Had a similar problem as the OP. My unit (Bitfily Snow Panther A1+) was brand new and would not draw an IP. I slid the SD card from the OrangePi Zero into my PC and it was blank! Anyone have a copy of the OS they can link to?? that might get this POS to work...
Try this one below.
If you can't still scan the IP with angry IP as suggested above you must contact the bitfily support the list of contacts are listed on the quoted post above.
For OS, I can't find any OS under their website it seems they don't share it publicly much better contact the support you can use the links above to contact them and ask for the OS.
