There is not a Malaysian firmware for the S7 Edge,
G935F, specifically. So I cannot say which firmware you were running before. You can download the stock Samsung firmwares for the Galaxy S7 Edge, here...
Firmware for Samsung SM-G935F - SamMobile
You can then flash it to your phone using
Odin v3.11.1 by following this video...
Be advised that flashing a firmware other than that that came with the phone, can void the warranty and you will no longer receive OTA updates.
