Downgrading from android 10 to 9 on Sony Xperia 10 (I4113) no working emma application available

Hello. Looks like there is not a working Emma-tool available for download. Any suggestions, are there other utilities that can perform the downgrade?

Grateful for any suggestions (and if this is the wrong topic, please advise).

Did you search before posting?

Yes, with no success.

What isn’t working? If you need an older version you might want to check archive.org.

But iirc there’s a problem with links having changed from one Sony domain to another. IDK. I never use Windows, and with Linux it’s all possible without Emma.

Thanks for the info. I will take a look att the link.
