[Nook Color Q&A, Help & Troubleshooting] pman555:
Yes, I searched, but nothing I found seemed similar to my situation.

Here is the timeline of events:

Rooted my nook with autonooter a long time ago.

Decided last weekend that I wanted to install CM7.

Installed Rom Manager, CWM, etc. Then installed CM7.

Decided that I wanted to bring my nook back to stock so I could check out the 1.2 update.

Restored it back to stock using Option #1 in this thread: http://xdaforums.com/showthread.php?t=914690&highlight=reset+stock

It worked fine the past few days.

Then last night I decided I would try this: http://xdaforums.com/showthread.php?t=1045018

I burned the image to the SDcard, expanded the partition in order to be able to use the SDcard for storage. Placed the sdcard in my nook.

It wouldnt boot at all. The screen refused to turn on.

I tried it many different ways, holding the 'n' button while turning it on, holding the volume buttons, etc.

Then i took the sdcard out of the nook and tried booting it.

It still wouldnt turn on. The screen simply would not turn on. Finally after a few tries, it did turn on. So I shut it off for the night and thought I'd try again today.

I tried to turn it on again today (without the sdcard in the nook) and it will not turn on. I've tried it about 25 times. Holding the power button for many different time intervals.

And yes, its charged. It was fully charged last night.

Any idea what I can do here??
[Nook Color Q&A, Help & Troubleshooting] RASTAVIPER:
Connect it with power cable (no matter if its charged) and try to turn it on by Power button.

Then restore it to original rom.
[Nook Color Q&A, Help & Troubleshooting] pman555:
Unfortunately, I'm at work and dont have my power cable with me.

I have a compatible USB cable that I can plug into the computer, but I already tried that and it didnt work.

Also, the nook should be on the stock rom already. It was on stock 1.2 before I tried the dualboot sd card last night.
[Nook Color Q&A, Help & Troubleshooting] pman555:
OK, so I just tried turning it on for the 50th time today, and for some reason it worked.

It was not plugged into anything, I didnt do anything differently.

Just held the power button.

Anyone have any idea what could be causing this?

My nook is stock 1.2.
[Nook Color Q&A, Help & Troubleshooting] jlscarpa:
I had a similar problem, and I thought mine was bricked. I used WinImage to create a ClockworkMod boot microSD card. Holding the power button for ten seconds performs a manual power down, release, then hold it for another three to five seconds. It will boot to ClockworkMod Recovery.

Now, I had installed HC update RC3 from a week ago, and it worked just fine. The dev releases a hybrid with the Asus Eee Pad Transformer this week, and I tried updating to it. It caused my Nook screen to not turn on just like yours.

Once in ClockworkMod, I can reinstall the zip files, but it still won't turn the screen on unless in Recovery. When I try to restore my backup of CM7, it says there is an "MD5 error." Not sure what that is or how to fix. Maybe you can help me?
[Nook Color Q&A, Help & Troubleshooting] pman555:
Well it sounds like our problems are very different. However, I have some experience with your problem with my thunderbolt.

When I got an MD5 error, it meant that there was something wrong with the name of my backup. Does your backup have spaces in the name? Or did you change the name of it after creating it?

Unfortunately, I was never able to recover the backup with the MD5 error.

If you can get into recovery, it sounds like you should be able to restore your nook to stock via this thread: http://xdaforums.com/showthread.php?t=914690&highlight=reset+stock

If I were you, I would return my nook to stock and start over.

NICE! Will be trying this out shortly.

trying it now.... will give feedback
[Xoom Android Development] Sparticuz:
Can someone confirm the filesize and md5 of the update zip file? (the actual update.zip, not the updater-script)

Do I need to be using the stock kernal before I start?

here's the official update link for wifi xoom:

[Xoom Android Development] le_pere_noel:
just one quick question why is it US only ? don't you think it should work on wifi only euro too ?
[Xoom Android Development] publicanimal:
Yes, but the official update won't flash in ClockwordMod Recovery unless it is modified, like the one in the OP of this thread. Posting the official version on this thread just adds to the confusion.
[Xoom Android Development] tony710:
All he posted in the OP was a modified script, you still need to get the update.zip from Google.

The Google server is much much faster than the 3rd party download sites too.
[Xoom Android Development] stachre:
Only because I don't have a test device. I'll update the post.
[Xoom Android Development] tony710:
Just got done with this procedure, and it works perfectly.

I'm rooted on 3.1 on my WiFi Xoom.

Thanks OP!
[Xoom Android Development] Sparticuz:

Ah my bad, I only saw the .zip at the end of the filename
[Xoom Android Development] Legend28469:
Anyone know if this works in Canada?
[Xoom Android Development] mbroeders:
So, maybe a stupid question, but did you have Tiamat kernel installed? Just wondering if that makes a difference. Thanks!

-edit- plus, will this wipe all userdata??
[Xoom Android Development] moosamm:
were do we find a boot.img that enables adb remount?
[Xoom Android Development] dowenprs:
Thanks man! Can't wait to give this a try when I get home!

One general question though, what program do you guys use to edit the update.zip?

Thanks in advance for the help fellas!

Peace

Dan
[Xoom Android Development] tony710:
Yeah, I had Tiamat installed and all my userdata stayed.

I'm currently trying to see if I can flash the latest Tiamet back to see what happens.
[Xoom Android Development] tony710:
I used 7z to edit the zip file
[Xoom Android Development] tony710:
Tiamat by brd allows the remount command
[Xoom Android Development] dowenprs:
Solid, thanks for the reply and help!

Peace

Dan
[Xoom Android Development] stiffspliff:
does this also flash the new bootloader?
[Xoom Android Development] tony710:
Yes it does.

Also, FYI:

After I flashed Tiamat got stuck at the Dual Core screen, I kind of figured it would because Tiamat flashes the old boot.img but figured it was worth a try :p

Thanks OP!
[Xoom Android Development] cat2115:
Hi OP,

Thanks for the guide but i get confused. When you say flash "stock" system.img

and "stock" boot.img, is that mean the one I download from "stock Xoom WiFi MZ604 HWI69 images from Motorola"?

Is this how it goes:

1. copy stock system.img, stock boot.img, su, and superuser.apk to platform folder

2. flash stock system.img

3. reconfigure superuser

4. flash stock boot.img

5. perform modified update.zip

- in the stock update.zip i had delete stock "update-script" and replace with modified "updater-script"

- do i need to rename the modified "updater-script" to "update-script"?

correct?

Will this unlock and root?
[Xoom Android Development] mbroeders:
I'm stuck at the adb remount. I've got root access and have tiamat 1.4.1 installed. However, when i type adb remount, I get the "remount failed: operation not permitted option". Also, when trying the other commands to configure superuser, I get messages saying "read-only file system". Anyone knows what to do?

-edit- nevermind, installed 1.4.0 and everything works fine. Thanks for the guide!!
[Xoom Android Development] odyseus:
Excellent Work!! This works a treat on my UK WiFi Xoom (flashed with the Motorola img files)

All the best

Ody

The only change I made was to copy the modified update.zip file to my SDcard right at the start, omitting all the card mounting stuff in CW Recovery, ie I just went to install zip file from SDcard...
[Xoom Android Development] RMarkwald:
OP - You may want to add:

Copy the su and Superuser.apk to your SDK Tools folder. I forgot to do that, and was like oh s#%@! After moving them over, worked great!

I had Tiamat 1.4.1 and unlocked/rooted, downloaded stock images as described, put everything into SDK Tools folder and went smoothly!
[Xoom Android Development] xMemphisx:
Got it working for myself as well! Thank you!

Also, here's a Mediafire link to the corrected update.zip file that I used (so you don't have to use WinRAR to repackage the updater-script file):

[Xoom Android Development] cat2115:
Hi, I'm currently on Tiamat 1.4.1. So all I need to do is copy stock system.img, stock boot.img, su, Superuser.apk to SDK Tools folder and I'm good to go?

[Xoom Android Development] funkatiko:
Guys i need help here...i did everything posted before including going back to stock, fix superuser, substitute the update-script but when i attempt to apply the patch while the verification system process it says tro me : ASSERT FAILED: apply_patch_check ("EMMC:/dev/block/platform/sdhci-tegra.3/by-name/boot:8388608:ba6a886948e07917531c202fc13351c4bf1e4b2e:8388608:e4b3f37e6baa87942585f14c94a4048c64487f")

Any ideas?Am i doing something wrong??? Thanks!
[Xoom Android Development] AndrewNeo:
Thanks, worked great for me! Windows didn't want to see the USB storage, so I told recovery to mount /sdcard and used adb push instead, but it worked just fine otherwise.
[Xoom Android Development] RMarkwald:
I'm not seeing it.
[Xoom Android Development] stachre:
That's the pre-update check failing on the boot partition. Did you flash the stock boot.img?
[Xoom Android Development] xMemphisx:
No movie rentals for me either
[Xoom Android Development] teenfaces:
movies

I don't think the player shows up unless you select a movie in a file explorer. I found all kinds of movies by searching for movies in the online marketplace. I still prefer mobo player with accelerated hardware support for 1080 avi files..
[Xoom Android Development] woost12:
Awesome write up. Anyway to get the same written procedures for the 3G model?
[Xoom Android Development] tony710:
I would assume it would be the same, just make sure to download the 3G versions of all the files needed.
[Xoom Android Development] stachre:
Yes.

Sounds good so far. I've updated the guide since your post, though, so definitely give it another read through.

I think all my references include "updater-script", which is the correct spelling. There should be no "update-script". If I missed anything, please do show me where, and I'll gitter fixed. :)

Thanks!
[Xoom Android Development] stachre:
I don't have a 3G model; are you volunteering to test for me? I can send you an edited updater-script for 3G if you wanna be a guinea pig. :D

[Xoom Android Development] jlaw904:
Is overclocking possible or will we need to wait for a custom 3.1 compatible kernel?
[Xoom Android Development] tony710:
We'll need an kernel first. You can still use SetCPU to underclock and set up profiles it just maxes out at 1ghz on stock
[Xoom Android Development] XSJoJo:
Hi there,

The procedure went well till the last step:

When I try to apply the update from sdcard it tell's me the following:

E:Can't mount /sdcard/update.zip

Installation aborted.

Any Ideas how to fix this? Pushed the update.zip on the sdcard with adb.

Thanks in advance
[Xoom Android Development] B Dizzle:
Worked like a charm! Nice work man. Now we need a compatible kernel.:D
[Xoom Android Development] 05GT:
Thanks to the OP.. worked like a charm!
[Xoom Android Development] SlCKB0Y:
+1... anyone?
[Xoom Android Development] umbra6:
You have to mount the SD card in recovery. The SD card should show up as a removable disk in Windows. Then copy the update.zip to the card with Windows Explorer. After that unmount the card and apply the update.

I can verify that this guide did indeed work on my US Wifi Xoom. Running 3.1 goodness right now :). Thanks OP!
[Xoom Android Development] funkatiko:
You were right, thanks.
[Xoom Android Development] umbra6:
Also as a note, you will lose access to the SD card on the Xoom since the stock kernel is loaded on this. Thats fine with me for now since the browser and OS is a ton snappier now. As long as I can still access the SD card in recovery I'm good.
[Xoom Android Development] equid0x:
Just did this... works a treat! Like other have said be sure to mount /sdcard first in Clockwork before applying the update.zip
[Xoom Android Development] djsaad1:
Worked great for me but I don't see googles new movies app? Does anyone else have it?
[Xoom Android Development] stachre:
I was testing all night (no sleep til Brooklyn! :D) and I never saw this, so I'm not exactly sure what's going on.

Is your SDCard mounted in recovery? Check "mounts and storage" and see if the option "mount /sdcard" is available. If so, mount it and retry the update. EDIT: I updated the guide to include this.

Otherwise, please detail the last two or three steps you took before you got this error.
[Xoom Android Development] SlCKB0Y:
Sorry for the stupid question, but is the update.zip file to be physically located on an sd card or can it just be put under /sdcard in the filesystem with no physical sdcard in the system?
[Xoom Android Development] mutiny:
OP should be getting about a gazillion "Thanks" just from today.

WiFi US Xoom here running rooted 3.1. This guide is super easy. This can be made into a "one-click" for the uber noobs, but I really encourage the newbies to learn and read up. It comes handy to know how to do stuff manually when **** hits the fan.
[Xoom Android Development] XSJoJo:
Thanks for the help,

I just figured out that i had to insert a Real SD-Card into the slot, since it didn't work with the internal one.

Thanks for the help, it's working fine now :) Hello 3.1 :) great Help
[Xoom Android Development] umbra6:
Eeek...I think you have to have an SD card in order for Clockwork to work. The first post may have to be edited to include this intel...
[Xoom Android Development] mr_delphi:
boot loop...

what should i do now?

after flashing system.img

reboot

now boot loop

uk wifi

update: ok, at least i am able to get to fastboot...everything back to stock now...

I just figured out this by experimenting, lol

vol up + power = reboot

before the animation shows up, vol down + power = fastboot
[Xoom Android Development] stachre:
Excellent catch! Updated!
[Xoom Android Development] SlCKB0Y:
Crap. I rooted long ago so my tiamat version is 1.16 so no sdcard support. I have installed clockwork tonight and it is working (i just cant really do much with it!) .

I didn't do any of the above steps yet, i just wanted to see if i can mount /sdcard in recovery, which i clearly cant as it needs an actual card to be in there.

Next step I guess is to update my kernel and get the sdcard support then proceed with the how-to.

I'm really new to this... how do i got about updating my kernel to a new version under the current circumstances?
[Xoom Android Development] B Dizzle:
I am clearly on 3.1 now but am not seeing the music sync under my google account in the settings menu like the 3G users have reported. Anyone else seeing this?
[Xoom Android Development] snobrdinrtiste:
can i still root if i already am on 3.1?

Hey guys,

Need a lil help here...I don't wanna do anything stupid to brick my xoom...so i thought I run this by you all...

Last night I reverted back to stock from the Moto Images and then right away...I got the 3.1 OTA update...

Now this morning I see this tut on how to update to 3.1... Stupid me... should have waited... but anyways, i'm trying to root the darn thing and was wondering ... If I fastboot flash the boot.img image that allows for adb remount... would that eff everything up? or can I go and flash it to my 3.1 xoom and then adb push the su and superuser.apk?
[Xoom Android Development] SlCKB0Y:
As far as i know (which clearly isnt too much), this update only works on US wifi only.

:(
[Xoom Android Development] stachre:
Recovery's access to the SDCard is independent of your kernel. As long as the SDCard is formatted, you should be good to go.
[Xoom Android Development] The_Tech_Ninja:
Works like a charm!

Thanks!

3.1 on US WIFI!
[Xoom Android Development] djsaad1:
I dont see the music sync, or have the new videos app.
[Xoom Android Development] kall00:
Just updated two wifi's in the office. Both successful.
[Xoom Android Development] RMarkwald:
That's what I did. I downloaded Motorola's stock WIFI image zip, but everything in that zip into SDK Tools, along with su and Superuser.apk, and you should be good to go.
[Xoom Android Development] stachre:
You need adb mount to push su and Superuser.apk.

You need the custom boot.img to do the adb mount.

You need a 3.0 system.img to run with the custom boot.img (until devs release a 3.1 compatible custom boot.img)

Note that I had issues in my testing early this morning going back from 3.1 to 3.0. Lots of force closes until i nuked my user data. Hope you have better luck.
[Xoom Android Development] mr_delphi:
imo, uk xoom is the same as us xoom

someone above mentioned his uk xoom works this way
[Xoom Android Development] hm1b:
After upgrading to 3.1, do I still have option of the external sdCard or it will be gone when operating the Honeycomb? I have Tiamat 1.4.0 kernal installed
[Xoom Android Development] umbra6:
Try this (I cant guarantee this is going to work):

Download the latest kernel .img and put it in your adb directory

1). Boot Xoom holding power up + power

2). Fire up adb on your pc

3). type "flash_image boot kernel.img" where kernel.img is the filename of the kernel image you want to flash

Also if you already have clockwork recovery on your Xoom you should be able to access the SD card once you put one in....
[Xoom Android Development] SlCKB0Y:
Of course it is...geez its 3am where i am im not thinking properly. Thanks!

It is being recognised now so I will begin your how-to.
[Xoom Android Development] KerryG:
Had an issue where my main machine I used to root with would no longer see the XOOM via adb. Tried it on laptop and it worked fine. Had a couple quirky issues getting the SD card to show up but eventually got it and was good from there. Thanks guys!
[Xoom Android Development] cat2115:
the last step: Perform Update

Can I use Rom Manager?
[Xoom Android Development] dascope:
This guide worked great here!

Only had one issue, it wouldn't boot up all the way, kept getting that honeycomb loading animation over and over and over... was able to use adb, so copied the few files I wanted to backup, then flashed the stock userdata.img file, and it finally loaded up properly. With Honeycomb 3.1! So I'm all set now, but for those who get that endless bootup honeycomb animation, this is one way to fix it...

Have a Canadian Xoom Wifi here.
[Xoom Android Development] umbra6:
Don't think so. Since youll have the stock kernel on the Xoom at that point, the OS won't see the SD card. Of course there is one sure way to find out...try it :).
[Xoom Android Development] snobrdinrtiste:
yeah i figured as much... i think i'll just sit tight until the devs come out with a root solution for 3.1

thanks
[Xoom Android Development] hm1b:
I guess that was the answer to my Q....Thank you
[Xoom Android Development] SlCKB0Y:
Brilliant! got it all working. Thank you very much!
[Xoom Android Development] Vanhoud:
Step E should be reversed. If it says "Unmount SD" then you should select it to unmount it before trying to use the update.zip. Other than that great post! Worked for my Wifi Xoom :)
[Xoom Android Development] gerald410:

Also to note i just pulled the SD card out of the Xoom put it in my PC copied over the update.zip file rebooted into recovery and just flashed updated.zip didn't do any mounting in cwr flashed with no problems. man the ui seems a lot faster now too. the lag in browser is gone as well which is nice.
[Xoom Android Development] balto:
I also have the Canadian Xoom Wifi and I am stuck in the boot animation over and over, I have preformed all the steps in the OP but I am still stuck. At what point did you flash the userdata.img after you did the upgrade or before?

Edit:

I figured it out, flashed as the last step, it is now working.

Could someone please post a link to the stock images?
[Xoom Android Development] validoption:
I've not done this yet, but I'd assume that the custom kernel gets overwritten with stock once the stock system.img is flashed, no? If so, then external sdcard is gone until BRD creates a kernel for 3.1.

[Xoom Android Development] gpstar:
works good on my canadian wifi xoom.

Just to note as indicated previously by others, for people who are running non usa xoom images, like canadian or euro ones, etc, you have to you have to flash the stock userdata.img to fix the endless boot cycle after you flashed the boot.img

fastboot flash userdata userdata.img

Note you will loose all your personal data on your xoom, as this basically wipes the system. Then reboot make sure you enable usb debugging after so you can adb reboot into the recovery to finish the upgrade.

also note that doing the upgrade in this thread sets your xoom into USA version, so you loose all the extra language support.
[Xoom Android Development] le_pere_noel:
Ok that's the reason I had my problem.

Just one smal question is it possible to activate the cifs module with the 3.1 ?
[Xoom Android Development] jlaw904:
