Hello.
There is damaged security zone in your phone. You can try to make repair security and then make unlocking again, but in this case there is a risk to damage phone's boot.

bluetut · 07-22-2011, 01:28

hello sir,,the phone works fine in UK and lock in O2,why the security zone is damaged?

Octopus box · 07-22-2011, 06:52

Hard to say exactly, maybe the security zone of your phone has some differences from the security zone of another GT540 that we have before.

Octopus box · 07-22-2011, 08:02

Your phone has bad blocks in the security zone. The phone works correctly with such zone (it can pass bad block). But for unlocking of this phone this is the problem. Such phones meet very rarely and hard to add support for such phone without phone in our hands. Please contact us in 1 week, we will try to prepare test version for You.
