is there a way i can delete one of my devices from the play store? not hide it but dis-assosiate it with my account all together. i worked on a buddys optimus v and after i downgraded it and rooted it i logged onto my account to check if everything was working properly (had it overnight without access to his account info) then i reflashed a new rom. now it shows up in my devices. i am able to hide it but not delete it. any ideas?
