ZD1200 upgrade failed
ZD1200 upgrade failed. We tryed to upgrade a ZD1200 from FW version 220.127.116.11.53 to the latest 10.x version. without any luck. What we see is that the ZD shows the screen that the FW is uploading till it reaches 100% but after it reboots it still shows the 9.x FW version. Meaning the upgrade was not succesfull. We do not get any errors or whatso ever.
any ideas on what the issue can be. A support entitlement is present. We factory defaulted the ZD also no luck upgrading it to a later version
