fastboot for Windows/Mac/Linux: http://downloadandroidrom.com/file/tools/fastboot.zip
Stock Firmware: http://stockroms.net/file/Nexus10

For Windows, type: (XXX may depend on the stock firmware)

Code:

fastboot flash bootloader bootloader-XXX.img
fastboot reboot-bootloader
fastboot flash radio radio-XXX-XXX.img
fastboot reboot-bootloader
fastboot -w update image-XXX-XXX.zip

For Mac OSX, type: (XXX may depend on the stock firmware)

Code:

./fastboot-mac flash bootloader bootloader-XXX.img
./fastboot-mac reboot-bootloader
./fastboot-mac flash radio radio-XXX-XXX.img
./fastboot-mac reboot-bootloader
./fastboot-mac -w update image-XXX-XXX.zip

For Linux, type: (XXX may depend on the stock firmware)

Code:

./fastboot-linux flash bootloader bootloader-XXX.img
./fastboot-linux reboot-bootloader
./fastboot-linux flash radio radio-XXX-XXX.img
./fastboot-linux reboot-bootloader
./fastboot-linux -w update image-XXX-XXX.zip

*Note – If you do not have radio image, you can skip that one.
*Note for Mac/Linux – If you get permissions error, try “chmod 755 *” before doing all the commands and also try adding “sudo” in front of the commands if you still have trouble.

Try pressing power, volumeup, and volumedown, all together until you see the blue menus, once you see that, do a factory reset and reboot.

doesnt that bring me to the bootloader?

Don't we need do the following code before unroot?

Code:

fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata

c0t0d0s2 · Nov 18, 2012

if you really bricked yours as badly as I did, you might have to re format one or more partitions.

Fastboot format partitionname

Then fastboot flash partitionname imagefilename.

Don't think so, it overwrites everything so i don't think it matters.

phroghollow · Nov 19, 2012

I've fully flashed the factory image and it just sits there seemingly looping.

I've flashed the stock recovery, from Stockroms . net, the bootloader and image from the Google Developers page and it still just sits there.
Anyone have any ideas?

I've also tried erasing all partitions and then flashing again. Right now i`m willing to try anything

Why not link to the official source?

Also doesn't the official archive even come with a batch file that does all the necessary commands automatically? The latest pre-4.2 image from Google for the Nexus 7 did anyway.

The batch file I mentioned above for the N7 did this, and a guide somewhere else written before said that this was necessary due to some bug in the past (I guess something wasn't being overwritten properly).

H3g3m0n · Nov 19, 2012

Hmm, I did just the 'fastboot -w update image-mantaray-jop40c.zip' since I didn't want to mess with the bootloader, just reflash the stock rom.

Got the red triangle with !, rebooted and still got it, but after a few minutes it rebooted by itself and worked. Hopefully it was just doing some kind of first boot thing or wiping stuff.

EDIT: Also seems to have flashed over my recovery, but no biggie.

Reboots after erasing cache and then will hang on Nexus X screen forever. Any extra steps or commands to assist?

jethro1138 · Nov 20, 2012

Not working...

So I somehow bricked my N10 (all I did was flash CWM recovery, and then I couldn't mount /sdcard and it bootloops) so I tried this.

I get this:

Code:

% fastboot-mac -w update image-mantaray-jop40c.zip
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
--------------------------------------------

sending 'recovery' (5106 KB)... OKAY
writing 'recovery'... OKAY
sending 'system' (528847 KB)... ERROR: usb_write failed with status e00002be
FAILED (data transfer failure (No such file or directory))

Anyone have any ideas?...

dannymac77 · Nov 20, 2012

format?

fastboot help file doesn't show format, it is erase <partition>
Is that the correct command?

So I was kind of stuck at same spot you were I believe, where after the cache the device autorebooted and then hung on the splash screen.

I booted into the (now) stock recovery and formatted and wiped cache and it booted up fine. Hope you have the same luck.

Hatman41 · Nov 21, 2012

I did exaclty what the OP said and I am at the boot up boot image of the X that is multi color and it just loops there.

t-mizzle · Nov 21, 2012

I'm still stuck in bootloop. Entering recovery from fastboot brings up the laying android icon with the red triangle/exclamation mark.

What steps do I take next?

Press power and volume up and let go, you'll get various recovery options. Select wipe data and confirm. It'll wipe, then reboot.

Looks like today I'm more stupid than usually. I tried pressing power and volume up both in fastboot and in recovery mode, neither gave me recovery options. I know I am close but I can't nail it...
