Add a new ROM

• Before you do any of this you should download a ROM .zip file (for example FP Open 16.09) and put it on your SD card (/storage/sdcard1/ and !!NOT!! /sdcard!).

=> FP Open 16.09

• To add a ROM click the FAB (Floating Action Button)

• Choose in the screen /data/media/0/multiboot as location.

• Enter a name for the ROM

Add a system to the new ROM

Once you are in the UEFI, you can navigate around with volume down to go down, volume up to go up and the power button to confirm your selection.

• To flash a ROM the empty slot, select TWRP (Internal) and press power.

=> Image

• Next select your newly created ROM

=> Image

• You will land in TWRP and be greeted with a warning about keeping the system partition readonly. Swipe the slider at the bottom to acknowledge it.
• Click Install, select the Micro SDcard at the top.

=> Image

• Select for example the file fp2-sibon-16.09.0-ota-userdebug.zip.

• Disable the Zip file signature verification and slide the confirmation bar.

=> Image

• Everything should be good and you can reboot!

Booting into your new ROM

• Select your new ROM and press the power button. Do not be put off because of the long "Booting <romname>" screen as FP Open plays the boot animation very late (unfortunately).

=> Image

• Aaaand we are in!
