how to fix a zuk z1 with no system and no rom (zip file) in the internal storage.

So, i was flashing cm13 and everything went well until i did something stupid. I accidentally wiped the newly installed system because i thought it said 'wipe system cache' but it said 'wipe system' only. I was using cm recovery. I erased the zip file after i flashed so i dont know what to do anymore. Please help me!. i can still go into recovery and fastboot mode and thats all....
