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.
