I Carried out a maintenance upgrade to 8.1(79) from an older version of 8.1 today which in the main went well, the site had 170ish 5610's and 1608's. The problem I've had is that a few of the 1608's are now dead. There is an activity light on the poe switch and when you plug the phone in you get a flicker of light on the display then nothing. This is a rather large site so can't be sure if these handsets were interrupted in mid flash upload as I did have an issue with one switch which seems to have most of these handsets on it. That switch also has working handsets too and is now working fine.
My question is, can these handsets be rescued? Can the firmware be flashed back into them?
Any help greatly appreciated!
