Help Nexus 6 is stuck in a boot loop HELP

[Nexus 6 stuck in bootloop]

I have recently bought a Nexus 6 from motorola, it asked me to do a software update (think it was to marshmallow) and after it finished it said 'optimising all # of # but when it finishes it restarts and does it again. Help! Thanks!

Try holding power button down and see if it will turn off and turn back on and see if it will boot up.
And see if you can get into recovery mode if the above doesn't work,While in recovery mode,Clear cache/Data and then see if it will boot up.

I have restarted it manually and it didn't fix. I also have done both factory reset and cleared the cache and it still happens. It happened after during an upgrade to 5.1.1

Co worker brought me a Nexus 7 tab stuck in boot loop Monday. I had never fooled with Nexus devices before. Found this thread, downloaded Nexus Root Tool Kit, followed instructions and had it working in less than a hour. Hope it helps.

Do I need to enable USB debugging? Because I can't get onto the OS to turn the option on :/

No, had same situation with tab. Did everything in fastboot. Program is automated and very simple to use. Only being familiar with Samsung devices, fastboot and adb kinda freaks me out but this tool kit rocks for a beginner.
