I have just purchased a used bdp1. I will get it on Friday. So excited as I have been using a refurbished Laptop from like 2010 (which I hate) via usb to my M2Tech Young MK1. My question is, I have read it is a good idea to do a factory reset to get a from scratch version of the bdp when buying used. Will this erase the version of the bdp to an older version? I am not the best with computers. I have no idea what the current version is on the bdp, but if it is a newer version, I would rather not erase it and have to update the player. I am a little apprehensive about upgrading as I see so many people have problems when upgrading. Thanks
