Method 1 if your near LIPS or there at a torney ask them to do it or send it in to WDP
Method 2 go to the WDP web site down load the software. Remove grip plug usb cable in to pc then on to the board. It's all on the web site.
Make sure the battery is full when you start it really drains the battery.
The new software is awsome i thought i could shoot fragile paint before with that i shot even more fragile paint
Make a note of your settings before you flash the board so you can put them back in after. Id get LIPS to do it is the easy way to do it
