Hi guys,

First poster here.

I recently sold what I thought was an unlocked Sony Xperia Z, it turns out it wasnt.

I contacted Three, and submitted the IMEI number to get the unlock code for the buyer but by the time I had sent it to him (within 24 hours of him receiving the handset), he had put in the wrong code too many times when trying to get his O2 sim to work with it.

I believe there is an unlock[x] network [0] error, where the 0 I have read represents the number of tries left.

He has tried factory resetting it, and hard resetting it (however I dont know if this is true as I have never met him in person and cant oversee the process) and says the number remains the same.

Is there any way of resetting this number?

Cheers guys!
