The easiest way is by map. In other words, read log from phone.. calculate it (or post the log in "Log Request" area) then upload map using the logger...
Other way, is by downgrading phone to version 20 and then unlock it with ziemens 1.22...
There is also another way, by parcial... but i never used it... But it works too.
Best regards.
BTW, i found many topics with questions similar to these...
