Hi guys,
I'm from Brasil.
I have a Sony Xperia C2304 dual chip mtk6589 and need help.
After installing with sucess a CWM recovery and a Z3 rom, I made a big mistake trying a z2 rom. Mi phone is now bricked (I don't understood for sure if hard or soft bricked) the buttons doesn't respond, it's impossible to boot in flash mode. When conected to the wall charger or at usb I have only a red led, no vibration nor sound.
My PC with windows 7x64 find a unknow hardware, when forced to install MTK VCOM drivers and using SP Flash it says about base-band protected chip needing a authentication file .auth .
Can someone help me?
Thanks and sorry for my bad english.
