M4 Aqua doesn't react

[EnigeEchte]

Every time when i want to start my M4 Aqua it is stopping at the blue/Purple wave after you see Sony appearing. This is going the whole time until the battery of my phone is empty, when he is 1/2 hours at the blue/Purple wave my phone is starting to get hot. i know that the harddrive of my phone was more than 95% full.

What should i do now? Because i can't get accessoires to my phone now!
