problem with unlocking k800i

[Oilers]

hey,
i have a k800i, originally with CID 49, but when i connected with
XS++2.2. it asked me to update to CID 52, so i did a update to CID 52,
then i used the apac firmware to debrand the phone, after that i did a
unlock, but when i turn it on, it still asks for unlock code, what is wrong?
am i missing something? did the update cause the problem since
OTP LOCKED:1 CID :49?

sorry guys,
just found this was not a sim lock,
it was a phone lock, so did a search
