    You don't need an account and you don't need to buy credits for repairing the EROM; it's free.
    Use the Wotan client. Leave login and password blank.
    WOTANSERVER, erom repair guide, dcu-60 db2020 phones only
    a.Turn off the phone, remove the battery, sim and memory card,
    1.download wotan
    2.run wotan.exe
    3.erase all log-in information
    4.Press start button
    5.Insert the battery then connect the phone while holding down 2+5
    6.Release the buttons then wotan should update your erom.

    I also tried XS++ but as soon as the system detects the mobile, i soon hear a standard hardware detaching sound which leaves the process incomplete.

    here is the log...



    17:05:28| XS++ v3.1 (Darwin) Ready !
    17:05:28| Executed on Microsoft Windows Vista
    17:05:35|
    17:05:35| Attempting to open the interface...
    17:05:35|
    17:05:35| TURN OFF PHONE!
    17:05:35| Hold 'C' button on phone and connect phone NOW.
    17:05:35| You have 30 seconds...
    17:05:35|
    17:05:40| Baseband ID: 9900

    Yeah i tried KKclient and it updated EROM successfully in 0 seconds :cool:

    But The Problem Still Persists.
    The Identify command gives " no ack during gdfs_readvar & Can't read SCRC unit" error. here's the log....


    ChipID:9900,EMP protocol:0301
    BOOTROM MODE DETECTED
    Speed:921600
    Flash ID check:897E
    Flash props sent ok
    OTP LOCKED:1 CID:51 PAF:1 IMEI:35683401134414 CERT:N/A
    FLASH CID:52 COLOR:RED
    no ack during gdfs_readvar !
    Can't read SCRC unit

    Elapsed:84 secs.

    and Read GDFS command gives "CSloader refused to start GDFS services error 29" error.

    Log....

    Will backup GDFS now.
