So I got a new OnePlus 7t pro used but in mint condition from eBay and was wondering how to check if the phone is legit and not fake. The IMEI is clean and I downloaded the OP diagnostic app and everything came back good. Someone on a different forum recommended I use the OnePlus Unbrick / Factory Tool. They gave me this link: https://forum.xda-developers.com/oneplus-7-pro/how-to/guide-mega-unbrick-guide-hard-bricked-t3934659 but my model number is not listed in the thread. Does that mean that I can't use the tool or is there a different tool for my phone. BTW my model number is HD1925. Thanks for any help!
