Assuming you have already flashed CWM, then the command would actually be fastboot reboot recovery. Not sure what but you speak of.

Yes. There sure is. If you have Rom Manager installed it can be flashed directly from there.

I'm sitting here at the command prompt with it on "erasing userdata"

It's been a couple minutes and I'm freakin' out! How long is it supposed to take? Everything flashed correctly, if I start the device now will there be an issue?

EDIT: Nevermind, just rebooted from the bootloader in the tablet and it booted fine. I'll get the OTA to 4.1.1 and that should probably fix any outstanding little issues.

Default hard brick?

I am stuck at the Google logo with a padlock and I'm pretty sure I have a hard bricked tablet. fastboot doesn't see the tablet or my computer for that mater through dmesg.

I've rebooted it countless times with vol + and vol - pushed and any combo thereof. It will only turn off completely when the battery dies because holding down the power key for 10 secs just reboots it back to the Google logo in about 5 seconds. I guess at this point I'm just waiting for Google to give me a RMA for a refund and I'll move on unless someone has any other ideas?

Pressing and holding the Volume down + Power buttons works just fine to launch the bootloader (at least for me).

No need to press (and force) the entire volume rocker button at all.

Try and press and hold just the power button for 30 seconds or so to re-boot the tablet and you should be fine and it should boot up just fine. From fastboot you cannot go into cwm recovery because of a bug.
Always pay it Forward!!!
If I helped you just hit the thanks button!!!

I'm trying to return to stock but get this message in the window from the ADB command after flashing the stock ROM:
FAILED (remote: (FileWriteFailed))

Anyone seen that before or have any ideas to fix?

I tried wiping cache/factory reset from CMW but no joy.

Thanks. Worked for me. I did get worried when i got (data transfer failure (too many links)) error when trying to flash the bootloader.

Turns out it was the USB port. I switched the ports and all was well.

But I followed the commands in side the flash-all.sh file

fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-3.34.img
fastboot reboot-bootloader
fastboot -w update image-nakasi-jrn84d.zip

Motorola Xoom > Nexus 7 >

Nuts. I tried it on many USB ports and did your commands one by one. Ended up in the same spot. It happens when writing 'userdata'...
