Phone broken after Oreo 8.0

[Buggyphone]

1 Hour ago I updatet my xperia xperformance to oreo 8.0. But the installation process doesn't stop. It reboots all the time, after I typed in the PIN to start Android. At this point it displays a screen similar to the screen from old tv when you arent on a channel.

In the internet i find nothing for this problem.

What can I do?

Could you remove the SD and SIM cards and report back, if that doesn't work, then repair it with XC and report back.

Well, I dont have a SD card 😕

I removed the Simcard whatsoever.

Yes, Support told me that aswell. I think it would even fix my phone, but I want to save my data first. Most importantly the pictures, videos and contacts, maybe if possible also the notes.

On the wide nets of google I can't find a solution for that without having USB-Debug activated(which I don't have).

I am pretty desperate now. Can't even use my onlinebank without sms tan :'(

I'm sorry to say this but if the phone doesn't turn on, you can't get the pictures nor videos.

I'm totally desperate too.

I launched the firmware update 4 hours ago and I have the exact same symptoms !

SONY logo "powered by android" then XPERIA animated logo, and finaly hang after a while, than strange broken display before the reboot. Etc. Ad lib.

My phone is a french dual sim 64GB xperia x performance, with no sd card mounted.

I totally hope there will be a solution allowing me to get my data back.

Edit : of course I tried everything related to safe mode following these steps : https://support.sonymobile.com/global-en/xperiaxperformance/kb/0231018877589a7b01429399b11c00699b/

I also tried to use Xperia Companion but, of course, the phone is never seen by the application.

I tried holding basically all buttons while powering the phone, with or without USB cable.

Nothing never happens, but the phone is still identified by EMMA (flash tool) but the bootloader is not unlocked, and I cannot do that from what seems to be a bricked phone.

I'm more and more mad each time I try to figure out how to get out from this situation.

I'm afraid I don't see many answers from Sony...

Definetely my last Sony phone

Ok, thank you Sony for this now recurrent uselessness when it comes to help your users. I already did my best in the past to document, describe and follow the answers regarding a very annoying bluetooth bug with a previous android update. Beside "please update with "PC(/Xperia) Companion", "please factory reset", and random IT advices (AKA "have you tried turning it off and on again"), we are not treated like valued consumers here.

I'm also done with sony phones.

For the record, I tried a lot of things and read everything regarding data recovery when stuck in bootloop, and it's useless, you can just get a working again phone with everything deleted when using the Xperia Companion repair feature.
