BEFORE YOU BEGIN

CUSTOM ROM AVAILABILITY: This is a stock rooted update (stock ROM, stock kernel), NOT a full-featured custom ROM. If you want the latest custom features implemented by Team EOS, install the appropriate Team EOS ROM (Team EOS Xoom 3G/4G MZ602 ICS ROM) (Team EOS Xoom Wi-Fi MZ604 ICS ROM); otherwise, if you want stock 4.0.3 IML77 ROM and kernel with root, continue below.

COMPATIBILITY: This update is for the US Xoom Wi-Fi MZ604 ONLY!!! If you have a Xoom 3G/4G, this procedure may break your device. If you have a non-US Xoom Wi-Fi, this procedure may break your device (though some have reported success). The update script verifies only whether the device identifies itself as a Xoom, performing NO CHECKS on the exact model of Xoom before flashing rooted stock 4.0.3 IML77 system and boot images. This means it won't stop you from flashing on a non-US or 3G/4G device; it will just flash and you're left with the mess (if any). Please proceed only if you're tech-savvy with Android and the Xoom, backed up and ready to restore in case of issues, and good at troubleshooting. Please provide feedback and corrections, and I'll update the post as quickly as I can. Thanks!

WARNING: Following this procedure may damage or permamently destroy your device. This procedure is provided with NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. Perform this procedure at your own risk.

SUMMARY

This is a modded update package (update.zip) that updates the US Xoom Wi-Fi from any ROM to stock rooted Android 4.0.3 IML77 using ClockworkMod Recovery:
  • Flashes bootloader from a previous update (3.2.1 HTK55D) to ensure integrity
  • Flashes the boot partition with rooted stock 4.0.3 boot image, stock kernel
  • Stock ICS update fixed the Bluetooth tethering issue that was introduced in 3.2
  • Stock kernel includes no extras (overclocking, etc.) from custom kernels
  • Flashes system partition with rooted stock 4.0.3 image (minus the recovery overwrite script)
  • Includes Superuser.apk 3.0.7 and su binary to enable functioning root (thanks, chainsdd)
  • Hardware SDCard continues to be read-only via documented application permissions
  • Leaves existing recovery partition intact (stock 4.0.3 update overwrites it on every reboot)
  • Leaves user data intact (note: some users updating from custom ROM's recommend wiping data/factory reset to prevent issues)

PREPARATION
PROCEDURE
  1. Backup your data
    If you have issues with this update, you may need to "wipe data/factory reset" before the system will fully boot properly. For some, simply copying the contents of the Xoom's internal storage (mostly music, pictures, videos, etc.) to their PC is enough. Others require backup of their apps, app data, etc. using more robust solutions like Titanium Backup. Backup your data according to your needs.
    .
  2. Copy/download the modded Android 4.0.3 Update package to the SDCard
    .
  3. Reboot into recovery
    1. Reboot your Xoom
    2. When the Motorola logo splash screen appears, press the Volume Down button to scroll through boot options and select "--> Android Recovery"
    3. Press the Volume Up button to enter Android recovery
  4. Wipe cache and dalvik-cache
    Note that in recovery, you use the hardware volume buttons to navigate up and down, and the power button to select. Note also that if you are coming over from a custom ROM, users suggest backing up data and doing a "wipe data/factory reset" in ClockworkMod Recovery instead.
    1. Select "wipe cache partition"
    2. Select "Yes - Wipe Cache"
    3. Select "advanced"
    4. Select "Wipe Dalvik Cache"
    5. Select "Yes - Wipe Dalvik Cache"
    6. Select "+++++Go Back+++++"
  5. Optional: Perform nandroid backup (long)
    If you have issues with this update, you may need to "wipe data/factory reset" before the system will fully boot properly. Performing a nandroid backup in ClockworkMod Recovery allows you to fully restore your device's state if you need to revert for whatever reason. Note that backing up even a bare system runs a few minutes, so this could take a very long time and require the availability of a power charger. You also need sufficient free space on your SDCard to perform the backup; the backup process does not verify required space before starting, simply failing (and wasting your time) if it runs out.
    1. Select "backup and restore"
    2. Select "Backup"
    3. Be patient

      "Backup complete!" will indicate that the update is completed.
  6. Perform update
    1. Select "install zip from sdcard"
    2. Select "choose zip from sdcard"
    3. Select the modded Android 4.0.3 update package
    4. Select "Yes - Install <filename>"

      "Install from sdcard complete." will indicate that the update is completed.
      .
    5. Select "+++++Go Back+++++"
    6. Select "reboot system now"

      New bootloader will install. The message, "Congratulation! Your bootloader was successfully upgraded" will be immediately followed by an automatic reboot.
  7. Enjoy your rooted Xoom Wi-Fi, running on Android 4.0.3 IML77!

POST-UPDATE NOTES
  • Stuck on Motorola logo/Bootloops: Users report "Wipe data/factory reset" in ClockworkMod Recovery often resolves this issue.
  • /system/build.prop errors: The updater-script mounts system and verifies that the product is a Xoom according to build.prop to prevent updating a completely different device. Some users are reporting issues with this. Until the issue is resolved in the update package, a version of the updater-script with this check removed (attached to this post) can be used:
    1. Download the attached updater-script_no-buildprop-check.txt
    2. Rename to updater-script
    3. Make a backup copy of the update package
    4. Open the update package in an archive manager (Winzip is usually a no-go; use 7zip in Windows)
    5. Navigate to /META-INF/com/google/android and replace updater-script with the one you downloaded
    6. If necessary, save the archive
    7. Follow the update procedure above

CHANGELOG
  • v03: Accommodate devices running AOSP and Chinese leaked ROM's.
  • v02: (unreleased test)
  • v01: First release, IML77; includes root, Superuser.apk, su

Great! Finally time for an update.zip with the stock ROM (not that I have a problem with EOS, I love it).

Need to have the device with the latest stock Honeycomb, right?

The update flashes entire boot and system images, rather than just patches, so this should work with your device as-is. Wiping cache and dalvik-cache is good practice, but I'm not sure whether it's needed.

Backing up your data and a wipe data/factory reset might be needed if coming from custom ROM's, as well.

Getting an error (Status 7) - installation aborted.

The zip is on the external SD Card.
The recovery is Rogue 1.3.0 CWM 5.0.2.7 based.

Ideas?

I've tested only on solarnz's CWM recovery linked in the OP, so there could be something in the package/script which Rogue doesn't like.

Also could be a botched download; does the MD5 hash match?
