Victron blue smart charger 15amp

Hi i have a 15amp blue smart charger, ive just updated the firmware and now in normal charge mode it keeps flicking between bulk charge and absorption charge evry 10 sec.
It worked fine before is there a way i can downgrade the firmware.

From another thread… (never done this myself so don’t know if it will work for you so proceed with caution and always do a backup before you start)

If you manually download the firmware file from professional.victronenergy.com.

Then on the VRM firmware update page (after running firmware update check) click on the very right of the device on the “upload file” option, this should move it the version you have uploaded.

VC app also has a choose file option, providing you have placed the file on your device.
