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..

I think that it worth to have a look on the Thread where our Developers are processing on CM10 here http://forum.xda-developers.com/showthread.php?t=2033551
Then you may see some issues from your flashing have already mentioned, and should also be some solutions available.
Please take note that even the Nightly Versions have been updated frequently (daily from 7 to 9 Dec).

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

downgrading
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.

[Q] Ported ICS XBSA V5.2a LG Mobile Support Tool finds an update...

i am using XBSA V5.2a and the base band is XMM6260.on LG P920. According to phone settings my model is SU760.
when i start lg mobile support tool it identifies my phone as P920 and version is V18A then it says that there is an update for my phone...
what do you think if i install this update?
Also LG PC Suite for ICS identifies my phone as SU760 and when i check for updates, it says that a new firmware is available.
should i install this update?

That update will downgrade you to the latest stock firmware in your country/provider.
Probably one of the V21 versions.

then i skip update via LG Mobile support tool.
but what if i install via LG PC Suite? this pc suite for ICS then it may update ported ics files for better performance?

I don't think so, official tools will take you to latest official software.
But you can try, if you want.

that is the point, i tust on this. because there are two pc suite, one is ver 4 for Froyo and GB and the other one is for ICS and JB.
I used ICS/JB version.
Maybe i will take the risk soon...

don't cause if it recognises your phone as su760 it will update you with the latest firmware for su760 and that my friend is another phone... so u end up with a brick.... my opinion at least...

You will brick your phone, ported ICS have different partition.

I had the same, and posted too. xbsall had replied that even if it is bricked, it can be resurrected using the resurrection guide
so, you can try if you want.

no one said that it cannot be unbricked... we just said that it is 100% sure that it will get bricked. Sure he can unbrick it afterwards but why go in the trouble in the first place?

probability of bricking my phone is very high, but i just want to try to be sure, i only lost a few hours...
i am planning to do it at weekend...

If you mean sim unlock than I don't believe you can, you will need to use Odin/hiemdal to revert to stock ICS and then follow the guide (here in forum)
Once complete you can than flash what you please and will stay unlocked for good
