  22. Hi,

    I’ve been trying the above workaround:


    1. First of all, the Firmware updater is not asking for the PASSWORD but just continues to download and completes the updation successfully. (Initial Version : TCPU_HWEC152DT01, Updated version :

    2. Dashboard updater fails with error 2 – the datacard can’t be found

    3. The data card is in the COM5 Port. The CDMA Workshop connects to this card on COM5 though could not return anything on READ – it said, “Failed…..Phone doe s not answer.”

    Any workaround possible…??

  23. Dear Sir I need to know , after unlocking it wheather it will support BSNL EVDO or not?
