[HELP] Not registered on network-Selected network unavailable

So, i got this problem on my Galaxy S3 Neo(GT-I9301I) after installing a stock rom with Odin.However, it did't happen right away it happened two days later. I tried every guide and method i could find to fix this issue but it just wouldn't work. After all that i believe that my efs folder got messed up and the worse is that i didn't create a backup, but the good thing is that my S3 still has it's IMEI. Is there anything i can do?

Help me :( Where can I buy Nexus 6P in unavailable countries?!

I have no idea what to do.
I want nexus 6P but I cant buy it, atleast not for European market.

There are offers on ebay but they all come with USA flat pin chargers which is not compatible with electricity we use in Europe

Google doesnt ship to my country (croatia)

Amazon.de, co.uk., .it, etc still dont sell it

Any idea guys?
