Default Phone reboots every 10 sec, Need to Backup (Rooted w/ TWRP)

My phone keeps resetting every 10sec. After googling, factor reset seems like my only option. But i need to backup my Data (pics+SMS+contacts) only.

Is there a way using Recovery or adb if so please direct me.

This is my first HTC phone and rooting it was not easy (Compered to my nexus phones) but I'm glad i did.

Please help with complete detail
