These are the steps to install GSI on a device running stock, with locked bootloader:

  1. Unlocked bootloader
  2. Opposite to Sailfish OS here we need latest blobs.I'm on Build 62.2.A.0.533.Simply update with EMMA to latest available version.If you dont update ,be prepared for not properly working or not working at all- notification LED,adaptive brightness,fingerprint etc.
  3. platform-tools installed on your computer: down load them from here. And if you are using windows, you need this driver https://developer.sony.com/file/download/xperia-10-iii-driver.
  4. To flash the vbmeta and GSI images, the device needs to be in fastbootd not in normal fastboot mode. To enter fastbootd
  5. boot to recovery - Hold Vol- _ `Power' until the device vibrates ;
  6. From Recovery menu, choose 'Enter fastboot'
  7. Connect the USB cable two or three times
  8. Check device is visible from PC: fastboot devices (Expected output <Device serial number> fastboot
  9. Flash vbmeta file with this command fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img vbmeta.zip
  10. At this point we are ready to flash whatever GSI we like.All tested by me are 100% compatible with our phones: every LineageOS A14/15 by Andy Yan,Iode OS 5.14 A14,VoltageOS 4.5 A15 and my favorite one e/OS/ 3.1 A15 by Color.This GSI is my daily driver as of now with latest version 3.1-a15-20250817-microG-gsi.I also belive almost ALL GSI`s will work !
  11. When the GSI is chosen we simply flash it with fastboot flash system name_of_image.img
  12. Final steps are to erase userdata and reboot. THis can be done EITHER
    • from the computer using fastboot: fastboot -w then fastboot reboot OR
    • Using Recovery on the device: choose Wipe data/factory reset, then Reboot system now.
  13. When new version of your favorite GSI is available and you want to update,simply make "dirty" flash on top of the old one without erasing userdata. fastboot flash system name_of_image.img
  14. When you wanna test new gsi without loosing data or messing with your daily driver use DSU Sideloader for dual boot!

I recently tried following these instructions to flash this GSI on a Xperia 10 V pdx235 device running SalifishOS. Unfortunately, after completing ste8, the device refused to boot. I then reflashed the stock Sony ROM, using

I booted the stock ROM, and went through first-time setup, before flashing the GSI
