A new update was released by Samsung for the Galaxy S3 I9300. Apparently the update fixes two of the most controversial issues found in models all around the world of the Galaxy S3: the sudden death issue and the security issues with the Exynos 4.

Update I9300XXELLA fixes the security issues that allowed access to full Physical Memory without rooting the device, so any app had root access without anything to do about it. The new released update fixes this Exynos security flaw. Also you surely have heard about the sudden deaths among Galaxy S3 units all over the world that had no fix but to exchange the phone. After a little research, we found out that this update also fixes the Sudden Death issue.

    That’s a pretty bold assertion about SDS being fixed – what did your research entail?

  • Erik

    Is it possible to fix an already “dead” device?
    my galaxy died yesterday so I guess it is impossible to update it now and they will probably replace my phone :(

    • Monika

      No, without ability to boot, you can’t do anything to the phone without special hardware.
      Take it to service, even if the device is rooted, the SDS will be fixed without questions.

    Would have been good to know about the update before my S3 died.

    Hate having to go back to my slow old phone with a tiny screen.

    Basically, my Samsung Galaxy S3 was PERFECTLY working (PERFECTLY!!!)
    Until when I read a post on the XDA site about an app that tests whether you have the brick bug ( from

    Anyways, running CrDroid v8 custom rom and paranoid, I took and passed the test even though my chip was one of the bad (“insane chipped” as the app says) brick-bugged batch, however to be completely safe I decided to upgrade to the XXELLA version and that’s when EVERYTHING goes completely wrong.

    Basically two days later I leave my phone charged in overnight and around 6am, I decide to take out and put it next to me while I slept (Had an alarm set for 7:30)

    However, by 8:30, woke up to see my dead phone beside me, meaning the phone must have died between 6:00 and 7:30 as I did not hear an alarm. (A common trait with a previous poster in this pre-updated article who woke up around that time to find the dead phone) –

    Anyways, my advice to you is if you do pass the test, DON’T upgrade whatsoever. Mind you, my only mistake is that i didn’t run the eMMC app on the XXELLA ROM to check that it fixed the bug.

    So **SSED OFF!!!

    *calms down*
    Now my question is this, I bought this phone on Contract with T-mobile however, I want to know if:
    1) It’s better to send it to one of those companies for a “JTAG”
    2) Should go over to a Samsung Store for a warranty? (Still under 2 years since the S3 came out last year)
    3) Go to T-mobile for a replacement.

    And that does the JTAG process lose all my internal storage data and contacts e.t.c
