How to install firmware on Samsung Galaxy S3 with Odin? (Video)

How to install firmware on Samsung Galaxy S III? There are several ways to install firmware on Samsung Galaxy S3 no matter official or custom firmware in tar (or .tar.md5) format. Personally, I still prefer to install Samsung Galaxy S3 firmware with Odin. No need to wait for official firmware release through OTA and Samsung Kies. I can install leaked Samsung Galaxy S3 firmware with Odin. Or try out other region firmware.

  5. Hi Jayce,

    Really appreciate you assist how to clear the counter.

  6. Hello Jayce,

    I recently got a 32gb S3 Phone. Upon bootup, before the samsung animation, a “YES” Optus logo appeared. So I got the impression that the phone was under Optus (Australia). It works with my local sim so yes, I guess it’s already factory unlocked. Its also preloaded with OPTUS apps in w/c is useless since I live in the Philippines.

    I Verified it thru kies and it showed:
    PDA: LF2 / PHONE: LF2 / CSC: LF1 (OPS)

    Is it possible to replace (flash) it’s kernel AND/OR firmware into an UNBRANDED version? If it is, what firmware/kernel version do you recommend (unbranded) and what are the possible risks aside from voiding my warranty (which is actually just fine for me).

    Thanks in advance ๐Ÿ˜‰

    • Hi Dom, I have no much info about Optus SGS3. It should be able to install I9300 firmware if Optus SGS3 also I9300 model.

      Try to consult others with Optus SGS3 at XDA website to double confirm.

      • Thanx for the immediate reply Jayce ๐Ÿ˜€ Anyu, yes I’ve verified it that it’s
        an official i9300. It’s baseband, XXALF2 is even at sammobile. So as long
        as I have a backup of my current firmware, is it worth a try to flash an
        unbranded carrier? And by doing this, it’ll remove the carrier’s bootscreen
        logo and it’s pre installed apps right? ๐Ÿ˜€

  7. im quite confuse, is it the official android 4.1 jb is for all sgs3 without care the build number? i just download the firmware from the link…

  8. Hi Jayce,

    Was wondering does the Poland XXDLIB Firmware have the latest USSD issue?

    And thanks a bunch on your tutorial, i updated to JB with no problems at all. Thanks!


  9. Hey Jayce,

    I have purchased my SGS3 from Pakistan, its not rooted nor i have tried it. Can I still upgrade it to JB with the firmware and ODIN as described by you on this page? Details of my device as under

    Model # GT-I9300
    Baseband Version I9300XXLFB
    Build # ——.I930XXBLFB.

    Thanks in advance.

  10. Hey Jaycee,
    I have upgraded the firmware to JB via ODIN process as explained by you, but the Device Status is showing as Normal instead of Modified.
    1: My question is is it normal to have such status after you have modified.
    2: Can i reverse it back to stock firmware if yes how?
    3: Kies does allow now to upgrade it. Is this normal too?

    Would appreciate if detailed answers are provided or if you have already written on this pls. provide the links.

    Thanks and regards,

  11. Dear Jayce,

    After installing firmware through ODIN and rooting via Odin3-v3.04 and CF-Root-SGS3-v6.4, following are the messages i receive while installing apps and opening CWM.

    “App cannot be installed, free up some space and try again”

    “This version of CWM Manager should be used wit CF-CWM v1.1 or newer, it appears you are running different recovery. Various features have been disabled.”

    Pls. tell me what I have done wrong. And a remedy will be highly appreciated.


  12. Hi Jayce,
    I downgraded my phone from Jellybean to ICS. I forgot to do factory reset on my phone prior to downgrading it. My S3 is now stuck in a boot loop. Please help!!

  13. Hello Jayce,

    I have Samsung Galaxy S3 (US) CDMA service.
    I try to unlock, first I try to Root with following website

    and my phone took first .tar file and did not
    reboot. I try with other .tar file to re root but now phone does not start. It just show samsung logo and blank (black) screen.

    Can you help to reset original setting and suggest me to how to unlock.

    Thank you.

  14. Also screen reads


  15. Hi, I’m not getting the official JB update, I think it may be because my CSC code does not match my firmware.

    When I run *#1234#

    it gives

    AP: I9300XXALF2

    but my CSC code shown in KIES says MWD.

    I’ve tried CSC selector but it doesn’t show the BTU CSC code.

    Is it possible to update the CSC codes so I can get official UK JB update?

  24. Hello, Jayce.

    I have a bit of a problem:

    I installed Samsung Kies and followed your instructions in your video on downloading and extracting Odin. However, when I got to actually starting Odin, the little blue bar that appears just before the download starts did not appear. Did I miss a step?


  25. Trying to upgrade gs3 to latest official 4.3 uk version, while my samsung belongs to India. Should I leave out the CP part in the odin, so as to avoid problems with my local wi-fi connection. Please advise.

  26. What is the difference between stock firmware vs. stock rom? I am attempting to unroot my i535 (version 4.1.2, baseband versioni535vrbmf1)
    A link directly to the stock rom would be excellent.

  27.

Hope you have answer in my problem thanks

  29. Hi everyone, I have tried this method, but mine says “failed, there is no PIT partition”, what do I do, what am I doing wrong here?? Any help would be nice.

      • Thanks for the reply. My phone says built in China so I have tried two different China firmwares but both times it said “failed, no PIT partition”, so what firmware do you exactly recommend? Also I just want to say I cant access recovery mood because the phone gets stuck on the samsung logo when you try to turn it on or access recovery mood. Any advise will much appreciated. Thanks

          • Hey. How would you fix this problem on other models…like say any other country model if it wasnt chinese model. What would you do…just try different firmwares?? Can you use firmware from any country to put on your phone…or not.
            Also how do you fix such a problem that when you turn the phone on it is just stuck on the samsung logo. Lets just ignore the fact that it is a chinese model.
            Sorry if iam asking too much its because im not very pro at these things and i dont what xda forum is :/

            • Install another firmware should fix on international model. Yes, you can install any other country firmware as long as the model is the same.
              Normally, I factory reset then install a new firmware if I face this kind of issue.
