Thank you, I don't realize that. So that means OPPO prevents me to use fastboot? Cuz this is my first time trying to boot it with adb. Otherwise I don't know why Android's DM-verity security mechanism is corrupted.
Like the title, Is there anyway to activate fastboot on oppo F7 (CPH1819)?
I try to boot with adb on my laptop but it doesn't work.
It said: "the serial is not match fastboot unlock verify fail".
