      Hi,

      Is it possible to get rid of the initial message (just before the Sony logo) " your device has been unlocked...." ?

          Normally not. Locking the device might lead to several issues, and also you cannot reinstall a failed update etc. when the bootloader is locked, as unlocking it will wipe all your data.

          A locked bootloader might also require a signed boot image to be present, and we cannot sign our stuff since we are not the original vendor.

              @lduboeuf I'm not sure.
              On Samsung devices (for example), when you install a custom ROM (LineageOS, /e/ OS, Ubuntu Touch, etc...) there's a yellow exclamation point warning that appears as splash screen a few seconds before the boot animation image from your os takes over.
              This warns you that you have an unlock bootloader / custom rom.

              Maybe it's possible to change this flash image. I could realize it on Xiaomi. Just find a .IMG file compatible for your device (ex: Xperia X), or compile it yourself (mind the resoution), put your device in fastboot mode and flash it from your PC:

              fastboot flash splash mynewsplashfile.img
              

              Don't know if this work on Sony-Ericsson as well...

                  Thank you all for your answers

                    @lduboeuf Normally not. The whole purpose of this message is that it cannot be supressed by a malign firmware or flash. @stanwood it would be counter-beneficial if that would be simply erasable by a flash command. Normally those images are embedded in the bootloader, and so one would need to hack the whole bootloader and replace it.
                    Thats a quite dangerous task, it might hardbrick your phone.
                    Maybe some day we find a way to re-lock boot loaders πŸ˜‰
