##PLEASE NOTE##
These files are from Motorola's Development site and I take no liability with anything that happens with your device if something goes wrong.

DO NOT ATTEMPT TO FLASH THIS FILE ON ANYTHING BUT THE VERIZON WIRELESS MOTOROLA XOOM Z600 (3G MODEL) OR YOU WILL HAVE A SHINEY PAPER WEIGHT!!!!

You're going to need to have the Android SDK installed. You can download it here:
ANDROID SDK - DOWNLOAD

XOOM Firmware Downloads:
[3G|MZ600-HRI66]
[4G|MZ602-HLK75D]

Unzip the files in MZ600_HRI66.zip and move or copy them to the /platform-tools folder in your SDK folder.

Connect your Xoom to your computer. Type:

Code:
adb reboot bootloader

Wait for it to reboot into the bootloader.

Type the following commands, waiting for each to finish before continuing:

Code:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache

You've now successfully flashed your Xoom back to stock. Now it's time to relock the device. Type


Code:
fastboot oem lock

wait for the menu
then press the volume-down button.
Then press the volume up button.

It'll take a minute or so, then reboot. You're now completely back to stock and ready for the update.

So the HRI66 is the latest version on the Motorola site? I really need to get a grasp of their version numbers.


EDIT:

Never mind looks like HRI66 is the latest version Thanks anyway.

i was thinking that with the change to the bootloader in the 3.1 update we couldn't use previous versions img's. But I am glad we can return to stock and get this 4G update!

I'm following all those steps directly. Once I type in adb reboot bootloader, it says starting Fastboot protocol support. Once I try to type any other command it says not recognized in adb. Any ideas?

Could someone help me,

After the rebooting device I got this massage :
Failed to boot LNX 0x0004
Starting RSD mode 2

Then stuck on Motorola logo. I can't enter the recovery mode.

What should I do ?

My Xoom is H.6.1-38-9 International version

This is what I was afraid of..... try searching the error you are getting. Not many options on how to fix.

i am curious about the LNX 0x0004 error. I know it comes from trying to relock with non-factory img's but what exactly does that mean? I am curious what actually causes the device to soft brick.

Kinda having the same issue as dchurch... "adb reboot bootloader" reboots Xoom to the "M" logo with "Starting Fastboot protocol support," but I can't continue with nay further commands. My computer no longer recognizes the presence of my Xoom and my Xoom doesn't progress past this screen. I can boot it normally with no problem. I've extracted all of the necessary files into my platform tools folder with adb.. any input?

You can try manually going into fastboot as well... there are two ways to do this:

No matter what, power off the Xoom. Then, 1) Power on the Xoom and as soon as you see it turn on (within a second or two of the power on), press the Volume Down button, which kicks it into Fastboot. 2) If you miss the 1st couple of seconds and press Volume Down after 3-5 seconds, it will say "Android Recovery." You can then press Volume Down until you get to Fastboot, then press Volume Up.

My guess is that you have a different issue, something to do with your Fastboot image. Not sure if booting the Xoom into the OS and connecting with USB Debugging on will work or not to flash the files, perhaps maybe just the boot.img?

I also believe that when the Xoom says "Starting Fastboot protocol support", it is in fastboot mode and you can send the fastboot commands to the Xoom. If your PC does not show the Xoom as a device in your PC's Device manager, then you will probably need to load new/correct drivers onto your PC.

    Dead link...

    No, the link is not dead.

    You need to register an account at Motodev to download it.
