After updating my xperia x to (3.0.0.8), it is not booting. [answered]

ı read the intructions that it is explaining the updating procedure from android to sailfih. I did not update my xperia from android to sailfish 3.0.0.8, it was from sailfish 2x to 3x.

Did you read the posted article? Where did you find that it is about updating from android? Can you post the text? The posted article is about: "If your Xperia is not starting up normally or not starting up at all, you can attempt to fix your device with the help of the Recovery Mode. This article will provide you with step-by-step instructions on recovering a malfunctioning device."

1.1 When should I use Recovery Mode?

You are experiencing problems starting up your device.
Your device doesn't start past the Jolla logo.
Your device seems to never complete the startup process, before restarting again (AKA "boot loop", starts up to "Jolla logo" but no further).
Your device starts up to a state where it is unusable because of a corrupted or not visible user interface.
Some parts of the Sailfish OS system seem to be missing. For example, opening Settings crashes the phone or Settings opens as a blank screen.
You were instructed by Jolla's Service & Support personnel to use it.

But it's of course a complicate workaround. You need some experience to use the recovery mode. There is also the possibility to reflash your device.

Thanks for your additional explanations.
