SOMC Flash Device, no flash mode

SOMC Flash Device, no flash mode

I was updating to the latest version of Kitkat (18.3.1.C.0.21) and, after phone restarted the android guy with a red exclamation point appeared, everytime I restarted the phone, that happened.

So, I got the latest ftf file and flashed it using Flashtool. Operation completed with success, however, phone doesn't power on, nothing happens.

No vibration, no SONY logo, nothing.

Tried booting in flash mode but no LED blinking.

Windows does detect a device named SOMC Flash Mode but, that's it

PC Companion can't detect the phone but Flashtool kinda sees it:
15/012/2015 00:12:50 - INFO - Device connected with USB debugging off
15/012/2015 00:12:50 - INFO - For 2011 devices line, be sure you are not in MTP mode
However, that's as far as it goes.
I don't know what's wrong, from a lot of searching, device might be in EDL mode (?)

Anyway, I'll be thankful if you guys help me out.

Bootloader is locked and never touched, if that helps.

Connect your phone to a wall charger > press and hold power & volume up for 10 seconds > let it charge for 2 or 3 hours > then repeat the update process either with PCC or Flashtool

I did what you told me, it's connected to the charger but, how to know if it's really charging? The LED is still off.

Just let it charge for 2 or 3 hours, even if it doesn't look like its charging

After 3 hours of charging, I'm in the same spot.

Nothing happens.
Also, might be worth mentioning, everytime I disconnect it from the PC I need to press the button close to SIM Card to completely shutdown the phone.

Otherwise, he won't be recognized from Windows anymore.
