As some servers for legacy Sony Ericsson feature phones are offline, I have archived some useful info, links and files which I have collected over time.
I am not aware of breaking any copyright, credits are given where still possible. If you feel that I have violated your rights, please contact me.

Also check out PostmarketOS. If your device is well supported upstream, chances are good that (official) LineageOS, microG derivate or /e/OS works well too. Check out software recommendations

If you want links or files added, email me. You can also request an account for this DokuWiki with me.
Help in the hunt. File in links,packages and ☐ info who have been owners of Omnius to retrieve source code. Do you have any contacts? See the history of owners (top of page)
Do you know the people who made SEFP2? Can you get The_Laser to share sources of setool2?
