Need to access web cache on stock HTC One topic

Hello, I want to access the web cache of the default web browser to access a particular html file that has some information I need. I did some digging around and it seems the cache is not accessible through file explorer apps unless the device is rooted.

Is there any way I can either pull the cached files over ADB (without root) or root the device (even temporarily) without wiping the device. I'm running stock everything with the latest OTA updates.
