Troubleshoot
As it takes a lot of time to boot (around 10-20 mins) , do not think your phone has gone into a bootloop, its normal .
But if it takes more than the usual time to boot , factory reset the device from Droidboot (fastboot) and then reboot.
Factory reset the device after the first boot if you want to have a pure bug-free lollipop since it is a completely different image from kitkat .
