How to downgrade firmware version, because the Q90R with 1012.6 firmware has very low subwoofer

Levstyle — Sat, 20 Mar 2021 16:33:04 GMT

I got the same problem as mentioned in the url

https://eu.community.samsung.com/t5/audio-video/hw-q90r-soundbars-low-subwoofer-with-1012-6-firmware/m-p/2593974#M11182

My Q90R soundbar got a very low subwoofer after updating firmware from 1010.5 to 1012.6，Lots of people who upgrade the firmware to 1012.6 have been suffering the absence of subwoofer。

Thanks you all.

If someone keeps the 1010.5 firmware and can share it would be great. I only keep the 1008 version which is without earc 😞

Should be possible with usb update to go back to previous version.

I actually found the link to the firmware, but usb firmware update doesn't start with older firmware. I assume there is some key combination to force it, but i don't know what it would be.

I just purchased this Soundbar and the sub is super weak. Like barely noticeable at +6 weak. Is this just the product or a firmware issue?

@djsaigon depends on your firmware. if you are at 1012.6 most likely it is the firmware. Otherwise can be something else.

There is definitely a difference in the sub... And if others can't hear the difference then they should not be buying a $1500 sound system.. I'm all about sound quality and this is completely different. Samsung needs to be aware of this ASAP.

Buyers beware... This new firmware has corrupted the Q90r subwoofer, so drastically, that it now sounds like I bought this $1500 unit for my grandma, and plays it like she lives above the church she attends every Sunday while she's watching 2nd graders as they are on nap time....THAT is how loud this sub is now.... Samsung.. Fix what you obviously now know or have known about. As a long time customer and supporter to your products.. Do it for the people who are supportive to your products... This is a big disappointment.

Don't buy Samsung. I just bought another Samsung product (s21 ultra) and also has defects from day 1. Used to be a very loyal customer in the past, but going forward will avoid anything with Samsung badge.

You can always try with support too You can try to change the channels used for the back speakers.
