That's the spirit!
Here are the steps:
- Be prepared that your S7 will NOT be ready for normal operation for a longer-term. So a backup phone for daily use is highly recommended.
- The porting steps are documented in the latest hadk. Please read it before you start.
- You need to choose an Android base (I recommend Los 14.1, the one I used is available here lineage-14.1-20190224-nightly-herolte-signed.zip)
- At some point you'll face some issues that are not documented in the hadk. You can find solutions in the hadk-faq created by the porters.
- And the last is my detailed, step by step instruction. I have put this together during my work and it is available from here: S7_Porting-guide-by-edp17.txt
Good luck and keep me posted! Just for the record, I am very envy, because I wanted to do this. However as I do not have got the device anymore, I think better to give my knowledge to someone else and let him make it a success for all the other S7 users who would like to use Sailfish OS on their device.
