I have:

• downloaded the latest platform tools
• got the unlock code from Sony
• tapped seven times to enter developer mode and turned on the OEM unlocking and USB debugging
• told my laptop to pretend that it has USB2 ports
• tried inserting a USB2 hub between the laptop and the phone

And yet I still get:

~/platform-tools/platform-tools » sudo ./fastboot oem unlock 0x0081F67(redacted)
                                               FAILED (remote: 'Command did not succeed')
fastboot: error: Command failed

And:

~/platform-tools/platform-tools » sudo ./fastboot getvar all

Am I doing something wrong? This is a BNIB phone, yet it has a "O2" app[1] on it that I did not install. Have I been sold a pup?
