unlock mobile sony sk17i from too many pattern attemps
You can check whether or not the phone is "hard locked" as a result of incorrectly entering an unlock code.
tap the following in - as if you were dialing a number to make phone a call...
A new "hidden" menu will appear.
Tap on "service info"
Tap on "SIM lock"
Look at the entry for "Network" - there's a number after it. That number is how many unlocking attempts you have left - so if it shows zero - "0" - then you'll know that you've reached the limit for unlock code entries - i.e.
[x] Network 0
If it shows a number higher than zero, the problem lies elsewhere.
Also - when looking at that "Network" entry, there are brackets in front of the name that will look something like this...
[x] Network 5
If there's no x in those brackets, it means that the phone is already unlocked, e.g.
 Network 5 - that's an unlocked phone which may also be why the phone can't be unlocked - it already has been.
