Updating wii firmware without internet
If you do not have an ISP programmer already, take a look at this USBasp with 10pin and 6pin, 10pin 5V and 3.3V Version or this one with 10 pin header.
For boards with a 6pin header you may require a 10→6pin adapter like this one.
Changelog Pinout of image 1 is the look onto the pins on the kkboard.
If you build your own adapter, make sure that the programmer you use coresponds to the pinout shown above.
The Orange RX RX3S 3-Axis Flight Stabilizer V2 and Orange RX RX3S 3-Axis Flight Stabilizer w/DSM2 can be flashed with the Open Flight Stabilizer firmware from noobee.
An ISP programmer interface is required to connect your PC to your controller board.
You can then flash a firmware file from your PC, or from the Internet, by selecting from a list of the latest available firmware.
The software will save your settings when you exit, so you will not need to set up everything again when you next launch the software.
I am currently looking for volunteers to translate the tool into additional languages.
I also have tested many different styles of USBasp's from e Bay and other sources.
They generally work very well however, you should always confirm if they work with avrdude.
If you have a USBtiny the flashtool newer than 0.33 and older than 0.63 beta 11 will not work with until you replace the and in the folder /lib/avrdude/windows/ with the one in this download.
Since 0.63 beta 11 the usbtiny part of the flashtool is fixed.
To run the software you need at least Java 6 or greater. Available languages are: Brazilian, Chinese, Danish, Dutch, English, Faroese, French, German, Italian, Swedish, Spanish, Polish, Portuguese, Russian, Turkish, Slovakian, Czech, Korean, Hebrew, Croatian, Greek, Japanese, Romanian, Hungarian, Bosnian, Serbian and Norwegian.
