Using firmware from other countries

Hi, apologies this early on for having a thread this long. I am really needing help on these as other websites weren't as helpful or as detailed on this fact.

As the title suggests, I'm wondering if you can flash firmware from other countries.

I know this has been discussed for so many times. But reading and researching, I always see contradicting answers. Some say yes. Some say it's not safe. Some are unsure. So I would hopefully like someone who can enlighten me and others who may find...
