I have version 3.2.5. It didn’t take more than a few minutes for it to update. I think your Zenith 3 will keep updating until you stop it. I’m not sure how to stop it safely and restart the download, though. If you can get to the System button, there's a System Update link there.
Innuous update 3.2.5 problem
I'm trying to update my Innuous Zenith 3 to software version 3.2.5. It's been updating for about 2 hours which seems excessive. I'm reluctant to do a hard reset of my iphone or otherwise try to close it for fear of corrupting the software. Has anyone else encountered this? Any suggestions for fixing it? Thanks.
