Need Help on my S7 Edge Duos

I got my S7 EDGE Duos from Smart Philippines. It is of course locked only to Smart Network but I can use Globe Network on the other sim slot. Now I had to flash my phone using ODIN because it was boot looping. I couldn't find SM-G935FD Smart firmware in Sammobile and I have read here in forums that I can Flash any SM-G935F firmware safely because they are just the same. So I flashed an ASIAN SM-G935F firmware it and it worked. Now my problem is, both sim slot are now locked to Smart Network. If I insert the Globe Network sim card, it will ask for a network unlock code.

Kindly help me or enlighten me please..

Thanks
