I've just tried to install Sf on cm12.1, obviously with latest TWRP recovery of multirom, seems it's flashed but now it's stuck on "extracting boot image" of Sailfish, is it a known issue?
I know there is a recommended TWRP version, but I was too curious to try it.

EDIT: my fault, everything was rignt flashed and it's working fine, even with latest Multirom TWRP recovery.

EDIT2: Well, I've understand why the old TWRP version is recommended, if you use the new, you can't flash the sensor fix.
I've found a problem, I haven't any data connection with my sim, the apn is right, but in settings results disabled and in light gray, so I can't switch to enabled.
Wifi works fine.
