Few days ago I purchased the lovely C9 pro online from HK, as a regular user I discovered that Knox can't be installed, secure folder isn't active and the disaster that software update (firm ware upgrade) option is missing! So I thought if I Web partition or hard reset from the recovery mode will help to solve this problems but when launched the recovery mode I found one line only.... Custom Binary (Boot) blocked by FRP lock...
Please advice

1)You are facing Custom binary blocked by frp lock because you haven't enabled Oem unlocking option from developers option..
2)Now the way to overcome is flash latest stock firmware for your model no and country using odin
3)What is your model no and country?
4)If hongkong is your country and c9000 is model no then here you can find latest 6.0.1 firmware
