I bought a Sony Xperia Z1 from kijiji (like graiglist) and when I came to unlock it, I released I couldn't. After going to the service menu, I realized that there are no attempts left!
I called the carrier Bell and they said they cant unlock it since it has not been 90 days since the day of purchase.
Is there anything I can? If I unlock the bootloader, will it reset the counter?
