I was reading the sticky guide on unrooting and i noticed that the tampered* mark on the bootloader switches to re-locked*. is there any way to make the phone completely stock again without "re-locked"? i am wondering because i was going to trade my phone in through that sprint one up plan thing going on to get the new nexus 5 and give that a go. i talked to a friend at sprint and she said they wont take the phone if it has been unlocked.
