======Hardware - Cameras - Lytro - Notes - Firmware Update======

I bought a used Lytro Illum with firmware 1.0.1 (15).

[[http://optics.miloush.net/lytro/TheResources/Archive/Support/202954784-Latest-ILLUM-Camera-Software-Update-Download.html|These instructions]] said to just put the last firmware version file ILLUM-update-2.0.0 (42)-u.lfu on the SD card and turn on the camera with that SD card.

However this worked best for me:
  - Reformat the SD card from the camera.
  - Take one picture.
  - Turn off the camera.
  - Remove the SD card and place it in a PC.
    - //I used an [[https://www.openbsd.org/|OpenBSD]] system for this.//
  - Place the .lfu firmware file in:
    - The root of the SD card.
    - The DCIM directory.
    - The DCIM\100PHOTO directory.
    - The LOST.DIR directory.
    - The MISC directory.
  - Unmount/eject the SD card.
  - Put the SD card into the Illum.
  - Start the Illum.
  - It should now find a firmware update and suggest to update the firmware.
  - Update the firmware.

With these steps I updated:
  - 1.0.1 (15) to 1.0.2 (19)
  - 1.0.2 (19) to 1.1.0 (31)
  - 1.1.0 (31) to 2.0.0 (42)

I probably should have been able to go from 1.0.1 (15) to 2.0.0 (42) with above steps, but by the time I had these steps figured out this was the upgrade route I had taken.
