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.

Thanks! Finally have some hope to recovering. I'll post steps I took later once I get this damn thing fixed.
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."
help?

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.

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!!
So... Anyone have any experience getting sticky bit turned off on fastboot? My phone boots to it anytime I try to reboot or do a regular boot up.

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.

Memory is fuzzy but I'm pretty sure I did it from fastboot, this happened to me about the time shabby was trying to fastboot boot boot.img and I ended up flashing it instead.

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.....

I have an interesting problem:
I have a tf300t curently running JRO03C.ww_epad-10.4.2.17-20121018
I ended up here after an unsuccessful flash with twrp. Tried to recover my back up with no joy. At this time it would only boot twrp recovery, finally flashed stock via micro sdcard and got it to boot again! Only I had no root anymore, so I tried to boot into recovery and there was none. So next I tried to boot into bootloader and when I select fastboot, the tablet says starting "starting fastboot download protocol" but after nothing else happens. ADB looses it, and it just stops right there.
The good news is that I can still use the tablet, it boots and everything works fine but I have no root. I have searched and read and searched and read. I don't know if the reflash flashes the bootloader but that didn't seam to have any effect. If anybody could point me in the right direction I would sure appriciate the help.
there is a way on the TWRP instructions using terminal when you are in system

No when I try to flash recovery it says waiting for device and nothing ever happens.
I seamed to have got it. I down graded to 10.4.2.9 and back to 13. plugged it to the computer and this time it installed drivers and that time I was able to flash recovery. I don't know what happened and it was probably something that I was doing wrong. But just incase that is what did the trick and it helps someone else, i wanted to be sure and follow up.
Hey All,
My Dad's Xoom died over the weekend - 13months after purchase so is not covered by the warranty. He was browsing a site, it came up with a "Internet is not responding - do you want to continue to wait" message and he clicked Wait - after a second the tablet knocked off. It will not come on by pressing Power and only turns on by pressing Power and Vol +
It gets past the Motorolo logo screen and the device starts the boot animation, about 20 seconds into this it freezes and reboots - this continues in a loop. It's been GEDified and was running the last OTA update 4.1.2 - no root etc.
I can get into the stock recovery and performed a factory reset - but the same thing happens. I've also tried Update From USB with an OTG cable but the screen just shows Choose a package to install and under it has /sdcard but nothing else. I have a dummy zip on both the Flash disk and SD card so it's not reading either.
I've also tried to perform update via ADB - when I select it and connect to a PC (Win 7 32bit) it tries to install drivers but I see In Computer Management that it shows under Unknown. ADB Devices returns List of devices message but nothing under it.
I've also selected the fastboot command at boot, tried fastboot devices and the command does see the Xoom.
So my questions
1) Anyone seen anything like this issue before and know how to fix it?
2) Is it best to try to reinstall the ROM? If so, how do you suggest I can see it with ADB?
3) As I have Fastboot command, could I try to install CWM and see if that sees a ZIP on the sdcard - so I can install a new ROM.
Any help much appreciated :good:
so...I've just done a fastboot oem unlock
and then tried to flash the CWM recovery using the fastboot commands - no errors, press reboot and go into Recovery but still getting Android system recovery 3e :crying:

So just to add to this, I found the stock recovery.img, boot.img, userdata.img and system.img and used the fastboot commands to send all to the motorola - all succeeded without error....still the same problem though.
I installed RSD lite and tried a few SBF files but I'm getting an INI error - off to google possible solutions to that now
My note 6 pro suddenly started doing boot loop. I tried to revive it by flashing stock firmware but nothing seems to help. It has unlocked bootloader, with TWRP installed. This is what I tried:
Put phone in fastboot mode, I do see the fastboot image.
Computer recognizes the phone. 'fastboot devices' shows correct device.
Using MI Flash tool to flash 10.3.6 global fastboot image. It takes about 160 seconds to flash all the partitions. The phone will reboot at the the end of the flash. Flash tool doesn't say "successful" though. Its status is still "flashing".
No other errors. When the phone restarts, it is still stuck in the boot loop. Interesting thing is, if I press volume + button and power button, I see TWRP flash for a quick second on the screen then boot again. Looks like the recovery image wasn't flashed properly.
Looked at the logs. Nothing strange. Also tried to run 'flash-all.bat' in a command line (not sure if we are supposed to do that), but all the fastboot flash commands look OK.
Anything else I can do to revive this phone?
