Ok, my new re-Edited answer based on changes and further work
My answer is
First I looked at the location of the graphic you show, https://i.stack.imgur.com/M2ctA.jpg. Taking M2ctA, I applied your steps
Add 3 to my first and put it last,
This gave me M2ctP
Add 1 to my new last and keep it second last,
This gives M2cQP
Add 1 to my new second last and put it first,
This gave R2cQP
Add 1 to my old last and put it in the middle,
This gave R2BQP
Minus 1 to my old last, make it small, and put it second.
This gives RzBQP
looked at https://i.stack.imgur.com/RzBQP.jpg and found an image of a bunch of hex numbers. Bit by bit, the first 7 hex numbers were the ascii representation of Rossija, which refers to Russia. Using UTF-8 to decode...
The rest is
Rossija – svjašcenfaja naša deržava,
Rossija – ljubimaja naša strana.
Mogučaja volja, velikaja slava –
Tvojo dostojanje na vse vremena!
google translator translates to
Russia - our country,
Russia - is kissing our side.
Possibly will, great glory -
Your worthiness at all times!
Slovenian. Thus Slovenia
