Use at your own risk. There are no support for this but you are likely to have known all these.

So I am at this stage did i do everything right ? Did I chose the correct files, because it stays like this for like a long time, by the way I checked and my board is not dead.

what do you mean by DD command ?

And thank you for quick reply.

Update :

Still no good news
