As you can see it took 11 minutes to recognize the phone and flashing only 4 minutes...so something must have gone wrong. Of course the phone doesnt turn on.

What can I do now? Did I do something wrong maybe? Is it the right ftf?

Bootloader is locked btw.

I also tried repairing with PC Companion, but I got Error 100 during flashing (probably not enough battery...).

Is the only way to repair it by removing battery and charge it with external charger? :( I'm afraid that i'll destroy something when I open it...
