After received many new IP Phones 6941 the active load firmware is 8.5.1.22.66. A update to V8.5.3 and V8.5.4 ends successful. For update to newest version of firmware available on store (V9.0.3) in release notes of the available versions V9.0.2, V9.0.2SR1 and V9.0.3 is a version named call V9.0.2s. To this version a update is perform first before a update to V9.0.2 and V9.0.3 can made.
In online store the version V9.0.2s is not available to download. Can you tell me the correct installation procedure to bring up all te IP Phones with model type 6941 from 8.5.x to 9.0.3 and if every step to minor versions is needed?!
