Can't put custom recovery on Note7

Hi!

A few days ago I bought a Samsung Galaxy Note7 from a friend of mine, but (I knew) that it’s battery is heavily limited, because it cannot work while isn’t on a fast charger. I thought that my USB 3.1 Type-C port on my motherboard fill give enough power to boot the phone, but I was wrong… I tried USB-C to USB-C cable, USB 3.0 to USB-C, USB 2.0 to USB-C, but none of them worked except using the phone via it’s original fast charger. Do you have any advice?

It is the N930F (Exynos, Single) version.

Edit: Now I’m able to boot the phone, but can’t enter to download mode, the phone just turn off when I tried to enter it.

Thanks for your help!
