[Sony Cross-Device General] Vector Edge:
Please, suggest me how to resuscitate my few hours old phone. :(

Weird situation:

- flashed via Flashtool my few hours old (brand new) Xperia XA Dual 3112 to the latest firmware .3.74

- Flashing completed, but after trying to restart, I got a brick, which only shows me the red led when plugged in the PC USB or wall charger, but nothing else, no charging icon, no respons from the button combinations (for soft or hard reset), no bootloops, no sony or xperia logo, not even black screen ON, which would drain my battery. Bootloader locked. When flashed, I used the latest Flashtool, in SIMPLE Mode (not PRO), with all the drivers installed properly, and I excluded all TA options which were available in right hand, when you choose your firmware. Right before this, I flashed the previous version of the firmware and everything went smoothly...

After reading hundreds and hundreds of posts here, my biggest confusion is: how do I drain the battery totally? There are no bootloops, no black screen on, nothing that would drain the battery. If I connect it to the charger it shows the stable and continuous red led. When connected to Flashtool it keeps saying "Device connected with USB debugging off / For 2011 devices line, be sure you are not in MTP mode". If I leave it alone connected to the PC, after 30 sec Flashtool says "Device disconnected". If I keep pressing the Vol Down or Power button, it keeps disconnecting and reconnecting every 15-20 sec.

Here is the Flashtool log after Flashing the fw:
