So, I rooted my phone, went to ROM Manager and pressed...something (not sure what). My phone then rebooted automatically and said "Custom binary blocked by Reactivation Lock". I gather this is because I didn't click some option on my phone before it restarted.

So then I started looking for ROM's or anything to bring the phone back online. I downloaded Odin and tried installing a ROM and I get "Custom Binary(RECOVERY) Blocked By R/L"

So now, I'm trying to download the stock firmware but, the problem is...I have no clue which firmware to use. I don't have access to much on my phone other then what I can see on the back of the phone.

SM-G925I UD

My provider is GCI out of Alaska and my phone is unlocked from the store. Which firmware do I use because from what I've read, SM-G925I is an international version and I'm not sure which I should use.

One thing to note...I'm the worst nerd ever when it comes to this. Thank you so much for any help you guys can give.
