[Xoom Q&A, Help & Troubleshooting] HuckFinn:
This thread is an attempt to help out the Tiamat Developers by answering the frequently asked questions in one consolidated thread. This thread should also be helpful to those who either cannot use the search feature or are having a hard time figuring out the correct search terms to find what they are looking for. If you have suggestions or added questions/answers feel free to reply and I will update the OP.

NOTE: I am not a developer. All of the information in this thread is from other members who have helped me out or information I found in the XDA forums. I do not take credit for any of the great work that has been done on this ROM and I will point back to the original answer when possible. I am only trying to help lessen the burden on the developers so they can spend more time getting us the best features. Hopefully you find this helpful as well.

I've flashed this ROM and now I get update notifications. Should I accept the update? How do I stop these notifications?

No, you should never accept an OTA upgrade when using any custom ROM/Kernel. This could result in severe problems. Your best bet is to be patient and give the developers time to react. If the update is worthwhile I am sure they will roll it out pretty quickly.

To get rid of the notifications flash Mod pack 3 as noted here.

OK I made the mistake of accepting the OTA update and now my Xoom won't boot. What can I do?

From this thread.

With this ROM certain websites don't load correctly or I can't get to the mobile version of a site.

This ROM by default sets the User Agent String to "desktop". If you want to revert to the stock settings flash either Mod pack 1 or 2 depending which version of Moray you are running. Look here.

I flashed this ROM and now when I click links in email or my file explorer the screen just dims and nothing happens.

This is a bug in Android 3.2 and not specific to this ROM. To solve this, simply ensure auto-rotate is enabled and rotate the device from landscape to portrait and back to landscape. The app chooser window should appear allowing you to choose which app to open the selected file.

I just flashed this ROM and the speed is amazing, so I OC'd it to 1.7GHz cuz I want more and I am now stuck in a boot loop. This worked for others why not me?

The Xoom was only specified to run at 1.0 GHz, anything beyond that is a gift. Due to part-to-part variation not everyone's Xoom will be stable at the same speed. Yes some people are able to run at 1.7 GHz, but many cannot. For your specific Xoom try out the various speeds, but do NOT click "Set on Boot". This way if it crashes it will revert back to stock speed and you will be able to boot. Once you are satisfied with a speed then feel free to enable "Set on Boot". Before you do so I would suggest making a nandroid backup so you can restore just in case.

How do you get out of this boot-loop? The only way I know of is to boot into recovery and restore a nandroid backup if you have one or perform a full wipe if you do not.

I updated to the latest CWM and I cannot find the zip card or I get "get error: E:failed to mount /sdcard (No such file or directory)."

Latest is not always the best, for the Xoom you need to either use ClockworkMod 3.2.0.0 (R4C) or CMW Rogue Recovery v1.1.1

After flashing this ROM the Motorola icon gets distorted during boot up, is that a problem?

Basically it is not a problem. This kernel has a patch provided by NVidia which causes the distortion during boot. It does not cause any problems after it boots.

Is there a way to get the stock WiFi and Battery icons?

Yes

How do I boot into recovery without ADB or my PC attached?

There are a couple methods.

1) The latest Tiamat ROM includes this if you press and hold the power button. Just pick what you want and hit OK.

2) Download and install "Quick Boot" from the market. It gives you the above options as well as others when you run the app.

3) Turn the Xoom on, wait ~2 seconds after your see the Dual Core logo, then press the volume down key. In the upper left corner it should say "Android Recovery", then press the volume up key to select it.

How do I get started? Any good guides?

There are several guides that are pretty good. The best one I have found and personally used is here.

The Xoom Heaven thread found here is also a good place to start for all sorts of information.

If you have another question please feel free to post to this thread. If you are having a problem or have a question it is likely that someone else along the lines will have the same problem or question. I will continue to update this OP with the list of F.A.Q.s.
