SoundJet R1 stopped working after a firmware update? If the device shows unusual lights, won't turn on, or is stuck in pairing mode, follow the instructions below.

Installing incompatible firmware may cause the device to stop working. Contact Avantree Support before continuing.

Upgrade Tool Shows "Relay"

Before You Continue — Do You Also Own an Avantree Relay?

Have you previously connected or updated your Avantree Relay using the same computer or Avantree Upgrade Tool before attempting to update your SoundJet R1?

This information will help our support team investigate why the upgrade tool is identifying SoundJet R1 as Relay.

Stop the update immediately. Do not install firmware version 10.5.1 if the tool identifies the device as Relay.
Disconnect SoundJet R1 from the computer without starting the update.
Take a screenshot showing the product name and firmware version displayed in the tool.
Contact Avantree Support and let us know:
- Do you also own an Avantree Relay?
- Did you update your Relay before attempting to update SoundJet R1?
- Does the upgrade tool still display "Relay" when only SoundJet R1 is connected?

Important: Do not proceed with the firmware update unless the tool correctly identifies your SoundJet R1.

Device Not Working After Update

Symptoms may include flashing purple/pink lights, unresponsive buttons, failure to turn on, or being stuck in pairing mode.

Disconnect SoundJet R1 from the computer.
Connect it to a working USB wall charger and allow it to charge.
Disconnect the charger and try turning the device on normally.
If it remains unresponsive, stop attempting firmware updates and contact support.

Still Not Working?

If the problem started immediately after installing firmware, the device may require technical assessment or replacement. Repeatedly installing firmware may not resolve the issue.

Computer Doesn't Detect SoundJet R1

Use a USB-C data cable that supports data transfer. Some USB cables only support charging.
Connect SoundJet R1 directly to a computer USB port, without a USB hub.
Try another known-working USB data cable or computer USB port.
Check whether the upgrade tool identifies the device as SoundJet R1.

Wrong Product Name Appears?

If the tool displays "Relay" or another product name, do not install the firmware. Contact support instead.

Firmware Recovery Not Working

If SoundJet R1 no longer works after an update and the upgrade tool cannot access recovery mode:

Do not attempt to install Relay firmware again.
Do not attempt an unverified firmware rollback or recovery procedure.
Contact Avantree Support for technical assistance or warranty assessment.

Good to Know:

If firmware recovery is unavailable, the device may require replacement. Do not continue experimenting with firmware intended for other models.

Still Need Help?

Please provide your SoundJet R1 batch number, the firmware version displayed (if known), your computer's operating system, and a screenshot of the upgrade tool.

Also let us know: Do you own an Avantree Relay, and did you update or connect it to the same computer before updating SoundJet R1?

If the device stopped working after an update, include a short video showing the LED behavior.
