-In short, flashing is installing new firmware. On a device like a router, firmware is most of the basic programming code which runs most of the major functions on the device. This is similar to the installed operating system and programs on a PC. Just the same, with firmware, updates are released not just to improve usability, but to increase security and protect against vulnerabilities. The device can usually run a without them - however understand the risk this may expose your network.+In short, flashing is installing new firmware.

 Firmware is "firm" because we don't apply changes or updates nearly so often and it's a bigger event to flash firmware than it is to to update software. This is because the Flash RAM memory which stores router firmware isn't designed to be written to frequently. It's also because more things can go wrong during firmware flashing. Firmware is "firm" because we don't apply changes or updates nearly so often and it's a bigger event to flash firmware than it is to to update software.

-Tomato can sometimes retain some NVRAM variables (settings) even after you flash a new firmware image to your router. Therefore, it's very important to erase NVRAM before flashing. Doing so ensures that all variables from the existing firmware are erased before flashing begins. Erasing NVRAM before flashing is an important step that should NEVER be skipped.+FreshTomato can sometimes retain some NVRAM variables (settings) even after you flash a new firmware image to your router.
