DSU loader option in Xperia 1 Android 11

[jeoleo7]

Hi,

I could see the DSU loader option in the developer settings and I tried installing both of them but it doesn't work. I just reboot to the normal mode after I press restart.

It never comes up with the Guest OS.

Please let me know how to do this. I have Xperia  1 and Bootloader unlocked.

Thanks

I think XDA developers is the place to ask.
