Hi, 
	I updated my XR500 to DumaOS 3.3. 
	I used the instructions from the forum.
 
	1. intermediary firmware
 
	2.DumaOS33 rc14 
	Unfortunately, I haven't been able to access the router since then. 
	When I call up the IP or routerlogin.net, the login window appears, after entering the login data DumaOS is not running appears 
	I can only access the router via adv_index.htm. 
	Reset already done. 
	I also tried downgrading to r10. 
	Other computers or browsers don't help either. 
	Have I destroyed the router now? 
	Would it help to install the original firmware from Netgear?
 
	Thank you
