How to install Android Jelly Bean on the Samsung Galaxy S3 right now, without rooting

Samsung has begun deploying the Android 4.1 Jelly Bean update to the Galaxy S3 but it’s a slow process that’s further hindered by networks testing the new firmware before sending it out.

Jelly Bean brings a number of improvements to Google's mobile OS, including better performance and the useful Google Now tool.

Users in Poland have already got JB and other countries in Europe along with the rest of the world will be joining in shortly, but if you don’t want to wait it is possible to install the new OS right now.

You don’t even need a rooted handset.

This is a relatively quick and simple procedure but the usual warnings apply: mucking about with your phone’s software runs the risk of bricking and warranty invalidation. If you get stuck or are unsure leave a comment below and we’ll do our best to help, but we can’t replace your phone if it melts into a puddle of goo.

Please also note that this was done on a European S3 with an Exynos chipset. It may well work on the Exynos version from other parts of the world, but should not be applied to variants using a Snapdragon CPU.

[UPDATE: the official Jelly Bean software is now showing up on UK handsets. Go to Settings > About to check if it's available for you]

What you’ll need:

- A fully-charged Galaxy S3 with USB cable
- Odin
- Samsung Kies, or just the S3 USB drivers
- Jelly Bean firmware. You'll find a regularly updated list of official firmware at XDA Developers. Note that the current JB software is the Polish release. It's in English but if you wait the UK edition should become available shortly.

Backup important stuff before you start! This upgrade should not wipe the handset, but you could lose data if anything goes wrong.

How to install Android 4.1 Jelly Bean on the Galaxy S3:

  • Switch off the S3. Once it’s fully powered down hold Home + Volume Down + Power. The handset should start up with a warning screen, press volume up to continue. This is the S3’s download mode.

 

 

 

 

 

 

 

 

 

  • Connect the S3 to your PC.
  • Run Odin, but make sure that Kies isn’t running in the background (hit Ctrl+Shift+Esc and confirm via Task Manager). You can have it installed but they don’t play nicely when running at the same time.
  • Ensure the handset is detected in Odin; the ID:COM box will confirm this, it’ll turn blue and say something like 0:[COM16]. 
  • Extract the firmware file from the .zip archive to your computer.
  • Click the PDA button on Odin and select the firmware .tar file. 

 

 

 

 

 

 

 

 

  • The only thing that should be selected in Odin is the PDA option, auto reboot and F. Reset Time. Do not tick anything else. (The exception is if there are multiple archives within the firmware .tar file, in which case the ‘Phone’ and ‘CSC’ files will also be included, but this is not the case with this particular JB release.)
  • Click Start.

 

 

 

 

 

 

 

 

  • Progress bars will appear on both the S3 and Odin. The firmware file is big so this can take a few minutes. Odin will say ‘Pass!’ once it’s completed.

 

 

 

 

 

 

 

 

 

 

Your handset will then reset and complete the upgrade. You now have Jelly Bean on your S3, complete with Google Now and Project Butter.

    That'll be because Jelly Bean does not support Flash. You can sideload it though, see our Nexus 7 tips article for how to do that.

    Hi. Will this work on a handset locked to o2? Also can u get updates as they are released i.e 4.1.2 and so on? and can u reverse back and get the official update once released. also if you cant use kies to restore phone from back up once you have changed the csc how do u get everything back to your phone?? really want to do this just a little worried.

    @Chris
    It should work just fine on a network locked handset (comments above you from Orange and T-Mo users) but I did this on an unlocked phone. If anyone else has done this to a locked phone can you let us know?

    You can downgrade back to 4.0.4 ICS, simply do the same procedure using the older firmware and make sure you do a full wipe via recovery after installation. SamMobile.com has downloads for all regions.

    Getting later updates will depend on having a matched firmware region and CSC (though you could just use Odin again). You can change the CSC on the S3 very easily, see this guide for details.

    For backing up use third party tools like Titanium Backup.

    @vince
    Sorry, I should have mentioned this. If your model is one with a Qualcomm chipset then it definitely should not be applied. If the handset is an Exynos chipset it may be okay, but this was European firmware applied to a European model so I cannot say for sure how it will behave.

    That was a mistake in the screenshot, I've fixed it now. Should be the PDA option.

    Not sure why your Odin is freezing when the file is selected. Did you extract the .tar file from the firmware download, you're not selecting the zip file it came in?

    I’ve just done the update, thanks for the instruction. Everything seems to be working ok and the Samsung exchange email app finally works which was the main thing for me. There are however a couple of glitches, for the first 10 min or so the phone was extremely slow, a couple of reboots helped but still appears to be a little slow at times. I can’t connect to Kies and I’ve lots predictive text, I’ve checked the options and everything is set as it should be. Other than that everything looks good.

    Also, I've read with Jelly Bean you're supposed to be able to swipe up to delete photos from the photo browser. Mine doesn't do this, it's exactly the same as it was.

    @roger jeynes
    Unless your phone is a US model it should not have a Qualcomm chipset.

    @jalil
    Bricking risk is low, this is official software.

    @Adrian
    Yeah, Odin is inside the firmware package but it's a slightly older version. Not sure if that makes a huge difference though, it's probably fine.

    Lee H and anyone else with software quirks - you might want to try a factory reset or complete wipe via recovery. Backup first.

    How long will the whole process take? Coz I have a problem with my usb connection. The connection's usually fine at first but after a while the computer and my SG S3 lose connection with each other and the computer can no longer see it in my drives. I'm hoping the whole process wouldn't take long so as to finish the upgrade before they loseconnection.

    That's a strange one. It takes just a few minutes for Odin to copy over the new firmware, but honestly I wouldn't risk it if you're having those kind of problems. If the connection drops halfway through you could brick your S3.

    Just installed with no problems on my S3 O2 uk network. Didnt lose any data from previous ICS and even kept the flash player which still works perfect on Jellybean. The update does seem a bit faster & zips around webpages & screens without any lag, unlike ICS 'sometimes' could. Smoother overall & definately worth the update (if you can't wait any longer). I was a bit unsure about trying this,or whether just to wait for the OTA, but just go for it,its all good :-)

    Sorry, probably a bit late by now, but it can take a while for the phone to start up again. If it's been sat there for a really long time though (like an hour or more) just pull out the battery to force a reset and it should boot normally (though again this may still take some time).

    Hey, wondering if you could help me with something. My phone is unlocked and I'm not using the original operator. I updated Android to Jelly Bean when prompted to (no rooting) and it locked my phone (to original operator, I guess). Now a friend of mine was able to downgraded it back to 4.0.4 so I can use it on my operator but I really wanted to update Android. Is there a chance I'm able to do so with rooting, without it getting locked? I'd really appreciate your help since I've not found this issue around a lot, and noone seems to have a clear answer for this.

    @Joao

    That's weird. Updating to JB should have no impact at all on your phone's network lock.

    Rooting may be the way to go for you, that way you can easily swap out different ROMs and recover from backups if it all goes wrong. We have a guide to that as well: http://www.broadbandgenie.co.uk/blog/20120829-how-root-samsung-galaxy-s3

    Cheers dude :-)

    Got tired of waiting for T-mobile UK to pull their digits out of the respective bumholes and flashed a rom as per your directions - aaaaahhhhhhh!!!! JB goodness.

    So much quicker :-)

    However,

    I had no data connection. Had to manually enter T-mobile APN settings and then all worked fine again :-))

    THANK YOU!!! you have saved my phone. BEFORE it was having big problems as i had rooted it then downgraded it to 4.04 official firmware, but it had serious issues such as messaging app wouldnt open and it wouldnt connect to KIES. Now, having used the UK firmware update available on the site, my phone is working perfectly every way. The messaging app is working again as is KIES (after using troubleshooting process though)!

    :D :D :D :D

    Rooney, if it's failing at the MD5 check it means the firmware file you've downloaded is corrupted. Delete it and download again.

    Hi matt. Thanks for the reply. Really appreciated. I have downloaded it twice, again and it says the same thing. Could it be another reason like my Operating system in the computer?

    I updated my Samsung Galaxy S3 locked to Orange using the method stated above this evening. No issues whatsoever and i'm really glad it worked out ok!
    My partner got the same phone on Friday with Vodafone and i was jealous that his phone was already on Jelly Bean. If anyone is hesitant to do it then don't be. So long as you follow the instructions then everything will be fine.

    Updated my T-mobile UK S3 to Jelly bean using the steps in this article. No problems at all. Took about 10 mins tops. Easy and trouble free.
    Thank you
