I wanted to install a new Rom (Cyanogenmod 11). Therefor i rooted it (towelroot) and unlocked the bootloader. today i tried to get into flashboot -> CWM. I used the "Flashtool", but i maybe used the wrong CWM.img file, my phone is now in bootloop. I tried to soft reset with Power Button + Volume Up, but it is stuck and only shows the sony logo... now for more than 10 Minutes!!? I solved the Problem! 1. First you need the fresh firmware (Stock Firmware of course!) for your device. 2. You have to push the little yellow button on the backside under the little cover for your sim-card: (Before you do the next part, you should be sure that there is enough battery power left, otherwise your device could die!!) 3. then you have to put it into fastboot-mode (power button + volume up) 4. "Flashtool" will recognize it and then you can click on the lightning in the upper left corner, 5. you tap ok. 6. Then you choose the firmware which you downloaded and 7. you start the flashing process. That's it!! All my data is gone, but my phone works again.
