Samsung Q990D unresponsive after 1020 firmware update

[Jwrc]

Since the update, the soundbar is unresponsive and can't be reset.

Seems like quite a few people with the issue

But mine is Malaysia version as you can see is XM

I do believe XM indicates some model for Asia/Malaysia. Don't think there's any difference between the actual one.

At least there is some info from a UK Samsung moderator:

"small number of customers"

That's it, the straw that broke the camels back. They can't even be honest. This has clearly affected thousands of people, we're just the ones to kick up a fuss and Google it. Horrible, lazy, dishonest, greedy faceless company.

Last Samsung purchase ever.

Thanks for posting this update tho. At least there's replies related to the issue on UK. Not this forum **bleep**. Not at all!

A small number they say?!!!, we are 165000 viewing this **bleep bleep bleep** community forum all around the world, and the worst thing of this is that I'm in Mexico and support in here is the worst and we dont have pretty laws like UK or US where I can go and throw at their face my Q990D and ask for a new one

I note that the person says that it only affects "a small number of customers".  It would appear that they do not want to recognize the scale of the problem, this and several other blogs clearly show that this is affecting hundreds of consumers worldwide.   I do not consider that to be a small number of customers.

Yeah! Exactly the same here in Australia. Frustrated!! So Samsung whats the FIX??? Replacement!!! mine is 5 months old. Was the best thing out until update stuffed it! NOT happy 😞

My question is my Q990D service USB port is not functioning after applied 1020 firmware, so how do I downgrade to 1016 through service USB port?

[OldButSlow]

Seeing that the official support page shows 1016 and no longer 1020, I tried the upgrade method as downgrade but the behavior is the same. The soundbar shows no reaction to the USB stick and does not update.

The version of the latest published firmware shows:

Upgrade File(USB type),MAIN

• ver 1016
• 1222.15 MB
• Mar 17. 2025
• All OS
• MULTI LANGUAGE

I do not have the sources but some said, that 1020 was Okay if applied via USB and that only devices that received Auto-Updates via WiFi are affected. Some facts from my personal experience:

-my soundbar remains Offline in Smartthings

-my soundbar is no longer an active WiFi client (checked the router settings while the soundbar is on)

-my soundbar did not react to 1020 nor 1016 USBs

I will wait for further instructions from the support, maybe there is a magic trigger for a reset without having to send it in.
