I was doing firmware update on my phones from the obitalk.com website and one of my phones didnt update and is now dead.
Screen does not power up and only have a RED LED way at the top right. I have tried to unplug the phone and plug it back in. As soon as I plug it back in the LED lights up..
Is there a procedure to fix this?
Try http://www.obihai.com/faq/obi-ip-phone/phn-factory-reset.
See if the unit is able to get an IP address if powered up when connected to a DHCP server. If yes, see if you can get to the phone's web server and try to do a firmware update again that way.
Otherwise I suggest http://www.obihai.com/supportTicketFormA
