CI20 NAND Flashing
This is the CI20, if you are looking at this, you probably have one. Flashing a new image to the CI20 is far from a difficult feat
Getting Images
First, get yourself a NAND image from http://elinux.org/CI20_Distros Like the beta Debian 8. or any of the other Linuxes that are presented there. These will be in .img format.
Mounting to SD Card
Hopefully, you have an SD card and a way to connect it to your PC. Plug in your SD card, and get Windows32 Disk Imager (https://sourceforge.net/projects/win32diskimager/). Select your F: drive, and the .img file for Debian 8, Debian 7 or the other NAND images.
Write!
Write it to the SD! (Click "Write").
Ok!
When it's done. Eject the SD card, we will now work with the CI20. See where it says "Boot Select" In the image above? At that place, there are 3 little prongs. The ones labeled 1 & 2 will be shorted by default. Just move the little connector over so that 2 & 3 are connected. Insert the SD card into its slot and turn on the CI20. The little LED will turn red, and then blue. After ~10 minutes the light will have gone back to red. Unplug the power, and replace the connector so it shorts 1 & 2 again. It will now boot with whatever version of Linux you installed.
Please note that your SD card will now be a smaller size than it was (Less storage). Delete all the small partitions and make one big new one formatted to FAT32.
