Hello, I Updated my Sony Smart Wireless Headset to new firmware 0.1.E.1.6 and started having problems to use it to call in skype or LINE, it is imposible to make it work. I have tried for 2 day configuring bluetooth but didnt work. Please tell me how i can downgrade to previus version of FW. Now I only can use it to listen to music but no to call. I used to frecuently use skype and line with this headset. Thanks.
