Can you connect it now?

no i cant

Try to repair it using SUS. If that doesn't work flash the 1.205 firmware with FlashTool.

Just make sure you have an ulocked bootloader if you are gonna flash. I suggest you visit a Sony Centre and let them repair/replace the phone, because this doesn't really seem to be your fault

[daverawle]

No, flashing with FlashTool does not require an unlocked bootloader ot root and as it uses official Sony firmware probably doesn't affect the warrenty. However, I agree that a visit to a Sony service centre would be the next move if a SUS repair doesn't work.

thnx! repaired it using SUS!
but the battery is draining too fast!!!!

Turn off NFC, reduce brightnes to a low level, turn off 3G/4G (use Wi-Fi instead), disable Bluetooth, turn the LED bar off (if it's always on)

if the battery drains too much during sleep install Wakelock Detector from the play store. It will show what apps are keeping the phone awake.
