Messed up root directory

[Random_person1]

So the were (alot) attempts to root my phone.

I was installing roms in my phone. Day by day i started to notice my root directory is like seriously messed up.. now what i have noticed is that when i want to install custom recovery it shows that it suceed , but when i want to open recovey it just staying on screen saying "Galaxy J7" and doesnt do anything same when trying to boot up... any suggestions how to fix this? 

(Im starting to think my phone is dead)

@Random_person1: I can't really provide support for third party ROMs, although if you're concerned then you might want to try performing a Factory Reset from the Recovery Menu. To proceed, press the Volume+Power Up+Home button and release all three buttons when the Samsung logo appears. Use the Volume Down button to scroll down to Factory Reset, although please be aware that this will remove all personal data from the phone.
