I don’t know how you can’t understand what is posted because your English seems perfectly fine. Many of us here spend many hours writing how to’s and helping users, 9 times out of 10 it is people not following instructions to the letter as can be seen in this post.
The pictures above clearly show LibreELEC trying to boot.
There is a notice in this sub-forum here that very clearly says in perfect English that if you are upgrading from kszaq LibreELEC releases then no support will be offered.
Read the forums, do a fresh/clean install and if you still have problems then open a thread again.
