I bought a second hand P9P and was gonna slap GOS on it straight away, but the OEM unlock is greyed out and I'm pretty sure it's not cos it's carrier locked as it is bought through a shop here in Sweden that doesn't sell locked phones (I have a receipt), nor do any carriers lock them anyway, but apparently it's enrolled in the Android Beta Program, and my only guess is that that's the reason it's greyed out? Any ideas on that, or help to roll it out of the beta program as I'm not anywhere near the seller.
