. All my tablet does is vibrate. It will boot to the nexus logo but stays in a boot loop. How can I get to the fastboot? Is it just bricked beyond repair. I was attempting to unlock it with the nexus toolkit and it rebooted my device during the process and started this bootloop. Can anyone help?????
Can adb find your device when in bootloop? If so
adb reboot bootloader
If not you will need to continue trying to get into fastboot mode with the hardware keys. I doubt you are bricked as the bootloader is still there or it wouldn't make it to splash screen

Hi guys !
I need your help for trying to recover my information from my Nexus 4... (Thanks in advance)
First, my N4 is:
With the screen cracked, so, the bottom half of the screen is not responding to any touch
Locked with a lock pattern (and because of the damaged screen, I can't unlock the phone)
With stock Android
With USB debugging on
Not rooted
With no other modification whatsoever (No custom ROM or recovery mode, etc)
First I tried the obvious, I connected the N4 to my computer expecting a miracle; as the phone is locked, and I can't unlock it, ADB just didn't worked.
I also tried sending a .zip thought "adb sideload" (using the stock recovery mode) to delete the files where the lock pattern is, but an "signature verification error" occurred (because the phone is not rooted, I guess). I've tried to delete the files with "adb -d shell" but (obviously) as ADB is not working, a "device not found" error showed up.
So I guess the question here is... What are my options ? Is there any way I can recover my photos and files ?
Thanks in advance!
Try going into recovery and using adb from there. Turn off the phone then turn it boot into the bootloader using volume down and power. Use the volume rockers to scroll and highlight Recovery mode, then use power to select it. Once in recovery press and hold power, then volume up to enter the menu. Then try "adb devices", and if the phone is recognized you can use what you want.

Hi chromium96 !
That didn't work.. :S
Any other idea ?

Flash a custom recovery and boot into it... I think custom recoveries support adb.. If USB debugging is ON and proper drivers are installed on your PC, you can do 'adb pull' for the necessary files

To flash the recovery you will need to unlock your bootloader which is meant to wipe all your data. However if you flash the recovery right after unlocking the bootloader (no reboot in between) the data should not get wiped.

Yes.. I have done that too.. It doesn't wipe the data.. Just flash cwm, right after the boot loader unlock..

Today I tried booting up to recovery (power+vol down), after choosing Recovery Mode from the menu and hitting Power button, it gets to a screen with the green Android guy with a red triangle and just stays there.
So I rebooted the phone. Launch Nexus Root Toolkit, I tried to install CWM or TWRP, neither works. It gets to the same recovery mode and gets stuck there, only this time, it gets stuck on the Google logo instead of the Android guy with red triangle. I even try to flash stock recovery, and it also doesn't work.
Why can't I get into CWM or TWRP nor can I flash them?
Thanks for any help.

Be sure u are bootloader unlocked.
Android guy is normal... Is a safety step before entering on stock recovery, to pass that: hold power and hit once volume +
Probably u cant flash images cuz fastboot isnt working(old fastboot.exe file), wrong recovery file,...

Bootloader was unlocked. I launched the CMD Prompt from Nexus Root Toolkit and ran the fastboot command to manually flash the downloaded CWM and it worked.
Code:
adb reboot bootloader
fastboot flash recovery recovery-clockwork-x.x.x.x-mako.img
So maybe something's odd about the simple one-click utilities in Nexus Root Toolkit that is not working.
Thanks for the help nonetheless. :good:

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.

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

Hey guys, I had Lollipop 5.0 and I did stock rom flash in Nexus Root Toolkit to install 5.0.1, everything went smoothly and it started to boot, I waited for more than 20 minutes. Then I decided to do it again and it was really hard to get into fastboot, I had to disconnect the battery and try for some more time. When I finnaly get into fastboot mode I have tried reinstalling 5.0.1, installing 5.0, 4.4.4 and even Cyanogen's last nightly. With any of those I had no luck as it is stuck with boot animation.
Some googling told me about people who did fastboot oem lock and it booted up, just tried that with no luck also.
One very important thing, when I get into fastboot mode, I can only select Start in the device itself, clicking volume up or down doesn't give me any other option.
Edit: I even downgraded Nexus Root Toolkit from 1.9.9 to 1.8.2 thinking it was the problem, no luck. And tried to install Lollipop manually a couple of times. And the problem trying to get into fastboot mode keeps happening.
Thank you all in advance
And now that I tried to lock the bootloader I can't unlock it again because when I go to fastboot mode I can only press start, pressing the volume keys doesn't do anything. What can I do to unlock the bootloader ? I think I'm stuck in here because I can't do anything else without it unlocked.
Edit: It didn't work to boot the system also
I really need some help here
so your volume down key is working when you're entering bootloader mode, but after "fastboot oem unlock" command you can't choose "YES" with the same volume down key ?

All my keys are working just fine, I can easily boot into bootloader (I was doing Power + Volume Down when I should push Power + Volume Down + Volume UP) but when I get into bootloader/fastboot (I don't know which one is the proper name) I can't do anything but press the Power button, meaning that I can only choose START. When I do the fastboot oem unlock command I can't press Volume UP or Down to choose Yes.
I followed this tutorial (http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060) with no luck aswell, I finnaly got into the system, but I can't unlock the bootloader because of the Volume keys problem. I also noticed that even when I'm into the system from that tutorial, which is Jelly Bean btw I still can't use the volume keys.
Basically, phone only recognises volume keys when it's off and I press to go into bootloader or download mode.
