AlfredoM Posted January 24, 2023 Share Posted January 24, 2023 (edited) Question about iPad 5th generation WiFi only model: MP2G2FD/A Can I upgrade from iOS 14.6 to iOS 15.7.3 released yesterday? I loaded the ispw file for 15.7.3 and wanted to restore the ispw file via USB cable via the iMac mid 2020 with Ventura (option key pressed), then an error message came up. Sounded like the software wasn't signed or something I think the iPad 5th gen is too old and too weak for the latest iOS 16.3 right? UPDATE: It's ok, I just updated to iOS 16.3. I googled and it is written that the A9 processor and the RAM are good to work smoothly with iOS 16.3. Nevertheless, I would be interested in how to install an unsigned ispw file on an iPad. thanks for tips Edited January 24, 2023 by AlfredoM Link to comment Share on other sites More sharing options...
