So I've been spending a lot of time trying to unlock bootloader on my Nexus 5X. I believe the problem that is keeping me from doing this is that whenever I go into the fastboot mode in my phone, the File Transfer (MTP) no longer works and my phone is diconnected from my PC. You know how with Android 6 and 7, every time you want to transfer files to your computer it requires you to go to notifications to allow you to transfer files? If you don't it will only charge your phone. Well I'm guessing that every time I go into fastboot it automatically goes back to just charging the phone and not transferring files. I've looked up ways to make it stay on transfer files by default but you have to root your phone to do that, which is what my problem is keeping me from doing... If anyone could find a way around this, or maybe that's not even the problem. But if anyone can help me so I can root my phone eventually, that would be greatly appreciated.
