Forensic Analysis HTC A9292 EVO 4g

All,

I'm analyzing the physical image of this phone that was performed with Cellebrite and using UFED Physical Analyzer to view the results.

I'm trying to determine if the phone got a factory reset in some point.

I don't have the sd card.

Some artifacts that call my attention were the default wall papers and ringtones. Their creation date suggest me a phone reset but there are other files within the file system back to 2 years. Most of these older files are located in root/data.

Any ideas on how can I confirm the if the phone went through a factory reset or not?

Any help will be greatly appreciated. If there's any other information needed you might need to help me out, just let me know!

Thanks,

Ank.
