- Insert default warranty void message here. You warranty is now void :P
- I have not tested this on locked bootloaders, but since I needed to modify the kernel, I guess that you need an unlocked bootloader.
- Note this is not an offical SailfishOS build, and the Xperia SP is not the Jolla phone, so please don't report bugs to Jolla.
- The Sailfish image does not provide recovery, and since the Xperia SP does not have a recovery partition, you need a seperate bootimage with only recovery on it to flash cm/stock/sailfish upgrade
- The Sailfish image is based on a specific version of Cyanogenmod 11, which you will need to flash first.
You can find a bootimage with only TWRP recovery in it here: https://maikelwever.nl/sailfish/recoveryboot.img
