As I said already, you've no chance of getting the code from O2.
Go to your local market store or independent repair shop. It's your only chance.

Re: sim network pin blocked.Enter sim network PUK

Hi There, 

 

I just wanted to ask if they have found the solution for it? 

 

I have the same error message and receiced the unlatching code but it does not work. 

 

Did they manage something at the end? Or did you get solved differently?

 

Many thanks and kind regards, Sophia

Hi @Sophi91 Have you followed the advice in the thread?

It's nothing to do with O2 if you are being asked for the MCK code. You have to ask the manufacturer first..if that fails  get your phone unblocked by an independent repairer or local market stall..

Re: sim network pin blocked.Enter sim network PUK

The MCK (what you require) is because the phone is hard locked due to too many failed attempts to unlock.
Any network should be able to generate this code from the IMEI number of the phone but we know from previous experience that O2 are either incapable or unwilling to do so.
Your only option is to seek independent help.

Going out on a limb here, but has anyone tried unlatching the phone from O2 first then trying this again? If it’s locked out completely then take it to someone who can fix it with a software change.

It can be fixed with the right software but as it requires writing to a protected part of the partition table it isn’t something that can be done at home by the average person.
