International Unlocked Software

[sankyx]

Hello,

I bought a amazon international unlockedgeree galaxy s7. Unfortunately it came with some software issues I took the phone to a shop for they to try to fix the software, then they flashed the phone and changed the international software for a German one!! I've trying to find a way to get the software back but I haven't been able to. Can you guys help me telling me where to download the software so I can install it back

Can't you just take it back to the repair shop and have them flash the correct firmware? Looks to me they messed up by flashing the wrong one.
