I am unable to upgrade my ZD1100 from 9.6.1. I am trying to install 9.7.0 but I have also tried installing 9.6.2 with no success. The GUI hangs at upgrading ... 0% and the status indicator flashes red. I did a factory default prior to attempting to upgrade and have tried and reset several times.
Anyone have any suggestions or similar experience?
Old topic, but I recently had this issue and Support had me download Firefox 45 and then surf to about:config, search for and change security.tls.unrestricted_rc4_fallback to user mode. I just clicked on it once to change it and then I saved the settings and performed the upgrade and it actually worked slowly but surely. I went directly from 9.6.1 to 188.8.131.52.44
