I bought a pair of T5 true wireless in august. They were working fine until yesterday when the right side started cutting in and out at low volume. Having checked around I saw I should update firmware. I only installed the app today and successfully updated the firmware on left side. The right side updated and just when it said restarting, it failed to reconnect and now it will not turn on at all. I get a white flash from the right side but no blue power on or pairing, no sounds to indicate power. Firmware has croaked the right one by all accounts.
