Hi, 

I downloaded all the files necessary for the update, and completed installation. 

I certainly fully - charged uboom L.  

I opened the upgrade tool and tried to connect the uboom l device, but nothing happened. 

The tool application can't detect any device .

I tried with several usb 3.0 data cables, and other usb ports. I even tried with my desktop pc and notebook. 

It's not working on both computers. 

I don't know how to solve this problem.

Hi friend,

 

Thanks for choosing EarFun. Sorry to hear that.

 

We kindly suggest you uninstall the installation tool and download it again and try another device to upgrade the firmware.

 

Update Notes:

1. Please fully charge the speaker first. (If the speaker is not fully charged and plugged into the laptop, insufficient power supply will cause the update to fail.)

2. Please use the USB 3.0 cable with data channel to update the firmware (the included cable and the USB 2.0 cable don't work).

3. Press and Hold the “Bluetooth button” , and then plug in the USB-C cable with UBOOM L.

4. Place the speaker on the desktop, do not move the speaker or the cable while updating.

5. If the update is unsuccessful, please try again a few times.

 

Hope the above suggestions work. 

 

Sincerely,

 

EarFun Customer Service Team

I also sent E-mail to customer service about this, they told me to use it anyway, it wasn't any helpful and the customer service was irresponsible.

Did you load the new firmware in the tool first? The manual doesn't mention it, but it seems to be needed.

When I opened the tool the first time, a new window opened to load new firmware, as the manual didn't mention this, I closed this window. When I connected the speaker nothing happened. After first loading the new firmware in the tool, the speaker was immediately detected.
