Ok so, this is my first post on xda, and because my (sprint) Nexus 6 is stuck on a boot loop. When powered on, goes to googles boot animation, then says "Android is starting... optimizing apps # of 127, and then once it reaches the end, it just goes into the animation again. I somehow have usb debugging disabled, and oem locked. I have no idea what i did to cause this, but esentially I unlocked the phone, and rooted it, and then i tried to disable encryption, and thats where things went south. clearing chache does not help, niether does factory reset. Attempts at flashing factory images are fails. even the guy at sprint cant do it. Besides fixing it, my only other option is to send it in to google and get a reaplacement...for 0. PLease help me solve this issue and i will be eternally grateful :3
