All you have to do is open the unlocker software and do Write Backup. You'll have your signal back.
File you need is on the same folder as the unlocker software called backup.

Woops, you wrote this back in May, my bad... 🥰
I would normally go with AOSP and LineageOS.
Arrow used to be my favourite due to speed, I laways obtained insane speed test results in the past, but didn't try it here.
But since I'm a busy man, and have high expectations, I have stuck with Pixel Experience Plus: https://github.com/ponces/treble_build_pe/releases , but if you have complaints, then I suggest AOSP or LineageOS

Flashed the new Pixel experience build of Android 13 dirty over 12.
It feels far snappier, quicker, and responsive... Feels lighter...
Feature wise, I haven't discovered anything new.
I haven't tested NFC, and I haven't had fingerprint for ages to test, so I can't talk to that, but so far everything works afaik...

I actually have never tried that, so I tested it right now, and the screen recording I made of a YouTube clip guitarist, sounded exactly the same on playback... 🥰🎊

    Introducing this Guide​

    Hello there and welcome to My Guide for Your Xperia Smartphone. This Guide will walk with You thru the whole Process of installing Drivers, getting an unlock Key for Your Bootloader, rooting with Magisk and even flashing GSI Custom ROMs up to re-locking Your Bootloader and re-flashing Stock for the total Factory Reset. This Thread/Guide is not meant as Wiki n'or will it teach You about Android at all. Inform Yourself using Google to enjoy the total Freedom and Customization of Android... If You can't solve Problems Yourself, by communicating and research, don't touch Your Bootloader!
    ​
    IMPORTANT:
    2020+ Xperias are using fastbootd, and equivalent to fastboot which runs in Userspace (Same as Recoveries).
    You can access Your Recovery on Your Xperia by holding VolumeDown (-) & the Powerbutton (Your Device needs to be turned off before ofc). Release the Powerbutton after the Display turned on and hold VolumeDown (-) until You see the Recovery Screen. From there, You can enter fastbootd and fastboot. Labled as "Fastboot" for fastbootd and "Bootloader" which is the old fastboot. You can flash Kernels, Recoveries and other stuff from fastboot. Everything else like System Images (GSIs for example), Product Images, System_ext Images and any Userspace stuff has to be flashed from fastbootd. 2019 Xperias are still using fastboot only...
    Fastboot and Fastbootd has nothing to do with SONYs Flashmode on Xperias!

    19. Code: 
      fastboot -w
fastboot reboot
      Note: Your are unlocked and rooted now! Enjoy Your Unleashed Device :)



    5. GSI flashing with Fastboot:

    Note: GSI ROMs can be found around the Web. Like here...

    Treble-Enabled Device Development A/AB ROMS

    Treble-Enabled Device Development A/AB ROMS
    forum.xda-developers.com forum.xda-developers.com
    Not all GSIs require the vbmeta change. You can use all GSIs that are made for ARM64 + A/B Devices. Play around. Systems can't damage Your Device since You keep the Stock Vendor & Kernel! You can use any Android Version! Don't forget to make backups if needed. You are going to Format Your Device!
    • Download a GSI Zip from Google
    • Extract the system.img and the vbmeta.img to Your Platform-Tools
    • Connect Your Device in Fastboot Mode and use Fastboot with:
      (On 2020+ Xperias run: "fastboot reboot fastboot" first after You booted into fastboot)
      Code: 
      fastboot flash system_a system.img
fastboot flash system_b system.img
[Optional] fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta.img
[Optional] fastboot --disable-verity --disable-verification flash vbmeta_b vbmeta.img
fastboot -w (This does Format Your Device and is needed everytime You change the GSI!)
fastboot reboot


    6. Bootloader Re-Lock:
    • Flash the latest Firmware for Your Device with EMMA
    • Erase all Userdata before You continue (like with fastboot -w or via Recovery)
    • Just go into Fastboot mode and type in the command prompt (like before in this Guide):
    Code: 
    fastboot oem lock
    • Wait for Your Device and disconnect it from USB
    • Done... Continue with Step 7.
    7. Firmware Restoring after Re-Locking:
    • Download and Install the "Xperia Companion" from SONY
    • Open the Xperia Companion and select Software Repair
    • Select that Your Device can't get recognized (or is a Smartwatch 3 lol)
    • Go to the next Page and select the Xperia Smartphone Option
    • Continue and wait for the Initialization
    • Press and hold Volume DOWN while connecting to USB (You will see the Green Flashmode LED again)
    Continue once Your Device gets recognized and let the Xperia Companion do his work...
    Done. Your Bootloader is locked again and almost all of Your DRMs are restored.

    Excuse my newbnessness, Respectfully...

    Is there any particular reason we're not using TWRP? or is it just an option? or is it to do with this A/B Treble stuff? or just because it can be done without?

    lol :D

    Older Xperia like 2019 and back are using the Kernel for the Recovery. Means we always need a new Boot Image once we get Updates. We don't get updates anymore and newer Xperias have an extra partition for the Recovery. So if someone is willed to build TWRP that works with the latest Stock Firmwares it would be nice. But we don't have one yet so the only way is this Guide... Sadly

    You just need to flash vbmeta if You have Issues booting Up an specific GSI. Google provides just Images for that, that we can also use on Xperias. Otherwise just flash the OEM AOSP Binaries from Sony If You want to use GSIs. They May Help on some functionality here and there...
