Hello everybodyÂ
Those are generic profiles to be used if there's a method to root the phone without wiping the data, or on already rooted device. In most cases, they cannot be used because you cannot safely root the phone. You should not focus on this method and instead look at Qualcomm Live and MTK Live if phone is unlocked, or bootloader based methods where possible.
@liam2014 not really since they can be only used when if you're able to root the device yourself without wiping the data, which is not something you can achieve on current phones. They're more or less there to just simplify the job in case you get already rooted phone.
