If you can use google to search for the required calculators then this should be helpful.
I used it with my Reality and it worked like a charm!
This from another person but here is the meat and bones of what you need to know.
I can`t post the URL link here so for the whole blog post,
NAM2 LOCKOUT MEID HEX # SOLVED.
(Covered with a SAMUNG ROGUE)
THIS IS HOW YOU FIX YOUR PHONE:
Your first step is going to be to find a HASH CALCULATOR such as HashCalc.
Step 2 is simply to ensure that you calculate the SHA-1 for the MEID HEX number located on the back of your phone under the battery.
When doing this ensure that you are inputing the data as HEX data.
Take the last _6_ characters from this calculated sha-1 sum.
You will use this to find your unlock code by adding 80 in front of those to get something that looks like 80XXXXXX.
This number you will enter into the Windows Calculator (OR any scientific calculator that can conver HEX to DEC)
As stated from here you enter this 7 digit hex code into the calculator and select the DEC radio button afterward.
It will convert the number to decimal format.
USE THE LAST 4 OF THIS NUMBER TO UNLOCK YOUR PHONE....
THIS IS YOUR UNLOCK CODE.
