On my Titan X310e, I have Bluetooth bug (after 2 seconds minimum or 2 hours maximum after something that's connected to my Titan, everything turns off and the Bluetooth settings aren't available until after 2 minutes...)

My Wi-Fi quality has decreased a lot (I've 1 and the same phone but the one of my father has 3...)

This 2 bugs are there since I made the last update to arrive to Tango but the HTC update arrived to my phone only after 2 weeks after I had the 2 updates for having Tango and those bugs are there since the HTC Update (didn't had those bugs when I had the Tango update without HTC update).

I tried to do a restore of before the update but it can't do that (Zune says that my phone can't receive the old image of my phone...)

Help!!!
