I can't update the firmware for the Xperia Ear Duo (Xperia Ear Duo)
You might experience that you aren't able to update the firmware for your Xperia Ear Duo if there are objects which emit strong magnetic fields nearby, for example other NFMI devices, or if there is another Xperia Ear Duo unit and charger nearby.
The solution is to keep all other devices and chargers at least 1 metre away from the Xperia Ear Duo when updating the firmware.
