At Bitjump, all of our products are refurbished, but not all of them are upgraded. Refurbished to Bitjump, means that the consoles has been completely taken apart and cleaned. We use an ultra sonic cleaner to clean a variety of parts including consoles shells, motherboards, and other parts. We will also replace parts on consoles like capacitors, voltage regulators, lasers, or other parts that commonly determinate or fail overtime either due to the age of the console or other factors. This varies per console, but you can find details for what has been done in the refurbishment process for a console in the product page under the "Maintenance & Refurbishment Details" section. A console is labeled "Upgraded" when it has some part added to it that provides some sort of enhancement. This includes, but is not limited to, video output upgrades (e.g. HDMI kits, RGB kits), chaging/adding regions (e.g. region switch, swapping region-free bios) replacing original drive with ODE, replacing stock fan with new fan, FRAM upgrades, and more. This varies per console, but you can find details for what has been done in the upgrade process for a console in the product page under the "Upgrade Details" section.
