Update to failed, phone bricked. How to recover/reflash?

Tried to update Xperia 10II to Update bar reached the end (or at least almost) and then there was message that update failed and to try again later. After that phone boots and sometimes asks for security code but that’s it.
Now I try to reflash it. Phone is off, I hold down the volume up button and connect the usb-cable but instead the blue led I get red led and phone boots to Sony logo and that’s it. How to reflash it in that situation?

How about keeping volume up/down and power keys depressed until you get three vibrations?

And after that? If I should try again with volume up and usb-cable, then there is no difference, still red light.

After removing the SD-card and sim I finally got the blue led and was able to reflash.
