Hi,

Have you tried 0000 this is the default security.
If it is being changed by the old user then.
you can't to any thing.You have to flash the mobile.
That is you have to install new firmware.So the old
data will be erased and new firmware will be installed.
It will cost around 15$-20$ in service centre.
I don't prefer my customers to at home.Because while
flashing your phone if it stops in between then you
the phone is useless no more.



post a comment for further assistance.
Thank you for using fixya have a nice day:-)

    Only phone memory details will go not Sim memory.Just ask them to take back up of the phone contacts thats enough.If you had saved thecontacts in sim card then no issue.If you have saved in phone memory just ask them to take back up of the data.Take the mobile to the service centre and ask them to flash it.

I bought this phone in Australia on the Virgin network. I live in Canada and have received the code to unlock the phone but I do not have SIM card from a network in Canada, can I still unlock the phone.


You do not need a SIM card from Canada: just use any non-Virgin/non-Optus SIM card (e.g. free pre-paid SIM card from Vodafone could be used) to force the prompt for your Unlock code.

Hope it helps!
