So, I purchased a phone from a customer last week and the dummy I am, I purchased it without making sure there wasn't a password. I pulled the battery out to record the IMEI and put it back in and bam, a password screen pops up. Does anyone know of a way to hard reset (hardware button reset) the phone to clear the password?

I've already tried codes with * and #, but they won't work on this phone. Any help would be appreciated. Note: I'm not trying to Network Unlock so Subsidy codes do nothing for me at this stage
