No matter what ports or PCs I used, it got stuck at the exact same place. Now my phone is having bootloop at the Sony screen, it just turn on, showing the sony brand turn off again and loop continuously. I even try to flash back the 10.5.1.A.0.283 firmware but still stuck at the same place as above.

I have been figuring out for a few hours but with no luck. What can I do now to revive my phone?

Any help is appreciated. Thanks!
