NorthernCottager Posted December 2, 2023 Posted December 2, 2023 I intend to move from Mobilinc to UD Mobile. I am currently running v4.5.4 (not upgraded in ages) and understand that I need to upgrade to 5.0.16 or greater for UD Mobile to work. I also believe this is the highest firmware my ISY will take without loosing Z-wave. When I try to upgrade it tells me: Upgrade failed : Failed uploading file (reported written size is invalid) as well as a Socket timeout Error. FYI I am using a Mac running macOS Monterey 12.6 I read somewhere on the forum that I would first have to upgrade to 4.6.2 but I cannot find that firmware file. Also, not 100% certain as to what the right upgrade file is for the Pro model. Need a little help, thanks in advance.
