Unlocking a Nokia 5230 (Hardlocked)

Hey guys, I need a bit of help here.
So I have a Nokia 5230, locked to T-Mobile.
I tried unlocking it using one of those online calculators.
The calculator gave me like 5 codes to try, so I tried the first three to no avail.
Then I found out that 3 errors causes the phone to ‘hardlock.’
I tried googling around, but their are different answers to my problem.
So I’m wondering if anyone on here has any knowledge or experience on this matter.
Thanks in advance.
