Nexus S Update

Hot on the heels of the Nexus One getting an update, the Nexus S is now in the throes of a 17.5-megabyte download that brings Android 2.3.6 (build GRK39C) along with "bug fixes and security patches." Should just take a couple minutes to update, and then you'll be able to go back to lording it over your friends that you have the latest update, and they're still twiddling their thumbs.

Looks like this indeed fixes some of the tethering issues we'd been seeing, which is nice. And if you crack open the zip file you'll see patches to just about everything -- with the biggest changes to the NFC function

If you're not in a waiting mood, we've got manual install instructions after the break.

Thanks to everyone who sent this in!

  • Grab the OTA package here
  • Rename it to  This isn't needed for the Nexus S bootloader, but it makes things easy.
  • Copy it over to the internal storage on your Nexus S.
  • Power off, then hold volume up and power to reboot to the bootloader.
  • Using the volume key to navigate, select recovery, then use the power button to confirm
  • When you see the warning triangle and arrow, hold the power button and tap volume up.  You'll see a menu.
  • From the menu, select "apply update from /sdcard", and choose from the list.
  • Let it do its thing and update your system, radio, and other partitions.  When finished, choose "reboot sys

Hackery bonus round -- I had to jump back to stock and apply the OTA manually, here's how I did it quickly at 2:00 AM:

  • Download the stock GRJ22 build direct from Google here.  This file contains the full stock ROM, including recovery and radio.  Copy it to the root of your USB storage.
  • Flash it from Clockwork Recovery or stock recovery
  • Wipe data and reboot system
  • Grab the GRK39F file from the steps above, and flash it with stock recovery. This should have installed when you flashed GRJ22 above.  If it didn't, reboot again.

You're now back to stock and current.

Maybe you've been blacklisted...

Do you have space on your SD card? I had that problem before, but no specific notice.

The Nexus S 4G has a update to 2.3.7. I posted this on my twitter with a picture as proof days ago

ghost010 says:

this sint about the 4g you moron...

takkun1946 says:

There's absolutely no need to call someone a moron. Informing and insulting are 2 different things. Lets try and tone it back just a hair and be a bit more helpful

Rofl, but it wont let me download the ota of 2.3.6 OR 2.3.7

I have 13g internal storage and 700mb internal.

pearljam5000 says:

I got it,but i don't notice any difference at all from 2.3.4

epyon says:

Where is the GRK39C to GRK39F update for those of us who got the original broken 2.3.6??


SuperIVIan11 says:

Does it break wifi and tethering on the T-mobile version? Right now I have the Nexus One with 2.3.6 and it didn't; but I was reading how it wrecks tethering on the Nexus S.

BartmanJax says:

Nope. 2.3.6 has no effect on tethering on the T-Mo Nexus S. Just updated mine this morning and I'm still good. No improvement in the wifi signal reception either. I was hoping for that improvement.

I manually installed the update but I am still at the GRK39F instead of GRK39C. It says I have the 2.36 update also. Did anyone else experience this ?

SuperIVIan11 says:

I just checked mine, I'm running a T-mobile Nexus One, but I received the 2.3.6 update Sunday and my build is GRK39F.

MrszBerry says:

What about Att nexus s?

toonhead85 says:

I second this question, though I am rooted w/ CM7 (7.1.0-RC1) and am quite happy.

ottawaxblade says:

Any word when 2.3.6 will be available for Canadian Nexus S owners?

gandarez says:

Hi Guys... I have a big doubt..
Can I update my Samsung Galaxy S II to this version of android or I need to wait to get a update from Samsung?

Donmeister85 says:

This update is for the Nexus S. Not the Galaxy S2.

takkun1946 says:

To further answer your question. You will need to wait on Samsung. Each device has their own update, since each one has different hardware (even if it's just a slight change). This means the drivers (underlying software that lets the hardware communicate) are most-likely different.

If you have a Nexus S, specifically a T-Mobile one, you should be fine. If you have a Galaxy S II, just be patient. :D

Deacon#AC says:

Um, I think I'm confused.
I just got the 2.3.7.
Am I supposed to update again to 2.3.6?

Gone24 says:

You probably have a Nexus S 4G, this update is for the T-Mobile Nexus S....

Deacon#AC says:

Oops, My bad. Completely missed the "T Mobile" in the headline.

flair up of dyslexia.........

Thanks for the clarification.

its_lucky says:

what confused me is that the article reads;
"brings Android 2.3.6 (build GRK39C)"

but the the zip file is named;

is the zip file the right build for the Nexus S?

BartmanJax says:

I believe the GRK39C referenced is a typo. I got the OTA this morning and the build is GRK39F. I also downloaded the zip and did a manual update just for SnG's and it's still GRK39F. The .zip file is the correct one.

its_lucky says:

cool! thanks for the info!

Hope Google fixed that annoying Market update glitch where if you update more than one app at a time it always fails some of the updates due to "insufficient storage"...even though the phone has plenty of space left...

takkun1946 says:

I don't believe this would be a OS version update, but a Market App update. The Market app is a separate app and will most-likely be updated separate from the OS updates (which is what this is).

Have a look at the link above and see if it's a known issue or not. Depending on that, you should submit a bug report to Google in order for them to take a look.

its_lucky says:

after i did the update, SU doesn't work anymore and neither do the apps that require SU Permissions.
anyone else have this issue?
bootloader still says "unlocked"

update: I'm a noob. this is normal. just need to reflash CWM and reroot

/wasting your time.

johnpenny says:

Hey its_lucky I am in the same boat as you, Could you please help me? I hope you see this soon. I bought a Nexus S i9020T from someone recently from local classified, it was rooted, unlocked and had superuser working on Android 2.3.5. I did the OTA to 2.3.6 and I'm pretty sure superuser was still working until i updated it via market and now i get the permission denied issue as you had. I went into recovery and its just the stock android recovery I don't see CWM which I'm sure was on there before i updated to 2.3.6. Please help me asap. e-mail me if you can to I would appreciate instructions along with files and also will I loose everything on my Nexus S? I have TONS of apps downloaded that I used regularly. Thanks again hope to hear from you soon.

Just updated my Nexus S (Baseband I9020XXKF1) to 2.3.6 with the OTA update, everything worked fine.

Most importantly, tethering (Wifi) is working just as before, although I had to set the password again.
