This varies by company. For instance a factory reset on a Kobo takes the device back to the firmware version originally on THE DEVICE. So a new Kobo Glo bought today has a much newer firmware version "baked in" (call it version C for demonstration purposes) than the original Glo's had (call it version A). Lets say the current firmware is version D and you have both an old and a new device both on version D. On the new Glo a factory reset will only take you back to version C. On an old one it will go right back to version A.
Other companies seem to reflash the "base" version (i.e. Kindle) so when you factory reset it now goes to a version, not the original.
