[Q] Rooting 2.3.3

Hi All,
I'm trying to root my Nexus S and this is my first time rooting an android phone. I'm following instructions at
http://forum.xda-developers.com/showthread.php?t=895545
But it is failing when i try to do a recovery of superuser zip file. instead i'm displayed an android with exclamatory mark.
I'm on Android 2.3.3, build GRI40.
Please help me in rooting my phone.

Did you try posting in the thread instead of starting a new one?

Yes it said i don't have permission to post on that thread

Google Modaco and Superboot. That's what worked for me. You just need to figure out how to do the "fastboot oem unlock" command.

The android and "!" exclamation sounds like you're still on the stock recovery.
Get back into fastboot mode on the phone (pull battery if needed), then go back to the step that has you "fastboot flash recovery recovery.img" and start over from there.
You have to get Clockwork recovery onto the phone to be able to flash the superuser zip.

Are you sure? I got superuser through Superboot, and got Clockwork after rooting.

Thanks...superboot from modaco forum worked me. This is cool just one click and im rooted. On to next step...flashing the rom

The guy wasn't trying the superboot method, he was trying a different method that requires clockwork to flash the superuser zip file, so yes, in the context of the question he posted, I am not only sure, I am very sure.
If the guy is having trouble getting into clockwork recovery, using superboot isn't going to help him out beyond getting su and superuser.apk installed, since superboot doesn't replace the stock recovery with clockwork. Without clockwork he's not going to be able to use recovery to get much done in terms of flashing custom roms or updates.

You still need to master the step in the other method that flashes clockwork onto the phone. If you can't get that done, no custom roms; if you could get that done, no reason to use superboot.
Be aware, superboot replaces your kernel with a modded one; probably not a big deal, but something to consider if you wanted a stock kernel. For example, one version of superboot for 2.3.3 uses the 2.3.2 color tables.

Root Xoom Wifi 3.1

Is there a method out yet? I'm looking at the one click root method but it's unclear if it works with the 3.1 Wifi US model. I don't want to be a guinea pig so if anyone knows please let me know. Majority wins.

Please wait until a new boot image has been made for the wifi model

Ok cool thanks. I'll burn some time downloading more apps and stuff.

Just follow those steps.

I had a stock wifi xoom and got my 3.1 update OTA yesterday and install it. If I do this method, does it take my xoom back to 3.0.1, then back to 3.1? Do I loose my data?

Jase33 helped me with this a little while ago, in order to root you will have to go back to 3.0.1.
In doing so you will lose data. You can use BRD's method to get 3.1 fully rooted.

If you have a WIFI-only Xoom you can also attain root using my method:
http://forum.xda-developers.com/showthread.php?p=13712556
First your Xoom has to be unlocked, then all you need to do is install a custom recovery and flash my MZ604_3.1_ROOT_update.zip file.
Unlocking your XOOM:
Follow the first step here: http://forum.xda-developers.com/showthread.php?t=1010568
Once your unlocked all you need to do is flash a custom recovery (I recommend this one: http://forum.xda-developers.com/showthread.php?t=1074979
and flash my MZ604_3.1_ROOT_update.zip file from within your new recovery.
By the way the file needs to be on an external SD card so you'll need one of those as well.
As far as working one-click methods, that I am unsure of.

Thanks, I personally wasn't looking for a one-click, cant speak for the OP though. So, in order to install a customer recovery we don't have to be rooted already?

One more, I see your method mentions having the original boot image. Will that be necessary if you're never rooted running 3.1. Thanks again.

Will this wipe my data?

Folks, be careful with this. Dont rush into something you may regret. And last I checked you need root existing for cwm to work properly. So if you are on HC 3.1 stock, be glad you got the OTA and wait for something to be posted and tested. Too many posts are titled "HELP!!!! PLEASE!!! my Xoom is bricked or stuck or whatever"

I'm just going to wait for the One-Click to come out. I know how to root and adb but I'm leaving today from NJ to NC for my brothers graduation. I don't want to get started in something that I won't be able to finish. Hopefully when I come back the one click will be out.

[Q][SOLVED] Upgrading from Canadian Wifi 3.0.1 to US Wifi 3.1

Hi All!
I would like to convert my completely stock non-rooted Canadian Wifi Xoom (MZ604) into a US xoom so that I can install the 3.1 software on it, as well as root, sdcard capable kernel, and CWM recovery.
Unfortunately, after reading many many of the threads here, I am totally confused as to what order to follow. Here is what I'm thinking, but please please correct me if I am wrong:
[steps removed]
Is that it? I feel like I'm missing something or that I may brick my device since it is not a US-rom that I am using as a base.
Thanks for the help!
[update 28th May]: The steps that I followed to get 3.1 with CWM & Tiamat on my Canadian Xoom are below, in post #7.

1. boot the device into fastboot and unlock it. Erase all cache and wipe the userdata.
2. Flash the complete US 3.0.1 HWI69 ROM. (yes, do this)
2.1 Root the 3.0.1 Rom
3. Install CWM recovery from http://forum.xda-developers.com/show....php?t=1074979 using the fastboot method.
4. Install the 3.1 update from http://forum.xda-developers.com/show....php?t=1074609, skipping the 3G step since I only have Wifi.
5. Install Tiamat 1.4.2 from http://forum.xda-developers.com/showthread.php?t=978013. (update to one of the newest kernels)
6. Install International Language Pack from http://forum.xda-developers.com/show....php?t=1083612 to get back all languages from 3.0.1 ROM.

For your suggested step "2.1 Root the 3.0.1 Rom", would the thread at http://forum.xda-developers.com/showthread.php?t=1010568 be the suggested strategy?

that will work

So did you do all that you said ? Did it work ?
i'm about to do my candian wifi xoom !
Thanks

I was hesitant to do that since I am reading a lot of bricking stories lately, I have a canadian MZ604 stock too, will do the same if you succeed!

Alright folks, It's been a few days now since I've updated my Xoom, so here's the process that I used. Note that it is different from the steps I listed in the original post:
1. Unlock the device via fastboot. Instructions here. DO NOT RE-LOCK EVER!!
2. Flash the Official & complete US 3.0.1 HWI69 ROM. Links here. Every time I tried to download the "does not require login" version from mediafire I got a corrupted zip, so instead I downloaded from the Motorola developer site (with instructions) here.
3. Once the 3.0.1 Rom was up and running, and I had an internet connection, I got the OTA notification for the 3.1 update and installed it. It took about 10 minutes to notify me once I had connection, probably because it had to download it before notifying me. After the install and reboot process, I had a stock 3.1 install, but still didn't have sdcard access. So, I kept going.
4. Install CWM 3.0.2.8 recovery, using the fastboot method. Instructions here.
Once CWM was installed and I had the ability to backup the rom, I immediately made a backup before EACH of the following steps was performed. I know it is overkill to make that many backups, but I wanted to be sure I wasn't going to screw up my device at any given step and have to start over again.
5. Root the 3.1 rom from here. After rooting I had sdcard access within honeycomb at /sdcard/external.
6. Installed Tiamat 1.4.2 kernel. Instructions here.
7. Installed the Language Pack from here, but when I rebooted the system it went into a loop on the purple animated honeycomb logo. So, I rebooted into recovery again, and did a "wipe data / factory reset" - this allowed my machine to reboot normally, but I had to reconfigure all my settings and reinstall all my apps.
So as of right now I'm on 3.1 HMJ37, rooted, with CWM recovery, Tiamat kernel, and have international languages! It's great!!
Mike.

Thanks for the detailed info... I flashed the complete US 3.0.1 ROM on my canadian xoom and got the 3.1 OTA update as well. So now my canadian wifi xoom is on US 3.1 !
I will not root it for now since i don't really need the external SDcard for now.

When you say Flash US 3.0.1 ...do you have steps to do that? I'm just wondering how to do it...since I don't have a functional SD Card I guess its not the flash update.zip method...
Can't wait to be running the US rom and not care for motorola Canada anymore!!!

Just saw that the steps to flash the rom are on moto website! Sorry!

How to flash
I've spent hours on this and I guess I must be stupid, but I can NOT figure out how to flash a ROM! I've tried the ADB commands, I've download the ROM manager, etc, etc, etc...I cannot find any instructions on how to do this! It must be very simple because every time I look for instructions, they always just say "flash the ROM" like it's nothing. But HOW???
Very frustrating...there appears to be no single place that outlines all the steps in one place - it takes a dozen web pages to do the simplest things...
I also want to update my Canadian ROM to a US ROM. I'm unlocked, I'm running Tiamat 1.3.0 but I don't know what to do now...?
It seems as though having an external micro SD card supported is a prerequisite, but I cannot figure out how to get that to work either. The frustrating part of all this is that I do (Windows) computer support - I'm not new to technology in any way, but I have seldom been more frustrated than this trying to find one set of clear instructions...!
HELP!
Thanks.

after flashing using the instructions on post number 7 with the HRI39 bin images and fastboot my tablet doesnt boot. it just sits at the motorla logo for ages and ages and ages...
do I maybe have to wait like an hour or something?

Converted my MZ604 Singapore version to US & OTA update to 3.1
I managed to reflash International images to US and OTA update to 3.1 using a mod microUSB cable. I didn't need to root my xoom to do it rather a hardwired method.

2. Flash the Official & complete US 3.0.1 HWI69 ROM. Links here. Every time I tried to download the "does not require login" version from mediafire I got a corrupted zip, so instead I downloaded from the Motorola developer site (with instructions) here.

Ok, hook your xoom up to your computer and open up a command line. Then CD to your tools directory of the android sdk and input these commands.
adb reboot fastboot
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
fastboot reboot
And your good to go..... continue from the next step just be carefully to input the commands exactly, and for the love of Pete DONT UNPLUG your xoom while flashing

And do NOT relock!!

I will be attempting this in the next day or so but had a few newbie questions (coming over from the apple world):
1) For step two, the img files all come from HWI69.zip?
2) For step four, do I want to do it with CWM or without? Is there more risk to one vs. the other?
3) For step six, to boot into recovery mode, is the following sequence correct?
Turn your XOOM off
Press Power to turn your XOOM back on
When the Motorola Dual Core boot screen appears tap Volume Down repeatedly until "Android Recovery" is displayed
Press Volume Up to enter Recovery

1) Correct - also, I know I keep saying this, but on the Moto site instructions for flashing they tell you to relock. Don't!!
2) I used the fastboot method (without). Make sure to download the img and not the zip.
3) I tend to wait on the Moto logo for about 3 secs then just press down once. Then up once you get the recovery option. Never fails.
Good luck.

Great. Thanks for the quick response. One additional question. This procedure seems a fair bit shorter in length than this one:
http://forum.xda-developers.com/showthread.php?t=1073884
Is there a reason? Is there a place where I can read some sort of a beginner's guide to rooting so I can understand the steps I am going to be following better?
Thanks again.

After flashing the images from the HRI39 zip from MotoDEV it did not work. My device wont boot. I have reflashed back to stock for the Canadian Xoom and that works just fine again, But I'd like to know why it wont boot with the other one since MANY people have done it without a problem.
I have executed these commands:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
Then manual reboot... simply sits at the motorola logo.
This is my 3rd attempt. Still nothing.
If anyone can provide some solid support it would be greatly appreciated.

Not sure, as i don't have that model, but i would recommend posting in Q&A.

Xoom bricked

Hi there everyone,
I have a huge problem. Last night i bricked my xoom. I was following a tutorial on this forum. and after unlocking the bootloader it told to flash a file called boot.img after doing so and typing fastboot reboot, the device wouldnt start behind the motorola logo. i tried allot of thing and also did flash some other stock android 4.0.4 boot.img files now with the last one mentioned i managed to get the xoom (wifi) to boot a little further. because the ripple movie with the motorola logo is shown. but it stucks at that movie.
Does anyone know if i can flash an image on the xoom that will atleast fix the problem of not rebooting so i can try another tutorial.
I have searched the internet for solutions, many of them linked to threads on this forum. but almost all download links in these tutorials are old and broken.
Can someone please help me unbrick my device? And maybe a link to a good working unroot tutorial for my xoom wifi with android 4.0.4.

Try get back to Stock.
Download from HERE
and do some OTA updates afterwards so everything will be up to date.
Then wipe and try again from scratch..
Worked for me perfectly just a few days ago.

If you can still get into fastboot, then its not bricked.
Get some stock images and flash them via fastboot and you'll be fine.

Indeed it worked. i downloaded the official images and flashed them im on android 3.0.1 again and all seems to work just fine now.
Next problem is i cant find a descent tutorial on this forum how to root the xoom. all download links are either removed due to copyright issues or the links are just broken.
How does it work actually?
1. I unlocked the boot loader wich is very easy.
but then? Do i need to flash a rooted image over the existing? i dont really understand how this works. I rooted my Desire HD with a good tutorial in minutes. Not many people seems to really know how to root the Xoom.
Also i would like to know if the different tutorials are for different android versions or can i aply all tutorials of rooting when i stay on android 3.0.1?
I also tried to flash a recovery.img to the recovery partition and press volume down 3 seconds after the moto logo apears but when i do i get an android robot with a big " ! " on his belly and it takes 5 minutes to load the menu. when im in it tells me there is no sdcard present when i try to flash a rooted rom (zip file).
Is there someone reading this thats willin to explain to me how to do a root the easiest way? Please if links are posted be sure everything on that thread is working. Im pretty sure i will pull it off with some push in the right direction.
Thank you!
(edit) omg im stupid, offcourse the sdcard wont work... it never worked at 3.0.1. on the xoom. can i follow this tutorial:
http://rootzwiki.com/topic/451-how-to-root-the-wifi-only-xoom-301/
Could someone read over it and see if this is a good tutorial? last time i flashed a boot.img the whole xoom got stuck... is that because i had the wrong boot.img on the wrong android version? or should boot.img always work?

Do you plan on flashing to a custom rom after rooting? If so, you can just skip rooting altogether.
I say this because I'm not particularly familiar with that rooting method you linked (though reading through it, it makes sense, all its doing is pushing the necessary files for root access to the xoom via adb). I used a rooting script flashed through a custom recovery over a year ago - unfortunately the download link seems to be broken (I might have a copy at home).
So there's a few things you can do:
1. If you just want a custom rom - download the rom zip file and store on your device. Flash TWRP (my preferred recovery) in fastboot. Boot into TWRP and flash the rom zip file.
2. If you want stock OS root access -
a) Follow those steps you linked and see what happens. If things go wrong, you should be able to just flash those stock images again.
b) Wait for me to get home and see if I have the root script. You'll need to flash a custom recovery though in order to use it.

Ok thanks for your answer. Ill try to unroot with that method flashing directly to the recovery.img i also know now what i did wrong. i flashed the recovery.img not to the recovery partition but to the boot partition LOL. thats why the xoom didnt boot anymore
I see allot about Nightlies Eos, 4.1.1. is that a good rom? Does it look like the stock version?

eos 4.1.1 is simply awesome and its also pre rooted' so your bootloader is unlocked, all you gotta do now is install twrp recovery via fastboot ( my preffered recovery) then flash eos via recovery

EOS is a pretty AOSP rom. No theme, though you can apply one if you like and change a few colors. There are various toggle additions you can add that make the user experience much better. It also comes with an overclockable kernel and is very very stable (despite being a nightly) The team has been supporting the Xoom for over a year and is very committed to the Xoom.

As for flashing, just gotta make sure your text is good before hitting the enter key. Recovery flash should look something like this:
fastboot flash recovery recovery.img

Some instructions for flashing can be found here
While that page is specifically for locking and flashing to return to stock, the commands are universal for fastboot. Hell, if you wanted to, you could manually restore a nandroid backup via fastboot and flashing images.
