Error 25 - incompatible firmware

Hi all. I recently updated my 220V/5KW Quattros to firmware v504 and my 150/45-TR MPPTs to v1.61. I'm having an issue where the CCGX doesn't recognise the MPPTs at all but then suddenly does and they come into the display. Based on this I suspect a comms issue, which I'm investigating. In addition, several times a day I get an Error 25 - incompatible firmware fault. Is there actually any incompatibility or is this likely connected to the possible comms issue?


UPDATE/EDIT: closing this question since it has morphed into a "why is my display not reading the swu file" type question so I'll raise a new one.

New problem: the CCGX doesn't recognise the swu file on the USB drive. It is not connected to the internet so can't do an online update so that means I basically cannot update the firmware. Tried 2 different USBs and both read fine on my laptop. Anyone had this before?

Two other things I noticed ... 1. the warning when you insert the USB about not being used for backlogging does not appear, and 2. the extra option to eject the USB does not appear in the menu.

Is the USB stick formatted as FAT32?
