    Sony Ericsson K550i

    Hi, everybody, this is my first post at topsony.com

    Recently I flashed this firmware on my k550i:

    Speed:921600
    Flash ID check:897E
    Flash props sent ok
    OTP LOCKED:1 CID:51 PAF:1 IMEI:356657#19613#1 CERT:N/A
    FLASH CID:52 COLOR:RED

    Model:K550i
    Brand:T-Mobile DE
    MAPP CXC article: R6BC002 prgCXC1250669_GENERIC_LI
    MAPP CXC version: R6BC002
    Language Package:EUROPE_2
    CDA article: CDA102743/156
    CDA version: R3A
    Default article: cxc1250671
    Default version: R6BC002

    Network LOCKED
    Operator: 232-03

    However, the patch did not unlock it. Is there a ready patch for this firmware? Thanks for any help!

    Thanks for making this well done website!

    Might be best to make a fullflash with the right custompack (Main+FS+custpack) and unlock patch....?

    So it worked! At first I couldn't understand this:

    "In Windows Explorer drag the MAIN file (.mbn) onto SETool2 Lite v1.11 folder\qamaker\qamaker.exe. In the qamaker's folder you will get a quick_access_***X_******X.vkp file."

    But then vkp file was generated by qamaker and after 15 min phone unlocked.

    Congratulation on your newly unlocked phone. Hope to hear from you again.
