    I am currently on Stock Android 4.0.4
    BUILD – I9300XXBLFB
    BASEBAND – I9300XXLFB
    CSC – I9300OJVBLF3

    as you can see i am on UAE’s CSC but i am in India. My phone was a gift and i don’t know where it was bought from.

    So, My queries are

    1. As XXELLA is having the CSC of UK.. will i face network problems?
    2. Should i wipe my phone to flash? (I dont want root. I just want to upgrade the firmware) !

    Thanks in advance !

    • Vikas says

      1. No there won’t be any problem. You can change your country later on.
      2. Rooting isn’t mandatory. Wiping either.

    Hi,

    I did an OTA 4.1.2 update this morning and now my device shows that Baseband version is : I9300XXELLA

    Does this mean that my phone is now safe from “Sudden Death”?

    Also, will I face any problem when I root my phone?

    Thanks,
    Kunal

    I have S3 which is already “sudden death”. I’ve just open my phone in download mode. I tried other ROM’s, every time I get PIT Partition error. Does this firmware upgrade fix my problem?
    Any idea?

  5. Benny says

    After the update I lost service connection. I can no longer call and receive call. Same for messaging services…
    I noticed that my serial number is now set to zeros… now what? :S
