Hiya,
After dealing with a half-bricked Xoom, I did some research on this problem and found a solution.
If in any case, you happen to get stuck on the "Motorola Dual-Core Technology"
Solution to this (For the MZ604, One-Click rooted):

*Make sure you have fastboot in the same directory as your adb for easy access*
1. Plug in your USB cord
2. Turn off your Xoom (Vol-Up + Power)
3. Boot into fastboot (Vol-Down + Power)
4. On your computer, open up a command prompt, and type the following:
Code:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot oem lock
-or-
Code:
fastboot flash boot <path to boot.img>
fastboot flash system <path to system.img>
fastboot flash recovery <path torecovery.img>
fastboot flash userdata <path userdata.img>
fastboot erase cache
fastboot oem lock
5. Reboot the Xoom
Code:
fastboot reboot
6. There you go, back to stock!
On the real though, if you can get to Fastboot (or even the Moto "Android Recovery" state), you're not THAT bricked you've got to relock and go back to out-of-box; just keep a known-good boot.img around somewhere.
You just saved my life!
Thanks for sharing OP.
I take it this method is the same for 3.1?
I hope this works. Although, I can't turn my xoom off. It also appears that my computer will not recognize my device when it is plugged in. In addition, I can't turn off my Xoom? It just reboots... so I can't enter fastboot mode.
I just posted this in a new thread.

I tried reverting back to stock using the "one click" root/unroot tool that was the first to come out for the Xoom.
Anyway, I tried the unroot process and everything was going fine, until something occurred. Now, it tries to boot up and says at the Moto Dual Core Technology screen, "Failed to boot LNX 0x0004 // Starting RSD mode 2".

You can still enter fastboot if you xoom won't shut off. Just hold the appropria oncete buttons as it reboot. Happened to me last night upgrading to 3.1. It. Wouldn't shut down at all. Once I got into fastboot my computer saw it and I was able to fix
Honestly, I almost went through all of this last night when my WIFI Xoom got stuck in a boot loop.
However, I noticed that when my recovery went to flash the new 3.1 file, I felt like it didn't take as long as it should have. The file was the right size and all and it even said that everything installed successfully, but it just kept boot looping regardless of trying over and over. So I went ahead and re-downloaded the 3.1 file and repeated the steps to flash it and everything worked.
So, before you spend a whole lot of time restoring your Xoom, simply re-download the files and try it one more time. It worked for me.

hmmm... I'm in fastboot supposedly and tried to flash boot.img but it seems to be stuck at <waiting for device>
This happen to anyone else?
After search seems like a driver issue, but I have installed the drivers... I was previous rooted, so I know I have the drivers. Just to be sure, I ran the MotoHelper again. I don't understand. It's just seeing my device on the "Starting Fastboot protocol support."

Yes. How did I fix it? I returned the xoom and had a new one two days later.
If the screen says something like "Entering RSD 2" then you're boned. The xoom won't be recognized in either the current state or in fastboot state by the computer, so no amount of commands will help. Even having the stock images doesn't help with that. Even RSDLite can't see the xoom in that state.
There have been several reports of people just being honest to Motorola and them fixing the device under the warranty.
Hmm honesty. I'll give it a shot.
Sent from my ADR6300 using XDA App
Is the final OEM lock necessary? It's quite a pain as your userdata gets wiped if you unlock it...
I was stuck on bootloop, with unrecognised device, through adb was able to get back into clockwork recovery somehow at first boot, think twice down volume? Could be wrong.
I was able tto rreflash zip 3.1 over thet top again.
sry if this is different and unhelpful, bu imagine things are pretty desperate if you are considering returning the device

You're not boned at all. I had that happen to me so I just got back into fastboot, downloaded the files in the OP put ADB, Fastboot and the adb extensions into the file I downloaded then ran the commands and got me XOOM back up and running fine.

You were likely in RSD 3, which is recognized by the computer. RSD 2 means adb and fastboot cannot see the device at all, so no flashing images is possible.
There's several states that all look very similar. Because some success was had with one doesn't mean it works for all. Motorola recognizes and is telling users that, in this state, the device needs to be sent back to them.
Can someone help us wifi xoom. Im stuck on the motorola screen and have a lil experience. I can fast boot reboot/fastboot device and it work but cant get the files from the hwi69 to fastboot on to it. I think im entering the commands wrong. Any advice would be appreciated

Very good info to get into fastboot protocol:
Much thanks for the info. Worked like a champ. On an updated 3.2.1 XOOM I did an unlock, re-locked the wrong way, soft bricked, unbricked back to locked state. Finally followed your steps applied stock files and XOOM is re-locked and stock rocking back at 3.01. I needed to do all this to make sure I could get it back to stock in case it goes back to BB in 2 weeks. I was lucky enough to find one at a BB just not sure if I'll keep it. I plan on trying out some roms plus I heard Motorola is planning on doing an ICS push to the XOOM. ICS is very nice. It runs great on my unlocked Verizon G-Nex.. Again Thanks..
This post not only saved my half-bricked non-rooted Xoom, but also let me flash it from the Singapore firmware (bought if from Amazon, don't ask lol) to the regular USA firmware so that I can properly root it!
Thank you so very much!!

Can you get into fastboot? You might want to try reflashing your boot and system partitions. I believe it was BeagleBoy that grabbed them off of a stock Xoom Wi-Fi. You're already unlocked I imagine. Should let you flash those right back in and start fresh.
This guy got out of a semi-brick by doing something similar.

If you can get into fastboot, you should be fine. Don't panic just yet.
Try reflashing the stock boot.img and system.img files through fastboot. I did it a few days ago http://forum.xda-developers.com/showpost.php?p=12832155&postcount=33
You can find boot.img and system.img for stock wifi xoom on the OP of that thread.
Failing that try the semi bricked solution.
I hope you solve your problem.

Power off the device.
Then hold Volume Down and hold Power on at the same time.
it shows "Starting Fastboot protocol support" and stopped there. what this mean? =(
that means you should be able to get it running again.
follow the first message in this thread:
http://forum.xda-developers.com/showthread.php?t=1010568
probably from the stuck at 'dual core technology' bit...
but I think this is what you should follow:
adb reboot bootloader
fastboot flash boot boot.img
fastboot reboot
adb remount
adb push bcm4329.ko /system/lib/modules/bcm4329.ko
adb push tun.ko /system/lib/modules/tun.ko
adb push scsi_wait_scan.ko /system/lib/modules/scsi_wait_scan.ko
adb push cifs.ko /system/lib/modules/cifs.ko
adb push vold.fstab /system/etc/vold.fstab
adb reboot
you might also want to pick up the stock wifi images:
http://forum.xda-developers.com/showthread.php?t=1017398
and flash them using:
fastboot flash system system.img
fastboot flash recovery recovery.img
(you've already flashed boot.img above).

If you're lucky, your computer will connect and typing in "fastboot devices" will show an entry for your Xoom. You do not need to start with ADB if you're already in fastboot mode.
From there, flash the boot.img for the proper Xoom version you have. You may also want to flash the system.img as well.
From there, simply try to reboot using "fastboot reboot". Make sure your Xoom starts up. If it does, you're pretty much good to go. I'd root from there manually.

That's not necessarily true. My PC can no longer detect my Xoom in any way whether or not it says "Starting Fastboot protocol support" or "Starting RSD mode 2". I can't get it to say anything else.
I used to be able to get into fastboot. That's how I bricked my Xoom... By trying to oem lock it with what I was hoping to be clean boot, system and recovery image files for the wifi.
Now, I can't even get back in to oem unlock or flash. RSD lite doesn't pick it up in RSD mode 2, but does pick up my old RAZR phone.

What sort of computer do you have? Can you copy and paste what you see when you type "fastboot devices"?
Copy and paste from your command prompt (or Linux terminal) and let's see what you've got.
ok. will report once tried. thx very much =)
Okay. If you can get into fastboot (check by "fastboot devices"), all you should need to do are these two commands if you're connected:
Code:
fastboot flash boot boot.img
fastboot flash boot system.img
fastboot reboot
That should get you close to stock first.

Mine did that for a short while after I screwed up a flash, I reflashed boot and while running tossed the adb command to get into fastboot and then left it properly. Haven't seen it since.

To clarify... Flash boot from recovery, while that is running adb reboot bootloader? If that is the case I have a different set of problems to "boot", I can't get my pc to recognize the phone while in recovery. Everything else is recognized, even reinstalled drivers to be certain, pc doesn't even try to install a driver for recovery. Tried both TWRP & CWM.

Okay, this will probably help you...while your device is in Sticky Bit Factory Fastboot, open up a command prompt and connect to your device (given you know how to do so in your folder containing your fastboot app and drivers). Then type "fastboot oem fb_mode_clear" This command will allow your device to boot into system normally. Problem is (I think) when a failed flash occurs sometimes it sets your device in that mode and the above command clears it. Another way to manually place a device in the same state you described is to enter this command using fastboot: fastboot oem fb_mode_set. I believe that is how RSD Lite automatically reboots your device into factory fastboot mode after flashing partitions (.mbn) on your system so that it may resume flashing the boot, recovery, and system images, etc. Let me know if it helps.....

A few days ago I tried getting my phone to s-off using the "[how to] manually achieve s-off,simunlock,supercid for Inspire 4g/DHD" guide on the Android forums. (Sorry, I can't post direct links.)
I got to the part where I was supposed to type in "fastboot flash boot boot.img" to the command line but I accidentally skipped that part and typed in "fastboot boot recovery recovery.img". I stopped everything and tried to start over but when I turned my phone back on I was stuck in a boot loop. Going to hboot and trying to choose Recovery or Factory Reset only results in more boot looping.
I've tried putting PD98IMG.zip on the SD card and booting it, but it only reads it and says "Parsing..." before doing nothing. Attempting to enter recovery mode after this makes it enter the boot loop again.
I've also tried using the HTC Sense and RUU from AT&T on my computer to fix the issue. My phone can connect to my PC after choosing fastboot from the hboot menu. The RUU can see the device and it starts recovering it, as my phone shows a black background with HTC on it. But the RUU stops after trying to update the signature saying "The ROM Update Utility cannot update your Android phone. Please get the correct ROM Update Utility and try again." I am 99% positive I am using the correct RUU.
I've searched high and low on the internet for a similar situation, but everyone else seems to have their problems solved using either of these steps. Thanks for any help.
Without knowing what you did (since you haven't given us a step-by-step and can't post links), we don't know how to help.
Sorry about that. I'll try to explain what I did the best I can.
Before using the guide, I managed to root my phone and used it for a few days, so everything was fine then. I later decided to s-off it so I could flash a custom ROM to it. Using the guide I mentioned above, I created a mini-adb directory in my C: drive with the ace-tools.zip that I downloaded. Using the command line I copied my stock boot image, though to where I do not know. (I feel like a fool for doing all this without being sure of what I was doing exactly. I deserve what came to me.) Then, using the command line I made my SD card a gold card. After that I changed the "misc version" (?) to allow installation of the downgrade firmware, and then relocked the boot loader and booted back into fastboot. Then I flashed the downgrade software and unlocked it again. It's here that my phone was supposed to be unable to boot, and I was supposed to flash the boot image but skipped that step.
Now I'm unsure of what I have to do, and I only want to get my device working again.
I wish I could post the link to the exact topic, but since I can't I guess you'd have to search the topic name to see exactly what the directions were trying to get me to do.
Thanks again.
Can you boot the phone into fastboot and flash the boot.img from fastboot?
No, with the PD98IMG.zip file it simply says "Parsing..." and stops there. With any other boot image it doesn't acknowledge it at all. Even though the computer makes the sound that it's connected to the device when it's in fastboot, adb can't recognize that's it's there in the command line.

Wait. What? Not PD98IMG.zip from hboot. Extract the boot.img and flash from fastboot, not adb.
Ah, thanks for the clarification. I'm supposed to extract the boot.img to the SD card and enter fastboot on my phone, correct? Because I've just done so and nothing happened. I have the options Bootloader, Reboot, Reboot Bootloader, and Power Down, and the Bootloader option only takes me back to the hboot screen.
Sorry if I've misunderstood you.

No, the boot.img needs to be on your computer. Your phone needs to be in fastboot mode. From the folder where the boot.img is saved,
Code:
fastboot flash boot boot.img
I can't use the command prompt to connect with the device because it can't see it. I always get an "error: device not found" instead.
Is your phone in fastboot mode?
Yes. It's odd: the RUU software identifies it and knows it's there, but can't actually fix the issue. The command prompt just doesn't notice it at all.

So you're booting into hboot, navigating to fastboot with the volume buttons, and selecting it with the power button? What does fastboot devices say?
I'm assuming by "fastboot devices" you mean what it says in the command prompt.
...Well what do you know, it recognized it. I was typing in "adb devices" instead of "fastboot devices". So it can recognize it after all.
I'm assuming I have to load the boot.img now?
Hey hey, wa-hey!
That was much easier than I thought it would be! A simple "fastboot flash boot boot.img" followed by a fastboot flash recovery recovery.img" using some image files I made before messing everything up did the trick. Thank god I did so.
Everything's back to normal; my phone escaped the boot loop. And last but not least, I don't have to buy a new phone.
Thanks so much for helping me out, even if it was clearing a few things up for me. I appreciate it.

You're welcome. You could also have fastboot flashed any custom recovery image, flashed a ROM from recovery, and fastboot flashed that ROM's boot.img. So you weren't too badly off.

This means you are in fastboot. try running 'fastboot devices' on the computer the xoom is connected to, to see if your device is listed
you should see something like below if your xoom is communicating over the fastboot protocol correctly

Have been jumping through many hoops. I found an old backup.zip that after many tries was able to run. After that I was able to use fastboot in the normal way. My xoom is up and running again. Waiting for goo.im to come back so I can get the lastest ROM.
Thanks for your reply:laugh:
My xoom is doing all the same things, except I have no recovery. Flashing it through fastboot suceeds but has no effect. Recovery is required to use an update.zip right?

Thought I had i done, but no:crying:
The Xoom is now completely Stock with the last update installed. The Xoom is working normally, with one major exception.
I cannot start fastboot or recovery This meas I can not root my xoom :crying::crying::crying:
As soon as I try to start fastboot the USB connection is lost and the Xoom shows a dead android on its back with the red triangle on top.
Any suggestions:fingers-crossed:
Purchased an Lg Gpad 7 Wifi tablet (v400) 2 weeks ago. Came with preinstalled Lollipop android so i couldnt install a recovery rom to flash any other custom roms. Downgraded to Kitkat version following the instructions on Xda forums and succesfully installed Twrp. When i installed Cyanogenmod 12.1 through Twrp i got stuck in fastboot screen.
Any suggestions and / or solutions would be greatly appreciated.
I had a similar problem.. Only mine was stuck at the bootloader. Go in TWRP and repair /data and other partitions. My data partition gave me an error since F2FS is a little flaky and some ROMs corrupted it (claimed they supported it). I would recommend erasing the system, cache and data partition if you can't get into TWRP.
The problem is i cant get out of fastboot whatever i try. It says start on bootloader but the tablet just restarts on an empty screen doing nothing.

if you have an sd card, try removing that, then reboot.
if that doesnt work, try entering fastboot command, fastboot continue
Tried without sdcard and i get the same fastboot screen.
How can i give any commands? The only options i have are Restart Bootloader / Restart / Power off. Tried restarting bootloader but i get nothing in return tablet just stays on with nothing on screen.

you said it was stuck on fastboot, if thats the case, install any needed drivers on your pc, connect device to it, open a terminal in the fastboot dir (after you go get fastboot), then try those commands i gave. you could also try, fastboot reboot dont think i mentioned that before.

Did as you said but every command i gave gives me an error message in adb terminal. There are new lines in fastboot menu in tablet now. Bottom two are SECURE BOOT - enabled & LOCK STATE - locked.

hmm, ok, im guessing it would have said that normally, when not broken. all the command does is try to release it past where its stuck. it doesnt actually flash, lock, unlock, or change anything.
imo, this seems good, because now we know fastboot is working.
i own lg devices, but not your specific device. i would hate to give you some bad advice and make your tablet broken more, but if it were me in this situation, i would try to flash the factory KK firmware you used to downgrade with odin or however you did it. hopefully, that will clean everything up and let it boot properly.
if for whatever reason you cant do that, we could try extracting the factory file, and just flashing recovery and system, those should be the only things that got changed putting on twrp and cm normally.
Sorry, I have the serious proplem wtih my LG pad V400, I rooted it and using <LG Flash Tool 2014> with <V40010c_00.kdz> to downgrate the firmware but their is error then my LG pad stuck in fastboot menu as with just turn off, restart and restart bootloader. if i seclect one one them the tablet just logged again the fastboot menu
it stuck on the fastboot menu and i cannot do nay think with it. I can restart with factory restore mode but when select yes to restore, it will restart and log in fastboot menu again.
I downloaded adb and fastboot program and put in one folder <Minimal ADB and Fastboot> in C:\Program Files (x86)\Minimal ADB and Fastboot
I dont have recovery image so i download file <cm-13.0-20160421-NIGHTLY-v400-recovery.img> form your link to download TWRP file
move it to folder of fastboot programe and changed its name to <recovery.img>
I turn on the tablet and it waited at fastboot menu
when i run the command <fasboot flash recovery recovery.img> and they said some thing wrong like in picture
please help me
