Either the board is faulty or the built-in software is corrupt. It may help to re-flash the phone with the latest software. http://www.sonyericsson.com/cws/support/updateservice?cc=gb&lc=en
Back-up all your contacts and texts, and anything stored in the phone memory to a computer with PC suite first, as these will be wiped during the update. Failing that, take the phone back to your supplier and tell them what has happened.

a programme called setool lite could reset the code back to 0000

download setool lite here: http://www.4shared.com/file/VSqGxHQu/SE_Tool_2_Lite_111.html?s=1

turn antivirus resident sheild off (it will report this programme as a false positive)
when downloaded extract file with winrar

turn phone off and remove sim and memory card
do not turn phone back on!
select k550 in the list
press 'identify' on setool lite
press and hold 'c' on the phone and plug usb cable in

it will ask for driver which is in the setool lite folder so direct it to there

after driver installed setool will then read your phone and displa info on the screen

as soon as that has finished unplug your phone, put sim and memory card back on and the security code should be reset to 0000
