edtrac Posted December 17, 2019 Share Posted December 17, 2019 I have 8 CCRs on 1.17 and 4 on 1.07. The 4 older ones will not work on a 500k network so I was trying to upgrade the firmware. Those 4 went fine but two of the 1.17s failed in updating to 1.19. The error is "Invalid Datablock Poll Response". I have not rebooted them yet. Any suggestions?
