Could anyone share the CM12.1 base ROM (cm-12.1-20160704-unofficial-hammerhead.zip) again? Or fix the mediafire share link, which is now showing file missing.

I also want to make sure that the rom above is the only working one, right? Because I tried some available ones (cm-12.1-20150901-SNAPSHOT-YOG4PAO237-hammerhead.zip, and cm-12.1-20151030-UNOFFICIAL-hammerhead.zip), both end up stucking in the google logo at boot. Wonder if it's due to the wrong base ROM.

Here is how I installed them:
Install twrp 2.8.7
Do factory reset in twrp
Flash cm12.1 (either of those two I tried)
Flash sailfish zip (e.g. sailfishos-hammerhead-release-4.4.0.72-CM121-20221207.zip)
reboot
