With Semctool and T28 serial cable I successfuly unlock T20.
But I cant unlock new SE phones. I try with several models T65, T230.
And program notify this:
Connect to phone (I put battery in phone, and press NO)
Check if RSA is active
Bypass boot authority (I press the power button several times)
Initialize boot
Load data to phone
ERROR: 004007
What is problem?
