1. Reboot into recovery
2. switch to rom-slot 1 (also tried the other numbers.. just in case)
3. create the slot, wipe it
4. install zip file ( tried from different folders, on both internal and sd storage)
5. facepalm i'm not sure what to do now i'm slightly sad because it's the seemingly coolest looking rom, there's so much customization options to it.. i just want it hopefully someone out there has an answer, and if not i'll let the subject die for now, thanks for your time to anyone whom reads this.
