I was finally able to get this working today. I tried to upgrade the main panel to 2.7.0 over network and it didn’t error out, it just rebooted back to prior version. Then I tried the SD card method. Same thing. Tried again. Same thing. Changed log level to verbose (was debug), and tried again from SD card, it finally upgraded to 2.7.0! Shortly after the remote fixed itself. All is working now.
I’ve seen the IQPanel be extremely inconsistent in applying updates in the past, and this was no exception.
The user interface on the 2GIG CG2 is nicer, the z-wave was more consistent, upgrades were more consistent, overall a more seamless experience. I may go back to 2GIG if I ever upgrade. Been really frustrated with Qolsys lately.
