Android - How to restore damaged Internal SD card partition layout? Tried everything

I found it!

The answer was in PIT file, because as it says here:

you will only need to use this if a firmware update needs to change your partition layout (very very unlikely) or if you mess up you partition table (you don’t want to do this)

Which is definitely my case.

So, I tried that GT-I8190N and GT-I8190 should be used with different PIT files (I tried to use for GT-I8190 one). So I found long list of PIT files here.
