tried for like 4 days to figure this out and came up with a possible solution
first off my c905 cid52 was locked and on orange branded so i unlocked and debranded via ominious
every did as expected but to my dilema mac address was all 0s so i searched and came up witht this
1,flash debrand
when phone started up after flash, do a factory full reset,when phone started up again turn off leave battery out for count of 20 put back in and mac should be there worked for me also leave memory card out seems it blocks wifi ...hope it works for u
