Hi, I got a macbook pro a1502 emc 2835. I am not able to install or start osx on it. I already tried recovery, internet recovery and installation with a usb drive.. with al 3 options it keeps loading with the macbook logo but remains loading.. I also installed linux (limeos) on it without problem. But no luck with mac osx. Can anyone tell me why it is always stuck on the apple logo with yhe loading bar. Even though the loading bar goes till 100% after 40 min. But no luck.

I had similiar problem like yours. Tryed everything but nothing worked. Only the USB option worked for me, but with using a usb stick 2.0 not 3.0 . I losted many hours trying with the usb stick 3.0, but nothing. So download the OS from internet and boot it on the usb stick 2.0 (16gb stick or more) and try again to boot the stick. I used balenaEtcher to flash the OS on the usb stick.
