I have been thinking about getting the ZenFone 10 as well. I have seen a lot of similar posts here and on various google searches. In the XDA forum for the phone there also a topic about not being able to unlock the bootloader/root, but there is a bit more info on the reasoning.

“A moderator in the Asus ZenTalk forum posted that they are working on a new release of the unlock tool and that it should be available in Q3 2023.”

Nice, I do weekly injections, but wanted to make something for others before making one that would suit myself!
