Sony Ericsson Unlocking instructions for devices

DO NOT use all attempts otherwise your phone will be hardlocked (all phones have at least 10 attempts)

The number of tries is displayed before you enter the code

If you less than 5 attempts to enter the code, contact us first before entering the code

Video proof will be required if code does not work, it's a good idea to film it so we can help trouble shoot what the problem is.
