I think i bricked it. Pls help

New phone. I wanted to block the marshmellow update. I read that the only way to do that is by installing Package Disabler Pro and checking "software update". I did that and the update notification disappeared but the ~200mb update (or whatever the size it is) was still downloaded and it was taking from the phone's momory so i wanted it gone. I factory reset the phone to remove that update but forgot to check back the "software update" check boxes (there were 2) in Package Disabler Pro. After factory reset the next button from the choose wifi page was grayed out and i was able to continue only after i connected to a wifi network, this didn't happened the first time i configured it. And at the google account page after i enter it along with the password it doesn't go forward, it goes back to the google account page. Any chance to recover from this without losing the warranty? Thanks
