How I upgraded my AT&T Nexus S (I9020A) to Jelly Bean (Android 4.1.1)

<1 min read

I just upgraded my Nexus S to Jelly Bean over-the-air (OTA). It only took about 4 hours to figure it all out.

I had already upgraded to ICS 4.0.4 the manual way (since OTA never came for me), but that simply did not work with Jelly Bean. I found this XDA thread which led me to try to get the update OTA. A few tweaks later I was able to successfully download the package, unfortunately it never let me install it. So close, yet so far…

A few more unsuccessful tweaks, and then it hit me…

Here is how I did, step-by-step.

  1. Power off.
  2. Remove the SIM.
  3. Power on.
  4. Turn on Wi-Fi and connect to your network (if not connected already).
  5. Go to the System settings.
  6. In Language & input change the language to English (United Kingdom).
  7. In Apps select the ALL tab.
  8. Find and open the Google Services Framework.
  9. Tap on the Clear data button and confirm.
  10. Reboot.
  11. Go to the System settings.
  12. Select About phone.
  13. Select Software update.
  14. The package should be downloading, wait…
  15. Once the package is verified, you'll be offered an option to restart and install. Don't!
  16. Turn Airplane mode on by pressing and holding the Power button.
  17. Now, select the Restart & Install button.

That's all folks!

Thanks so much!!! This worked on my I9020A (US AT&T), too!

The first time, it grabbed IMM76M, then repeating steps 7 - 17 got me the JRO03E update!!!

Chris

Jul 21, 2012

Got IMM76M on the first try. Then repeated two more times, but didn't get JRO03E update. Will try again later. Thanks much! (i9020A, US AT&T)

Worked perfect on( AT&T US). No problems on first try. This is the best method without unlocking the boot loader.

Nice works, thanks for the post.

Thanks for this, I tried manually flashing IMM76M all morning and got nowhere, even factory reset didn't help. But this update got that for me. Have tried the manual update to 4.1.1 found on android central and xda but that's still erroring, I am going to repeat these steps a couple more times.

Success!

Worked for US at&t on IMM76D, updated straight to JRO03E.

The Language & Input change wasn't necessary for me to get the update.

Step 14 taking forever, anyone else have similar issue?

bklyn

WORKED LIKE A CHARM!!!! Thanx A Lot!!!!

Would this also work for a IMM76M ????

Jul 21, 2012

Worked perfectly for me (U.S. at&t). Did not touch language settings. Took less than an hour to go from 2.3.4 to 4.0.4 (IMM76M) and then to 4.1.1 (JRO03E)including allowing the Google apps to update from the Play Store while on Ice Cream Sandwich. Thanks a million. Waiting on at&t OTA's is like watching cars rust.

John

Jul 22, 2012

Didn't work all the way for me. On the first try it got me to IMM76M, but I can't seem to get past that. Anyone else know a fix for this. I keep repeating the method above and still no JRO03E. (at&t)

Stuck on ice cream sandwich. Tried again and again to get jelly bean, but no success.

Guess I have to try some more!

Brennan

This worked great on my att i9020a today. USA AT&T. Followed directions exactly including language change.

Bill

Jul 23, 2012

Do you have to be running ICS or can you do this on gingerbread?

Daniel

Jul 23, 2012

I didn't include changing the language, but it's pulling down right now on my AT&T version. Thanks for the help! I've been wearing out the "check now" button all weekend!

Kevin

Jul 23, 2012

This worked great, thanks so much! AT&T never pushed ICS, but this process got both in sequence.

Only wish I knew about this six months ago!

Ramon

Jul 24, 2012

In my case, I had already installed ICS manually. I followed the steps and It downloaded and re installed ICS. Immediately I tried to get JB but it wasn't downloading. I used the phone for a couple of hours and tried again, same steps. It downloaded and install JB. Thanx

Mark

Jul 24, 2012

Works as advertised: i9020a, AT&T.

Krazy nigga

I did all the steps twice and still no results

Manu

Will this update delete my data in the internal memory card?, including photos, videos, music, apps, etc..., can you please help by answering this question?

Jimmy

Jul 28, 2012

After I clear data and confirm and reboot, when i go to system updates it still says system is up to date

Mike

Jul 29, 2012

Stock non-rooted Nexus S 1090T: Okay, I tried the suggested approach to no avail.

Then I re-inserted the SIM card and re-booted.

I noticed that my wireless icon was downloading beau-coup data, so I waited until it stopped, went into Settings > About Phone, and it displayed the message that it was about to install Jelly Bean 4.1.1.

It uncompressed the 114MB file, and then came up with the prompt "Restart and Install".

AT THAT POINT, I TURNED ON "AIRPORT MODE", and rather than simply exiting and doing nothing as it has always done in the past, it actually rebooted and began the Jelly Bean installation!

Once completed, I turned Airport Mode off and switched my language back to English (US).

I am not sure why the presence of (AT&T) cellular activity would make a difference, but removing it sure helped!

I did get the update to download and verify with these instructions, but I got stopped with the yield sign/exclamation mark every time during the install.

As has been mentioned elsewhere, this is most likely due to an unlocked/rooted phone. To get 4.1.1, I flashed it onto my I9020A using the following: a href="http://forum.xda-developers.com/showthread.php?t=1572307" rel="nofollow">xda-developers.com…

Worked like a charm, and no phone trickery involved.

Jul 30, 2012

Same situation as Mike posted on July 29th 2012.

It worked after following the posted steps and then reinserting the sim card and re-checking.

The 114 mb kernel was downloaded OTA and when it was ready for install I switch into aeroplane mode.

After all was installed and rebooted I switched back to English US

I tried all of the steps as well with an AT&T Nexus S, it said software up to date every time.

John

Jul 31, 2012

Try the link I posted yesterday, mstenberg.

I've already done three phones that way and you don't have to fool the phone into starting the download.

Plus, once you set things up via those instructions, you can flash any of the releases...

Joe

Worked for my AT&T Nexus S I9020XXKI1

Just couldn't wait for OTA... Thanks a bunch!

I have tried a few times but still no luck :(

Roger

I also have an unlocked I9020A and it does not work for me. I tried powering down (Power Button -> Power off) and a battery pull immediately after clearing the data in step 9. Any ideas?

Ross

Aug 14, 2012

There must be something missing in all of this.

I have tried these steps over many days, and from different locations, but the update never occurs.

It always says it is up to date.

Could something I have installed on the phone be causing it to hold onto data that won't let it update?

Narayan

Aug 15, 2012

Thanks. Can anyone rate the performance of JB on Nexus S? Battery life, navigation, anything else?

Narayan

Aug 15, 2012

How would it work with AT&T model on GB 2.3.6? There is no way to check for software update in About Phone menu! Should we upgrade to 4.0.4 first?

Ashutosh

Aug 17, 2012

Worked on first try! Thanks!

Stan

My AT&T I9020A does not have a removable SIM card.

The 16GB storage is built-in.

How do I handle instruction #2 "Remove the SIM"?

Rohit

Aug 19, 2012

This worked for me. Thank you so much. :)

Andrew

Aug 21, 2012

@Stan You do have a removable SIM card. What you are thinking isn't the SIM, but a micro sdhc card. Two different things. Pop open the back and you'll see that it's there. If you don't know what a SIM card looks like read the manual that came with the phone or google it.

I have been trying this on my nexus s i9020a with gingerbread 2.3.4 with no luck at all.

Am I missing something or do I need to download something first?? Are my apps/widgets on boot getting in the way?

Id love to have JB so any help would be most appreciated and thanks for the info in the first place.

Nihar

Sep 10, 2012

This method does not work anymore. I keep getting "Your system is currently up to date". I'm running 4.0.4 IMM76D on my AT&t Nexus S, trying to get JB. I followed all the steps exactly as mentioned above. Any help is appreciated ?

Alan

Sep 13, 2012

Does "reboot" in step 10 means powering off and on again?

Rick

Sep 17, 2012

Can not get this to work at all.

Kevin H

Sep 18, 2012

This appears to no longer work. I'm running 4.0.4 IMM76D on AT&T Nexus S (Same as Nihar, above) and have done all the steps as mentioned. This phone has never had an OTA, I started with the original Gingerbread and flashed 2 updates to get it to ICS earlier today, but can't get JB OTA to work (and can't flash the JB zip manually because the ICS recovery is known to be bugged).

Brad H

Sep 21, 2012

No luck on my i9020a running IMM76D either.

Anyone know the best alternative?

Josh

Sep 25, 2012

Having same issues, tried all the steps multiple times and still was unable to get it to update. After i rebooted from clearing data from Google Service Framework and went into about phone / system updates is said up to date ( last check 06/12/1969 ) for a couple seconds than said last check was current time. Am i doing something wrong??

JT

Sep 25, 2012

Tried exactly as stipulated this evening and no dice for me either.

I tried a second time and force-closed Google Framework Services before clearing data (as mentioned in other posts) but still no joy.

Would turning off Location Services make a difference?.... I think if this did work at one time, that window is now closed... Guess I'm rooting this bad-boy...

Aaron

Sep 26, 2012

Same deal as the rest, i9020A AT&T IMM76M (sim in or out, doesn't matter) can clear the Google Services Framework and reboot the phone and whatever else until I die of starvation and nothing changes. Always 'up to date'!

And today's news about the dialer exploit (the Nexus S will auto dial/execute to display the IMEI instead of making you have to push call, so it is hypothetically vulnerable to the wipe issue) that is fixed in Jelly Bean is like a slap in the face.

Felipe Ambrosio

This doesn't seem to work anymore. Looks like Google fixed it.

Mark

Oct 9, 2012

Tried it again and still no success.

I would not be surprised if ATT never intended to offer the OTA upgrade and shut down the access point once discovered.

Someone at ATT wanted to help the customers get updated.

They are probably looking for a new job knowing how ATT operates.

Google definitely needs to step in and own the upgrade process post JB.

Darren

Add me to the list of people with an i9020A phone stuck on ICS.

It's frustrating knowing there's an update out there if someone would just go to the effort of flicking the switch.

I'd prefer not to jailbreak but I don't see much option.

Chris

Oct 19, 2012

PERFECT - the only process that worked - I tried a lot of variations on clearing/stopping Google Services before this one worked - Genius! AT&T Nexus S I9020XXKI1 - now just waiting for 4.2!

After manually flashing (not rooted) 2.3.6 and 4.0.4, things work fine. But when I try flashing P2lZDQWb.zip for 4.1.1 from Fastboot > Recovery, I get an error after verifying package. assert failed apply_patch_space (16570800). Did anyone encounter this and resolve? please assist. Thanks.

AT&T Nexus S - I9020AUCKJ1, Build IMM76D

Narayan

Dec 9, 2012

I was able fix this after numerous reading and tries. Had to > fastboot oem unlock > flash stock 4.0.4 again, then flash 4.1.2. I used the images from developers.google.com/android/nexus/images

Hope this helps for those stuck with the assert failed issue.

AT&T Nexus S now on 4.1.2 (JZO54K)

I've taken this phone home to India after buying it in the US and am using it with an Indian SIM. I cannot seem to get the phone updated any more? Any particular reason why? I tried the above method, wouldn't work. is there a detailed website that shows how to update 2.3.4 to 4.1.2? Do we need to update to all intermediary OS's before getting to the latest version?
