When I did the steps to update through the /dev page the git pull didn't go through because I have modified some runeuadio files (runeui.js among others). To force the update I first backed up the modified local files to another location and then used these git commands to force the update http://stackoverflow.com/a/8888015 . After that I had to manually redo the modifications I had previously. I also had to do the wifi setup in Rune UI again.
Is there some simpler way to to update from git when there are a few modified local files?
