HOW TO DOWNGRADE VMG3625-T50B FW

ipmDav

Hi

I have a VMG3625-T50B router with a FW V5.50(ABPM.9.2)C0

i want to downgrade the FW in V5.50(ABPM.8.3)C0 because it's the version that my FAI ask for a full compatibility.

When i select the 8.3 FW, the router don't want to downgrade

is it possible to downgrade ????

Thank's for help

I could be your ISP is checking the fw version on device and not letting you downgrade. Check with your ISP about it.
