sonny.haze , via OnePlus 7 Pro , May 17, 2020 : hi can anyone help me? I have the OnePlus 7 Pro 5G thru Sprint I was able to root it (which im new at but found a guide on xda) and thought that would override the OEM network lock, but it's still greyed out and locked to sprint. I got the damn phone off eBay and thought it was unlocked so I can't unlock it by calling sprint. you can see in my photos the phone has the bootloader unlocked and the phones rooted. Yet still OEM lock in developer menu.
