Hi all, I purchased a Spa3102 (EU) few years ago. Model Spa3102 / ser.no. FM600F212436 / date of manuf. ---. Upgraded the unit a couple of times before, know how to do it. I'm now on softw.vers. 5.1.5(GWa), hardw. vers. 1.1.5. I tried to upgrade to 5.1.7, 5.1.10 resp. Always get "no response from spa" almost immediately after starting upgrade. Tried everything. Via web interface, directly to ethernet conn. & nothing else connected, XP on 'safe mode with network' (no firewall etc.) and so on. IVR works fine, can get the IP addresses, did all resets several times. I can access the 'setup-menu' of the unit in all modes and from the different interface-situations and make configuration changes. Normal operation is fine (except from time delivery to handsets; read somewhere that new firmware might help, that's why I want to upgrade). I looked at several places in the internet (including Cisco), but I covered all the obvious situations already. So I'm running out of options. (Slowly get the idea, that the device just cannot upgrade anymore). Any suggestion are very welcome. Thanks. With kind regards, Kees.
