Default Hauwei Vitira passcode/gesture removal?

Hey guy, I found a Hauwei Vitria at work and placed it in Lost & Found at work. At the end of the day, no one claimed it so I took it. It was a MetroPCS company based phome, same as my service provider, but it had a passcode (Numbers) I thought of one solution, factor reset, but then I noticed they had 'Clean Master' so they knew what they were doing with this phone. So I decided to see how I can bypass that code without wiping the data the phone has! I tried researching every way possible. Only to find out at the end, Bootlocked. And to get rid of that, rooting it will delete the data... I dont' like that idea. Help!

I was trying the Aroma File Manager method using CWM Recovery. I have all the necessary files, but the option "Install zip from sdcard" option will just not show up!
