I recently bought a US Xoom MZ604 and had trouble flashing it initially. I came to a realization that the newer models of Xoom reinstalls the Stock Recovery after you flash a custom Recovery (eg. CWM, Rogue Recovery etc). This is uber frustrating for newer Xoom owners, especially those who are new to the flashing community, simply because you don not know exactly what's going on.
Also, I could not find any proper, full and updated guide to flashing your Xoom. So i decided to take the initiative to do so.
WARNING: I DO NOT TAKE ANY RESPONSIBILITY IF YOUR XOOM TURNS INTO A USELESS BRICK. BY FOLLOWING THIS GUIDE, YOU WILL VOID YOUR XOOM WARRANTY WITH MOTOROLA. YOU HAVE BEEN WARNED TO EXERCISE CAUTION WHILE FOLLOWING THIS GUIDE. STRICTLY FOLLOW THIS GUIDE AND I ASSURE YOU, NOTHING WOULD GO WRONG.
In order to follow this guide, you need fundamental knowledge of ADB and Fastboot for Android. Search around the forum for this knowledge.
STEP 1: Obtaining Required Materials
a.) Download the latest version of Android SDK from HERE and install it into your the root of your C: drive.
b.) Download the latest version of Java SE from HERE and install.
c.) Download and Install the latest version of Motorola USB Drivers from HERE.
STEP 2: Unlocking your Bootloader
What is a Bootloader?
In literal terms, bootloader is code that is executed before any Operating System starts to run. The concept of bootloaders is universal to virtually all Operating systems that inculcates operating systems on your PC, laptop, smartphones, and other such devices. Bootloaders basically package the instructions to boot operating system kernel and most of them also have their own debugging or modification environment. As the bootloader kicks off before any piece of software on your device, it makes it extremely processor specific and every motherboard has it’s own bootloader.

2.) On your PC, open up File Explorer and Browse to:
4.) Command Prompt will open up. Type the following command:
adb reboot bootloader
6.) Type the following command into the Command Prompt to unlock your bootloader:
fastboot oem unlock
8.) Once selected, your Xoom will now unlock and format itself, meaning, all data will be cleared and you will back to a factory rest.
9.) Reboot your Xoom with the following command:
STEP 3: Rooting your Xoom
1.) Download the latest version of "Universal Xoom Root" from this thread. Place the .ZIP file into the root of your SD card.
2. Download this version of "ClockworkMod Recovery - Modified for Motorola Xoom" and place it into this directory:
2.) With your Xoom still connected to your PC, type the following commands into Command Prompt (open up using the same method as STEP 1) to install your new Recovery.
adb reboot bootloader
fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
Then 3 seconds after you see the Motorola logo, hit volume down. You should now see "Android Recovery" in the top left corner. Hit volume up to boot into recovery. If you miss this window and somehow end up booting your Xoom normally, repeat from STEP 3, section 2 onwards again. DO NOT CLOSE THE COMMAND PROMPT WINDOW.
4.)To root your Xoom, please perform the following:
"install zip from sdcard" -> "Choose zip from sdcard", then select the Xoom-Universal-Root.zip file you downloaded.
Note: use the volume buttons to navigate and the power button to select
5.) Now you have to rename the 2 notorious files, that reinstall your Stock Recovery over CWM, into a format that is unreadable by the bootloader. In the already opened Command Prompt, type the following commands:
adb shell mv /system/recovery-from-boot.p /system/recovery-from-boot.p.old
adb shell mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.old
To test whether the root and flashing of CWM has been successful, type the following into your command prompt:
adb reboot recovery
I would like to thank the Xoom Android community for your valuable commitment to into Xoom Android Development. Without you guys, the Xoom wouldn't feel much powerful in terms of usage. Also, I'd like to extend my gratitude to okantomi for his help when I first started out.
Those those experienced users of Xoom, please kindly help the newbies like me answer their questions in this thread. Could I also request the mods to sticky this thread for reference.
NOTE: For users who would like to revert to the original recovery, type the following into ADB: (tip provided by wontoniii)
adb shell mv /system/recovery-from-boot.p.old /system/recovery-from-boot.p
adb shell mv /system/etc/install-recovery.sh.old /system/etc/install-recovery.sh
