So, hello. Let's tell about this trouble: in june-jule or like this, i had the error for e shop like region lock or smt else, and after all, I was thinking that the deleting firmware could be fix this problem. And, unfortunately, I'm delete wrong: i don't remember about this instruction, but in general, that's about deleting some files. And that's turned out wrong. Now after this, i can't load the home screen, but to start gm9 or like this, i can. And after switching on the console, after 1 min and more it just black screen and no more. This doesn't show any errors, it just black screen. What shall i do?
