Hey I was able to unlock as posted in this thread...
Following the method in the first post. Not the app route....(corrupting IMEI) but the manual one ,then reversed it, and did the code one.
So with the new root access one can unlock going straight to the bin file opening it in Hex and location the code. without modifying the bin file itself. The code is there in the file but root is needed to get to the file.
The OP ...comments..: pay attention to the update...thanks to one user discovery
Since this root method is working on Exhibit II...and the two has the 3G band this is a very good thing.
