I have upgraded my yas-108 firmware to v5.0, but after the upgrade the bass seems to be heavy and doesnot sound good. I would like to revert to v4.0 could anyone please help. V4.0 firmware is not available anywhere in the net
I can't upgrade from Firmware 2.0. I imagine downgrading involves finding the 4.0 firmware and doing the firmware install.
How did you get the firmware to install? I have a proper USB stick formatted fat32 with the proper Firmware 5.0 file on the root of the stick and when performing the directions all I get is the red light which means a problem.
I can not find earlier Firmware before 5.0. Let me know how you were able to upgrade? Thanks
Yamaha support told me today they have pulled the 5.0 Firmware dues to issues. You should go to their support page and do contact us/ chat now during business hours and they can suggest a fix. They told me there is no 4.0 firmware for the YAS-108 and that it went from 2.0 to 5.0.
