Hello ~ I recently purchased the UBOOM L, which switched on and paired with my phone successfully.

I wished to downgrade the firmware to Oluv's 0.4.5, which appeared to have work correctly, however when I now try to switch the unit on, I get a flashing power light and cannot pair my speaker with a device. I re-flashed the firmware back to 0.5.0, but that has not solved the issue.

I've tried a speaker reset by holding the power button for eight seconds, and also using the reset switch on the back of the unit.

Can you assist please?

Thank you!!

You need to choose existence UboomL in the bluetooth list and forget it, then connect again. It is written in the firmware instruction
