[Xoom Q&A, Help & Troubleshooting] NoP_Compiler:
Ok. EOS6-RECOVERY installed correctly. There are a couple of mistakes and some missing info in the "tutorial", so I'm going to change it to help future users:

I finally did it under Windows because almost all tutorials in Internet explain all the possible problems that you can find in Windows, and it's a "too risky" task for me to "experiment" by myself.

PART 1 .- HOW TO INSTALL EOS6 RECOVERY:

Originally quoted from wesamothman:

First, download the above ROM and GAPPs and put them onto your xoom external SD card. Put them in a folder called /sources/ of your external sd card.

- Get the Motorola USB drivers to your laptop: http://developer.motorola.com/docstools/USB_Drivers/

- Get the Android SDK to your laptop: http://developer.android.com/sdk/index.html

- GAPPS: http://goo.im/devs/teameos/roms/eos3/gapps/gapps-jb-20120726-eos-signed.zip

- ROM: http://goo.im/devs/teameos/roms/eos3/nightlies/wingray/ ; get the latest one...

And the most important:

- Recovery Image: http://goo.im/devs/teameos/recoveries/wingray/eos-recovery-r6.img

Check that the md5sum of this file is correct and matches with the one provided in the download page. This is the most important file because it will allow to install the CWM recovery system and it's CRITICAL that the file is not corrupted.

Steps:

a.- Install in your PC the lastest JavaSE JDK from Oracle's website.

b.- Install in yout PC Android SDK, open Windows' cmd, enter the android-sdk folder and run:

tools\android.bat update sdk

Now select "Android SDK Tools", "Android SDK platform-tools", and Extras/"Google USB Driver". Click on "Install packages".

c.- Enable USB debugging in the XOOM (in settings, development).

d.- Install the Motorola USB drivers for your laptop (32 or 64 bits, check it in the Windows system properties).

e.- Plug the Xoom to your laptop.

f.- Execute cmd and enter the android-sdk/platform-tools folder.

Run "adb devices", if you get an empty "List of devices attached", then you must enter the control-panel -> devices and "Fix problem with device" over the MZ60x device. After a While, Windows will fix it and "adb devices" will show a message like:

List of devices attached

037887sda897xz device

(the digits string will vary according to your device)

NO NEED TO DO THIS:

NO -> 1. Power off your XOOM device.

NO -> 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.

Because the first command show after this lines: (adb reboot bootloader) won't work while in fastboot. Only "fastboot" commands work in fastboot mode. If you try that command in fastboot mode, it will say "Error: device not found".

So just, with your xoom working under the Android OS, do:

adb reboot bootloader

With the above, you'll enter fastboot mode without needing to press any key in the startup.

Now your Xoom will show the Motorola logo and the words "Fastboot protocol...". If you need to stop now for any reason, you can abandon this mode safely and reboot the tablet with "Power+VolUP+VolDown" for a few seconds.

But let's continue.... If you now do:

fastboot devices

You should get a string like

List of devices attached

037887sda897xz fastboot

If you don't see that string (and you see and error about device not found), you have to "fix/repair" the usb drivers again in the Windows ControlPanel / Devices. Now you'll see a "FASTBOOT" device instead of the MZ60x you repaired before (that's why we have to repair/fix again the device, because WIndows see it as a different device while in fastboot mode).

After repairing it, unplug and plug the USB cable (still in fastboot mode) and repeat the command:

fastboot devices

Now it will work and you'll see the device recognized by "fastboot"

Issue the following command to unlock the Xoom (you'll void the warranty):

fastboot oem unlock

Follow the Xoom's onscreen instructions to unlock the bootloader. You have to use VolDown to move through options and VolUP to accept an option.

The xoom will reboot and your old android OS will show, but now with a factory reset. Select language, time, etc and enable again USB debugging and execute in the PC:

adb reboot bootloader

(to start again the tablet in fastboot mode)

Now copy the file eos-recovery-r6.img to the android-sdk/platform-tools/ folder and execute:

fastboot flash recovery eos-recovery-r6.img

You will see something like:

C:\Users\sromero\Desktop\android-sdk-windows\platform-tools>
fastboot flash recovery eos-recovery-r6.img
sending 'recovery' (4114 KB)...
OKAY [ 0.499s]
writing 'recovery'...
OKAY [ 1.014s]
finished. total time: 1.529s

Check in the xoom's screen that the file was correctly written and execute:

fastboot reboot

You xoom will start again in Android OS mode. Execute:

adb reboot recovery

And you'll start the nice EOS Recovery (based on Clockworld Mod) recovery system.

You can also do it manually by powering on the Xoom and when the motorola logo appears, wait 3 seconds and press VolUp.

Now, you have your device unlocked and recovery installed. Now, you are SAFE because you can do nandroid backups and restores and can put any ROM in your system and go back with a backup or flash another different rom.
