Dead st15i (hopefully its softbricked)

[Dvezes]

Hi, I think I've bricked my st15i. I;ve read most of the similar posts and tried most of related tutorials and guides but...nothing.

What I've done:
-Unlocked bootloader
-Rooted
-Flashed custom rom
-Everything was working

Then with no reason, the phone started rebooting. It managed to boot and after 10sec - 1min it restarted again.
To solve this I:
- flashed stock rom and it stopped rebooting but as soon as I plugged it off the usb it rebooted and could not boot (it was looping sony logo and back).
- flashed other stock firmware, the same results
- now when connecting it to pc it goes directly to flashmode
- I can enter fastboot mode as well
- When pressing power button green led blinks
- tried flashing stock firmware again and then both the xperia_relock_bootloader.ftf and Xperia 2011 Range_FreeXperia_ALL.ftf with no results


- when connected to pc it goes only to flashmode (Can't make it to start)
- when pluged in the socket it starts looping up to sony logo
- when not pluged at all when I press power button, green led blinks

I hope you can make any sense out of this because I can't, and I've been trying solutions the past 36hours!!
Please...help!!

The green led blinking sometimes shows you the battery is drained completely

Could you try using another battery of a friend?

And you didn't do an ota update on your unlocked bootloader? Did you try flashing the unbricking ftf?
