Flashing = Unlocking?

Hi I have a W810i locked by O2 Germany. I would like to unlock it and I wonder if the phone will be unlocked after flashing it?

Could someone answer this?

Thanks a lot!

No it won't.
Read simox' thread in the unlocking section.
If your phone is higher than CID49 you have no chance to unlock it for free.

Thanks. justme.
Fortunately the phone is CID49. I will check the recommended thread for more information.

Flashing means debranding. Unlocking is to remove sim lock
