hi all,

I am afraid, you cant..
only you can do is unroot and go back to stock rom HC 3.0 ...

if you are rooted, just install an ICS ROM. (it will also block any JB OTA)
if you are not rooted - get rooted.

The only way I know is to flash ICS ROM if you are rooted

Lol, I just said that.

Well, I know another way... But it can take time...
Get the Stock imgs for Xoom and flash them (beware you'll lost ALL your data, even your precious photos and songs!), then you update until ICS again...
Or get rooted.

It's not possible to root it anymore. xoomroot.zip has been removed from the internet.

Just a question about the 4.0.4 update via Odin. Will this delete your apps and app data? I don't want to lose my place in all of my games. I don't care about email, calendar or contacts since that's all stored in the cloud (Google).
Had this same issue.. trying to update on the device itself resulted in booting into CWM and then giving an error.
You can update using KIES though without losing your data. You will however have to re-root + install CWM again afterwards.

Upgrading AT&T Nexus S i9020A to ICS and then JB?

Hey all,
So I just bought a cheap Nexus S from a dude on Craigslist and want to update it to ICS via OTA, but it doesn't look like there's an update available from Gingerbread (very frustrating). I've heard that in order to upgrade the Nexus S on AT&T to JB, you've gotta have ICS first. How do I go about with this process? Or can I just flash a JB build from XDA here via CWM if I install it? Which is easier? Thanks guys!

If you want to have a clear stock ROM i think better flash stock.img, bootloader and radio via fastboot..
But if you prefere update via cmw also have a look at this.....

I'm also considering upgrading I9020A from ICS to JB.
Currently I have custom AOKP rom.
Is it possible to flash stock JB over what I have now ? if yes, how ?

Yes its possible you must flash a full image..
I´ve posted a link above there you can find the images for your phone. you have to flash it via fastboot.
S.R.
If I flash a full image, do I loose Boot-Loader unlock ? Do I need to ROOT again and install CWM ?

This link explains how to have JB stock rooted. Just get the appropriate files for you phone, the OTA needed and your set. Good luck.

you don´t loose bootloader unlock, but if you flash a plain jelly bean stock you loose cmw and root
because i think JB stock ROM ereases CMW . root you loose on stock ROM´s anyway...
so you can flash this rom as an alternative:
http://forum.xda-developers.com/showthread.php?t=1784666
...it´s a stockROM with a few lttle features like boot in recovery menu or battery in %
all other stuff is stock ...it´s also pre rooted and deodexed......all you need...and it don´t erease cmw while installing..
you can try ...it´s your decision..

root ota jelly bean

how do i root the ota jelly been update?
you can't yet. If you want root you will have to flash back to ICS, Root, Download Voodoo OTA Rootkeeper, backup SU, temp unroot, OTA to JB, restore root.
Thanks, GoCliff. Unfortunately, my XDA/Google-fu has failed me and I'm not finding instructions on how to flash back to ICS.
Any tips?
Get Matt's utility... phone into fast boot mode. And flash back

you can SBF back to ICS using RSD Lite, and its super easy to do. Shouldn't be too hard to find instructions too
Can someone post or link to instructions how to flash back to ICS.

Seconded. I would very much like an explanation that's Linux-friendly as well if someone knows one.
One other question for those in the know. Will instructions for the Maxx also apply to the Maxx HD? I know there are some physical differences between the phones, in addition to the screen resolution, but are there other significant internal differences that make rooting & ROMs incompatible between them?
EDIT: same question for HD vs Maxx HD. Significant differences, other than the capacity of the battery, that will cause ROM & instruction incompatibility?

Here is the link I used. Once you SBF back to ICS and root your phone make sure you download voodoo and protect root and then temp unroot. Then there will be 2 system updates. The first one is pretty small and doesnt take too long. The second one is Jelly Bean and takes forever to download. After Jelly Bean is done installing you can open up voodoo and restore root.
Works like a charm, did it to my phone and my wife's phone yesterday.

I received the upgrade yesterday, xt925 with ICS retail. I felt the system more agile, some icons has been changed and two new application installed with ROM, Netflix and Saraiva Digital(Bookstore). I don't liked the changes made in 'contacts', they put a white background, the menu block 'group' 'fav' 'contacts' are ligh blue color with white font, looks strange because the another things like app menu, config menu e etc still in black...
has new transition effects, they looks good.. Well this is my first contact with JB...
Have you uninstalled or frozen any system application? I had to restore mine before the update or it wouldn't work

****... I uninstaled some applications... but no one system... some aplications like netflix and saraiva... Rather than restore original rom it would be easyer to install the retail 4.1 from SD... but i can't find it anywhere...
I'll try use OTA root keeper and temporaly unroot... then instal OTA 4.1... if doesn't work I'll restore 4.0.4 original and upgrade...
thks a lot for your answer...

Yep, Netflix and Saraiva are system applications. They come with the ROM. Did you use Titanium Backup to remove them? I did that too, but now I think the best is to just freeze them and unfreeze when needed.

So guys,
I've just bought my HD through Claro. If i'd like to update to jb now and be rooted, is the following process correct?
1: install ics retail version BR.
2: root it somehow.
3: use voodoo or the likes to keep the root.
4: Upgrade to jb. (Could it be done normally through the system, OTA? Or would I have to flash it?)
I'm also wondering about Motorola's unlocked bootloader.
Is it better for me to try another way to root, so that I can keep my warranty, or is it better to just unlock it trough their site?

[Q] 4.1.2 Update ** Lost Root ***

Oh god please help me!
-- Have Droid RAZR Maxx HD on Verizon
-- Was rooted on 4.1.1
-- Followed instructions on here to keep root while upgrading to 4.1.2
-- Mistake I seem to have made ---> took the upgrade from the Motorola Utility when connected to PC instead of OTA
-- Now when I go to Voodoo ... there is no option to restore root!
Please god help me ... I really need root... :crying::crying::crying:
Any kind soul have a step by step instructions for me to get root back??
Need to be a little more specific on your device brand. Like if your on the xt926 consumer edition like me then your stuck on 4.1.2 because u can't downgrade ur firmware to go back to ICS and get root.
However dev editions or other variants may be able to obtain root again.

Frock that's what I thought but was holding out a little hope. Yes XT926. This blows ... so that WAS the mistake? Not doing the OTA update and instead the connecting to PC and doing it from the Moto utility?? I assumed it's the same thing so wasn't careful about that.
Thanks.

BTW .. why is rooting Motorola such a pain ... I love this phone for it's battery life but I may go back to Samsung phones ... at least there it's crazy easy to root, change roms, etc.
Rooting Motorola is such a pain because of the locked boot loader IMO. I have root because instead of flashing the new update I used voodo and took it strictly ota with my 4.1.1 rooted device.

So, please, make me understand...
Ok, so, let me see if i understood:
there is no way to root JB...
BUT... developers r trying to, is it right?
so.... or we try a crazy thing getting back to ICS with a really complicated rule to follow or we wait for a good friend here who can give us a root for JB?
Is it right? Cause if i am wrong, if there is a way to root JB, please, let me know.
My phone uses 700 MB of RAM with softwares i use not, i want to put it all off from my phone, but they r from the ROM VIVO Brazil...
Help, please?
