[Q] Gear2 Neo firmware question +root + custom faces questions (none samsung user) topic

Hey guys,
I got the gear 2 neo as a gift yesterday, i have an HTC m8 and an iphone 5, i downloaded an application called samsung gear on the M8 (costs like 2.5$) but found out that there is no Samsung store in it (which should be obvious)

So i guess i must root the gear right?

I read that i must have the NE5 firmware, i can't know if i have this firmware or not.. my software version is R381XXU0ANCD , how can i know if it is the NE5 and how can i download the NE5 firmware if mine isn't it?

The rooting procedure isn't a problem to me.

After rooting, will I be able to install custom faces or load some faces i downloaded from the net easily? and how? since my mobile doesn't have the Samsung store so i can't install that trendie watches app or any other app ..

Any help please?

And can I benefit completely from the gear 2 neo if i pair it with my iphone 5?

Many thanks guys
