Thinking about unrooting Read this first!!!! ALL MODELS - Xoom Q&A, Help & Troubleshooting

**********Please Sticky**********
(MOTOROLA HAS RELEASED ALL THE IMAGES FOR ALL COUNTRY VERSIONS OF THE XOOM RECENTLY MAKING THIS A UNIVERSAL TUTORIAL AT THIS POINT)
Listen I notice recently there is a flood of issues with the xoom using different unrooting methods. I personally will say to unroot your device just bring it back to stock images. Its the safest method with the other methods if you do not know what you are doing you will find yourself sending your device to motorola for warranty repairs.
Here is a short and sweet way to unroot your xoom. by doing this you will lose your data and information so start by backing up your stuff to a computer if you have any important things on there.
if starting fastboot is on your xoom screen open up a command prompt:
0. For those who've modified their boot splash graphic with Team Eos' Splash Screen Logo Maker make sure to restore the stock Motorola boot splash FIRST as this process doesn't touch that part of the system. (Posted by Bait-Fish *Thanks for the update*)
1. Goto: http://forum.xda-developers.com/showthread.php?t=1049485 for stock USA 3G and Wifi Images
2. download the files you need
3. extract all the img's into the tools folder
4. with the command prompt open type: cd "replace with tools directory location"
5. disconnect your xoom from your computer and shut off the xoom
6. at the prompt type: fastboot oem unlock
7. it will say waiting for device
8. now plug it into your computer and reboot into fastboot by holding the down volume button and power on
9. follow the on screen instructions and agree to everything
10. your device will reboot you will get the motorola dual core window
11. force restart device by holding volume up and pressing the power button right after the device shuts off hold the down volume button and press power button
12 you should now be in fastboot mode
13. then copy each line one by one into the command window. This will allow you to go back to factory settings like you bought it from the store
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
Note: If no userdata.img file is present in your download, please issue the command:
fastboot erase userdata

Good write up. +1 for sticky if there's not something already.

whats good about this post is that it has been fully tested by me with wifi and 3G versions of the xoom with no problems reported. This method has also fixed some RSD issues. I say some because some people have flashed wrong boot images and ruined fastboot on their xooms from seeing the desktop.

wow you would think with all the issues happening with oneclick root etc you would think this would be a highly read thread. lol.

Nice guide man.

Good to have a thread like this as I was one of those one-click rooters. Unrooted, semi-bricked and learned ADB. If you're going to play with your Xoom, at least have a general idea of ADB.

Please add that this instruction (original post) is only appliable to US Xooms. Not EUs

Thanks!
Thank you so much!
I was also a clueless one-click rooter. I'd tried everything to get rooted again. This was by far the clearest and saved my hanging around waiting for a one-click unroot solution.
Cheers

your welcome enjoy your xoom.

I already upgraded to 3.1, and I unlocked it, but I can't get CWM to work, so I can't root. Can I use this method to go back to the older HC and relock, then go back to 3.1? I bricked mine before, trying to unroot and relock (I know...I know...) I've been adb'ing like crazy trying to get CWM to work, but I feel like giving up and going back to lock, stock, no barrel.

you can if you want it wont hurt the xoom which xoom do you have wifi or 3g?

I have the wifi, running 3.1, build HMJ37

if you go back to 3.0.1 you can root it, install clockwork, then upgrade to 3.1 using clockwork method. its pretty simple. within 25-30 minutes you can be running with clockwork and 3.1 rooted.

I learned my lesson! And the forum saved me.
I did the one-click root back when I got my Xoom a couple months ago, and then when I tried un-rooting and relocking to get the 3.1 update, I bricked it (you're welcome, angel) and sent it back to Motorola. When I got it back, I tried rooting the long way, but couldn't push CWM onto it. I got lots of help and tireless support from a forum member, and finally got it unlocked, rooted, CWM'd with SD support....re-lovin' the Xoom now. And I'm glad the guy that helped me out made me re-check re-download, and redo everything just to make sure we weren't missing any steps.
I love the Xoom NOW, but when I got it back from getting fixed, I was so not happy with it being unrooted! I love to toy with stuff, and this was a real learning experience. Doing all the commands, getting the stock images, re-flashing....it was very rewarding, even though it took so long to figure out how I screwed up. (can you believe it was a usb cable that wasn't working that made it so difficult! Pushed some things, but not others....changed cables, and everything worked fine.)

Nice walk through. I don't think I'll be unrooting anytime soon but its good fyi.

[GUIDE] How to fix "Failed image LNX 0x0002 / RSD mode 2

I'm sure theres a few of you out there who've bricked their Xoom in the same way I did:
Locking the boot loader after having custom rom and kernal running on it or something similar and come across an error upon boot that says
Failed image LNX 0x0002
RSD mode 2 initiated
or something to that respect
Then tried to do fastboot oem unlock, only to have the Xoom not be recognised.
The solution for me was to make a Motorola Factory cable as per guide here
For some reason, the Xoom would be instantly recognised by my computer and all fastboot commands would work, as well as RSD Lite (Did not do me any good as there is no Xoom Wifi SBF released)
That should fix the booting problem
If it still does not, follow one of the other guides on how to flash using fastboot, another rom now that you have fastboot working again!
Cheers!

So I went and bought the factory cable from the Black Hat guys, and luckily haven't had the need to use it. Any advice you'd like to give in case I need to at some point?
I guess the only advice I can give is: don't re-lock the boot loader when you have a custom rom loaded
You don't need the cable. I have recovered 4 times myself and walked many others through on irc. We all use the stock cable that came with the device.

It wouldn't recognise any fastboot commands nor the RSD Lite program for me.
But if it does, then thats good.
Merely a heads up for those who were in the same situation I was

you won't care to share how you did it? You have no idea how frustrating it is to see someone say they know how to fix something and leave it it at that.

Over the course of a few hours I was able to fix this, so I am going to write this little walkthrough for you using a rom from bwcorvus's page (CLICK HERE) and then used the guide from dirtymindedx -(CLICK HERE)
The reason it took me this long (as well as doing other things) was because I used the wrong set up to unroot my tablet. I was using the Unofficial images that are on bwcorvus's link. Because I didn't read thoroughly enough in his breakdown, I made myself look like a fool...
What you want is NOT
UNOFFICIAL STOCK IMAGES
Click to expand...
Click to collapse
because you will not be able to lock the bootloader (IF you want it to be that way, which I did, and so it gave me a 0x000004 Error, and yes i see that you are having a 0x000002 but somewhere i read this could help that.) I just wanted to get rid of Clockwork Recovery Manager cause it was not working on my 3.2 rooted tablet, and thought that because i messed up teh whole image with playing around and upgrading and seeing how i could break the image without overclocking, i thought i should actually try and make it back to stock too. With this... I needed to do these steps...
1. Upgrade the Motorola drivers while the XOOM was plugged in, so then I would be able to use the Fastboot Correctly.
2. Download the correct roms for my tablet, (Wi-Fi is mine, just grab the one that fits your version and just follow along.)
3. Upgrade my ADB from google because for soem odd reason my fastboot did not like the xoom till i did that...
4. Used the STOCK CABLE. I can Confirm that the STOCK CABLE that allows you to recharge the phones, WILL WORK for this...
5. Once the ADB was set up, I restarted it, aka Hit the red X and then loaded it back up and then closed it again, just to make sure the services were updated somewhat...
6. Opened Command prompt and navigated to the folder that help the zipfile for the fastboot flashing guide (aka dirtymindedx's guide at the top), be using CD (Drive Letter):/location/of/the/folder/that/is/unzipped
7. I then checked over the information in the folder by using dir /a and then proceeded to read through the guide
7-1. A note here... I did the fastboot erase userdata instead, because I wanted to see if it would brick it again... (sorry, I was in a fowl mood with the world last night so I was waiting for it to get bricked so i had a reason to use it as an ice scraper on my car... (not like i would really do it... just wanted a reason for justification haha)
8. ???
9. Profit
This is only to get rid of a "already slightly bricked" device... which I had done after relocking the Rom that was not official to Motorola and now, after a few updates, i now have Android 4.0.3 for the Xoom that was OTA'ed, looking to see how easy it will be to root to reload my rpg game saves that i got caught up in (hence my disappearance from the forums haha...) but I hopefully helped you out in a direction to heads towards... and as long as you don't lock the boot-loader (which someone posted about it before i did...) you should be fine with any changes to the rom after the updates... Also, you can skip steps on this too... you can just flash the image and not the recovery menu and so forth, allowing you to keep other settings that are not part associated to the rom image.
Also sorry for the insanity in my words... I have been up for a good 36 hours with a half hour nap somewhere in there...

Hey guys this is my first post here on the forums so go easy on me
So I bought this phone a couple weeks ago off of eBay. The phone was already rooted when I bought it and it is my first experience with a rooted android. I've been doing my best to learn everything I can about all the different things I can do with a rooted phone and I've learned a lot so far.
One thing that's stumping me though is that my phone will randomly just not turn back on after I lock the screen. This happens very randomly and happened to me last night which meant that my alarm didn't go off and I was late to work.
I've tried searching the forum but I can't seem to find a cause or a fix for this problem. If there is any information that I neglected to include, I apologize and will be happy to include that in another post.
Anything that y'all could do to help me would be greatly appreciated!

it's happen for me too. JB 4.1 stock rom
Maybe try another kernel. I use AIR and.have heard great things bout MATR1X and Marmite as far as stability.
I would back up your apps and do a wipe and reinstall your ROM. For back ups and system tweakage I.use Android Tuner.
I guess we should know your current set up to help you the best. Please tell us what ROM Kernel combo you ate running.and I will do my best to offer suggestions as I'm sure the test.of the community.here will.

Ok I think that the screenshot I attached is what you are asking for. If it isn't please let me know what else you need to know. Like I said earlier, I bought the phone pre-rooted so I'm not very sure how use another kernel or flash a different ROM. The whole process seems a little intimidating to me but I would be willing to try it out. I just really don't want to brick my phone because I don't know what I'm doing haha.
You're running a build based of the SDK.
Simply put. Get that crap off of your phone. Flash official stock , a custom ROM or whatever but that needs to go

Would you mind telling me what the best way to do this is, or directing me to instructions how to do it? I'm really new to this and I would hate to ruin my phone because of my inexperience.
I really appreciate the help.

Ok, thanks. Is this the latest update? Please forgive me for the complete noob questions that follow:
1. I've downloaded the file, but how do I open it and perform the update?
2. Will updating it this way cause me to lose root?
Well first off you should be posting in the Q&A section.
Use fastboot to install factory images. You can download fastboot and the driver for it from the links in my signature.
1. Download the factory image for your device and extract all the image files in it, put them in the folder where fastboot.exe is located.
2. Hold shift + right click on the folder where fastboot.exe is located, choose "Open command window here" (if you're using Windows 7)
3. Boot the phone into bootloader/fastboot mode and connect it to the computer. (While the phone is off, hold VOL+ and POWER).
4. The computer should now ask for the driver, point it to the location of the drivers you downloaded.
5. Open up the file "flash-all.sh" that you extracted along with the factory images with a text editor, it will tell you the commands you'll need to type to install the images:
fastboot flash bootloader bootloader-crespo-i9020xxlc2.img
fastboot reboot-bootloader
fastboot flash radio radio-crespo-i9020xxki1.img
fastboot reboot-bootloader
fastboot -w update image-soju-jro03l.zip
I can't remember if this process will wipe your entire internal storage or not.
Now if you want to root, try this: http://forum.xda-developers.com/showthread.php?t=1479831, although there are other ways to root.
Or you can follow these instructions to install Clockworkmod and using it to flash root: http://dottech.org/25412/how-to-root-nexus-s/.

I appreciate the extensive list of instructions you provided. I tried my best to follow them but I couldn't quite figure out what I was doing wrong. I decided to try to install a custom ROM instead and was able to install cm9 pretty easily. Will this be sufficient to remove the aforementioned problem I was having?
If your already rooted then you don't need to go through a lot of that even.though it was a good walkthrough. If you flashed a new ROM then.you have.some sort of recovery in place. As long as you do a full wipe to get the previous owners garbage off of there and then flash a new ROM like CM9 then you should be golden the new ROM will come with it's own kernel so you don't need to start learning about those until you want to.
If I may make a suggestion, give AOKP Build 4 a try the ROM you chose is good but is using old code (ICS) If you just got a new phone why not put the latest on it.
Keep me (us) posted as we the reason a lot of us belong to this forum is to offer any help we can....AOKP4 you won't regret it.

First I want to say thank you to everybody for all the help so far. :highfive: I'm still learning but I am slowly figuring all of this out.
Nexism, I would be interested in trying AOKP build 4 if you wouldn't mind explaining the easiest way to do it or point me somewhere that can explain it to me. I don't know what all goes into flashing a new ROM and I don't want to forget something that will mess up my data or my battery life.
Here is the AOKP thread. Its located in the general section.

As far as flashing goes...
Download the ROM from the above thread
Download a good app backup app (I use Android Tuner, it seems like everyone else uses Titanium Backup or ROMToolbox all have free versions only thing you'll miss is batch restore)
Back up your $hit
Boot I recovery (phone off, hold vol up while powering phone on) then scroll to recovery
(At this point opinions differ a bit) I go to mounts and storage and format the following data, cache, system, then boot then back out to the main menu and wipe all factory reset (I'm kind of a neat freak just.like to make sure I'm always starting with a clean slate)
Then install your.ROM and Gapps after a few min main recovery menu will come up
Select reboot
Go through the norm set up
Re-install backup app
Restore your apps
Then play around with all.the new features on your Nexus
Sorry if this is too basic of a walkthrough no offense if so. You can PM me if you need more detail. Good luck, happy flashing.

Awesome, thanks man.
It was exactly what I needed to know - not too basic. I flashed it and now I'm checking it out. Is there any reason I would need to use a custom kernel for anything?
No, only i u find it slow as it is now. If u want a custom kernel go for matr1x one
Sent from my Nexus S using xda app-developers app
Glad to here your Nexus is doing well.
Now that you have a good build make a backup (in recovery) so you will always have a working configuration to go back to then experiment all you want. I may get corrected on this but as long as I have a backup and access to recovery mode I know that the chances of me bricking my phone is slim to none. So I am a flash happy fool. I try everything new when it comes out.
Get comfortable with your new ROM and flashing in general and as you see a need try different stuff out.
I use a custom kernel because I use the on screen navbar and I like to turn off the hardware key backlight. You also have control over CPU min/max Frequency,governors, and I/o schedulers as well as some extra tweak options. If you're like me the more you learn the more you'll flash.
Check out NSTools it is one of the must have apps for our phones.
Again, I am available for anymore help I can.offer.

[Q] My Asus TF300T is on stock Android 4.0.3, what to do next?

The darn thing just started nagging me with an update notice that comes back every ten minutes. I read somewhere that updating is going to stop me from doing certain advanced things, so I finally got the last push to go for either CM10 or CleanRom, depending on which one gives me the most advanced and pleasant experience.
But before doing so, it's recommended to get some kind of flash info file or something from it that doesn't come out when upgraded to the latest firmware but does on the old 4.0.3. What would be the best way to go from now on?

Hi, if your tablet is still on stock 4.0.3 (ICS bootloader), I recommend doing NVflash first

If you have already updated to JB bootloader it won't work.
It doesn't say Unlocked, so I guess that's why I don't see the USB option when I try to get into Fastboot?
I'm also not able to get ADB commands recognized on my win7x64... Am I doing it wrong? What's the proper method/order of events here? Isn't there a really n00b-proof version of a guide here, or is it something I should write as soon as I get out of this mess and get it working?

Perhaps I'm not really looking in the right location, but the Asus website says I need to choose an operating system and gives me no option to choose. This way I'm not able to download the apk...
Edit:
Tried clicking the links with the tab and it started the download... Device now has an unlocked bootloader. On to the next one...
Edit2:
Ah, now I get it. Pay attention to where that Android SDK stuff is being installed. Mine got installed in the folder I unpacked the installation files! So somewhere 256 folders deep on the Desktop was the right 'adb.exe' file. Make sure the tf300_nvflashpack files are in the same directory and open the command prompt there. After that I got back to the http://androidroot.mobi/t3_nvflash/ website and entered the commands. One moment please, back in a flash!
Edit3:
Now I have 5 files in /mnt/sdcard/AndroidRoot and I uploaded them to my Dropbox. I'm guessing they are the right files...
blob.bin
blob.log
bootloader.ebt
create.bct
recovery.bct
To be sure I uploaded them all.
Copied these files into the SDK folder, along with the other zipped files for nvflash so the nvflash command works to get the other three backup files.
Edit4:
Went on following the guide and checked the video to see if I was really going the right way. Finally I have all files backed up. Goddamn what a journey, but it makes you grow a pair of balls. Now on to the next hurdle, getting a proper ROM, because stock is really getting on my nerves.
So CleanRom, CM10 or Energy ROM? Should I first upgrade to JB? Without or with the popup I'm constantly getting?
Lex,
You have alot of the same questions I do/did, and I have your original post open in another window to respond to all your questions. I'm working on writing a guide for all this stuff so this is rather helpful. If I respond to a question twice, please forgive me as I'm literally just going down the list and answering em as I read em.
In your first post, the file you're referring to is gathered via NVFlash. I haven't used NVFlash yet, but what I understand is that if you use this tool it basically backs up your ICS (4.0.3) bootloader information. The newest firmware change is to Android Jelly Bean (4.1.1) and that re-locks your bootloader. Once you go to JB, you cannot go back. So this servers as a backup (again, this is just how I interpret the information from their website. I don't know how correct my interpretations are, and have actually opened a thread to ask for clarification about this program).
For the drivers, all I did was download the android SDK and install the 'android tools' and "extra - google drivers' from the list. My laptop was just recently wiped-out so I have no prior drivers installed, nor have I connected my tablet to my computer yet (just got a replacement tablet last weekend). I didn't use the universal driver or any other add-ons. Just use the SDK, it will install drivers, and then it will detect your device. I verified this by typing "adb devices" in command prompt and it detected the serial # of my device.
Within that same post, you had some confusion about ADB. It's just an executable, and you have to use the command prompt window from whichever directory it is installed to. So once you unzip the Android SDK or wherever you installed ADB to, use the command line commands "cd directory/where/adb/is/installed" to navigate to it, or use shift + right click within that folder and it will have an option to "open command prompt here" with admin privileges. That makes life a bit easier. Other people also install their SDK to C:\android\SDK or something similar, so it's less to type.
In order to determine if your bootloader is unlocked, look at your tablet in the top left hand corner when it boots up. It will say "Device is unlocked" and list a bunch of numbers (which if I remember correctly would just be the firmware information). Your device will not be unlocked until you actually download the unlock tool from asus' website and push the file via adb to your tablet and install it. That is, you have to take a very specific, very advanced overt action to unlock it. Nothing else and no one else can do it for you nor can it be done accidentally.
Next post (#8 in the thread): You are correct that fastboot will not show unless you are unlocked. I just verified this on my not-unlocked, not-rooted new tablet, and cannot enter fastboot mode. Your ADB commands wont work if your drivers are not correctly installed.
Post #10: You have to select "Android" under the OS drop-down box to find the unlocker app. As for the location of the ADB.exe, mine was found in this subfolder within the android SDK: <whereveryouunzippedit>\Android SDK x86_64\adt-bundle-windows-x86_64\sdk\platform-tools
That folder contained the correct (and I think only) adb.exe I needed.
For your last part, I think you should try out a number of ROM's to see which you like best. I've tried all the major ones (CM9, CM10, CleanRom, Hydro, Blackbean, and some of the stock rooted/de-odexed) ROMs and used Blackbean for the longest time because of how slick it looks (all black) and how easy it is on my eyes.
Make sure you document the steps you took so you can remember them in the future. I'm working on writing a guide right now and documenting my steps to go from a stock, locked, and not-rooted tablet to a rooted unlocked and custom flash tablet.
I really hope I was able to clarify some things. I am by NO MEANS an expert but I've spent many hours experimenting and think that I wish I had someone to answer my questions when I was first learning, rather than learning by mistake.
Hopefully this helps,

Hi, I use Energy rom which I find pretty good, you will need to update to JB first as Energy, CM10 & Clean rom are all JB bootloader compliant. My tab came with JB pre installed so not sure what the best way to update is but would assume since you still have stock recovery would be with OTA update (popup notice). Here is a guide to update to JB but I think this is if you have already installed a custom recovery as it looks like you flash back to stock recovery first, thats why I think if your getting update notice and still have stock recovery, go with that.
http://forum.xda-developers.com/showthread.php?t=1845377
Once you have updated to JB stock here is a guide to install custom recovery (CWM or TWRP), root & install custom roms.
http://forum.xda-developers.com/showthread.php?t=2041627
Here is link to TWRP recovery (I had issues with CWM).

I can only click the thanks button once, but I clicked the f- out of it that one time. Although I already got to the point where my stuff is backed up, it is really good for my/our fellow adventure-seekers to have an answer to these FAQuestions. It's awesome you took the time and effort to type that much words to help out someone you don't even know. Thanks again!

Same goes for you! Tomorrow I will be trying as much ROMS as I can to see which one suits me best. Also repeating this process is the best way to learn something and since I'm unbrickable, I am going to flash the hell out of it for a few days. I'll try to post my steps and findings here so I (and perhaps others with the same trouble) can benefit from it in the future.
Also I think when you update to JB your bootloader will be locked again (new bootloader), the above guide on root, customs roms also has info and links on unlocking JB bootloader. Glad I could help, have fun :good:

It's upgrading now. Of course I forgot I lost root with the last OTA update and I forgot to make sure I rooted the thing so it was able to use the rootkeeper after upgrading to JB. I hope there is some documentation on rooting JB, because at the time this all happened root was not possible yet. It's past 1 AM over here, so I guess it's best to save this quest for later when I had some sleep.
Edit:
Just for kicks I tried 'Root Checker' and it said 'no root'. Then I saw 'Rootkeeper' was installed. Opened it up, tapped the restore button... Device rooted! Guess my memory is really failing big time... One down, # to go.
Edit2:
Installed TWRP:
Just downloaded the .blob from their website and
put it in the platform-tools folder.
Then renamed it to TWRP.blob.
Turned off tablet,
plugged in USB cable in the tablet ONLY,
hold volumeDown button,
plug into laptop holding button,
waiting...
choose USB logo,
open cmd-line in the platform-tools folder,
run command: "fastboot -i 0x0B05 flash recovery twrp.blob"
waiting...
Done. Let's see if it works...
Edit3:
At first I didn't understand how to get into TWRP (DOH!),
Hold volDown, power on, choose RCK.
Edit4:
Been having a fight with TWRP when I try to install CM10.1 (latest nightly: 20130121). Gives me an error status 7 or something...
Code:
Verifying update package...
assert failed: getprop("ro.product.device") == "tf300t" ||
getprop("ro.build.product") == "tf300t"
E:Error in /external_sdcard/CROMS/****.zip
(Status 7)
Error flashing zip ' /external_sdcard/CROMS/****.zip'
Of course, ****.zip is a long filename I didn't want to type completely here.
Will try to figure out whats wrong later today, first I'm going to try restoring the backup I made earlier, just to see how a complete backup works when the tablet is wiped back to factory settings.
Edit5:
The backup stuff is really cool! My tablet is back the way it was even though I wiped it completely!
Back to the ROM rumble... baked_tf300t_blackbean-6_jb-bl_b6.zip gives me the same error. Starting to get annoyed again... Let's try something different, CleanROM. Download is taking ages... I'm restoring again, so I can use the tablet for the rest of the day. As soon as I feel like it I will try again, for now I'm giving it 'the finger'.
Edit6:
Cleanrom is installing now. I guess CM (baked is CM based right?) was causing some trouble...
Done installing...
Wipe Cache/Dalvik...
Reboot...
Android is upgrading...
Might need to choose the small font, my screen is really clogged up with stuff. Didn't expect to keep my settings etc., thought it would be completely wiped. I'm going to restore and then reinstall with the highest DPI setting first, then I'll wander around the rom to check if I like it.
Edit7:
I think I'll stick with this one for a few days, runs fine if you ask me, maybe take the time to finally update my Galaxy Nexus to CM...

Motorola Xoom MZ640 Dev Edition?

Hello,
I am not new to android I've had two asus transformer pads currently have the one I am using with Tapatalk. My dad's friend had the same tablet I do and his screen stopped working so my dad's friend who's friend works for motorola gave him a motorola xoom to give to his friend with the tablet that wasn't working. Shortly after my bluetooth stopped on mine and he told me the other day that she has another xoom that is looking for a home asked if I'm interested.
So long story short I got a free Motorola Xoom. It's a MZ640. It's a 32 GB wi-fi only model but it's on 3.1 and can't upgrade. I checked online and the model I have should be able to upgrade to jellybean through system update. However the back of it says something like confidential motorola only and not for re-sell. Also the boot animation has a cool android wallpaper with the honeycomb boot. But when I do the Volume Up or Volume Down start up there is no recovery manager to go into it just freezes. So maybe this is a dev version of some kind of special (in a not good way) version and I am stuck unless I root. I took some pictures to try and explain it better. If anyone has seen this model before or not please let me know. If this works out and I can get jellybean on it (PC is dead..need recovery disk so can't use that) I might replace the tf300t with the xoom. The HD Sound dock looks killer. My dad's friend got it.
Also, strangely enough it came with a micro hdmi cable, car charger, and cable. There was no box..would have been interesting to see the box. If anyone needs any other number or info I have it. Just trying to figure out why I can't do jellybean update.
I have considered doing a factory reset but a little nervous if that might mess something up. Any advice is appreciated thanks guys and I hope to enjoy this Xoom.

Dude, I would have responded to this earlier had I seen it. Sorry about that.
First off, that's really cool. What you have is an MZ604 WiFi-only US Xoom that was used inside Motorola for engineering and testing. It's running an engineering build of Honeycomb 3.1, which is why you're not receiving the OTA updates. What we'll have to do is get stock production firmware onto the device. At that stage, you'll get your updates. Here's what you'll want to do:
1. Install fastboot and adb drivers on your PC. You can find instructions for that here: http://androidteen.com/setup-adb-and-fastboot-driver-with-android-sdk/
2. Reboot your Xoom into bootloader mode. To do that, turn your Xoom off. Then, power it back on. Once you see the Motorola logo, count to three at a reasonable speed and press volume down. At the upper left of the screen, you'll see some text. Press volume down until you see "fastboot mode" and press volume up.
3. Connect the Xoom to your PC via USB.
4. At a command prompt, type "fastboot devices". You should see your device listed. If you don't, then the drivers aren't installed correctly.
5. Type "fastboot oem unlock" and follow the on-screen instructions on your Xoom to unlock your bootloader. If the bootloader is already unlocked (since it's an engineering device), you will get a message in your command prompt window telling you as much. Unlocking your bootloader will wipe all data from the tablet so make sure you back up any photos, documents, music, etc. that you want before you do this!!
6. If the bootloader did need to be unlocked, it will reboot after the unlock is done. Once it reboots, perform step 2 again to get the bootloader back into fastboot mode.
7. Go to http://www.randomphantasmagoria.com/firmware/xoom/tervigon and click the link for "images" in the first row of the table (for Android 3.0.1, build HWI69). Download that file, then unzip them somewhere on your PC.
8. Go back to your command prompt and go into whatever directory you unzipped the files into.
9. Type the following commands, in order:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata userdata.img
fastboot erase cache
10. Optionally, if you want to re-lock the bootloader (unless you're going to run a custom ROM at some point, I recommend this for security purposes), type "fastboot oem lock". Follow the on-screen instructions to re-lock the bootloader. At the end of the lock process, the Xoom will reboot. Let it boot up.
11. If you choose to leave your bootloader unlocked, just type "fastboot reboot" and you'll boot up.
12. The Xoom will now boot into stock Android 3.0.1. At that point, you'll get eight separate over-the-air updates that will eventually get you all the way up to Android 4.1.2/Jelly Bean, build JZO54K.
13. Once you get the Xoom updated all the way to JZO54K, I'd do a factory reset again just to make sure everything is clear and you're starting anew.
At that point, you should be good to go. Let me know if you have any trouble.

Thank you for replying. Oh so that's why I could never update. It said verizon on it too that must explain the locked bootloader. I just recently learned about how verizon locks their bootloaders. I already did unlock the boot loader and installed recovery and tried a bunch of roms and I'm running CM 10.1 I was nervous of trying it at first but after realizing even if it's an engineering and testing tablet it's still the MZ604 and it should be similar to the others in terms of rooting and unlocking the bootloader. And fortunately I was right.
It actually came with really cool apps that I've never seen before too. I wish I backed those up before I factory reset. I tried factory resetting it initially but I lost a few of the apps and special things and it went to a Honeycomb 3.0 I believe. The one before the SD card support.
But I'm loving this xoom now that it's on CM 10.1 and using Jellybean 4.2. Even though it's tegra 2 and not as fast as my TF300T and other tablets out there the unique design, the placement for the ports and the accessories like the HD Dock make this a very unique tablet. It was never one I intended to buy so it was really cool getting it for free. My friend has one just like mine and he's not into hacking, rooting, and customization so I might be able to get the special apps and stuff that was on it from him. But even though I've never unlocked a boot loader once I figured out how to use command prompt it was really easy to do. Thank god for youtube.

The Verizon XOOM's (MZ600/MZ602) boot loader was not locked any differently than any other Xoom (example Wifi MZ604). It is/was unlockable out of the box, and Moto had the directions on their web site.
Funny, if it says Verizon on the front, I would not expect it to be a MZ604 model, unless the previous owner flashed the Wifi only Xoom (MZ604) firmware/software onto it. Does that bar code label on its back have a model or MEID on it?

Nice! I'm sure newcommers will appreciate this post a ton. Just a note, the exploit WILL work on 13a, but it WILL NOT work on 14b. If someone has the 14b firmware, they aren't screwed - simply use the KDZ restore to downgrade to either 13a or 12a. Note: when doing this, data WILL NOT be wiped - your phone will have a ton of force closes. I recommend in this case to try to get to the backup in settings and do a factory reset because the FC's will not let you get to terminal emulator to do the exploit. Factory reset to start fresh, then enable debugging, etc.

Nice, glad to help. Don't forget, your phone will likely go cray with all the force closes so you may want to just factory reset after the KDZ completes. Also, if/when you do that, after it is back to the point where you set the phone up, just get past the initial setup as quickly as possible then put the phone in airplane mode - this will keep it from trying to load the 300 apps as well as prevent Verizon's bloat crap from downloading Candcrush, garbage, [insert unwanted app here], etc. Then just enable usb debugging, install terminal emulator, and you're good to proceed with the exploit.
Personally (and I DO NOT recommend this), I've gone back and forth so many times I've lost count between stock/unroot and root. I am actually able to restore a backup from right after installing TWRP and rebooting by jumping straight into TWRP after installing TWRP image and formatting data. It has worked a number of times now.
I really only need root access for adblocking and ViperAudio.
Thanks again OP!

I just got the phone 3 days ago so a factory reset isnt gonna bother me much. And good idea on the airplane mode wouldny have thought of that.

hope you get it all working, if you want more videos adn want to keep up to date on this phone, feel free to subscribe to my chanel
I subscribed, good stuff! Thanks for putting all that together, I'm sure it will be helpful.
You should make a video or guide about debloating apps, there are plenty out there but sometimes people are really wanting to know about their specific phone model.
Subscribed. Thanks for this.

I think I could use some help. I got all the files flashed and rebooted the phone and now my screen is flickering and freaking out and the phone is constantly vibrating. everything went well through all the steps until I typed it fastboot reboot.
EDIT: Got back into fastboot and retyped typed the last few lines and I think I got that fixed. I think I'm still having a slight problem. Phone vibration wont turn off now while phone is running. ideas?
EDIT: Vibration turns off when I turn the screen off so I guess I got that semi fixed. Is that normal?
DELETED...
Is this phone unlocked by default for international use?

@LASERWOLF452 Hi. I am using an HTC 10 on Verizon. I'm thinking about buying a refurbished LG V20, and would like to know if I can just swap my HTC 10 SIM card into a V20 and be good to go on Verizon? After that I would want to root the V20 following your guide here.

Yes you can just put your Verizon Sim card from your HTC 10 in a Verizon or Unlocked V20 and all will work.

Yes it will work
After unlocking the bootloader using the dirty santa tutorial, if I reinstall KDZ stock for my cell phone, I still have the bootloader unlocked so I can later install Custom and root?
