__ATTENTION! Upgrading firmware can lead to "bricking" your camera. Make sure you are prepared both morally and skill wise. Have your rescue SD card and/or UART adapter ready. Be prepared to de-solder and reprogram flash chip as the last resort. Do not upgrade production cameras unless you really have to!__

are for the fixed-slot layout. NAND cameras upgrade from the NAND package
instead, as in [NAND flash layouts](nand-rootfs-layouts.md).

### Using sysupgrade
`sysupgrade -k -r` gives you the latest release for your camera, as described above; if you wish to revert to a previous image, or load your own updates, then use any of the options described below.
