      Go back to recovery and perform wipe cache partition as well as wipe data. It will erase your phone’s internal memory data but should fix the issue.

      • Rami Asia

        its ok thanx for your help …… the mobile is pretty with 4.1.2 firmware

  • Norm

    I tried flashing this but this happened:
    __Xmit Write fail
    XmitData Fail..
    Complete(Write) operation failed.
    All threads completed. (succeed 0 / failed 1)

    Now I cant boot my phone it shows some yellow triangle.
    Anyone else with this problem?

  • David Mullineux

    Did this and all worked. Can make calls and APN networksettings were retained from previous version of Gingerbread. However, now phone will not connect to any data network. Not sure if this is bug or by design as the firmware came from a Portuguese carrier ( foreign to my country )

    • arafat21

      This is carrier branded firmware. Wait for a carrier unbranded one.

  • Hoho Ho

    can apply on i8160P ?

    • arafat21

      No, both model have separate firmware.

  • Der

    Upgrade also worked well for me, however; sim card not detected is my only problem, went back to original GB and it all works. Any help with this problem will be cool.

    • arafat21

      Two thing to try. First try re-inserting the SIM, if that not work then reflash the firmware. There is no other solution we know if SIM card isn’t detected by device.

  • arafat21

    This firmware is carrier branded hence only work with TMN subscriber in Portugal. Wait for a non-carrier branded firmware. We will cover it as soon as the firmware available for download.

  • Mark Rafferty

    I just updated to the portuguese TMN jelly bean rom using odin. It was simple enough, but I can’t use my 3G or any mobile data network. When I’m wifi everything works fine although my RAM is now really low – 482MB – is there a way to fix these two problems?

    I’m using a gt-i8160 bought in Vietnam and using it on the Veittel network.

    • arafat21

      Check your APN setting. You may need to manually enter your 3G setting there.

  • arafat21

    China version of firmware shouldn’t work anywhere outside China.
