I can not get the Yun reset to factory condition by pressing the WLAN reset button for 30 seconds.
I have simply created a file in ~root and exepect that after a successfull reset to factory condition, this file should be gone, right ?
I am bugged. The arduino is also rebooting by itself regularily, i got rid of this problem by factor reset on anothrt
arduino, but can't get this one reset...
I'm not sure I got your question: do you wish to reset to factory to stop the yun from rebooting itself?
The yun reboots because it can't join the wifi you've configured. When it does and it gets back to access point mode, the webpanel will show a textarea with a lot of (cryptic) information you can attach to this forum to get support.
Most of the times the issue is with your home wifi hotspot: that was the main issue we had while developing the yun
