The guy in the Moto thread was clearly talking about software updates, not the 4g update.

You have to make sure you have the adb dll files in the same directory as fastboot.

I un-rooted my XOOM, ensured that SU is no longer on it and verified its no longer rooted using a terminal program. Although I placed the stockboot.img back on (a few times) and it took, for some reason I still cannot re-lock it. When I do I get the Failed to boot LNX 0x0004 / Starting RSD Mode 2 message. Any help would be greatly appreciated.

I don't think this will work without some stock software from Motorola, I'm not sure how the boot loader verifies the installed software but something, somewhere isn't matching up.

I was lurking over at the Moto support forums and the Forum Mod (and Moto employee) Matt says that they are planning on releasing the SBF files, and that unlocking your device will not preclude you from the 4G hardware upgrade.

Read through the thread. and draw your own conclusions though...

The stock software has to be released sooner rather than later, I mean the Xoom itself tells the user to go to Moto's site and get it, hopefully it won't be much longer.

For now, "we're living on the edge" lol.

adbwinapi.dll is supposed to be part of the Android sdk tools. It is not a function of the device. do a search for the file and add it to your sdk tools. You cannot run ADB without it. I still don't know why it didn't install with the SDK install.

The new SDK split adb, it's DLLs & fastboot in two tools & platform-tools, so depending on someone is using the 3.0 SDK they have to put them all together if they want to work that way.

If they don't have the DLL they need to launch the SDK manager and make sure to download the platform tools package.

How does Re-locking relate to rooting? Safe to assume that it won't lock if it either is, or was ever rooted?

Rooting shouldn't affect locking, as long as it's returned to orig state before locking.

It won't lock if you flash an image or change /system - I don't know if it verifies an md5 of some things or looks for some kind of signature that gets broken when the factory software is altered.

fastboot oem unlock give error like

FAILED (status read failed (Too many links))

I don't know any developers who have unlocked, rooted and relocked.

"I had all the stock software, and it did relock. it just would not boot back up after it relocked."

Question about Data..

The Xoom has a slot for a sim card on top of it. Does unlocking the device allow it to be used with any other carrier ? (i.e T-Mobile for example )

No, the SIM slot is only for the Verizon 4G SIM card.

Awesome, I made a thread at moto's site and asked where I can grab the authorized software to re-lock the Xoom, they said they are just working out where to host it and will update the thread when it's live:
