Yes, Let me clarify should you need to:
Definitely root your xoom and upgrade to custom ROM of ICS from Nightlites EOS team. Rooting and upgrading to this custom ROM, wingray for your device MZ604 is pretty fast and easy. will help you if you need to.
• Your custom ROM will be: Eos-wingray-102.zip. This is the latest ROM released on May 3rd. Very stable and everything works with it. No issues found.

To summarize:
First, download the above ROM and GAPPs and put them onto your xoom internal and external SD card.
To download:
• Get the Motorola USB drivers:

• Get the Android SDK:

• Recovery Image:

• ROM: Your custom ROM will be: Eos-wingray-102.zip. This is the latest ROM released on May 3rd. Very stable and everything works with it.

Steps:
1. Power off your XOOM device.
2. Press and hold the volume down button while pressing the power button at the same time. Note: Even if your xoom starts again, just keep the button pressed until you see "Starting fastboot protocol" on the screen.
3. Connect Xoom to your computer via USB.
4. Open a ‘Command Prompt’ or ‘Terminal’ window on your computer in your sdk/tools folder.
5. If your device is not already unlocked, type:
i. “adb reboot bootloader”
ii. “fastboot oem unlock”
iii. “fastboot reboot”
6. If your device is already unlocked, and to flash another recovery, type:
i. “adb reboot bootloader”
ii. “fastboot flash recovery eos-recovery-r6.img”
iii. “fastboot reboot”
Now, you have your device unlocked and recovery installed.
Reboot your xoom, you will still have your old ROM.
To flash the other ROM downloaded above,
1. Boot into recovery by:
i. As soon as you hit the reboot command, you should see a Motorola logo appear. Wait 3 seconds and tap the Volume down button and the words Android Recovery should appear on the screen. When you see that, tap the Volume up button and you’ll boot into recovery.
2. From within Recovery, perform wipe data, wipe cache, and go to advanced, wipe dalvik cache and battery stats. Don't worry, if the ROM and GAPPs are deleted, which should not be the case, you will have them on your external sd card
3. In recovery, navigate to install zip from sdcard > choose zip from sd card and select the EOS ROM you copied to the root of the SD card. Once the files are flashed, DO NOT reboot afterwards. Hold on.
4. Again, from Recovery, choose install zip from sdcard > choose zip from sd card and select the GAPPs you copied to the root of the SD card.
Then hit reboot system now. It will take 2 - 3 minutes for the first reboot. Setup your google account. and you are good to go.
Later reboots will be much faster (around 40 - 50 seconds).
Advice: purchase Startup Manager from the market. Remove unwanted user programs from the startup. That will boost the boot time of your xoom. and don't remove superuser or superSU.
To have better battery life, from the market buy JuiceDefender ultimate. configure it as aggressive. don't worry, it is ok. This will give you around 2 hours of extra battery life than the promised 10 hours. Keep that in the startup.
You may need after that to install terminal emulator from the market if not already installed by the ROM to check if you have root permissions. Just type "su -"
you will be prompted with superuser check. Click allow. and then type "id"
You will see your id is root.
Should you require further details or assistance, please let me know. And enjoy the best rom customized ever for your device
Best Thanks to TEAM EOS for the great ROMs they provide.
After you are done with all that, let me know and will explain to you how to work with the pre-installed gooManager in the new ROM. It will make your life much easier to upgrade to future releases of your ROM.
NOTE: don't forget to hit the thanks button if you feel kind to
