Download official Samsung Galaxy S3 firmware

Samsung KIES is not the only way to get official Samsung Galaxy S III GT-I9300 firmware. You can use Check Fus Downloader to check for latest official Samsung Galaxy S3 firmware upgrade. And even download it and install with Odin manually later. Or you can find them at XDA Forum and SamMobile website too. With Samsung Galaxy S3 unlocked bootloader, you can try other region firmware too. For example, my Samsung Galaxy S3 is Malaysia unit and loaded with South East Asia firmware. I can install UK I9300 firmware on my Malaysia SGS3 since international SGS3 hardware is the same. So no need to wait on your region firmware for long time and try other region latest firmware first. Europe region always get the latest firmware first. And Malaysia will get it several months later…

UBALE6, XXALE8, XXALE9, XXALEF, ZSALED, BVALE4, XXALF2, XXALF6, XXBLFB, XXBLG6, XXBLG8 and XXBLH1 are the current official Samsung Galaxy S3 stock firmwares available to download at XDA Forum. And there are carrier branded Samsung Galaxy S3 firmware to download too. By the way, be sure to download your current official Samsung Galaxy S3 stock firmware and store locally. You might need it when need to send back for warranty claim. Oh, can’t wait for Android 4.1 / 5.0 Jelly Bean firmware to come…

  1. Hey Jayce
    I just sold off my S2 hoping to top up and buy the S3. Few questions:
    1. What’s the hype about the pink ink spots issues in the S3 screen, does affect all of them?
    2. Is the display inferior to S2 since its not amoled plus? Is the difference noticeably obvious?
    3. Is the battery life noticeably better than S2?
    4. Should I buy it? Or should I simply buy another S2

    5. Any other significant observations u have about S3?

    Thanks. Your response will determine my next decision

    • 1. I believe most of the SGS3 will have pink tint screen. This is design issue.
      2. 720p looks better. But you still can see PenTile effect if you look close enough.
      3. Yes. Or slightly better.
      4. Up to you. πŸ˜‰
      5. SGS3 is the best Android phone out there now. But has it own weaknesses.

  2. Hi Jayce,
    If I wanted put a UK firmware on my phone, how can I tell which one to choose? There seem to be a few.
    United Kingdom (O2) 4.0.4 I9300XXALE8 I9300O2UALE5
    United Kingdom (H3G) 4.0.4 I9300XXALE8 I9300H3GALE4
    United Kingdom 4.0.4 I9300XXALE8 I9300OXAALE8

    The current PDA number on my phone is I9300XXALE8. Also, I don’t want to end up locking the phone to a UK carrier. Thanks

  4. Hi there Jayce,

    My current S3 build number is I9300UBALF3. Based on the number, my firmware region is from Brazil. I would like to wait for my new firmware via OTA, so which software update region should i choose? Country Brazil or Malaysia, FYI i am living in Malaysia or it does matter. Thanks.

Also by flashing another region’s firmware wud be be impossible to use it in australia including 3G internet?
    Thanks in advance

  6. Hi Jayce,
    When trying to look up the latest firmware on sam mobile or xda, how do you find the right one? Does the ‘phone’ have to match the one you’re downloading. For example, do I have to get a firmware that has XXLE8 as the ‘phone’?

  7. Hi Jayce … Need Your Help. Im using xperia neo v . Im interested to use samusung s3 apps in my handset . Im using the latest ICS 4.0.4 in my handset. Can i hv some interesting s3 apps like stock camera, s-voice & etc application plz..

  8. Hi Jayce!

    Fantastic website!

    One question:
    I’ve rooted my SGS3. And I’m worried that I wont get my hands on Jelly Bean at once it releases. Can I update my SGS3 to JB with KIES even though it’s rooted? And will I have to find a custom Jelly Bean ROM, or will KIES download the official one?

    Sorry for the stupid questions. I just converted from iOS, hehe πŸ™‚

      • Thats great news. Im very new to the whole Rooting concept.
        Thanks for your quick and informative reply.

        Keep up the good work. Will keep reading your site!

  10. hey i was just wondering if it takes an unusually long time to update to the latest firmware on the s3 i got it to the screen where it shows a green android then it froze any suggestions to update the firmware successfully

    • Hi Sudharsan, please use Check Fus Downloader to check. The are several firmware for Singapore. I don’t know which one is yours. Kernel is included in firmware.

  11. Hi Jayce
    I amencountering an insufficient disk space problem on my sgs3 when trying to upgrade firmware, I cannot even restart on recovery mode because of the disk issue, this is a new 4ne with standard apps

  12. Hi Jayce,

    I see allot of the download choices for the firmware (4.0.4). My concern is, The choices showing for the UK are showing the carrier as unbranded. My carrier is 3 Mobile. How do I know which one is the right one to chose. Will the phone boot detect the right carrier based on the sim card. Will this infact unlock the phone.


    • Hi Darren, I wish that I can give the confirm answer but I can’t since I don’t have locked SGS3. Try to consult others with locked phone at XDA Forum.

  13. Hi mate. Just installed 4.1.2 jellybean software via root box but its not what I want. How do go back to 4.04 firmware. Pleas if u could help me out it would be very much appreciated. Cheers.

  14. Hi Jayce. I recently rooted my phone but it’s running slow so now i want to restore it back to original firmware. I forgot to write down my old system information so I have no idea what firmware to download. I live in Norway and I have a sgs3 gt i9300. I found a stock firmware for Greece for the sgs3 i9300 model. I want a European firmware because of the quick updates. Can i use this firmware? Can i use all firmwares as long as they belong to the i9300 model or do they have to match my country, baseband, PDA, CSC and all that?

    Sorry for asking so many questions. Just want to make sure i don’t install the wrong firmware πŸ™‚

  15. Hey jayce/anyone.

    I have a GT19300T model of the galaxy s3 I am NOT rooted. However I used Odin and put the new leaked UK jelly bean firmware on my handset for GT19300 not GT19300T.(which has no made my phone think I am a GT19300 model) A lot of websites said there is no difference.wrong. cut to the chase. Do you know where I can get a stock current firmware for GT19300T for a Australian Vodafone handset so I can restore to stock? Sorry if I sound like a noob, I should have just waited for jelly bean to be released in Australia from my carrier.

    Thanks in advance

  19. Hi Jayce, i rooted my Samsung S3 and i want to unroot my device, do you know a site where i can download the stock firmware SGS3 for Philippines, other than sammobile (hotfile).


  20. Hi Jacy!
    I have purchased glaxy s3 couple of months before from Kuwait. I have downloaded kies on my pc (updated version). Now i m a updating firmwre. It stops working at 99%. I have tried many times but still not working. where is the problem. Maybe the problem is regarding region because i have downloaded with UK region. if yes then from where i can download kies for kuwait region. plx help!


  21. hello Jayce.
    I’m a new owner of a Samsung Galaxy S3 and I need your help.
    If I connect my phone to Kies then the folowing text is displayed:
    PDA: LF5 / PHONE: LF5 / MODEM: LF2 (VDH).
    Then if I go to check the last software for the VDH models, on samsung firmware site, a new version (4.1.1) apears.

    My question is why this update does not apear on my phone or on Kies?
    I curently have the 4.0.4 firmware on my phone.
    What I can do to get the JB update? If I must update via Odin, how do I know if I get the right firmware for my phone?

    Thank you.

  22. Hi Jayce

    I am in the process of downloading Android 4.1.2 Jelly Bean XXELK4 Firmware for Samsung Galaxy S3”.

    XDA developers warn of the following:-

    “TheThis firmware doesn’t contain any Modem so the Modem you are using before flashing this firmware will remain” To your knowledge, is this an issue?

  23. Hi Jaycee,
    I have rooted my galaxy s3 but with CF-Root-SGS3-v6.4.tar instead of CF-SGS3-CWM-v5.5-v1.5.tar. My rooted phone have both SU and CWM. But the CWM said that i used a wrong file and some function are disabled. Looks like i need to root again.
    Do i need to unroot the phone and then only root it with the right .tar file?

  24. Hi Jayce. I have already changed my original kernel and rooted my SGS3 with Exynos Abuse. my baseband version is XXDLID and i want to restore the official firmware. I “unroot” my device and i try to update my phone ,but it says that my firmware is modified and does not allow me . Could you give me a hand with that?

  25. Hi Jayce im from south africa and i rooted my galaxy s3 and installed a custom rom 4.2.1 i just wanted to know if i
    can install a samsung official rom from united kingdom bt it says carrier unbranded will it pick up my network

  26. Hi I was just wondering if anyone could help me. I have a samsung galaxy s3 and just randomly the phone has started to do a random boot loop. I was able to get it into the safe boot and redo the factory reset by holding the volume up home and power button but that only stopped the problem for about a day and now the phones starting to boot loop once again every now and then the phone will completely boot up and stay booted for a few mins before it automatically shuts down and starts cycling again. Any idea as to what the problem is and how I can possibly fix it. I have the I747M varient of the s3

      • It’s really weird actually. Yesterday my little brother figured out that by continually pressing the home key the phone stays on. I was able to get it into download mode and then using odin was able to install all the stock software. The phone was working perfectly fine and after 24 hours the phone started to do the exact same thing. The phone is entirely stock and has no apps on it.

          • It’s alright the phone screen is cracked so it’s considered out of warranty I guess its kind of a lost cause now. But thank-you for taking some time out of your schedule to try and help. Really appreciate it.

    • HI Kai, you can install any region I9305 firmware. So Singapore firmware should be yes.

      No idea about death screen issue on Singapore firmware.

      Can install I9305 firmware only. No I9300.

  34. Hey Jayce. There’s a lot of hype going around that downgrading from 4.3 to 4.1.2 etc will brick your phone. If you know anything about this it would help. That, and are there any real legit sites you know of that will unlock your phone for like 20-30 $? Any help would be deeply appreciated. Thanks
