[Cabunag]

Got this Samsung Note 4 from E Bay sold as new, seems a genuine seller

When i use the the Samsung Phone info app this message come up in Refurbishment Check, this message appears

It looks like the firmware has been modified

WARNING Your phone does not have CSC version

Device usage counter
Headset connect-<root>
Charger connect =3830
S Pen detach=<root>

I have no idea what all that means, i got this phone because you can change the battery, have done must checks to see that its a genuine Model and not a Clone.

Any help would be great this is my first Smartphone, thanks for reading this.

Dial *#1234# on the phone and see what the value next to CSC says. That should offer a clue. (You need a working SIM installed though). CSC is the region code.
