Hello and thanks for the reply

Well situation is kinda messy, I have devices that are viewable on the network and some that are not. Issue is there are units with 2.0 firmware and when I updated them to 2.8 they stoped showing on the network. I got chips and adapter for eeprom for control board so I need to try and flash new chips with file that is for that use and not these updates that are for devices that are working. Probably your control board died... or some part of it...
