Sony st27i bricked

The above phone stopped mid Sony update now when the phone turns on. (Volume up and switch on .) All I see is the sony logo.
I have downloaded flashtools and the sony recovery but when I hold volume down and turn on the PC does not connect.
Are there any other recovery methods ?

[Q] Help... I Cant Turn Off My Xperia Miro ST23i

Hello, straight to the point I didnt know what to do. Basically, I can't turn it off by using any means. Plus, after a force shut down [take out the battery], it automatically reboot on itself which disturbs flashmode. Means, I cant even install a fresh stock firmware which I had tried more than once. I really appreciate any help. Thx.

Problem : Wont turn off, annoying popup [shutdown box] at screen, power button not working
Take out the battery, hold power button for 10 - 15 seconds, reinsert battery. But first preper Flashtool for flashing, when you see popup connect your phone, try steps above.
Good Luck.

Try connect your phone by USB your PC. It should enter flash mode. Then try to flash Stock ROM ftf without flashing system or userdata (to not erase your current ROM) with FlashTool.
That may reboot your device so it will turn on
