Trying to update my units. Currently running 3 Solix units and a Helix unit along with 360 in a 5 port box. Helix is updated to most recent and 2 out of 3 Solix units are up to date and networking. I have a Solix at console that is stuck in update 3.900 and will not take 4.130 like others did. SD card is 16gb and formatted to FAT32. I've reset default settings and tried multiple times to redownload. Any help would be appreciated!!!
