Hi Guys
We currently use HP 4110 and 4120 Lync phone edition phones and I am having an issue with them. It seems that after firmware version 4.0.7577.4366 I am having some instability issues. If I upgrade a phone to .4455 or .4463 some of the phones boot with now issue, other phones will hang on boot and go no where and I need to flash the phone and revert back to pervious version. In some cases I cannot even revert back to the previous firmware version as the phone will not boot either way, to revert back I hold 4 and 6 on the num pad when I connect the network, so I basically have a few phones that appear to be bricked.
This is a recent thing and seems to coincide with my migration to Lync 2013, Lync 2010 is pretty much out the picture but I don't think this is the cause of the issue. Phones were doing this when they got updated from the 2010 front end as well.
Has anyone seen this kind of issue? I have no idea where to even start to troubleshoot this issue and any help will be greatly appreciated.
Many thanks
Joe
