D80 Boom subwoofer won't pair after v10 firmware update.

[taro]

I bought my Ultimea D80 Boom sound system just two days ago and was excited to set it up.

After upgrading the firmware from v7 to v10, I managed to pair the soundbar with the subwoofer once, but as soon as the system went into standby the connection dropped and I haven’t been able to get them talking since.

I've power-cycled both units, done a factory reset, and held the sub’s Pair button for 5 seconds, but the LED only slow-blinks instead of flashing rapidly like it should in pairing mode.

Support says it could take up to 48 hours to push firmware v1 to me—way too long for something that should work out of the box.

Has anyone else hit this problem? Is there a manual way to downgrade the firmware or force the subwoofer to pair again?

Any tips appreciated before my brand-new speakers become expensive paperweights. Thanks!

What you’re describing sounds like a synchronization issue between the soundbar and subwoofer firmware after the update. Here are some practical steps you can try while waiting for support:

1. Force the subwoofer into pairing mode

• Make sure the soundbar is off (standby only).
• Unplug the subwoofer from power for about 30 seconds and plug it back in.
• Hold down the pairing button on the sub for more than 10 seconds (sometimes longer than 5), until the LED flashes rapidly.

If it only flashes slowly, the sub’s firmware may be out of sync with the soundbar’s.

2. Full factory reset

• Soundbar: hold Vol+ and Vol- on the remote or soundbar for a few seconds until it restarts (varies by model, but this is common).
• Subwoofer: unplug it and hold the pairing button while plugging it back in.

3. Manual pairing

• Power on the soundbar.
• Press the PAIR button (or hold it, depending on the manual) until it enters search mode.
• Immediately put the sub into fast pairing mode.
• Wait 30–60 seconds.

I hope this can help you

1. Force the subwoofer into pairing mode
- Tried it, it didn't work.
2. Full factory reset
- Tried it, it didn't work.
3. Manual pairing
- Tried it, it didn't work.

Thank you for trying to help.

We're sorry to hear you're experiencing such frustrating issues setting up your D80 Boom.
In your case, we recommend trying the following steps to troubleshoot and resolve the issue:

Please try the following targeted solutions:
Perform a complete power reset:

Completely unplug the power cords from both the soundbar and subwoofer for at least 5 minutes. This step clears any residual charge in the devices' capacitors and can sometimes resolve underlying software errors.
Afterwards, plug in only the soundbar, wait 1 minute after powering it on, and then plug in the subwoofer. Observe whether the subwoofer's indicator light starts blinking rapidly (entering pairing mode).

Try a wired pairing (if supported):
In addition to wireless connection, the soundbar and subwoofer also have a 3.5mm AUX jack for wired pairing. If you have a suitable audio cable, you can try connecting the two wiredly. This can sometimes force them to recognize each other again, and wireless functionality will be restored.

We hope the above information is helpful and look forward to hearing from you!

I tested this and it didn't work.
I just uploaded a video of this test

If the device fails to pair, it won't be possible to re-upgrade the software. To ensure your experience, a quick solution is to replace it with a new one.
Also, can this device be returned to a third-party warehouse first? Would that be convenient for you to have our engineers analyze the specific cause of the problem?

They let me test the firmware upgrade before sending it back.
I am now waiting for the developer to send me the firmware.
