@aimar wireless display is only supported via the Miracast protocol, and even so it may not work. Most Sony and Samsung monitors work and the Microsoft Miracast adapter is also sure to work.
While connected via wireless you can still surf the web, yes.

@aimar said in MicroSD read only OTA25?:

Maybe I am wrong

You're not ^^

@Flohack maybe I did not explain it clearly. My device is now booting properly without any fix.
I do not need to reinstall it.
I thought it may be an interesting information to those who are still struggling with the boot isuue.
Thank you anyway.

done.
wiped, reinstalled and working like a charm.
