Hello! I have a big trouble - in my Xperia J I have installed FXP CM10. Finally, I found yesterday a file, which switches internal memory with sd card. I was really happy. But later I had to restore original vold.fstab so I renamed the modified vold.fstab by putting one letter into "vold" and renamed original file to vold.fstab (of course both were in /system/etc). After that I pressed power button and chose "Reboot". And... when SXJ turned off, it has been still dead.
I cannot do with that anything. It doesn't respond to charging, plugging into PC, LED is dead also, flashboot and fastboot mode don't work too. Is the service the only one way to fix that? Unfortunately, my warranty is probably not useful because of CM10 and root...
Please, give me some advises what to do with that until I give that into service.
PS: Ahh, I forgot - when I plug SXJ to PC, Windows says, it has installed drivers for ZEUS Flash Device.
