Support Not starting/constant reboot after update

http://androidforums.com – Hello all- Bought a Verizon Note 2 from a private party today to replace my out of warranty Galaxy S3 with a broken power button. Activated the phone on my Verizon account, changed out sim card, downloaded some apps, went thru an initial system update and everything seemed fine. A few hours later, I got another system update notice, and clicked download now. The update seemingly finished, and the phone began to reboot. The phone gets the the white print Galaxy Note II screen, then quickly turns back off and reboots. Every 5-10 seconds, that initial screen pops up for a second (General)
